Description:
EDIBLE NON-ANIMAL DAIRY SUBSTITUTE PRODUCT COMPRISING FIBROUS MYCELIUM AS PROTEIN AND INSOLUBLE FIBER COMPONENT AND METHODS OF PRODUCING SUCH

FIELD OF THE INVENTION The invention is in the field of edible non-animal dairy substitute products. The protein component of the edible non-animal dairy substitute products of the present invention is derived from fibrous mycelium mass of edible fungi.

BACKGROUND

In Germany, around 8 million people are either vegetarian or largely forgo meat consumption, and 1.3 million people are vegan. The vegan trend can also be recognized globally, so the number of vegans has increased in the US from 1 % in 2014 to 6 % in 2019. The number of vegan-vegetarian people worldwide is estimated at 1 billion. To satisfy their needs, the food industry is developing more and more purely vegetable alternatives for well- known products. Although over the last years the focus has been on meat alternatives, classic dairy products, such as yogurt or cheese have also become more relevant because of climate discussions, animal welfare and lactose intolerance, in particular in Asia.

Dairy milk consumption has been on the decline for decades, with each generation drinking less milk than its predecessor does. A few years ago, there was usually only one non-dairy milk alternative readily available, which was usually based on soy. Other alternatives existed, such as almond milk, but were not as widely available. This has changed significantly in recent years.

It has been proposed that a part of the cause for this is due to changes in culinary tastes. Furthermore, there has been a shift in perception, especially in the younger generations, that a dairy-free diet is better and healthier. Further motivators to switch from dairy products to substitutes are the increased sustainability linked to the decreased environmental footprint of non-dairy products and concerns for animal welfare.

However, these non-animal alternatives need to have an attractive taste, a pleasant texture and an appealing color to attract more consumers in the first place. The second priority is their nutritional profile, which should be at least as good, if not better, compared to the products they intend to replace. Depending on the global region, sustainability or food safety criteria would rank third in terms of priority.

Non-dairy milk and yogurt are currently the biggest plant-based alternative product category in the US. The majority of the products are based on oat, soy, cashew and almond, with pea and lupins being less prominent. The switch from dairy products, such as milk to alternatives has now extended from milk to include other products like cheese.

Cheese alternatives, also known as cheese analogues, are products used as culinary replacements for cheese. Cheese analogues can also be called cheese substitute products. Various types of cheese analogues exist. Currently, many commercially available cheese analogues utilize a range of additives, such as thickeners, gelling agents, stabilizers and emulsifiers. Cheese analogues comprising these additives, especially those that are chemically modified, are not perceived by consumers as being a "natural food product". Cheese analogues based on nuts, even if combined with gelling agents, do not exhibit a texture/rheological response to match that of cheese, specifically springiness or "stretchability" on baking. They have poor melting characteristics, so that cheese analogues, when present on a heated food product, do not display the stretch associated with regular molten cheese.

Hard cheese imitations are sold as block, sliced or grated cheese. They consist mainly of water, starch, coconut fat, flavor and colors, in some cases with additional plant-based proteins from pea, soy, potato or lupines or nuts like almond and cashew. After blending, these ingredients are heated to the gelling point of the stabilizer and then hot filled and cooled.

Commercial soft and fresh cheese alternatives as well as some hard cheese alternatives can be produced via traditional cheese making techniques as described in WO2018154095A1 by producing an aqueous solution of fruits or vegetables, acidifying it and coagulation by plant-based rennets, followed by moulding and ripening of the resulting curds.

Some commercial cheese analogues currently on the market are based on soy and typically contain casein, a dairy protein, and are hence not suitable for vegan consumers. In addition, soy contains some allergens such as lectins and may therefore not be adequate for those consumers sensitive to such molecules.

Therefore, current dairy alternatives not based on animal products have multiple nutritional challenges:

Firstly, they often comprise allergen-causing ingredients, such as oat (gluten), nuts (almonds and cashews) or soy.

Secondly, their carbohydrate, in particular sugars, and fat content is often significantly higher than animal-based milk analogue products. Thirdly, either they contain less protein or the protein is not complete with the exception of soy-based products. Next to the nutritional effect, this is likely causing a flavour profile further away from the animal-based products as flavour components are mainly formed by proteolysis of proteins and metabolization of the resulting peptides and amino acids by specific lactic acid bacteria and yeasts as described in J.M. Kongo & F.X. Malcata, “Cheese: Chemistry and Microbiology”, Encyclopedia of Food and Health, Academic Press, 2016, Pages 735-740.

Most importantly, they naturally lack valuable micronutrients, such as calcium, iron, zinc, and phosphorus, which consumers seek in dairy products and/or need to seek out in other food products. To compensate for the lack of these micronutrients, some products contain calcium phosphates as food additives.

The last two factors are very critical as consumers rely on dairy products as an easily consumable and accessible source for proteins and calcium.

Furthermore, known cheese analogues generally have an off-taste, which in itself is unattractive, and masking of which by odors and flavors may require labelling of such compounds, which is also unattractive in view of the generally health -conscious consumer market for imitation cheese products. Although the environmental footprint of soy and nuts (almonds, cashews, etc.) is smaller than the one of dairy products, it remains significant. Therefore, there is a need for tastier, healthier and more sustainable cheese substitute products.

The present invention satisfies the above-mentioned needs.

Document US 2020/060310 discloses certain myceliated vegetable protein and certain food compositions comprising same.

Document EP 3’366’144 discloses certain method for preparation of a vegan cheese.

SUMMARY OF THE INVENTION

The present invention solves the above-mentioned challenges by introducing a new raw material to dairy replacement production, namely mycelia of edible mushrooms. Mycelia have been broadly applied in meat-replacement products because of their filamentous structure (GB2137226A) and as fat-mimicking substances in dairy drinks or yoghurts (W02002090527A1 ).

CN212786880 reports that Pleurotus pulmonarius fruiting body is low in fiber content supporting the review published in 2021 (Fungal Biotec 1(2): 65-87 (2021)) summarizing the fiber content of the fruiting body of Pleurotus spp. that ranges from 2.97 wt% to at most 31 wt%, in particular the fruiting body of Pleurotus pulmonarius contains 4-9 wt% fiber on dry basis. CN105054261 also discloses the finding that when Pleurotus pulmonarius is mixed with other strains, a degradation of crude fibers takes place, especially on oyster mushrooms (Pleurotus spp.), thus reducing the fiber content by 2.3-20.25 wt%. Another study in 2020 (Int J Med Mushrooms. 2020;22(7):651-657.doi:10.1615/lntJMedMushrooms.2020035449) also reveals that mycelia of oyster mushrooms (Pleurotus spp.) contains 22 wt% of insoluble fibers. Document US 2020/270559 discloses certain methods of production of edible filamentous fungal biomat formulations and shows nutritional data from two Fusarium filamentous fungi having a total fiber content up to 25 wt% and a fat content between 7 wt% and 12 wt%.

We developed an edible non-animal dairy substitute product comprising, a fibrous mycelium ingredient having at least 39 wt% of insoluble fibers, which also acts as a protein component of the present invention offering an even higher nutritional value compared to dairy products in terms of its high prebiotic insoluble fiber content critical for gut health. Such high fibrous ingredient is not known to be contained with such properties in dairy products.

In one embodiment of the invention, the mycelia are homogenized with water to produce an edible non-animal milk substitute product, also called a non-dairy milk replacement.

In a second embodiment of the invention, this non-dairy milk replacement is converted through fermentation into an edible non-animal yoghurt substitute product, also called a nondairy yoghurt replacement.

In a third embodiment, the mycelia are blended with other ingredients to obtain an edible non-animal fresh cheese substitute product.

In a fourth embodiment, the mycelia are blended with other ingredients and, after coagulation, formed into a sliceable or grateable hard-cheese dairy analogue. Not only is the resulting cheese nutritionally better because of the added complete protein and prebiotic fiber, but the mycelium of the present invention also adds important micronutrients, such as vitamin B2, B3, B5 and B9 as well as key micronutrients like calcium and phosphorus in a biologically active form to the final product.

Flavour can also be significantly improved as the mycelia can bring a natural umami flavour typical to cheese without the usage of additional flavours, especially in the case when mycelium originates from a fungus that forms fruiting bodies, e.g. from Pleurotaceae, such as fungus selected from Pleurotus pulmonarius, Pleurotus ostreatus, Pleurotus citrinopileatus, Pleurotus florida, and Pleurotus salmoneostramineus, and specifically if derived from Pleurotus pulmonarius, or from a fungus selected from Morchella esculenta, Morchella angusticeps, Morchella deliciosa, and Morchella rufobrunnea, preferably Morchella rufobrunnea. This is due to a significant amount of glutamate present in such species along with other amino acids (e.g. aspartate) and/or 5’-nucleotides, which is in large part responsible for conveying the umami sensation.

The present invention is also concerned with methods of producing the above-mentioned edible non-animal dairy substitute products comprising the edible fibrous mycelium mass of the present invention. These methods will be described in detail below.

The present invention is also concerned with the use of an edible fibrous mycelium mass for producing an edible non-animal dairy substitute product, wherein the edible non-animal dairy substitute product is selected from products substituting milk, yoghurt, fresh cheese, whey cheese, cream cheese, medium-hard cheese, hard-cheese, and soft-mould cheese.

DESCRIPTION OF THE INVENTION

In the following, the present invention will be described in detail.

The edible non-animal dairy substitute product of the present invention comprises an edible fibrous mycelium mass in the range of 1 wt% to 99 wt%, and water in the range of up to 99 wt%. In preferred embodiments, the edible non-animal dairy substitute product of the present invention comprises the fibrous mycelium mass in the range of 20 wt% to 95 wt%, more preferably in the range of 65 wt% to 90 wt%. In another preferred embodiment, the edible non-animal dairy substitute product of the present invention comprises the fibrous mycelium mass in the range of 1 wt% to 35 wt%. The ratio of mycelium mass to water can be chosen by the skilled person depending on the product to be substituted. The mycelium can be used directly after fermentation as a wet mycelium, it can be pressed to remove some water, it can be dried to remove water to reach a desired water content. The mycelium can also be dried and water can be added later to reach a desired water content. For example, the water content of the substitute product should be similar to the water content of the product to be substituted.

Preferably, in the edible non-animal dairy substitute product of the present invention, the edible fibrous mycelium has an insoluble fiber content of at least 39% w/w. More preferably, said edible fibrous mycelium has an insoluble fiber content of between 39% w/w and 60% w/w. Even more preferably, said edible fibrous mycelium has an insoluble fiber content of between 40% w/w and 55% w/w. Even more preferably, said edible fibrous mycelium has an insoluble fiber content of between 40% w/w and 50% w/w. Even more preferably, said edible fibrous mycelium has an insoluble fiber content of about 45% w/w. It is to be understood that the weight as referred to herein relates to dry mass of said mycelium. In one embodiment, the edible fibrous mycelium has an insoluble fiber content of at least 40% w/w, preferably of at least 50% w/w, more preferably of at least 60% w/w. As understood herein, the term “insoluble fiber” preferably refers to part of the dietary fiber, which does not dissolve in water. Said insoluble fiber preferably comprises chitin and b-glucan and is preferably distinguishable from the insoluble fiber of plant origin, which comprises plant cellulose and/or hemicellulose, but do not comprise chitin.

In a preferred embodiment the edible fibrous mycelium mass is derived from submerged fermentation. The submerged fermentation allows mycelia to grow without the need for a substrate, which supports them structurally like in solid-state fermentation. Additionally, growth rates are higher as nutrients can be transported to all points of the mycelia and it is easier to maintain sterile conditions. Depending on the fermentation conditions, the mycelia have the possibility to grow in the submerged fermentation into either pellets or threads. This structure is maintained at harvest, giving different texture properties to the resulting products, such as cheese products if processed mildly.

Furthermore, submerged fermentation provides the additional advantage that a clean product is obtained that is not contaminated with the residues of the solid substrates that can bring bad taste or allergies afterwards, in particular because washing of the mycelium grown in submerged fermentation can be easily achieved. Similarly, fermentation byproducts such as acids or alcohols that can alter the taste as well can also be easily removed.

In submerged fermentation, it is also easier to better control fermentation conditions such as pH and oxygen content. Therefore, it is easier to enable the maximal growth of the mycelium compared to substrate limitation in solid-state fermentation. Thus, a more homogenous product composition can be obtained, which also enables reduction of the variation from batch to batch.

Furthermore, the material obtained by submerged fermentation is more malleable and can be formed into any kind of shapes. For example, the mycelium can be homogenized into a liquid that can be fermented, which is particularly advantageous if the mycelium is used to produce a dairy substitute product. Mycelium obtained from solid-state fermentation is usually dried and therefore needs to be resuspended in water to get a milk like substance.

Furthermore, in submerged fermentation, spore formation or fruiting body formation that could lead to toxin production can be prevented easily and efficiently as the fermentation media can be agitated. It is further apparent to the skilled person that if the growth is performed in the submerged fermentation, preferably no differentiation of mycelium to spores and/or fruiting bodies occurs. Thus, it is apparent to the skilled person that the mycelium mass derived from submerged fermentation may also be referred to as non -differentiated mycelium biomass. The skilled person would recognize further advantages of using submerged fermentation, e.g. a better control over texture and composition of biomass compared to solid state fermentation. Furthermore, submerged fermentation methods are easier to scale up, as a second culture can be inoculated with the first culture, as both cultures are in liquid state. This is not easily possible in solid state fermentation, as the first culture cannot flow. This disadvantage can in part be remedied by using a rotating drum reactor, wherein the reactor is rotated to mix the solids and the mycelium. Drums reactors, however, are known for their huge problem of heat transfer during fermentation that leads to different temperatures in the reactor. There may be parts of the fermentation volume that are overheated at some point because heat cannot be removed properly, or parts of the fermentation volume, especially at fermentation start, that are underheated. In submerged fermentation, the heat transfer will be more efficient as liquid is good at transferring heat, leading to more homogeneous heat distribution and thus a more controllable, more efficient fermentation process.

The edible non-animal dairy substitute product of the present invention is selected from products substituting milk, yoghurt, fresh cheese, whey cheese, cream cheese, medium-hard cheese, hard-cheese, and soft-mould cheese.

“Edible” in the context of the present invention means that the edible product is safe for humans to eat. The “non-animal dairy substitute product” of the present invention is a product that is suitable to substitute a dairy product and is not derived from an animal. The “nonanimal dairy substitute product” of the present invention is particularly not a product that substitutes meat. The “non-animal dairy substitute product” can also be termed a vegetarian product, or even a vegan product. Suitability for substituting a dairy product is determined by texture, mouthfeel, taste, nutritional content, water content, appearance, and other factors, which should be as similar to the product to be replaced as possible.

The edible non-animal dairy substitute product of the present invention preferably comprises an edible fibrous mycelium mass having a protein content of between 10 wt% and 60 wt%, preferably between 20 wt% and 50 wt%, and most preferably between 25 wt% and 35 wt% of a dry mass of the fibrous mycelium mass. The protein content of the mycelium mass can be adjusted by choosing fermentation conditions, which control the protein content of the obtained mycelium mass. Such conditions are known to the skilled person and involve adjusting the contents of the fermentation medium to control the uptake and therefore the composition of the mycelium mass to be obtained. For example, the ratio between carbon and nitrogen source in the medium can be altered, such as providing nitrogen in different grades of excess.

The edible non-animal dairy substitute product of the present invention preferably has a phosphorus content from 40 to 500 mg per 100 g weight of the edible non-animal dairy substitute product, preferably from 60 to 250 mg per 100 g weight of the edible non-animal dairy substitute product. In an embodiment, in the edible non-animal dairy substitute product of the present invention the edible fibrous mycelium may have a phosphorus content of at least 1000 mg per 100 g weight, preferably at least 2000 mg per 100 g weight, for example 2131 mg per 100 g weight. It is to be understood that the weight as referred to herein relates to dry mass of said mycelium. In one embodiment, in the edible non-animal dairy substitute product of the present invention the edible fibrous mycelium may have a phosphorus content of at least 120 mg per 100g weight.

The edible non-animal dairy substitute product of the present invention preferably has a calcium content from 20 to 400 mg per 100 g weight of the edible non-animal dairy substitute product, preferably 25 to 400 mg per 100 g weight of the edible non-animal dairy substitute product, preferably from 40 to 250 mg per 100 g weight of the edible non-animal dairy substitute product.

In an embodiment, in the edible non-animal dairy substitute product of the present invention the edible fibrous mycelium may have a calcium content of at least 1000 mg per 100 g weight, for example 1331 mg per 100 g weight. It is to be understood that the weight as referred to herein relates to dry mass of said mycelium. In one embodiment, in the edible non-animal dairy substitute product of the present invention the edible fibrous mycelium may have a calcium content of at least 80 mg per 100 g weight.

The edible non-animal dairy substitute product of the present invention preferably has a zinc content from 0.5 to 5 mg per 100 g weight of the edible non-animal dairy substitute product, preferably from 0.3 to 4 mg per 100 g weight of the edible non-animal dairy substitute product.

Preferably, in the edible non-animal dairy substitute product of the present invention the edible fibrous mycelium has a fat content of 1 to 5 g per 100 g of said mycelium, preferably 2 to 4 g per 100 g of said mycelium, more preferably 2 to 3.5 g per 100 g of said mycelium.

The phosphorus content, the calcium content, the iron content, the manganese content, and/or the zinc content of the mycelium mass can be adjusted by choosing corresponding fermentation conditions, which control the respective contents of the obtained mycelium mass. Such conditions are known to the skilled person and involve adjusting the contents of the fermentation medium to control the uptake and therefore the composition of the mycelium mass to be obtained.

The above-mentioned adjustability of the composition of the mycelium mass of the present invention provides the advantage of versatility, wherein the composition of the mycelium mass can be easily adjusted to the requirements of the substitute product to be obtained. If the protein content of the mycelium mass is increased, the amount of mycelium mass in the substitute product can be decreased without changing the protein content of the substitute product, for example. If the substitute product is a certain type of cheese, which is characterized by certain amounts of calcium, phosphorus, and/or zinc, then these nutrients can be provided by the mycelium mass itself, obviating the need of supplementing the substitute product with additional nutrients externally. This decreases the costs of the production method and of the obtained product due to easier handling, fewer production steps, and decreased costs for raw material for the purpose of producing edible non-animal dairy substitute products with a clean label. Most importantly, the nutrients from the mycelia are bioavailable making the metabolic digestion predictable and easy, especially compared to products, which comprise nutrients supplemented externally.

In some embodiments, specifically when the edible non-animal dairy substitute product is a substitute product for yoghurt or cheese, the edible non-animal dairy substitute product can further comprise a texturizing agent, such as agar-agar, edible starch, guar gum, locust bean gum, wheat gluten, cellulose or derivatives of it. The texturizing agents give structure to the product, thereby making it suitable as a substitute product for yoghurt or cheese. The texturizing agent is however an optional component for the edible non-animal dairy substitute product of the present invention. If the water content of the mycelium homogenized with water is kept low by using a pressed or partially dried mycelium having a desired water content, the resulting mass will have the desired structure similar to that of yoghurt or cheese without the need of adding an external texturizing agent. The skilled person will know how to suitably adjust the water content of the mycelium mass to the substitute product to be produced.

The edible non-animal dairy substitute product can also comprise colorants and/or a flavorants, such as salt, extracts and/or spices. In certain preferred embodiments, the mycelium mass itself provides an umami flavor to the product. This is particularly the case if the mycelium mass is derived from fungal species that form fruiting bodies, e.g. from Pleurotaceae, such as fungus selected from Pleurotus pulmonarius, Pleurotus ostreatus, Pleurotus citrinopileatus, Pleurotus florida, and Pleurotus salmoneostramineus, and specifically if derived from Pleurotus pulmonarius; or from a fungus selected from Morchella esculenta, Morchella angusticeps, Morchella deliciosa, and Morchella rufobrunnea, preferably from Morchella rufobrunnea.

In further preferred embodiments, specifically when the edible non-animal dairy substitute product is a substitute product for yoghurt or cheese, the edible non-animal dairy substitute product further comprises an edible plant-, or algae-based fat component, a fat component derived from fungi or yeast. The fat component is preferably in the range of up to 60 wt%, preferably up to 25 wt%, and most preferably from 1 wt% to 5 wt%. The amount of the fat component can be adjusted depending on the product to be substituted. The edible plant-based fat component is preferably selected from coconut oil, sunflower oil, rapeseed oil, palm oil, cottonseed oil, olive oil, canola oil, algae oil, or oleaginous yeast- derived oils.

As it is recognized by the skilled person, an edible non-animal dairy substitute product is preferably characterized by a calcium content of between 80 mg/100g product and 1350 mg/100g product, and/or by a phosphorus content of between 120 mg/100g product and 2200 mg/100g product. For example, typical cheese has a calcium content of 600-800 mg/100g of the product, and phosphorus content of about 700 mg/100g of the product, and an edible non-animal cheese substitute product is expected to be characterized by a comparable calcium content and/or phosphorus content.

Methods of producing edible non-animal dairy substitute product of the present invention

The present invention is also concerned with methods of producing the edible non-animal dairy substitute product of the present invention.

In one embodiment, the method of producing an edible non-animal dairy substitute product comprises a) homogenizing an edible fibrous mycelium mass with water, thereby obtaining an edible non-animal milk substitute product. Preferably, the edible fibrous mycelium mass is derived from submerged fermentation.

The mycelium mass can be used directly after fermentation or after adjusting the water content by pressing or (partial) drying. “Homogenizing the mycelium mass with water” means that the water component of the mycelium mass and the solid components are mixed to obtain a homogenous mass. The water component can be provided by the mycelium itself, for example if it is a wet mycelium, and/or it can (further) comprise water added externally as necessary to obtain a water content similar to the water content of the dairy product to be substituted or to the water content of the raw material used in the process of making the respective dairy product.

In another embodiment, the method of producing an edible non-animal dairy substitute product comprises a) homogenizing an edible fibrous mycelium mass with water, b) heating the homogenized mixture to 25 to 95 °C, preferably to 50 °C; c) optionally adding a texturizing agent, such as agar-agar, edible starch, guar gum, locust bean gum, wheat gluten, cellulose or derivatives of it to the heated homogenized mixture of step b) and stirring the obtained mixture; d) letting the mixture cool down to 20 °C to 45°C; e) adding acid-forming bacteria such as lactic acid bacteria culture or enzymes with protein-digesting properties, and f) mixing the mixture obtained after step e), thereby obtaining an edible non-animal yoghurt substitute product.

Preferably, the edible fibrous mycelium mass is derived from submerged fermentation.

Adding a texturizing agent is an optional step depending on the water content of the homogenized mycelium mass obtained in step a). If the water content is similar to the water content of the substitute product to be produced, then adding a texturizing agent is not necessary to obtain the texture.

In another embodiment, the method of producing an edible non-animal dairy substitute product comprises a) homogenizing an edible fibrous mycelium mass with water, b) heating the homogenized mixture to 25 to 95 °C, preferably to 50 °C; c) adding an edible plant, algae or fungi-based fat component in the range of up to 60 wt%, preferably up to 25 wt%, and most preferably from 1 wt% to 5 wt%; d) homogenizing the mixture obtained after step c); g) letting the mixture cool down to 20 °C to 45 °C, preferably to 25 °C to 45 °C, most preferably to 32 °C to 37 °C; h) adding acid-forming bacteria in particular lactic acid bacteria culture or enzymes with protein-digesting properties; and i) mixing the mixture obtained; thereby obtaining an edible non-animal cheese substitute product, preferably after storing for 1 - 48 h at 1 - 37 °C.

In a preferred embodiment, the product obtained with this method is an edible non-animal fresh cheese substitute product. It can also be an edible non-animal cheese substitute product selected from the group comprising an edible non-animal substitute product for whey cheese, cream cheese, medium-hard cheese, hard-cheese, and soft-mould cheese, which can be obtained without traditional coagulation steps if the water content of the homogenized mycelium mass is suitably adjusted to be sufficiently low. The coagulation steps of traditional cheese making are done to get rid of the excess water provided by the starting material, which is milk. By having a starting material, i.e. the homogenized mycelium mass, which has a significantly lower water content compared to milk, these coagulation steps of traditional cheese making are not necessary.

Preferably, the edible fibrous mycelium mass is derived from submerged fermentation. In another embodiment the method of producing an edible non-animal dairy substitute product comprises a) homogenizing an edible fibrous mycelium mass with water, b) heating the homogenized mixture to 25 to 95 °C, preferably to 50 °C; c) adding an edible plant, algae or fungi-based fat component in the range of up to 60 wt%, preferably up to 25 wt%, and most preferably from 1 wt% to 5 wt%; d) homogenizing the mixture obtained after step c); f) letting the mixture cool down to 20 °C to 45 °C, preferably to 25 °C to 45 °C, most preferably to 32 °C to 37 °C; g) adding acid-forming bacteria in particular lactic acid bacteria culture or enzymes with protein-digesting properties; h) mixing the mixture obtained after step g); i) coagulating the mixture obtained after step h) by adding a coagulating agent to obtain a mixture of coagulated solids and liquids; j) allowing the mixture obtained after step i) to settle; k) separating the coagulated solids from the liquids; and

L) storing the coagulated solids, thereby obtaining an edible non-animal cheese substitute product selected from the group comprising an edible non-animal substitute product for whey cheese, cream cheese, medium-hard cheese, hard-cheese, and soft-mould cheese.

Preferably, the edible fibrous mycelium mass is derived from submerged fermentation.

The method of producing an edible non-animal fresh cheese or cheese substitute product can further comprise, prior to letting the mixture cool down, step e) adding a plant-based emulsifier, such as lecithin, mono- and diglycerides, glycerides, monoglyceride derivatives, or fatty acid derivatives. It is an advantage provided by the inventive mycelium mass and the production methods of the present invention that addition of calcium chloride or other mineral salts, such as calcium acetate to the mixture is not necessary to reach a calcium content desired for a dairy substitute product, as the mycelium mass itself already provides the necessary amounts of calcium.

In the method of producing an edible non-animal dairy substitute product for whey cheese, cream cheese, medium-hard cheese, hard-cheese, and soft-mould cheese, the coagulating agent preferably is a composition comprising a mineral or organic acid, such as lemon juice, or a non-animal based rennet comprising a mixture of enzymes derived from plants, bacteria or yeast.

In the method of producing an edible non-animal dairy substitute product for fresh cheese, whey cheese, cream cheese, medium-hard cheese, hard-cheese, and soft-mould cheese, the edible plant-based fat component is preferably selected from coconut oil, sunflower oil, rapeseed oil, palm oil, cotton seed oil, olive oil, canola oil, algae oil, or oleaginous yeast-derived oils.

The present invention is also concerned with the use of an edible fibrous mycelium mass for producing an edible non-animal dairy substitute product, wherein the edible non-animal dairy substitute product is selected from products substituting milk, yoghurt, fresh cheese, whey cheese, cream cheese, medium-hard cheese, hard-cheese, and soft-mould cheese.

Example 2 - Edible mycelium mass

Two batches of mycelium mass and water were prepared as basis for the production of the edible non-animal dairy substitute products as follows.

Mycelium grown in submerged fermentation is harvested by filtration over a cheese cloth (MilkyWay) yielding 642 g (batch 1) and 550 g (batch 2). After draining the supernatant mechanically by pressure the filter cake containing the mycelium is washed with tap water at a volume of 2 to 3 times the volume of the removed supernatant, and pressed again. This procedure is repeated twice.

For the application examples, the mycelium is used directly after pressing.

For the analysis of each batch 1 and batch 2200 g of mycelium are frozen at -80 °C and dried using a freeze-dryer of company Zirbus technology GmbH (Bad Grund) for the chemical analysis.

Batch 1

After pressing, batch 1 had a dry matter content of 6.09 %.

After freeze-drying, batch 1 contained 92.85 % dry mass of the mycelium and 7.15 % water.

Batch 1 had the following composition based on 100 % dry mass:

Table 1

Batch 2

After pressing, batch 2 had a dry matter content of 9.89 %.

After freeze-drying, batch 2 contained 95.60 % dry mass of the mycelium and 4.4 % water.

Batch 2 had the following composition calculated to 100 % dry mass:

Example 7 - Production of a homogeneous aqueous solution of mycelia for cheese production, followed by traditional cheese processing to obtain edible substitute products for whey cheese, cream cheese, medium-hard cheese, hard-cheese, and Cheddar

100 g of mycelium of batch 2 are homogenized with 200 ml of water. This mixture is warmed to 50 °C and 15 g of coconut oil (Rapunzel) and one drop of lecithin (Cosmothek GmbH, Germany) added and homogeneously mixed. Heating is stopped and when the mixture reaches 37 °C. 0.2 g ME vegan lactic acid bacteria culture (MilkySky GmbH) is added and mixed well.

A: In one variation 30 ml lemon juice are added, stirred softly into the mix to co-agulate the “milk”.

B: In another variation, 25 droplets of a vegetarian commercial rennet (MilkySky GmbH) are added and stirred into the mix.

In both variations, the mix is removed from the heat and not moved for 3 hours. Subsequently the resulting mix is cut with a knife in squares of 0.5 x 1 cm and left settling for another 30 min. After careful stirring for another 30 min, the coagulated solids are transferred carefully to a cheese cloth put into a beaker with holes. After 20 min, when the liquids stop draining from the beaker, gentle pressure is exerted. After standing for 10 min, this is repeated once more. After that, a whey cheese substitute similar in appearance to Ricotta is stored at 7 °C for 3 hours. The edible non-animal cheese substitute product has a granular structure, which can be cut, and a bland dairy-like taste.

The contents of the edible non-dairy coagulated Ricotta like substitute product are listed in the following table 8.
