METHOD FOR PRODUCTION OF LOW LACTOSE MILK BEVERAGE FOR GERONTOLOGICAL DIETARY ALIMENTATION Russian patent published in 2013 - IPC A23C23/00 

FIELD: food industry.

SUBSTANCE: invention relates to dairy industry, in particular, to production of milk beverages intended for senior persons alimentation. The method involves mixing milk, normalised in terms of fat content, with preliminarily reconditioned dry defatted milk, the mixture pasteurisation, cooling to 4-6°C, β - galactosidase enzyme introduction, lactose fermentation implementation, the mixture maintained (lightly stirred) at a temperature of 4-5°C, the mixture subsequent heating up to a temperature equal to 35-40°C, addition of water solutions of vitamin C, vitamin B_c, ferrous sulphate, zinc sulphate, potassium citrate and preliminarily prepared emulsion of fat-soluble vitamins with lecithin into the mixture (the emulsion produced by way of taking a portion of normalised pasteurised milk mixture wherein, after the latter heating up to 60-85°C, vitamins A, E, D₂ and lecithin are introduced); then one performs stirring and emulsification in the homogeniser, the produced mixture stirring, UHT-sterilisation, cooling to 78°C, homogenisation, cooling and dispensing at the following components ratio, wt %: normalised milk - 40.9-92.5, dry defatted milk - 3.9-7.0, potassium citrate - 0.1, ferrous sulphate - 0.00844, zinc sulphate - 0,00618, vitamin A - 0.0002, vitamin E - 0.00096, vitamin C - 0.01285, vitamin D₂ - 5-10^-7, vitamin B_c - 4.5-10^-5, lecithin - 0.5, soluble β - galactosidase enzyme - 0.040-0.043, water - balance.

EFFECT: invention allows to enhance the ready product quality due to ensuring higher biological value and organoleptic indices and to ensure microbiological purity.
