Description:
Gel particles in cheese

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a cheese or similar goods, containing gel particles with different flavor, texture taste and color and origin compared to the cheese matrix.

BACKGROUND OF THE INVENTION

A wide variety of different cheeses exist, ranging from dry and firm hard cheeses to soft and moist ones. Not only cheese bulk texture can be different but also flavor, color or surface. Origin of milk (e.g. from cow, goat) has an

influence on texture, flavor etc as well. Inclusions like air bubbles (e.g. Swiss cheese like Emmentaler) or microorganisms in air pockets (e.g. Blue Vein cheese like Gorgonzola) are on the market. Moreover, inclusions of fruits pieces, vegetables (e.g. herbs in fresh cheeses) or nuts are well known, too.

Cheese production may vary depending on the type of cheese but in general, it can be described according to Law and Tamime 2010, as following:

1. standardization of fat

2. heat treatment of milk

3. addition of starter culture

4. coagulation and cutting of curd

- l - 5. stirring, heating and syneresis

6. whey removal, hopping and pressing

7. storage for ripening/maturing Within point 5., heating may vary depending on the type of cheese for soft cheese 30-34°C, for semi-hard cheese 34-42°C and for hard cheese 45-56°C.

Chocolate is a fat based crystallized suspension with a melting range of around 27°C to 33°C, depending on the type of polymorph and chocolate (Beckett 1999) . Adding chocolate to cheese during production will consequently result in a melted chocolate, evenly distributed over the cheese bulk without firm and distinct pieces in the cheese matrix.

Cheese with evenly distributed chocolate or cocoa solids is described in NL1005903 CI for example.

In DE10043573 Al a cheese product is described, having 2 cheese phases, one phase of cheese, containing evenly spread chocolate, fruit or other flavors and the other, having cheese with no other addition. A marble like cheese texture is the result of such a set up.

In DE10121913 Al , a sandwich type of fresh cheese is

described; comprising one fresh cheese phase with evenly distributed chocolate or chocolate paste whereas in the two neighboring phases, fresh cheeses with whole chocolate pieces are present. Heat treatment of fresh cheese is not as severe as with soft, semi-hard or hard cheeses and therefore it is possible to mix chocolate pieces into fresh cheeses at low temperatures, namely below chocolate melting. Moreover, fresh cheese can be easily mixed and is more like a spreadable paste, not having a firm texture as the above-mentioned cheese varieties have.

Another fresh cheese type can be produced by high shearing one part of fresh cheeses containing flavors like vanilla, cocoa, chocolate, coffee, fruits etc., and co-extruding it with another, highly sheared fresh cheese with no additional flavors (WO2005099470A1 ) . This type of cheese does not have inclusions but 2 separate bulk phases.

In WO2010038064A1, mesoporous silicon microparticles of 20 μπι are loaded with sensitive food ingredients like oil/fats, vitamins, aromas, enzymes etc., encapsulated by a

crystallized fat or gel layer and then added to food, e.g. cheese.

SUMMARY OF THE INVENTION

The object of the present invention is to create a cheese with gel particle inclusions of different taste and texture compared to the bulk cheese.

These gel particles do not contain any cheese but include biopolymers exhibiting gelling properties as well as other constituents, which are selected from nutrients, structure- forming agents, flavorings, aromas, coloring and/or dietary and non-dietary fibers. Additionally, gel particles may include sub-microstructures such as oil droplets and/or insoluble particles and/or air bubbles. Such gel particles might have a softer, similar or harder texture compared to the type of cheese, such as soft -, semi-hard - or hard cheese, preferably for semi-hard - or hard cheese. In a further embodiment, such gel inclusions may be build-up by agglomerated, small gel particles.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

Gel inclusions and incorporation into cheese:

Biopolymers in the context of the present application refer to polymers made of the edible polymeric building blocks occurring in nature. Primarily, this term comprises all types of structure-forming agents in the form of polysaccharides, which are considered also to include the majority of

hydrocolloids suitable to foodstuff purposes. Examples of suitable hydrocolloids, which may be mentioned, are products such as xanthan, carrageenan or various plant gums, while other polysaccharide constituents, which may be mentioned, are in particular starches, for example cocoa starches. In addition of gel structure-forming polysaccharides, recipes of the inventive food products may comprise other constituents to be counted as biopolymers such as all types of proteins, in particular milk proteins, egg proteins or proteins of plant origin. The content of biopolymers in the gel particle inclusions is generally in the range of 0.01 - 35% by weight. The biopolymer solvent is of aqueous nature, in particular water, milk or various fruit juices. The content of water in the gel particles can vary over a wide range and is generally in the range of 30 - 95% by weight.

In addition to the constituents, which can be termed

functional ingredients as structure building biopolymers and water, the gel particle inclusions further comprise customary other constituents which promote the gel particle inclusion properties and/or consumer properties. Without any claim as to completeness, these constituents include nutrients, for example fats, oils and sugars, flavorings and aromas, for examples sugars, honey, sugar aromas, fruit aromas, alcohol or alcohol aromas, fruit extracts, salt, spicing and

seasonings and similar customary constituents. In addition, food constituents can be present which, depending on their function, can be termed thickeners, structure-forming agents or dietary and non-dietary fibers, and, obviously, the gel particle inclusions can also comprise natural, nature- identical or synthetic colorings and other food additives, as are customary for food products of the inventive type. It is in addition provided that puree and/or pieces for example of fruits, vegetables, nuts, meat and/or fish can be added to the gel particles which can be prepared accordingly to the invention. Moreover, air, nitrogen or any other food-graded gas can be incorporated into the gel particles. Size of inclusions may vary, between 5 μπι to 3 cm, preferable between 1 mm and 2 cm. Shape of gel particles can be irregular or spherical .

Gel particle inclusions can be produced in different ways. One avenue is to generate a conventional, continuous gel network. Such a gel is then broken up into smaller pieces in a mill, a blade mixer, stamping knife or other appropriate process units. Gel particles are then added to the cheese curd and mixed. If the curd is subjected to high shear, gel particles can be added after such a shearing process in order to keep the gel particle shape. Cheese containing gel

particle inclusion is then processed further according to the cheese type. In another possible process, gel particles are created by spraying a gelling solution into hot moist air or in case of alginate, into a calcium bath. Furthermore, gel particles can be dried and added as dry solid particles to the cheese. In another embodiment, gels are cut in very small pieces (below 50 μπι) and then agglomerated to bigger pieces in the size as mentioned before. Such agglomerated gel pieces are the added to the curd under minimal shearing.
