Embodiment 1

[0025] A kind of manufacture method of milk powder comprises the following steps:

[0026] (1) Raw milk pretreatment: according to the conventional method, the raw milk is subjected to sensory identification and physical and chemical inspection, and then filtered, purified, cooled and set aside after passing the test;

[0027] The acceptance of raw materials is initially determined to be qualified milk, and then filtered and purified to remove mechanical impurities and some bacteria.

[0028] (2) dissolving the ingredients in water, fully stirring to obtain the ingredients solution;

[0029] Add the ingredients into the water at 40-50°C and stir well. The equipment used in batching mainly includes batching tank, water-powder mixer and heater. According to the requirements of the formula, the required trace elements and various auxiliary materials are added as ingredients.

Abstract

The present invention provides a method for manufacturing the milk powder. The method comprises the following steps: (1) pretreating raw milk; (2) dissolving ingredients in water, fully stirring them evenly to obtain an ingredient solution; (3) mixing the treated raw milk and the ingredient solution uniformly to obtain a mixed solution; (4) homogenizing the mixed solution, and then conducting sterilization and concentration to obtain concentrated milk; and (5) then adding glutamine transaminase accounting for 0.02-0.08% of the mass of the concentrated milk, stirring the substances evenly, and keeping reaction, and then performing spray drying to obtain milk powder. The method provided by the invention uses glutamine transaminase to replace a thickening agent, and protein reacts to generate a grid structure, so that after brewing the milk powder, the milk liquid has suspension function, the anti-precipitation effect of the milk liquid obtained by brewing of the milk powder can be significantly improved. By adding sodium citrate, the stability of concentrated milk can be increased, the action time of glutamine transaminase is shortened, and its action effect is increased. The method provided by the invention provides a new solution for precipitation prevention of milk powder.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to a method for manufacturing milk powder. Background technique [0002] Milk powder is a prepared food made from raw milk, which is processed by freezing or heating to remove the water in the milk, with or without adding food additives and nutritional fortifiers. With the improvement of people's awareness of health and nutrition and the demand for diversified product flavors, more and more new products of nutritionally fortified modulated milk powder have appeared on the market. These new milk powder products are deeply loved by consumers because of the addition of some ingredients that improve the nutritional value or flavor of the product. However, if some of the added substances are insoluble ingredients, some precipitates will usually form at the bottom of the cup when brewing and dissolving, which will not only bring consumers a bad brewing consumption experience, bu...
