FIELD: food industry. SUBSTANCE: invention relates to food industry. According to the proposed method, a granulation mixture is prepared; for this purpose, a solution of sodium alginate and a thermotropic polysaccharide is prepared based on a liquid food product whereto a marginally soluble calcium salt is added. Resultant is a granulation mixture represented by a suspension of the calcium salt in the polysaccharides solution that is extruded into the forming medium at a temperature exceeding that of the thermotropic polysaccharide gelatination. The forming medium is represented by a solution based on soluble calcium salts. After extrusion, primary granule shells are formed that are relocated from the forming medium into the affixing medium which results in formed grounds generation. EFFECT: proposed method enables production of a granulated food product from liquid food products such as juice, puree, kvass, wine, cider, balsams, flower infusions and cocktails. 5 cl, 1 tbl, 14 ex
The technical field The invention relates to methods of obtaining granulated food product, such as granulated material for food and products in the form of fillings for ice-cream, creams, sweet mass, pudding, jelly, souffle. Prior art A prerequisite for the claimed invention is the absence to date of ways to get food granulated product of liquid food products such as fruit and vegetable raw materials, balms, tinctures of flowers, cocktails, etc., preserving organoleptic characteristics, peculiar to fresh liquid food products, fruits, fruits, berries and vegetables. The developed method of production of eggs using pectin [1]. In this way we obtain a formula for granulirovanija by mixing at a temperature of 55...60 degrees With an aqueous solution of beet pectin (7...10%) and aqueous solution of gelatin (3...4%). The mixture drops ekstragiruyut in vegetable oil, cooled to a temperature of 5...10°N Next granules are treated water tea extract, which contains 0,1...1% tannins and 0.1...1% calcium chloride, for 20...30 minutes. The processing is carried out during 2...5 minutes and in aqueous solution of ferric chloride at a temperature of 5...10°N The pellets washed with water, separated from the water by centrifugation and implement culinary processing to provide the product with specific taste and aroma. Also known method of production of similar natural granular caviar [2], in which mussel soup, obtained by blanching mussels, boiled until the dry matter content of 10...20%. A chilled soup mixed with gelatin, sodium Caseinate, vegetable refined deodorized oil, add pasty colour, obtained by separation of tea extract ferric chloride. Mix carefully mix, heated to a temperature of 45...50 C and filtered. From this mixture into pellets imitated caviar in the environment of vegetable oil at a temperature of 6...10°N Shaped granules are separated from the oil, washed with water, treat 0.2% solution of pectin and 0.25% solution of calcium acetate. Then hold culinary processing of granules in protein-oil emulsion, which consists of mussel soup and vitamin-oil mixture. Also known method of production of caviar black granular from natural products "Phyto PL" [3]. This method differs in that gelatin, soaked with milk whey, agar, sodium alginate or pectin. Formed in oil granules are treated so-called "cocktail". The composition of cocktails enter vitamins, antioxidants, selenium, ciankobalamin, beta-carotene, fish oil, as well as extracts on the basis of krill. Soak gelatin and polysaccharides of algae carried out in solutions of medicinal plants (root quack grass, succession, nettle, immortelle, burdock root, strawberry leaves). There is a method of obtaining an analogue of caviar [4]was chosen as a prototype, which is that of a mixture, which consists of ionotropic geleobrazovaniju (pectin, sodium alginate or their mixture), table salt, as well as isolated soybean protein, extruded into pellets 5% cooled to a temperature of 0...8 degrees of the solution of calcium chloride for 10 minutes. After laundering granules pasteurized at the temperature of 60 C and treated with flavoring emulsion. The product is a solid gel granules, imitating to taste caviar fish, however, by structural-mechanical characteristics significantly different from her. The disadvantage of the prototype is the inability to control the structure of granulated product, hence its organoleptic properties, because you cannot control of diffusion processes, so the product is obtained unstable and diverse quality. At the same time these products have low water-holding capacity, typical of the gels of calcium alginate, which lowers the organoleptic characteristics of the final product. These shortcomings can be addressed by the implementation of the present invention. The essence of the invention The aim of the invention is to obtain food granulated product of liquid food products such as juice, puree, kvass, wine, cider, balms, tinctures of flowers, cocktails, etc. As well as liquid food can use a liquid Foundation product such as juice component of fruit and vegetable puree. Also the aim of the invention is development of methods of processing of fruit and vegetable raw materials in the food granulated product preserving organoleptic and structural-mechanical properties, peculiar to fresh fruits and vegetables. Other tasks and advantages of the invention will be described below as the presentation of the present description. The proposed invention provides the ability to get food granular products, imitating organoleptic and structural-mechanical properties of fruits, berries and vegetables. Obtained granulated food products have a spherical shape with a diameter of 0,1...1,0 cm, consistency from elastic to hard and brittle, with taste and aroma typical of the selected for the granulation of the product. In structure of food granulated product is a granule, i.e. uniform structure. Essentially the aim of the method is achieved as follows. Cook the mixture for granulating, for which the solution of sodium alginate necessary concentration mixed with poorly soluble salt - source of calcium, under these conditions, the interaction and the emergence of ionotropic gel is impossible. Simultaneously to this mixture thermotropic polysaccharide, for example: carrageenan, agar, pectin or their mixtures, as the dry fraction, with a ratio of sodium alginate, thermotropic polysaccharide and less soluble salts calcium(5÷100):(5÷100):(1÷6). Translate thermotropic polysaccharide in dissolved state by heating a mixture of sodium alginate and carrageenan to temperatures above the temperature of dissolution of thermotropic polysaccharide. So, get mixture for granulation in the form of two-component system "colloidal solution of sodium alginate and thermotropic polysaccharide - soluble salt of calcium. On colloid state of the mixture for granulating is a suspension of low-soluble salts in colloidal solution of sodium alginate and thermotropic polysaccharide), in which the proportion of dry substances in liquid basis, respectively)(1,1÷20,6):(98,9÷79,4). If necessary, in the mix for granulating add flavorings, protein, fat-containing substances, vitamins, dyes, or their mixture. Simultaneously prepare shaping environment - solution on the basis of soluble salts calcium, for example: the solution of calcium chloride, calcium lactate in the water and prepare an adapter environment - acid solution (for example, lemon, Apple, acetic acid, grape acids or their mixtures) with a concentration of 0,1...0,6%. During extrusion of mixtures for granulation in shaping the environment at temperatures above the temperature of gelation thermotropic polysaccharide produced primary shell granules by surface appearance of sodium alginate. Formed pseudogroup separated from forming environment and cool. While the full replacement of sodium calcium alginate (mixture for pelletising) not occur, and thermotropic polysaccharide (carrageenan) by cooling creates thermotropic gel. After that formed pseudogroup with the primary shell move in a secured environment (for example, citric acid solution) with a concentration of 0,1...0,6% and stand in it 30...180 minutes. Acid diffuses into granules, while soluble soluble salt of calcium released calcium ions interact with sodium alginate, forming ionotropic gel alginate calcium. Creates a pellet with well-controlled properties, as the ratio of low-soluble calcium salt to sodium alginate controlled and justified. After the separation of granules from an adapter among them washed under running water. Thus, there is a pellet with mixed gel ionotropic due to the interaction of sodium alginate calcium ions, obtained after the dissolution of soluble salts of calcium, and thermotropic due thermotropic polysaccharide. At the same time, the density of these Galiev is out of control that provides control For realization of the invention provides for the existence of three liquid water environments: - mixture for granulating containing a two-component system "colloidal solution of sodium alginate and thermotropic polysaccharide - soluble salt of calcium", with a ratio of sodium alginate, thermotropic polysaccharide and less soluble salts(5÷100):(5÷100):(1÷6) respectively. If necessary, in the mix for granulating can be added vkusoaromaticheskiye substances, protein, fat-containing substances, vitamins, dyes and other; - forming environment - solution on the basis of soluble salts calcium; - adapter environment - solution acids (citric, malic, acetic acid, grape acids or their mixtures) with a concentration of 0,1...0,6%. It should be noted that the use of the claimed invention receive granules, containing ionotropic gel on the basis of sodium alginate and thermotropic gel on the basis of thermotropic polysaccharide. This ionotropic part of gelation and poorly soluble salt of calcium allow clearly to control the content of calcium granules, and thus the structural-mechanical properties of granulated product consistency, which is also an advantage of the claimed invention. Thermotropic part of gelation allows to increase the water-holding capacity and create consistency granulated product is acceptable to the consumer, which is also an advantage of the claimed invention. An important condition of extrusion process mixtures for granulation is the temperature of the dissolution of thermotropic polysaccharides, which is in the range of 80...85 degrees, as well as extrusion at temperatures above the temperature of fermentation of thermotropic polisaharidov, which is in the range from 40 to 95 C, which is due to the point of gelation thermotropic polysaccharides.
