Abstract

The invention provides a novel pure yak milk tablet and a processing process thereof. The process is characterized in that fresh yak milk is subjected to non-thermal sterilization, is then concentrated in a vacuum low-temperature concentration machine and is subjected to freeze drying; the obtained milk powder is subjected to fresh milk spraying under the stirring condition or the milk powder is added with water to be prepared into milk liquid to form milk powder particles capable of being tabletted; then, the milk powder particles are conveyed to a tabletting machine to be pressed into tablets; after the vacuum drying is performed, pure yak milk tablet finished products are obtained. Advanced non-thermal sterilization equipment is used, and the vacuum low-temperature concentration machine and a freeze drying machine are combined; the fresh yak milk is processed into milk powder; any binding substances and additives are controlled not to be added; the milk powder and milk liquid only made by fresh milk or water are proportionally mixed and tabletted; the made pure yak milk tablet is golden yellow and oleosus; the hardness and the softness are proper; the milk fragrance is sufficient; the novel pure yak milk tablet can easily melt after entering the mouth; the aftertaste is fragrant, sweet and refreshing; the physiological activity of functional ingredients in health care food is favorably maintained; the color, the fragrance, the favor and the nutritional ingredients are favorably maintained; the efficacies of health care, disease prevention and body building can be fully achieved.

Description

technical field

[0001] The invention belongs to the technical field of dairy product processing, and in particular relates to pure yak milk flakes and a processing technology thereof. Background technique

[0002] Modern science has confirmed that yak milk has the characteristics of high concentration, high specific gravity, and high content. It is rich in protein, lactose, milk calcium, zinc, lactoferrin, immunoglobulin, conjugated linoleic acid, unsaturated fatty acids, amino acids, and vitamins. and other natural nutrients. Compared with ordinary milk, the protein content in yak milk is 0.83 times higher, the calcium content is 0.88 times higher, vitamin E is 1.11 times higher, and lysine is 1.24 times higher. Among them, building the immune system is the most The key nutrients-immunoglobulin, conjugated linoleic acid and zinc are even higher than the standard of ordinary milk. Immunoglobulin is an animal protein with antibody activity and is the most important element fo...

Examples

Embodiment 1

[0034] Embodiment 1 diameter 1cm circular pure yak milk slice and its processing technology

[0035] Include the following steps:

[0036] S1. The fresh yak milk is transported through pipelines to the sterilization tank of the ultrasonic sterilizer for ultrasonic sterilization. Set the ultrasonic frequency to 45khz, the pulse width to 8ms, and the ultrasonic time to 7min.

[0037]S2, transport the sterilized fresh yak milk to the liquid storage tank of the vacuum cryogenic concentrator through a sterile pipeline, set a vacuum of 10pa, a temperature of 60°C, centrifuge at 1500 rpm, concentrate to a water content of 60%, and then concentrate the concentrated The fresh yak milk is transported to the container box of the freeze dryer through a sterile pipeline, and the freezing temperature is set at -55°C to make ice milk, and the vacuum degree is 19pa, and the yak milk powder is dried to a moisture content of 7%;

[0038] S3. Transport the dried yak milk powder through a steri...

Embodiment 3

[0050] Example 3 Animal-shaped pure yak milk flakes and its processing technology

[0051] Include the following steps:

[0052] S1. The fresh yak milk is transported through the pipeline to the sterilization container of the QFP 687l-300HPP ultra-high pressure normal temperature sterilizer produced by Avure Technologies in the United States for ultra-high pressure normal temperature sterilization. The conditions for setting ultra-high pressure normal temperature sterilization are as follows: in a closed ultra-high pressure container, use water as the medium under a pressure of 450 MPa, control the temperature at 40°C, and sterilize for 29 minutes. Alternatively, use high-grade hydraulic oil ORITES AT 272 (synthetic polyether anti-wear lubricant for ultra-high pressure compressors) as the medium, and sterilize at 45°C for 25 minutes under a pressure of 600MPa.

[0053] S2, transport the sterilized fresh yak milk to the liquid storage tank of the vacuum cryogenic concentrator ...
