Description

DESCRIPTION OF THE INVENTION

[0022] A first subject of the invention relates to texturized dairy proteins, also referred to hereinafter by the abbreviation (TDP), which are obtainable by [0023] (a) a mixture comprising or consisting of [0024] (a1) dairy proteins and [0025] (a2) a fiber material and/or plant protein, [0026] (b) extruding the mixture in the presence of water and/or whey with application of a temperature gradient from about 20 to about 200 C. and at a pressure in the range from 1 to about 200 bar, and [0027] (c) subsequently depressurizing the extrudate.

[0028] A further subject of the invention relates to an analogous method for producing texturized dairy proteins (TDP), comprising the following steps: [0029] (a) providing a mixture comprising or consisting of [0030] (a1) dairy proteins and [0031] (a2) a fiber material and/or plant protein, [0032] (b) extruding the mixture in the presence of water and/or whey with application of a temperature gradient from about 20 to about 200 C. and at a pressure in the range from 1 to about 200 bar, and [0033] (c) depressurizing the extrudate.
Surprisingly it has been found that dairy proteins can be processed together with plant proteins and/or fiber materials to form extrudates which have any of a very wide variety of different textures dependent on extrusion conditions and subsequent cooling and processing steps.

[0034] Ingredients

[0035] Primary ingredients (component a1) contemplated for the TDP are dairy proteins, specifically whey proteins (concentrates, isolates, hydrolysates) and caseins.

[0036] Whey proteins and casein are the two major protein fractions in the milk from mammals. The protein content of cow's milk, amounting to around 3.3%, is composed of around 2.7% of casein and around 0.6% of whey protein. The designation whey protein is derived from the fact that the proteins of this fraction are the major constituent of the proteins in whey. Whey proteins are a group of various albumins and globulins. In detail these are: [0037] alpha-lactalbumin around 20% (0.1% in the milk) [0038] beta-lactoglobulin around 45% (0.25% in the milk) [0039] immunoglobulins around 10% [0040] proteose peptone around 20% [0041] serum albumin around 5%

[0042] Whey proteins are heat-sensitive. When milk is boiled, it is in particular the -lactoglobulin which is responsible for the skin on the surface. Whey proteins also include a high level of branched-chain amino acids, such as about 20% to 25% of the majority of food proteins. Whey proteins are classed as of high grade in terms of nutritional physiology (high biological value). They are therefore a major constituent of the whey-based protein powders for muscle building.

[0043] The simplest form of whey protein is that of whey protein concentrate. It is manufactured principally by ultrafiltration. It possesses a relatively high protein content of about 70% to 80%. Because of the simple manufacture of the raw material in dairies, it is substantially more favorable than whey protein isolate and hydrolysate. Consequently, it is regarded as the first choice by food supplement suppliers in the manufacture of their products. Owing to a carbohydrate proportion of about 6% to 8% and a fat proportion of about 4 to 7 wt %, the protein content is somewhat lower than in the case of the isolate.

[0044] In the manufacture of whey protein isolate, two different processes are employed. In the case of the ion exchange process, the whey proteins are adsorbed on the ion exchangers and eluted, causing the protein preparations to contain more salts. In the case of manufacture of whey protein isolate by the microfiltration process, no salts are used. As a result it is possible to obtain a particularly high purity, with a protein proportion of about 90% to 96% and also with a low fat content and lactose content of less than one percent. Moreover, whey protein isolate on account of its virtually lactose-free status is particularly suitable for persons with lactose intolerance.

[0045] In the manufacture of whey protein hydrolysate, the hydrolysis process is employed. As a result of the hydrolysis (splitting-up) of the protein chains into very small fragments (peptides), whey protein hydrolysate can be absorbed more quickly by the body. The greater the degree of hydrolysis, the more high-grade and more expensive the protein. A disadvantage to be cited is the bitter taste. Consequently, the principal application of whey protein hydrolysate is in amino acid tablets and capsules, where the bitter taste plays only a subordinate role. In small proportions, whey protein hydrolysates are added to mixtures of various high-grade proteins (multicomponent proteins).

[0046] Casein likewise constitutes a mixture of a plurality of proteins (S1-, S2-, -, -casein), and serves for storage and transport of protein, calcium, and phosphate to the neonate. Casein in milk, together with calcium phosphate and other constituents, forms micelles. Typical examples of suitable casein include not only caseins obtained by acid treatment but also micellar casein from the microfiltration of skim milk.

[0047] In the course of the invention, the finding was made that for the texturizing of the end products it is critical that the extrusion takes place together with plant proteins, which endow the products with a texture typical in terms of sensation of poultry, fish, mushrooms, tofu or else peanut puffs. Furthermore, the addition of vegetable fibers may prove advantageous for the product texture. Such fiber materials may be a constituent of vegetable protein concentrates. Alternatively, fibers are added separately as a raw material (e.g., when using plant protein isolates). The folding of the protein structure in these vegetable proteins has likewise proven, moreover, to be highly advantageous when the aim is to endow the products with a texture.

[0048] Component (a2) is used customarily in a proportion of about 1 to about 75 wt %, preferably about 10 to about 60 wt %, more preferably about 25 to about 50 wt %, and very preferably about 30 to about 40 wt %, and more particularly about 40 to about 50 wt %, based on the total amount of components (a1) and (a2).

[0049] Extrusion and Shaping

[0050] The development of various textures is dependent on the extruder operating conditions. With preference the mixtures of (a1) dairy proteins and also (a2) plant proteins and/or fibers are extruded with application of a temperature gradient from about 40 C. to about 170 C. The pressure gradient is set from 1 bar to about 120 bar.

[0051] The extrusion of the protein/fiber mixtures makes the accompanying use of water unavoidable. Here a distinction is made between low moisture and high moisture processes.

[0052] Low Moisture Process

[0053] In the former case, the mixtures are extruded in the presence of about 10 to about 50 wt % and more particularly about 20 to about 40 wt % of water and/or wheybased on the total amount of raw materials used, i.e., the amount of components (a1+a2) and water and/or whey. The extrusion takes place under pressure, which is a result in particular of the parameters of rotary speed and temperature and is set at about 30 to 120 bar and more particularly about 50 to 110 bar. The extrusion is carried out preferably in a twin-screw extruder which possesses corotating, shear-intensive screws.

[0054] The extrusion takes place, moreover, with application of a temperature gradient from about 20 to about 200 C. and more particularly about 40 to about 170 C. What this means is that the extruder, which possesses an outer heating/cooling jacket and a series of separately controllable temperature zones, has a lower temperature in the front region than in the rear region. A large difference in pressure and temperature between extruder interior and environment is beneficial to the expansion of the resultant extrudates following emergence from the extruder.

[0055] Depending on facility, rotary speeds should be set of about 200 to about 2000 rpm. The preferred ingredients in terms of the components (a1) dairy proteins here are casein and/or caseinates.

[0056] A typical mode of processing of products by the low moisture process involves depressurizing them to atmospheric pressure in one step after they have left the extruder, and bringing the resulting composition into a piece form. Immediately on leaving the extruder, the product still has a temperature of about 120 to about 140 C., meaning that the water or the water fraction of the whey undergoes almost complete evaporation. The product inflates and adopts a texture which can be most closely compared with that of peanut puffs. The composition can be processed by means of a shaping die and subsequent cutting apparatus. Relative to starch-based extrudates, the products are distinguished in that they remain dimensionally stable after being placed in water. Optionally, an aftertreatment may be carried out on the products generated by the process described, in the form of further drying.

[0057] High Moisture Process

[0058] In the latter case, the mixtures are extruded in the presence of about 50 to about 75 wt % and more particularly about 55 to about 60 wt % of water and/or wheybased on the total amount of the raw materials used, i.e., the amount of components (a1+a2) and water and/or whey. The extrusion, again, takes place under pressure, which arises in particular from the parameters of rotary speed and temperature and is set at about 5 to 50 bar and more particularly about 10 to 30 bar. With this variant as well, the extrusion is carried out preferably in a twin-screw extruder which possesses corotating, shear-intensive screws.

[0059] The extrusion takes place, moreover, with application of a temperature gradient from likewise about 20 to about 200 C. and more particularly about 40 to about 170 C. In this case, necessarily, the temperature profile is not linear, but instead rises from the front to the middle part of the extruder to the highest temperature, before then decreasing again at the end. A regime of this kind may exhibit, for example, the following profile: increase from 20 to 40 C. to 160 to 200 C. (in the middle of the extruder) and drop (at the outlet of the extruder) to 100 to 140 C. A regime of this kind ensures particularly stable and uniform textures.

[0060] Since the products have a relatively high water proportion, the viscosity during processing is lower than in the case of the low moisture process. Depending on facility, the rotary speeds to be set are from about 200 to about 2000 rpm. Here again, the extrusion can be carried out, rather than with water, with whey or with a mixture of water and whey. The preferred ingredients in terms of the components (a1) dairy proteins here are whey proteins.

[0061] The nature of cooling, depressurization, and further processing may also influence the texture. In the simplest scenario, the products after leaving the extruder are depressurized in the air or in a cooling bath.

[0062] Preferably, however, after leaving the extruder, and with retention of the pressure, the mixtures are passed into a cooling tunnel, so that the cooled composition emerges under atmospheric pressure only in this way. A cooling tunnel is a simple component which consists, for example, of a pipe having a cooled outer jacket. The extruded composition is fed in at one end and departs the cooling tunnel at the other end, during which it is brought to ambient pressure. The cooling tunnel typically has a constant cross section over its entire length. The length and cross section of the cooling tunnel are dependent on the extruder size and on the resultant product throughput. The use of a cooling tunnel is a codeterminant in the construction of certain textures, since the conveying of the extrusion mixture through the pipe results in cooling from outside into the interior of the composition, thereby generating a particularly fibrous structure.

[0063] On emergence, the cooled composition still has a temperature of about 50 to 80 C. and is brought subsequently into piece form, by portioning the strand of texturized product using knives, for example. For further texturizing it is subsequently advisable to subject the compositions to at least one of the two following measures: [0064] (i) deep-freezing and thawing and/or [0065] (ii) cooking in stock.
Both measures serve to loosen the structure.

INDUSTRIAL APPLICABILITY

[0066] A further subject of the invention relates to the use of the texturized dairy proteins or of the corresponding method products as nutritional replacements, for meat, fish, vegetables, mushrooms or tofu, for example.

EXAMPLES

Examples 1 to 6Production of the Texturized Dairy Proteins (TDP)

General Production Protocol for Texturizing by the Low Moisture Process

[0067] A dry mixture containing dairy proteins (component a) and plant proteins and/or fibers (component b) was applied together with 22 to 33 wt % of water (based on the total mixture) to a twin-screw extruder consisting of 10 barrel units, where barrel units 2-10 were each individually heatable, whereas the first barrel unit could not be heated. Zones 1 to 3 served for feeding and mixing, zones 4 to 7 for a cooking procedure (protein melting and compression), and zones 8 to 10 for buildup of pressure. Depending on the facility, the raw materials used, and the recipe, the mixture was conveyed with a rotary speed in the range from 200 to 1500 rpm under a pressure set at from 40 to 110 bar.

General Production Protocol for Texturizing by the High Moisture Process

[0068] A dry mixture containing dairy proteins (component a) and plant proteins and/or fibers (component b) was applied together with 52 to 75 wt % of water and/or whey (based on the total mixture) to a twin-screw extruder consisting of 10 barrel units, where barrel units 2-10 were each individually heatable, whereas the first barrel unit could not be heated. Zones 1 to 3 served for feeding and mixing, zones 4 to 7 for a cooking procedure (protein melting and compression), and zones 8 to 10 for buildup of pressure and for initial cooling. Depending on the facility, the raw materials used, and the recipe, the mixture was conveyed with a rotary speed in the range from 400 to 1500 rpm under a pressure set at from 10 to 60 bar.

Further Processing of the Texturized Product Composition Obtained from the Low Moisture and High Moisture Processes [0069] (I) Immediate passage of the hot and plastic composition via a perforated plate (holes 4 mm in diameter) and rotating knives. During this procedure, the product underwent depressurization to ambient pressure, with the water evaporating apart from a slight residual moisture content. The throughput was around 50 kg/h. [0070] (II) Continuous passage from the extruder with a throughput of around 12 kg/h and depressurization to ambient pressure in a cooling bath. [0071] (III) Continuous passage from the extruder with a throughput of around 14 kg/h into a cooling tunnel and depressurization to ambient pressure. The extruded strand, with a temperature of 70 C., was portioned using knives and the portions, after cooling, were deep-frozen to 18 C.
In terms of texture and mouthfeel, the resulting products were reminiscent of the following original products:

A Chicken

[0072] B Dry meat (beef jerky)

C Tuna

D Tofu

[0073] E Peanut puffs

Make loaf shapes round and long by hand and place them each into a loaf tin greased with oil or baking spray. Treat the surface of the loaf with a dough docker and moisten them with a little water. Place the loaves in the proving oven for 50 minutes at a temperature of 35 C. and 80% relative humidity. Thereafter bake the loaves in a rack oven at a temperature of 180 C. for 60 minutes (preheat oven beforehand to a temperature of 240 C., set steaming for 1-2 minutes at start of baking). The core temperature of the loaves after the end of baking is 98 C. Remove the loaves from the tin after baking and allow to cool.
