Embodiment 1

[0033] like figure 1 As shown, this implementation provides a production method of milk powder that preserves nutrition. After skimming the raw milk, the skim milk is sterilized by low-temperature microfiltration to ensure the nutrition in the skim milk to the greatest extent. This method can produce whole milk Whole-nutrition milk powder and skimmed whole-nutrition milk powder, the production method uses ceramic membrane microfiltration sterilization equipment to filter skimmed cow, goat milk or their colostrum to filter out miscellaneous bacteria, and the retention rate of miscellaneous bacteria is 99.94% %, the spore retention rate is 99.86%; the diameter of fat globules in cow and goat milk is between 0.1 and 22 microns, and the fat content of fat with small diameter in goat milk is relatively higher, because this size basically covers all the bacteria in the milk Therefore, before sterilization and filtration, the fat is separated; specifically, cow, goat milk or their co...

Embodiment 2

[0058] In this embodiment, fresh bovine raw milk is used as raw material to produce freeze-dried milk powder, and the production method of freeze-dried milk powder is described, specifically as follows:

[0059] Step 11. Raw milk inspection: inspect the fresh milk according to the quality inspection standard;

[0060] Step 12. Milk cleaning: Use a centrifuge at 45°C to perform high-speed separation to remove impurities, dust and various non-milk cells in the raw milk;

[0061] Step 13. Preheating: heat the purified purified milk to 38°C;

[0062] Step 14, degreasing: the degreasing machine separates the cream;

[0063] Step 15, temperature adjustment: the skim milk is adjusted to 50°C;

[0064] Step 16, Microfiltration: Put the skim milk into the microfiltration system, first pump it into the microfiltration tank, and then put it into the circulating microfiltration system by the feeding pump, adjust the microwave speed to 10m / s, and the reverse pulse frequency is 35 times / ...

Abstract

The invention discloses a milk powder production method for keeping nutrition. The method comprises the steps as follows: the inspected raw milk is purified to separate the impurities; the purified milk is heated to 50 DEG C; the fat in the separated purified milk is degreased so as to obtain skimmed milk; the skimmed milk is heated to 50 DEG C so as to carry out the micro-filtration disposal for sterilization; the micro-filtration diameter is 0.1-22mm; the entrapped solution obtained by the micro-filtration disposal or the mixed solution obtained by mixing the entrapped solution and the cream obtained by the degreasing disposal is heated to 80-85 DEG C and the temperature is kept for 5-10min for sterilization; the sterilized entrapped solution or mixed solution is mixed with the filtrated solution obtained by the micro-filtration disposal so as to obtain the mixed latex; the mixed latex is concentrated under the vacuum so as to remove the goaty flavour in the mixed latex; the mixed latex with the goaty flavour removed is homogenized under the high pressure and frozen dryly so as to obtain the dry milk powder with the water content of 1-4%, thus obtaining the finished milk powder or degreased milk. The method protects the nutrition in the raw milk to the utmost extent and obtains the milk powder with full nutrition.

Description

technical field [0001] The invention relates to a production process of milk powder, in particular to a milk powder production method capable of preserving the nutrition of milk powder. Background technique [0002] The conventional milk powder processing method is to concentrate goat milk or cow milk, or their colostrum through multi-effect vacuum concentration equipment to remove part of the water in the milk. The concentration temperature is generally between 45-85°C. After concentration, use The concentration of milk reaches about 40-48%. It is made by high-temperature sterilization at 137-142°C, and then spray-dried with hot air at 120-170°C. After multiple high-temperature processing, the protein and vitamins in the finished milk powder are partially destroyed, and the protein The activity of the milk is lost, the nutritional content is greatly reduced, and the "disulfide bond" will be broken if the heating temperature is too high, so that the dairy product has a cooki...
