FIELD OF THE INVENTION

The present invention relates, at least in part to, low or non-caloric sweetener compositions based on steviol glycosides, such as Reb E and Reb I, combined with ferulic acid, as well as compositions thereof, such as oral products, consumables, beverages and pharmaceuticals. More specifically it relates to particular formulations of rebaudiosides and ferulic acid that can elicit a pleasant oral sensory experience.

SUMMARY OF THE INVENTION

The present invention relates to formulations with rebaudiosides and ferulic acid that have beneficial properties. The formulations can modify the taste perception of orally consumable products (such as that they can exhibit enhanced sweetness, improved onset of sweetness, improved time and intensity of sweetness, and/or mask bitterness and/or off notes). The formulations comprise Rebaudioside E (Reb E) and Rebaudioside I (Reb I) in varying quantities, as well as ferulic acid, and can exhibit taste characteristics similar to sugar sweetener systems in carbonated (Cola and Non-Cola) and non-carbonated beverages and concentrates, protein-based products, liquid dairy, yogurt, condiments, baked goods, jams, jellies, and spreads. Additionally, the formulations can provide for higher solubility than the individual use of Reb E and Reb I with a taste profile closer to sucrose than individual rebaudiosides, specifically, Reb E or Reb I alone, in some embodiments. Further, the ferulic acid can act as an antioxidant, stabilizing the rebaudiosides with which it is formulated, in some embodiments.

Some aspects provide compositions (e.g., formulations) comprising Reb E, Reb I, and ferulic acid. In one aspect, Reb E is present in the amount of from about 3 ppm to about 45 ppm.

For animals produced for market the formulations provided can be used for changing the taste profile of lower quality feed or enhancing the flavor of feed containing nutrients that may be needed but that have an enhanced bitterness or off-flavor.

In an embodiment, the formulations of the invention can allow for up to 100% sugar reduction in a wide-range of food and beverage products with higher solubility characteristics than from other individual rebaudiosides and known blends, while maintaining the desired flavor and taste profile and providing an onset of sweetness that is almost identical to that of table sugar.

In an embodiment, the formulations can improve the caloric profile of food and beverages for the elderly and the unwell, relative to the nutrients provided. In nutrition drinks designed for weight loss and/or nutrient delivery the taste characteristics provided with the formulations can be very similar to table sugar allowing for up to 100% sugar reduction in food and beverage products while improving overall solubility in higher concentrations and masking enhanced bitterness or off-flavors.

Also provided in an aspect are commercially valuable processes for producing low- calorie composite sweetener compositions comprising the formulations provided herein for use in various food/feed products and beverages.

In an embodiment the formulations of the invention may be produced by genetically modified microbes designed to produce sufficient quantities of otherwise rare, expensive or difficult to extract steviol glycosides. It is apparent that this may be done with a much more limited geographic footprint than that needed for the production/breeding of the Stevia rebaudiana plant.

In some embodiments, at least one rebaudioside and/or ferulic acid is made by a genetically modified microbe. In some embodiments, the genetically modified microbe comprises one or more proteins having UDP-glycosyltransferase (UGT) and/or sucrose synthase (SUS) activity.

Introduction to the Steviol Glycoside and Ferulic Acid Formulations

Many studies have focused on the connection of sugar consumption with obesity and other pathologies such as diabetes. Consumers and food companies alike are interested in calorie reduction through the use of sugar alternatives. There is also significant interest in the reduction of calories for companion animals or the use of sweeteners to make certain feed products more palatable.

Non-caloric natural and synthetic high-potency sweeteners are known, but they often possess flavor profiles that are not as desirable to consumers as natural caloric sweeteners. Thus, it is desirable to develop improved non-caloric sweeteners that can be substituted for sugar and that have a more desirable taste profile. The species Stevia rebaudiana ("Stevia") is the source of certain naturally occurring sweet steviol glycosides. Considerable research and development has focused on the use of sweet steviol glycosides of Stevia as non-caloric sweeteners, but each of the various steviol glycosides have their limitations in terms of taste, solubility or off-flavor. Surprisingly, formulations with beneficial properties (such as improved solubility, flavor (e.g., masked bitterness), caloric profile, etc.) have been discovered.

In an embodiment, the formulations provided can provide the "full" sweetness needed for many food and beverage applications. This typically is difficult to achieve with a single rebaudioside given the off-flavors which may attend to many of them, such as for example Reb A, due to its perceptible bitterness at concentrations above about 200 ppm. More specifically, the formulations provided can provide high intensity sweeteners that may be added to the food product, beverage, or other consumables, such an oral or pharmaceutical composition. The compositions provided, in an embodiment, can comprise about 50 to about 800 ppm of steviol glycosides without the composition having an unacceptable bitterness. Similarly, the bitterness in a composition can be masked but provide the desired sweetness.

While in general the formulations provided herein can be used for lower or non-caloric purposes, there may be instances where when used with other compounds such as protein or protein sweetener the result may be an increase in the calorific value per unit sweetness of a composition as provided herein.

Methods of Production

Steviol glycosides can be isolated from Stevia rebaudiana leaves. Steviol glycosides are used as high intensity, low-calorie sweeteners and are significantly sweeter than sucrose. As natural sweeteners, different steviol glycosides have different degrees of sweetness and after-taste. For example, stevioside is 100-150 times sweeter than sucrose with bitter aftertaste. Rebaudioside C is between 40-60 times sweeter than sucrose. Dulcoside A is about 30 times sweeter than sucrose. Steviol glycosides with known structures include Rebaudioside E and Rebaudioside I.

The majority of steviol glycosides are formed by several glycosylation reactions of steviol, which are typically catalyzed by the UDP-glycosyltransferases (UGTs) using uridine

5 ’-diphosphoglucose (UDP-glucose) as a donor of the sugar moiety. UGTs in plants make up a very diverse group of enzymes that transfer a glucose residue from UDP-glucose to steviol. For example, glycosylation of the C-2’ of the 19-O-glucose of the stevioside yields Rebaudioside E. Any suitable technique known in the art for isolating and/or purifying compounds, such as Rebaudiosides from plants, such as stevia, may be used. For example, Rebaudiosides can be isolated and/or purified from stevia plant material utilizing one or more of the techniques described in U.S. Pat. Nos. 3,723,410;4,082,858; 4,361,697; 4,599,403; 5,112,610; 5,962,678;

8,299,224; 8,414,951; U.S. Patent Application Publication Nos. 2006/0083838; 2006/0134292; 2007/0082103; 2008/0300402; and Chaturvedula, VSP and Prakash, I, Eur. Chem. Bull. 2013, 2(5), 298-302. Such techniques are incorporated herein by reference. Alternatively, the compounds can be recombinantly produced or chemically synthesized using methods well known to those of skill in the art.

In some embodiments, glycosides from leaves, such as Rebaudiosides, can be extracted using either water or organic solvent extraction. Supercritical fluid extraction and steam distillation can also be used. In other embodiments, Rebaudiosides can be recovered from stevia plants using membrane technology. In some embodiments, production of an extract typically includes extraction of plant material with water or an water-organic solvent mixture, precipitation of high molecular weight substances, deionization and decolorization, purification on specific macroporous polymeric adsorbents, concentration, and drying.

In other embodiments, extracts of stevia leaves may be purified to concentrate a selected component of the stevia extract. For example, column chromatography may be used to isolate Rebaudiosides from the other diterpene glycosides. In some embodiments, following chromatographic separation, the produced Rebaudioside may optionally be recrystallized at least once, or at least twice, or at least three times, to obtain a stevia extract containing a desired level of purity of the Rebaudioside.

In some embodiments, an extract used in the formulations provided herein has a purity of about 50% to about 100% by weight, about 55% to about 100% by weight, about 60% to about 100% by weight, about 65% to about 100% by weight, about 70% to about 100% by weight, about 75% to about 100% by weight, about 80% to about 100% by weight, about 85% to about 100% by weight, about 86% to about 100% by weight, about 87% to about 100% by weight, about 88% to about 100% by weight, about 89% to about 100% by weight, about 90% to about 100% by weight, about 91% to about 100% by weight, about 92% to about 100% by weight, about 93% to about 100% by weight, about 94% to about 100% by weight, about 95% to about 100% by weight, about 96% to about 100% by weight, about 97% to about 100% by weight, about 98% to about 100% by weight, or about 99% to about 100% by weight.

For example, an extract used in a formulation provided herein may have a purity of about 50%, about 55%, about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 86%, about 87%, about 88%, about 89%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99%, or about 100% by weight, including any range in between these values.

The purity of Rebaudiosides, such as those extracted, isolated, and/or purified from stevia plants, can be assayed using any suitable method known in the art. For example, chromatography, such as HPLC, may be used to test the purity of Rebaudioside extracts.

In some embodiments, production can be accomplished through the utilization of microbial strains to produce Rebaudiosides in high yield and purity to allow commercial incorporation into orally consumable products (See, e.g., U.S. Pat. Nos. 9,988,414, 9,522,929, 10,010,099, 10,010,101, 10,081,826, 10,253,344 all of which, including the methods of production, are incorporated herein by reference).

In some embodiments, Rebaudiosides may be produced by recombinantly expressing enzymes in a microbial system. In some embodiments, the host cell is selected from the group consisting of Escherichia; Salmonella; Bacillus; Acinetobacter; Streptomyces; Corynebacterium; Methylosinus; Methylomonas; Rhodococcus; Pseudomonas; Rhodobacter; Synechocystis; Saccharomyces; Zygosaccharomyces; Kluyveromyces; Candida; Hansenula; Debaryomyces; Mucor; Pichia; Torulopsis; Aspergillus; Arthrobotlys; Brevibacteria; Microbacterium; Arthrobacter; Citrobacter; Klebsiella; Pantoea; Corynebacterium; Clostridium (e.g., Clostridium acetobutylicum). In some embodiments, the host cell is a cell isolated from plants selected from the group consisting of soybean; rapeseed; sunflower; cotton; com; tobacco; alfalfa; wheat; barley; oats; sorghum; rice; broccoli; cauliflower; cabbage; parsnips; melons; carrots; celery; parsley; tomatoes; potatoes; strawberries; peanuts; grapes; grass seed crops; sugar beets; sugar cane; beans; peas; rye; flax; hardwood trees; softwood trees; forage grasses; Arabidopsis thaliana; rice (Oryza sativa); Hordeum yulgare; switchgrass (Panicum vigratum); Brachypodium spp.; Brassica spp.; and Crambe abyssinica. In some embodiments, the cell is a bacterial cell, such as E. coli, or a yeast cell, such as a Saccharomyces cell, Pichia cell, or a Yarrowia cell. In some embodiments, the cell is an algal cell or a plant cell.

In some embodiments, Rebaudiosides of the formulations provided herein are produced in a reaction mixture including a start compound (e.g., any natural or synthetic compound capable of being converted into a steviol glycoside compound in a reaction catalyzed by one or more enzymes); a substrate selected from the group consisting of sucrose, uridine diphosphate (UDP) and uridine diphosphate-glucose (UDP-glucose); and one or more enzymes, such as a UDP-glycosyltransferase. Suitable UDP-glycosyltransferases for producing Rebaudiosides in either a microbial system or an in vitro reaction mixture include any UGT known in the art as capable of catalyzing one or more reactions in the biosynthesis of steviol glycoside compounds, such as, without limitation, EUGT11 (GenBank Accession No. AC133334), HV1 (GenBank Accession No. BAJ98242.1), UGT76G1 (Genbank Accession No. AAR06912.1), UGT85C2 (GenBank Accession No. AAR06916.1), UGT74G1 (GenBank Accession No. AAR06920.1), or the functional homologs, fragments, or variants thereof.

In some embodiments, the UDP-glycotransferase used in any one of the methods described herein is EUGT11, or any functional fragments or variants thereof. EUGT11 is a UGT having 1,2-19-O-glucose and 1,2-13-O-glucose glycosylation activity. EUGT11 is known to catalyze the production of stevioside to Rebaudioside E. EUGT11 also has 1,2-19- O-glucose glycosylation activity. In some embodiments, the UDP-glycotransferase used in any one of the methods described herein is HV1, or any functional fragments or variants thereof. HV1 is a UGT with a 1,2-19-O-glucose glycosylation activity that can produce related steviol glycosides, such as Rebaudioside E. HV1 also can convert Reb KA to Reb E.

In some embodiments, the reaction mixture further comprises additional enzymes (e.g., sucrose synthase or SUS) to improve the efficiency or modify the outcome of the overall biosynthesis of steviol glycoside compounds. For example, the additional enzyme may regenerate the UDP-glucose needed for the glycosylation reaction by converting the UDP produced from the glycosylation reaction back to UDP-glucose (using, for example, sucrose as a donor of the glucose residue), thus improving the efficiency of the glycosylation reaction.

Examples of enzymes used for synthesizing rebaudiosides

Ferulic Acid

Ferulic acid is a hydrocinnamic acid that is abundant in plant cells, particularly as a component of pectin, lignin, and plant cell walls. In nature, ferulic acid serves as a precursor for the synthesis of many other organic compounds. It is frequently found in edible plants such as com, rice, bamboo shoots, cereals, flaxseed, tea leaves, and legumes. Ferulic acid is common in plant-based foods such as rice bran oil, breads containing flaxseed, and rye bread. Ferulic acid acts as an antioxidant, and can therefore protect the Rebaudiosides with which it is formulated from oxidation, which results in undesired off-flavors. Methods of producing ferulic acid are described in U.S. Patent No. 5,288,902, which methods are incorporated herein by reference. A brief description, which provides an overview of exemplary methods is provided.

Briefly, U.S. Patent No. 5,288,902 provides a method of manufacturing ferulic acid by hydrolyzing oryzanol, which method is incorporated by reference. Briefly, waste material, byproduct or a crude oryzanol can be subjected to hydrolysis in the presence of an alkali so as to manufacture ferulic acid. In general, sodium hydroxide or potassium hydroxide can be used as an alkali in the step of hydrolyzing oryzanol. It is also possible to use other alkaline compounds such as LiOH, RuOH, Na2 CO3, K2 CO3 and NaHCCh. In the next step, a solution containing an alkali salt of ferulic acid can be acidified with, for example, a dilute sulfuric acid so as to precipitate ferulic acid in the solution, followed by separating the precipitated ferulic acid by mean of filtration. The crude ferulic acid separated by filtration can be dissolved in hot water (about 90 to 100° C) and, then, the system can be cooled so as to permit precipitation of ferulic acid. A pure Zrans-ferulic acid can be obtained, which refers to the naturally occurring form of ferulic acid.

As used herein, “nutraceutical(s)” refers to compounds, which includes any food or part of a food that may provide medicinal or health benefits, including the prevention and/or treatment of disease or disorder (e.g., fatigue, insomnia, effects of aging, memory loss, mood disorders, cardiovascular disease and high levels of cholesterol in the blood, diabetes, osteoporosis, inflammation, autoimmune disorders, etc.). Any suitable nutraceutical known in the art may be used. In some embodiments, nutraceuticals can be used as supplements to food and beverages and as pharmaceutical formulations for enteral or parenteral applications which may be solid formulations, such as capsules or tablets, or liquid formulations, such as solutions or suspensions.

In some embodiments, dietary supplements and nutraceuticals can further contain protective hydrocolloids (such as gums, proteins, modified starches), binders, film-forming agents, encapsulating agents/materials, wall/shell materials, matrix compounds, coatings, emulsifiers, surface active agents, solubilizing agents (oils, fats, waxes, lecithins, etc.), adsorbents, carriers, fillers, co-compounds, dispersing agents, wetting agents, processing aids (solvents), flowing agents, taste-masking agents, weighting agents, jellyfying agents, gelforming agents, antioxidants and antimicrobials.

As used herein, a “gel” refers to a colloidal system in which a network of particles spans the volume of a liquid medium. Although gels mainly are composed of liquids, and thus exhibit densities similar to liquids, gels have the structural coherence of solids due to the network of particles that spans the liquid medium. For this reason, gels generally appear to be solid, jelly-like materials. Gels can be used in a number of applications. For example, gels can be used in foods, paints, and adhesives. Gels that can be eaten are referred to as “edible gel compositions.” Edible gel compositions typically are eaten as snacks, as desserts, as a part of staple foods, or along with staple foods. Examples of suitable edible gel compositions can be, for example, gel desserts, puddings, jams, jellies, pastes, trifles, aspics, marshmallows, gummy candies, and the like. In some embodiments, edible gel mixes generally are powdered or granular solids to which a fluid may be added to form an edible gel composition. Examples of suitable fluids can be, for example, water, dairy fluids, dairy analogue fluids, juices, alcohol, alcoholic beverages, and combinations thereof. Examples of suitable dairy fluids can be, for example, milk, cultured milk, cream, fluid whey, and mixtures thereof. Examples of suitable dairy analogue fluids can be, for example, soy milk and non-dairy coffee whitener.

As used herein, the term “gelling ingredient” refers to any material that can form a colloidal system within a liquid medium. Examples of suitable gelling ingredients can be, for example, gelatin, alginate, carageenan, gum, pectin, konjac, agar, food acid, rennet, starch, starch derivatives, and combinations thereof. It is well known to those in the art that the amount of gelling ingredient used in an edible gel mix or an edible gel composition can vary considerably depending on a number of factors such as, for example, the particular gelling ingredient used, the particular fluid base used, and the desired properties of the gel. Gel mixes and gel compositions of the present disclosure can be prepared by any suitable method known in the art. In some embodiments, edible gel mixes and edible gel compositions of the present disclosure can be prepared using other ingredients in addition to the gelling agent. Examples of other suitable ingredients can be, for example, a food acid, a salt of a food acid, a buffering system, a bulking agent, a sequestrant, a cross-linking agent, one or more flavors, one or more colors, and combinations thereof.

In certain embodiments that can be combined with any of the preceding embodiments, the orally consumable products can further include one or more additives selected from a carbohydrate, a polyol, an amino acid or salt thereof, a poly-amino acid or salt thereof, a sugar acid or salt thereof, a nucleotide, an organic acid, an inorganic acid, an organic salt, an organic acid salt, an organic base salt, an inorganic salt, a bitter compound, a flavorant, a flavoring ingredient, an astringent compound, a protein, a protein hydrolysate, a surfactant, an emulsifier, a flavonoids, an alcohol, a polymer, and combinations thereof.

The compositions can be used "as-is" or in combination with other sweeteners, flavors and food ingredients. For use in domestic applications, particularly as a replacement for sugar in beverage sweetening, it is desirable in some embodiments that the compositions according to the present disclosure include a bulking agent so that an equivalent sweetness to that provided by, for example, a teaspoonful of sugar is provided by an amount which can conveniently be handled. Any suitable soluble and edible material can be used, for example, a carbohydrate such as sucrose itself, especially transformed sugar of low density, dextrose, or sorbitol or a dextrin such as spray-dried maltodextrin. While the substances will add to the caloric value of the composition, the total will still be considerably smaller than that of the amount of sugar providing an equivalent sweetness. Alternatively, the sweetening composition may be prepared in a tablet form.

Compositions provided herein are usually stable at pH values in the range of from 2 to 10, especially 3 to 8. Dry compositions, such as powders, granules or tablets can be stable indefinitely when stored under dry conditions at room temperature. Compositions in the form of aqueous solutions can be stable indefinitely when frozen. If a preservative such as benzoic acid or its salts, sulphur dioxide or sodium meta-bisulphite is added to such a composition, it may be stored almost indefinitely at room temperature. The compositions therefore can have a long shelf-life when incorporated into soft drinks or fruit juices, or other similar food compositions containing preservatives. The limitation on the use of sugar may also positively contribute to the long shelf-life of the products provided herein. Food compositions comprising the inventive formulations provided herein may further comprise components selected from the group consisting of additional sweeteners or sweettasting compounds, aroma compounds, flavoring compounds, and their mixtures. Such additives may also specifically include hydrocolloids such as pectins, gelatin, carrageenan, or gums (Arabic, guar, locust bean) for dressings, jams, jellies, confections and the like. Other additives to food, feed or beverage compositions include chelating agents whose addition is designed to protect against enzymatic reactions and may specifically include ethylenediaminetetraacetic acid (EDTA).

Aroma compounds and flavor enhancing agents are well known in the art can be added to the compositions provided herein. These flavoring agents can be chosen from synthetic flavoring liquids and/or oils derived from plants leaves, flowers, or fruits. Representative flavoring liquids include: artificial, natural or synthetic fruit flavors such as eucalyptus, lemon, orange, banana, grape, lime, apricot, and grapefruit oils, fruit essences including apple, strawberry, cherry, orange, pineapple, and so forth, bean- and nut-derived flavors such as coffee, cocoa, cola, hazelnut, peanut or almond, and root-derived flavors such as licorice or ginger.

The following examples illustrate various embodiments of the invention. It will be understood that the invention is not limited to the materials, proportions, conditions and procedures set forth in the examples, which are only illustrative.
