Description

The invention relates to the dairy industry, in particular to a technology for the production of milk-containing products with a high concentration of lactose - more than 11%.

For the successful implementation of the process of crystallization of lactose and the production of high-quality products at the dairy enterprises, such technological methods as intensive cooling and seeding are used. As a seed, fine-grained refined milk sugar (lactose), special lactose preparations, supersaturated solutions of lactose with crystal nuclei, and water-soluble high-molecular organic substances in a crystalline state mixed with lactose can be used. The seed is introduced at a certain point in the technology and at a certain temperature, that is, by various methods, determining the temperature of the enhanced mass crystallization of lactose, for example, according to the schedule of K. Hudson.

Closest to the claimed is a method for the production of condensed milk with sugar according to TU 9226-353-00419785-03, which provides for the normalization of the initial milk-containing raw materials, pasteurization, cooling to 32-37 ° C, seeding, crystallization, packaging.

The disadvantages of the method are: the lack of a guarantee of obtaining the required crystal sizes, the need for seeding at a specific temperature and time, the need for pre-treatment of the seed material (drying and grinding).

The technical result is to simplify the crystallization process through the use of water-insoluble finely dispersed substances 1-3 microns in size and to obtain a product of stable quality during storage.

The technical result is achieved in that a method for producing dairy products, including normalization of the initial milk-containing raw materials, pasteurization, cooling, seeding, crystallization and packaging, is characterized in that as a seed, a water-insoluble finely dispersed substance with a particle size of 1-3 microns or a mixture of insoluble finely crystalline substances in water in an amount of not more than 5.0 kg per 1 ton of product, which are added in one go or in portions from 0.01-0.49% by weight of the finished product before normalizing sludge at any stage of the process.

A confirmation of the effect is the very essence of the process of lactose crystallization, which consists in the mass formation of nuclei of lactose crystals in the presence of seed material in the medium. Therefore, the use of water-insoluble substances as a seed allows you to regulate this process.

Example 1

To obtain 100 kg of product, 20.5 kg of skimmed milk powder is dissolved in water at a temperature of 45 ° C, water-insoluble finely dispersed substance (CaCO ₃ ) is added in an amount of 0.01 kg, stirred, cooled to 6 ° C and held for 30 minutes, heated to 50 ° C and add 4.0 kg of dehydrated molten milk fat and 4.25 kg of soybean oil (normalization for fat 1: 1, since another 0.25 kg of fat is contained in 20.5 kg of skimmed milk powder) 0.03 kg of salt stabilizer; homogenized at 12 MPa; make 43.5 kg of sucrose, the mixture is thoroughly mixed in a container at a temperature of 90 ° C for 10 minutes, cooled to 20 ° C and packaged.

The resulting product has a uniform consistency with condensed milk with sugar with a lactose crystal size of not more than 10 microns, a pure milk taste, moderately sweet.

Example 2

To obtain 100 kg of condensed milk with sugar, 63.84 kg of whole milk is normalized to the ratio Zhpr / SOMOpr = 0.425, heated at 70 ° C, homogenized at 10 MPa, pasteurized at 107 ° C, sugar syrup with a mass fraction of solids is prepared in parallel 65% in the amount of 587.25 kg, the mixture of syrup with homogenized milk is thickened while simultaneously adding water-insoluble finely divided substance (SiO ₂ ) in the amount of 0.02 kg, cooled to 20 ° C and packaged.

The resulting product has a uniform consistency with condensed milk with sugar with a lactose crystal size of not more than 10 microns, a pure milk taste, moderately sweet.

Example 3

Carried out according to Example 2, while the introduction of water-insoluble finely divided substances (MgCO ₃ ) in an amount of 0.03 kg is carried out immediately before filling the product in a can, followed by boiling the product in a jar to produce condensed milk with boiled sugar.

Example 4

Carried out according to Example 2, while the introduction of water-insoluble finely divided substances (TiO ₂ ) in an amount of 0.01 kg is carried out directly in normalized milk and 0.01 kg in sugar syrup.

Example 5

Carried out according to Example 1 or Example 2, while the introduction of a mixture of water-insoluble finely dispersed substances (TiO ₂ and SiO ₂ ) in an amount of 0.02 kg is carried out directly in normalized milk and 0.02 kg when cooled.

Example 7

To obtain 100 kg of concentrated whey with a mass fraction of solids of 30% 600 kg of whey, it is purified on milk separator separators, 0.04 kg of water-insoluble finely dispersed substance (SiO ₂ ) is introduced, pasteurized, concentrated, cooled and poured into industrial containers for its further processing.

Example 8

Carried out according to Example 7, while the introduction of water-insoluble finely divided substances (MgCO ₃ ) in an amount of 0.04 kg is carried out directly during cooling.
