FR 3025402 A1 20160311 FR 1501842 A 20150907 1 FIELD OF THE INVENTION This invention concerns an extended shelf-life proteinaceous meat analogue and the method for obtaining such extended shelf-life proteinaceous meat analogue. The invention also concerns a ready to eat proteinaceous meat analogue and the method for obtaining such ready to eat proteinaceous meat analogue. The invention further concerns a foodstuff comprising said extended shelf-life proteinaceous meat analogue or ready to eat proteinaceous meat analogue and the method for obtaining said foodstuff. BACKGROUND OF THE INVENTION Several types of wheat gluten-based meat analogues or wheat gluten based intermediates for preparing meat analogues have already been described in the state of the art. The best known wheat gluten-based meat analogue is "SEITAN". This is in fact a wheat gluten dough which is seasoned. This dough is then cooked to provide the "wheat meat". Before final processing, SEITAN must be stored cold, or in frozen conditions, because of its high moisture content (>50% moisture). Apart from SEITAN, also other wheat protein based meat replacers have been described in the prior art. However, it has been observed that the products of the prior art, if used as meat analogues or meat extenders, do show a number of shortcomings with regard to texture, storage stability and/or ease of processing. This might explain the relatively limited success of such products in the market. Among those products from the prior art texturized meat analogues can be mentioned, such products are obtained by an extrusion step at high temperature (more than 120°C), those products are usually named high moisture texturized proteins (HMTP) or low moisture texturized proteins (LMTP). The methods for obtaining LMTP are for example disclosed in US5922392, GB1288193, US3769029 or W02012/008994 and provide products having spongy texture and which cannot be shaped easily without using binders such as eggs. The HMTP are difficult to manufacture and may have a mushy consistency if expansion directly after the extrusion at high temperature. Usually, a cooling die is used at the end of the 3025402 2 extrusion in order to avoid any expansion of the product. However, such cooling die is regularly clogged, thereby varying pressure within the barrel of the extruder and resulting in an unpredictable efflux of the product from the die as mentioned in US 20100136201. Moreover, an incorrect orientation of fibers in the product may take 5 place inducing additional treatment of the product to re-orientate the fibers. Such treatment leads to complex and costly installations. A simple and cheap process providing a proteinaceous meat analogue having a good texture is needed. Besides, the applicant has developed a low moisture plasticized wheat gluten composition (W02007006431). However, this composition is only suitable for 10 use in chewy pet food applications, because of its high breaking force. Prior art also described meat analogues obtained by agglomerating protein filaments or protein fibers by using a binder such as albumin notably by making an emulsion then coagulating the emulsion obtained, such process is disclosed in GB977238. Such protein filaments or protein fibers are obtained by spinning 15 process, which consists in the precipitation of a protein solution to form stretched fibers. However, spinning produces large waste water streams. In addition, the necessity for low pH, high sait concentrations and chemical additives makes the process very complex to implement (Manski et al., 2007). Therefore the goal of this invention is to provide proteinaceous meat 20 analogues showing improved meat-like properties with regard to texture, chewiness and bite, compared to aiready existing products, but also to provide proteinaceous meat analogues which can be shaped easily without adding any binder so as to form big pieces of meat analogues with irregular shapes such as natural pieces of meat but also so as to include easily food pieces (vegetables..) to provide a foodstuff 25 having a good nutritional intake. At the same time it is the purpose of this invention to provide storage stable intermediates, which after hydration, provide easily ready to eat meat analogues showing a feeling in mouth which is as close as possible to meat without any additional treatment. Further, the invention provides processes for preparing these proteinaceous meat analogues and their storage-stable 30 intermediates. DESCRIPTION OF THE INVENTION 3025402 3 Extended shelf-life proteinaceous meat analogue and the method for obtaining such extended sheif-life proteinaceous meat analogue The invention is about a method for obtaining an extended shelf-life proteinaceous meat analogue comprising the step of: 5 - mixing at a temperature of less than 100°C i) vegetable proteins among which at least vital wheat gluten (VWG), ii) a plasticizer and optionally iii) fibers for obtaining a dough, - optionally shaping said dough, preferably by cutting, sheeting, agglomerating and/or molding, 10 - heating preferably static heating between 120 to 160°C during 1 minute to 1 hour of said dough for obtaining an extended shelf-life proteinaceous meat analogue wherein said extended shelf-life proteinaceous meat analogue has a water content of Iess than 20% (w/w) and preferably, wherein said plasticizer is selected 15 among a polyhydroxy alcohol, a starch hydrolysate, a carboxylic acid and mixture thereof. Typically, the mixing step may be implemented by any mixing device capable of handling high viscosity materials (such as z blenders, ribbon mixers, planetary mixers or co rotating intermeshing extruders). Advantageously, the mixing 20 step is carried out in a batch or a continuous mixing unit, preferably at a temperature of Iess than 100°C (such as between 20 to 90°C, preferably, 30 to 65°C more preferably 40 to 50°C) for a period sufficient to obtain a dough-like composition. Typically, the mixing step is an extrusion step. According to the invention, an "extrusion" refers to a process in which a 25 material is pushed under compressive stresses through a deformation control element such as a die to form an elongated product. Continuous extrusion refers to an extrusion process where such deformation is carried out on a product of unlimited length. Advantageously, the extrusion according to the invention is implemented at a temperature of less than 100°C, such as between 20 to 90°C, 30 preferably, 30 to 65°C more preferably 40 to 50°C. lndeed, the inventors have shown that a mixing step at a temperature above 100°C notably by extrusion at 3025402 4 temperature above 100°C provides a product having spongy texture which is not observed for the product of the invention. Advantageously, a food product, a food additive and/or a processed food may be added during the mixing step. Such food product, food additive and/or 5 processed food may be in a dried form or a hydrated form, typically by having a water content of more than 50%. As used herein "processed food" refers to a food which is significantly modified from its natural state, as by mechanical alteration (such as grinding or chopping), combination with other food products or additives, and/or cooking. As 10 used herein, "processed food" excludes foods which substantially maintain their natural state after processing. For example, fresh produce may be washed, sorted, coated or treated, and packaged, but remain substantially in its natural state after processing, and would not be considered a "processed food" for the purpose of this disclosure. A "processed food" also refers to an extract of food. The "extract" refers 15 to the resultant solid or liquid material from an extraction. Indeed, an extract obtained from animal origins (such as meat or fish) or vegetal origins, such extract may be soluble or insoluble carbohydrates, proteins, fibers, fat, or combinations thereof. The processed food may comprise oil or fat particles, and particularly preferred is vegetable oil or fat, especially that used in the form of sunflower oil. The 20 processed food may also comprise particles of an inorganic sait. Calcium or magnesium salts are preferred. The processed food may comprise an insoluble material, for example an insoluble organic or inorganic sait. As used herein "food products" refers to pieces of meat or fish or vegetables such as for example nuts, cereals, carrots, leguminous. 25 As used herein "food additives" preferably includes simulated meat flavorings such as pork flavor, pepperoni flavor, smoke powder, chicken flavor, beef flavor, seafood flavor, savory flavorings (e.g., onion, garlic), vitamins (such as vitamins B12) and mixtures thereof. According to the invention, said dough obtained by mixing of vegetable 30 proteins and at least one plasticizer can further be shaped before the static heating. The shaping step according to the invention comprises at least one or a combination of cutting, molding, sheeting and aggiomerating steps. Preferably, the 3025402 5 shaping step comprises at least a cutting step and a molding or a sheeting step, more preferably a cutting step, a sheeting step and a molding step. According to an embodiment, the shaping step comprises a cutting step, an agglomerating step and optionally a molding and/or a sheeting step. 5 The cutting step may be done by using any means having at least one blade, for example a meat mincer (mincing machine), or a meat cutter. Advantageously, the shaping step comprises at least cutting the dough in dough pieces and agglomerating the dough pieces by hydrating and by mixing the dough pieces to obtain an agglomerate having a water content between 5 to 30%, 10 preferably 7-25%, more preferably 10-20%. According to the invention, the dough piece has a mass of at least 0.03g preferably 0.04 to 300g more preferably 0.05 to 30g, 0.05g to 3g typically 0.05g to 0.2 g. Advantageously, said dough piece may have a long or a circular shape. The sheeting step may be implemented by compressing dough pieces 15 between cylindrical rolls The molding step may be implemented by compressing dough pieces into molds of any desired shape. The method of the invention is particularly advantageous in that without any added binder, the product develops a very good agglomerating and molding 20 properties providing big pieces of meat analogues having very high volume. Moreover, the texture of the product obtained is dense enough to provide a uniform piece of meat analogue. Examples of size and texture which can be provided is the one of an escalope or a wiener schnitzel. Such pieces cannot be obtained by using the meat analogues of the prior art without adding a binder such as eggs or xanthan 25 or starch providing a product which cannot be eaten by vegan people or having poor texture. Moreover, the meat analogue according to the invention is particularly easy to mold and provides structure having irregular forms close to natural meat steaks or beefsteaks. Besides, the shaping steps such as the cutting, agglomerating, sheeting 30 and molding steps can be repeated in order to obtain a product having a fibrillar structure which can be close to the myofril structure of skeletal muscles. Typically, a 3025402 6 very nice fibrillar structure can be obtained when the dough pieces are of longitudinal shape. As used herein the term "static heating" refers to a heating step without any stirring or shearing of the dough to be heated. An example of static heating may be 5 oil frying, microwaving, or by using an oven, or a hot plate. Typically, the heating step is carried out at a temperature between 120 to 160°C during 1 minute to 1 hour, typically, 10min to 30mn. The duration of the heating step can be adapted by the man skilled in the art depending on the volume of mixed proteins to be heated. The inventors have shown that boiling (100°C) or an heating at 110°C of the mix of 10 vegetable proteins and plasticizer does not provide the meat analogue of the invention. Moreover, an heating step above 160°C for example a classical frying step (at 185°C) provides a product which has a very soft and spongy texture and a dark color. It should be emphasized that meat analogues in accordance with the present 15 invention may be used as meat replacements to provide a meatless foodstuff or as meat enhancers/extenders to replace a portion of the meat that would normally be present in a foodstuff As used herein an extended shelf-life product is a product which is shelfstable at ambient temperatures for an extended period of time for e.g. up to and 20 above 60 days. Such extended shelf-life product is microbiologically stable because of its reduced water content. Such an extended shelf-life product may be eaten after hydration and cooking. Such extended shelf life product may be a petfood, typically designated to cats and dogs. As used herein the term "vital wheat gluten" refers to those forms of dried 25 wheat gluten that have been subjected to only minimal or no heat denaturation during drying. Upon reconstitution with water, vital wheat gluten shows physical properties (e.g., elasticity, gumminess, etc.) similar to those of freshly prepared wet wheat gluten. Preferably, the vegetable proteins are powdered vegetable proteins (as 30 measured according to AOAC 979.09; Kjeldahl method with a conversion factor N*6,25). Advantageously, said vegetable protein powder has a water content of between 1 to 15% preferably 2 to 12%, typically, 3 to 7%. Said vegetable proteins may be vital wheat gluten (100% of vital wheat gluten) advantageously a vital wheat 3025402 7 gluten powder. Typically, said vegetable proteins are a mixture of vital wheat gluten and vegetable proteins from at least one other origin. According to one embodiment, vegetable proteins comprise more than 50% of vital wheat gluten, preferably, more then 60, 70, 80, 85, 95% of vital wheat gluten. Preferably, the "vegetable proteins 5 from at least one other origin" or "vegetable protein other than VWG" may be selected from a group consisting of potato, lupine, soya, pea, chick pea plants, alfalfa, faba bean, lentil, bean, rapeseed, sunflower and cereals such as corn, barley, malt and oats. Said vegetable proteins are typically in the form of flour, concentrate or isolate. 10 Vital wheat gluten or VWG refers to the dried, insoluble gluten portion of wheat flour from which the starch and soluble components have been removed by a washing process. Typically, vital wheat gluten is then dried to a fine powdered state. Vital wheat gluten powder typically has a percent protein on a dry basis of about 80% or greater (as measured according to AOAC 979.09; Kjeldahl method with a 15 conversion factor N*6,25). Vital wheat gluten is typically not denatured as determined by the test procedure in "Approved Methods of the American Association of Cereal Chemist", Method 38 entitled "Vital Wheat Gluten" (December 1962). Useful vital wheat gluten powder is commercially available under the trade designation AMYGLUTEN®. 20 As used herein, a "plasticizer" refers to a compound that increases the plasticity or fluidity of the material to which it is added. Typically, the plasticizer of the invention is a "food grade plasticizer" which is a plasticizer approved to be used in foods. Advantageously, the plasticizer is a non-aqueous plasticizer, typically said plasticizer has a water content of less than 20% (w/w). Advantageously the 25 plasticizer may be a polyhydroxy alcohol (such as glycerol, sorbitol, ethylene glycol, polyethylene glycol propyleneglycol, butanediol, polyethylenglycol and mixture thereof), a starch hydrolysate (such as a glucose syrup), a carboxylic acid and mixture thereof. As used herein, "fibers" may be insoluble fibers, preferably from cereal, 30 tuber, seed or leguminosae. The term "water content" refers to the content of water based upon the Loss on Drying method as described in Pharmacopeial Forum, Vol. 24, No. 1, page 5438 3025402 8 (January-Feburary 1998). The calculation of water content is based upon the percent of weight that is lost by drying.

The inventors have shown that the characteristic which is important to be a good meat analogue is to give the feeling of meat during mastication. The inventors have shown that to the opposite of the meat 5 analogues of the market such as for example, the low moisture texturized proteins, the meat analogue of the invention gives a feeling which is very close to meat due to its physicochemical characteristics. The feeling during the first bite (30 sec) than after several mastications (10min) can be evaluated by the ratio torque value at 30sec/ torque value at 10min. 10 The invention is further about an extended shelf-life proteinaceous meat analogue comprising vegetable proteins among which at least wheat gluten, notably VWG such as for example VWG powder and a plasticizer said proteinaceous meat analogue having a water content of less than 20% (w/w) and a torque value at 10mn of at least 10 gram meter (g*m) (preferably between 10 and 15 30, more preferably between 12 to 25), or a ratio torque value at 30sec/ torque value at 10mn of about 1 to 1.5, as determined by a test A, preferably said proteinaceous meat analogue also comprises fibers.

The invention will be further evaluated in view of the following examples and 30 figures. 3025402 14 BRIEF DESCRIPTION OF THE FIGURES Figure 1. Comparison of torque values between commercial products and product according to the invention (P3 6% fibers) EXAMPLES 5 Example 1: Preparation of wheat gluten based products of the invention Vital wheat gluten powder (AMYGLUTEN®) (75 parts), glycerol (100%)(25 parts) and wheat fibre (VITACELL® 400) (0, 3 or 6 parts) are continuously mixed 10 together in a twin screw extruder (Werner & Pfleiderer ZSK25) at a temperature of 65°C, and shaped and cut to obtain small particles with a ZGF30 pelletizer (Werner & Pfleiderer). These particles can then be stored at room temperature, without risk of spoilage. Three different kinds of products (A1, A2, and A3) are obtained, having a different content of fibres (0, 3 and 6%). 15 Agglomerates of these particles are prepared by spraying 3 parts of water over the particles, and manually pressing the hydrated particles together into a mould having the shape of a pork chop. The agglomerates obtained are then fried in cooking oil at 150°C for 5 minutes, thereby providing products P1, P2 and P3. Example 2: Chewing and bite properties of meat analogues, and 20 meat products: The products prepared in example 1 were hydrated and then cooked in boiling water for 20 minutes, resulting in products containing 60-65% water (35-40% dry substance). Products differed in fibre content whereby P1 contained 0% fibre, P2 contained 3% fibre and P3 contained 6% fibre on dry substance. 25 The texture analysis was made in a Brabender Plastograph, type EC equipped with a type 50 measuring head and a mixing chamber comprising two counter-rotating identical sigma shaped mixing blades (references of the blades: Sigma (S)). 70g of cube shaped samples (151 5mm) are introduced in the mixing chamber thermo-stated at 37°C and measurement is obtained by counter-rotating 30 the mixing blades at differential speeds of 34rpm and 22.67rpm (34*2/3). 3025402 15 The torque values were recorded and compared with cooked meat products such as cooked beef, cooked chicken and cooked schnitzel. Also torque values for meat analogues available in commerce, such as SEITAN, and commercial products such as "VIANA" cowgirl veggie steak, and "TOPAZ" Wheaty Vegankebab Miner 5 were compared with the products of the invention. Ail these products were also cooked in boiling water for 20 minutes. In the following table, torque values are given after 30 seconds, 10 minutes and 14 minutes for all the above cited products. Torque (g*m) after 30 sec 10 min 14 min Cooked beef 70 35 32 Cooked chicken 30 20 18 Cooked schnitzel 13 13 11 Comm. Product 1 13 7 7 Comm. Product 2 15 8 7 Seitan 10 5 5 P1 13 12 10 P2 14 13 13 P3 17 14 13 10 Table 1: Comparative analysis of torque values of meat pieces (beef, chicken, schnitzel) and meat analogues of the market (SEITAN, TOPAZ, VIANA) and of the invention at 30sec, 10min and 14min. A sensorial evaluation of the cooked pieces has been done in order to evaluate their textural properties compared with the measured values: 15 - Cooked beef is experienced as quite hard in bite (as expected for a beef cooked for 20 min in water). This observation is confirmed by the torque results which are very high at 30 sec, a siight reduction is observed at 10 and 14mn, - Cooked chicken is experienced softer in bite than beef but still on the 20 hard side. The torque values show quite constant results confirming the sensory evaluation. - Cooked schnitzel is experienced as having a nice texture in a wellbalanced equilibrium between hardness and softness of the texture 3025402 16 - The commercial products 1 and 2 were good in the first bite but lost structure very soon after the first bite and got too soft, the commercial products 1 and 2 shows a ratio torque value at 30 sec / torque value at 10mn of 1.9 which indicate a quick loss of texture in the mouth. 5 - Commercial SEITAN product was too soft from the very first bite, all the torque values of SEITAN are below 10g*m, which seems to be too soft for a tasty meat analogue. The examples of the invention (P1, P2 and P3) were considered as very nice in the first bite and also maintained a good texture during chewing. 10 The results clearly show that measured torque values correspond well to the experience of eating the test pieces. Indeed, it is clear that the products of the invention do show much better chewing and bite properties than actually commercialised wheat gluten based meat analogues. At the same time these values illustrate that the products of the invention 15 approach chewing and bite properties of natural meat products. Example 3: Vital wheat gluten powder (AMYTEX®)(50 parts), glycerol (100%)(33 parts), chick pea flour (13 parts) and wheat fibre (VITACEL® WF200) (4 parts) are continuously mixed together in a twin screw extruder (Werner & Pfleiderer ZSK25) 20 at a temperature of 65°C, and shaped and cut to obtain small particles with a ZGF30 pelletizer (Werner & Pfleiderer), thereby providing product A4. These particles can then be stored at room temperature, without risk of spoilage. Agglomerates of these particles are prepared by spraying 11 parts of water over the particles, and manually pressing the hydrated particles together into a 25 mould of 15 mm thickness, thereby providing product W4. The product is then fried in cooking oil at 150°C for 10 minutes, thereby providing the product P4, and hydrated for 48 hours in water, resulting in products containing 60-65% water (3540% dry substance). This product is prepared and analyzed with the Plastograph as described in example 2. 30 3025402 17 Torque (g*m) 30 sec 10 min 14 min after P4 16 10 10 Table 2: Analysis of torque value of the product of the invention at 30 sec, 10min and 14min. The nutritional content of the meat analogue of the invention was calculated 5 and then compared to the ones of the meat analogue of the market (see table 3) By comparing the product of the invention to the ones of the market based on wheat, pea or soy proteins, it can be seen that the product of the invention has a very low content in lipids but a high content in fibers, proteins and carbohydrates giving to this product a very nice nutritional profile. 10 Overall composition Moisture Proteins Fibres Fat Salt Carbo hydrat es g/100g Sugar s Gross Energ y KJ/10 Og g/100g g/100g g/100 g g/100 g g/100g g/100g Ready- to-eat product of invention P4 (calculated) 65,0 22,4 3,8 2,0 0,2 6,5 0,7 594,0 Wheat protein Seitan medaillons 55,5 31,4 6,6 2,1 4,1 0,3 869,0 based DAS Schnitzel 51,6 25,1 9,4 2,5 9,2 2,2 969,0 products Frankenberger 53,1 25,6 12,0 1,4 6,2 1,7 981,0 Weenies 49,0 30,6 14,6 1,7 3,7 0,4 1123,0 Kebab gyros 53,7 26,4 12,4 2,5 3,5 1,5 993,0 Soy or Beefy crumble 63,6 23,6 1,8 9,1 1,2 1,8 1,8 837,4 pea protein Feisty crumble crumble 63,6 23,6 1,8 9,1 1,2 1,8 1,8 837,4 products grlled strips 68,2 23,5 1,2 5,9 0,8 1,2 1,2 591,1 lightly 65,9 23,5 2,4 3,5 0,8 4,7 0,0 591,1 seasoned strips Beast Burger 59,3 20,4 3,5 14,2 0,8 2,7 0,0 963,3 Tofu Natur 70,6 16,9 1,5 9,9 0,0 0,4 0,7 684,0 Bjorg Table 3: Nutritional analysis of the soy, pea, or wheat based meat analogues of the market and the one of the invention 3025402 18 Example 4 : Different cooking conditions The product W4 from example 3 is cut in pieces of 20 x 20 mm and cooked in several conditions. The pieces are fried for 15 min either at 110°C or at 150°C or at 185°C. The pieces 5 are cooked in an oven at 150°C either for 15 min or for 30 min. The pieces are cooked in boiling water (100°C) for 15 min. Ail these cooked products are then hydrated for 48 hours in water and tasted after cooking in a pan for 5 minutes. The products cooked at 150°C (in the oven or in the fryer) were good in texture and have a nice yellow to light brown color. 10 The product cooked at 185°C is very dark (brownish, nearly black). Moreover, this product was found more spongy and softer in texture than products cooked at 150°C. The products fried at 110°C or boiled at 100°C are found very white in appearance, so not attractive for a consumer and their texture was much softer than products 15 cooked at 150°C. Example 5: Vegan Wiener schnitzel Agglomerates of the product A4 from example 3 are prepared by spraying 11 parts of water over the product A4. Then, the agglomerates are grinded continuously through a Hobart meat grinder attachment (Hobart A200N, plate of #12 1/8"), 20 thereby providing multiples strands. These multiples strands are cut in portions of 100 mm length. Each portion is passed through a manual dough sheeter set with a thickness between the steel cylinders of 1 to 3 mm in order to form a schnitzel having dimensions of up to about 300 mm in diameter and of 4 to 7 mm in thickness. 25 The product is then fried in cooking oil at 150°C for 15 minutes and hydrated for 48 hours in a vegetable broth (one vegetable bouillon cube of 11 g for 500 mL of water). This product is then rolled in a mix of flour, yeast flakes, sait and water. Then, it is rolled in bread crumbs and fried at 170°C for 5 minutes or cooked in a pan for 5 30 minutes in order to prepare a vegan Wiener schnitzel. The obtained Wiener Schnitzel is very nice in taste, texture and appearance. It has a crusty crumb with a firm but still tender bite. 3025402 19 Example 6 : Product of invention in a complete dish Agglomerates of the product A4 from example 3 are prepared by spraying 11 parts of water over the product A4. Then, the agglomerates are grinded continuously through a Hobart meat grinder attachment (Hobart A200N, plate of #12 1/8"), 5 thereby providing multiples strands. These multiples strands are passed continuously through a manual dough sheeter set with a thickness between the steel cylinders of 5 mm, thereby providing a continuous strip of 15 mm thickness and 150 mm width. Pieces of 15 mm x 30 mm are cut from this strip. 10 These pieces are then fried in cooking oil at 150°C for 15 minutes and hydrated for 48 hours in a vegetable broth (one vegetable bouillon cube of 11 g for 500 mL of water). The hydrated pieces (1280 g) were cooked with: 80 g of Chinese dried black mushrooms (hydrated in excess of warm tap 15 water) 1,6L of Coconut milk 0,8L of Coconut cream 150 g of Ginger (minced in SEB Optimo cutter) 100g of Lemon Grass (cut in pieces) 20 50 g green curry 50 g Basil (cut in fine pieces) 50 g of Soy sauce 2 g dried lime grass 100 mL of sunflower oil 25 The whole recipe was cooked on gentle heat and stirred for 30 min. Upon stirring and heating, pieces remain entire without any disintegration. The whole dish is very attractive in appearance and taste. Example 7: Sausages containing carrots, parsnips and Ieek 600 g of product A4 from example 3 are mixed with 150 g of leek, 125 g of 30 carrots and 125g of parsnips in a Stephan cutter (UM 12 V Type). The mixture is then formed into sausages with a Bomann meat grinder (FW 443 CB Type) equipped with a sausage filling funnel and cellulose casings (Viscofan, composed of 3025402 20 65% regenerated cellulose, 18% glycerine, 15 % eau and 2% oil). After removing the casings, the sausages are cooked in a Miele steam oven at 121°C for 15 min, hydrated for 48 h and grilled in a pan. The obtained sausages have an attractive texture and color. 5 Example 8: Vegan meat balls 740 g of product A4 from example 3 are mixed with 150 g cashew nuts, 100 g of water and 10g of sait in a Stephan cutter (UM 12 V Type). The mixture is then formed through a Bomann meat grinder (FW 443 CB Type) and a very cohesive vegetable minced meat is obtained. The minced meat is formed by hand into "meat" 10 balls The so formed meat balls are fried in oil at 150°C for 15 min, hydrated thereafter in excess water and cooked in a pan. The obtained meat balls have an attractive taste, texture and appearance. Example 9: Vegan hamburgers 690 g of product A4 from example 3 are mixed with 300 g of carrots and 10g 15 of sait in a Stephan cutter (UM 12 V Type). The mixture is then formed into hamburgers using a Bomann meat grinder (FW 443 CB Type) and a hamburger shape. The so formed hamburgers are fried in oil at 150°C for 15 min, hydrated thereafter in excess water and cooked in a pan. The obtained hamburgers have an attractive taste, texture and appearance. The carrot pieces can stil) be distinguished 20 in the product and are very strongly embedded in the vegetable protein matrix. REVENDICATIONS1.
