Description

The invention relates to the dairy industry and can be used in the production of preventive products for the nutrition of people suffering from lactase deficiency and mild diabetes. A known method of producing cottage cheese paste, comprising introducing into the cottage cheese soft diet fat-free granulated sugar, cream of 15-25% fat, millet porridge, vanillin, the biologically active additive "Iodcasein", a filler, which is used as a syrup obtained from beetroot juice, mechanical processing of the mixture, pasteurization and cooling [Patent RU No. 2243574, A23C 23/00].

The disadvantage of this method is the use of ready-made cottage cheese as the main raw material; filler - a syrup obtained on the basis of beetroot juice, which can lead to a laxative effect, especially in children. Therefore, this product cannot be a preventive product for people with lactase deficiency and mild diabetes.

The closest in technical essence to the proposed method is a method for the production of curd paste “Angers”, which involves pasteurizing milk at a temperature of 90-95 ° C with holding for 2-3 hours, cooling to a temperature of 38-40 ° C, introducing a starter containing pure culture of lactic acid thermophilic streptococci and Bulgarian sticks in a ratio of 5: 1, ripening, pressing to a moisture content of not more than 80%, cooling, applying after cooling with stirring up to 5% sugar by weight of the clot [Patent RU No. 2277341, IPC А23С 23/00].

The disadvantage of this method is the lack of properties aimed at the prevention of lactase deficiency and diabetes; low content of vitamins and minerals necessary for the full development of the body. The technical result of the invention is expressed in obtaining a product with improved organoleptic properties by giving it a light nutty and strawberry aftertaste, in improving the quality of the finished product, its dietary and preventive properties, as well as improving digestibility, accelerating the process of fermentation and reducing energy value and accelerating the production process .

The technical result is achieved by the fact that the method for the production of whipped milk protein product includes pasteurization of milk at a temperature of 90-95 ° C, aging, cooling to a fermentation temperature, introducing fermentation, fermentation, pressing to a moisture content of not more than 80%, cooling, while milk they use fat content of 1.5%, in which, after cooling pasteurized milk to a temperature of 34-35 ° C, the Maxilact enzyme is introduced and fermented for 3 hours, then honey extract of germinated oat seeds and extract are added to the fermented milk germinated red beans, taken in a ratio of 2: 1 in an amount of 3-5% by weight of the product, the resulting mixture is pasteurized at a temperature of 72-74 ° C for 10-15 minutes, cooled to a fermentation temperature, pure cultures of mesophilic lactic acid are used as starter culture streptococci, Lactobactobacillus brevis BA-13 and lyophilized concentrate of bifidobacteria "BK-Altai-Lsbifi" in a ratio of 1: 1: 2 in the amount of 3-5% by weight of milk, before fermentation make feijoa juice with pulp in the amount of 5-7 wt.% , after pressing, biologically Ki active additives "Lactumin" and "Lactofit" in a ratio of 0.5: 1 in an amount of 0.5-1.5% by weight of the product, mix, thermalize, and after cooling, curd, beat, packaged with a temperature of 16-18 ° C and re-cool.

Examples of specific implementation of the method.

Example 1: Milk is purified, normalized to a fat content of 1.5%. Then, normalized milk is pasteurized at a temperature of 95 ° C, with exposure for 3 minutes and cooled to a fermentation temperature of 34 ° C and the Maxilact enzyme is introduced in an amount of 0.01% by weight of milk, kept in a thermostat for 3 hours. Into fermented milk, honey extract of oat seeds and sprouted red bean taken in a ratio of 2: 1 in the amount of 3% by weight of the product are introduced and the resulting mixture is pasteurized at 72 ° C for 15 minutes and cooled to the temperature of the milk, fermented no more 17 hours before the formation of a clot with an acidity of pH 4.5, pressed to a residual moisture content in the curd clot of not more than 80%, after pressing, the biologically active additives Lactumin and Lactofit are added to the resulting clot in a ratio of 1: 1 in an amount of 1% ofthe mass of the product is stirred, thermalization is carried out, and after cooling, the milk-protein product is whipped, packaged with a temperature of 18 ° C and further cooled for 2 hours to a temperature of 4 ± 2 ° C.

The resulting product has improved organoleptic properties due to giving it a light nutty aftertaste, increased quality, dietary, preventive properties and digestibility, as well as low energy value.

Example 2: Milk is purified, normalized to a fat content of 1.5%. Then, normalized milk is pasteurized at a temperature of 95 ° C, with exposure for 5 minutes and cooled to a fermentation temperature of 35 ° C and the Maxilact enzyme is introduced in an amount of 0.01% by weight of the milk, kept in a thermostat for 3 hours. An extract of germinated buckwheat seeds and an aqueous extract of thorns in a ratio of 2: 1 in an amount of 5% are added to the fermented milk, and the resulting mixture is pasteurized at a temperature of 74 ° C for 10 min and cooled to the fermentation temperature and the yeast prepared with sterilized milk with a fat content of 1 is introduced. 5%, of specially selected pure cultures of mesophilic lactic streptococci, bifidobacteria and Lactobactobacillus brevis BA-13 in a ratio of 1: 2: 1 in an amount of 5% by weight of milk, they are fermented for no more than 17 hours until a clot with an acidity of pH 4, 5, pressed to a residual moisture content in the curd clot of not more than 80%, after pressing, the biologically active additives Lactumin and Lactofit in the ratio 1: 1 in the amount of 1.5% by weight of the product are added to the obtained clot, mixed, thermalized, and after cooling, the milk-protein product is whipped and packaged with a temperature of 16 ° C, and further cooled for 3 hours to a temperature of 4 ± 2 ° C.

The resulting product has improved organoleptic properties due to giving it a light nutty aftertaste, increased quality, dietary, preventive properties and digestibility, as well as low energy value.

The introduction of the Maxilact enzyme as the enzyme responsible for the hydrolysis of lactose makes it possible to reduce the content of milk sugar in the milk base due to its action based on the breakdown of less soluble lactose into easily digestible monosaccharide - glucose and galactose. This leads to the prevention and diet therapy of lactase deficiency and mild diabetes. When introducing the Maxilact enzyme into the composition, less than 0.1 kg per 1000 kg of product allows to obtain a degree of hydrolysis of 75%, which is not enough to obtain a curd paste with a low content of milk sugar. The introduction of the enzyme "Maxilact" more than 0.2 kg is not advisable, since the degree of hydrolysis is close to 100%, which is not economically effective, as it turns out a product intended only for feeding people with lactase deficiency. At a fermentation temperature of 34-35 ° C for 3 hours, it is possible to reduce the amount of lactose in milk to 0.80%, which reduces the energy value of the finished product and increases the preventive, dietary properties of the product, its quality and digestibility.

Dietary supplements "Lactumin" and "Lactofit" in a ratio of 0.5: 1 in an amount of 0.5-1.5% by weight of the product have a preventive effect - they normalize carbohydrate metabolism, lower blood cholesterol, increase immunity, and replenish deficiency proteins, amino acids and vitamins (C, B1, B2, B6, B12, E, folic acid, biotin, niacin, pantothenate), strengthen musculoskeletal tissue. The introduction of honey extract of oat seeds germinated and extract of sprouted red beans and Lactumin and Lactofit dietary supplements in a ratio of 0.5: 1 in an amount of 0.5-1.5% allows to enrich the product with a vitamin-mineral complex and provide preventive and dietary properties for mild forms of diabetes, gastrointestinal diseases. Use as a starter culture - mesophilic lactic streptococci, consisting of special strains of streptococcus lactis, streptococcus cremoris, streptococcus diacetilactis, as well as Lactobactobacillus brevis BA-13 and lyophilized concentrate of bifidobacteria "BK-Altai-3: 1 in 1: 2 ratio: 1 -5% allows you to get a milk-protein product with a pronounced pleasant sour-milk taste with a light nutty and strawberry aftertaste, pasty consistency. The introduction of a starter culture of less than 3% is not enough to obtain a homogeneous sufficiently dense curd clot of a paste-like consistency. With the introduction of the starter culture in an amount of more than 5%, the curd clot has a pronounced grain-like consistency. Therefore, the introduction of starter culture in an amount of 3-5% is optimal for obtaining a homogeneous curd clot paste-like consistency.

The proposed method allows to obtain a product for the nutrition of people with lactase deficiency and mild diabetes mellitus, has moderate acidity, has high digestibility and biological value, high taste and extended preventive effect, as well as low energy value. Also, this method allows to enrich the diet with a vitamin-mineral complex and increase the body's resistance to negative environmental factors.
