Problems solved by technology

[0005] The invention provides a production method of probiotic donkey milk powder. The method utilizes short-time low-temperature treatment to sterilize the raw milk in production, concentrates it at a low temperature of 20-40°C, and then vacuum freeze-dries it, which overcomes the traditional preparation of donkey milk powder. In the method, high-temperature powder spraying destroys the active ingredients in donkey milk powder and the taste, appearance and solubility of the finished donkey milk powder, which can maximize the retention of active ingredients in donkey milk and probiotics

Embodiment 1

[0029] Such as figure 1 As shown, this implementation provides a production method of probiotic donkey milk powder, which involves low-temperature vacuum concentration of raw donkey milk after heat treatment of the raw material milk. Specific steps are as follows:

[0030] (1) Raw material donkey milk inspection and storage: fresh donkey milk will be inspected according to the acceptance standards of donkey milk, and after passing the inspection, it will be put into storage for production;

[0031] (2) Centrifugal milk cleaning: Use a milk cleaning machine to separate raw donkey milk at a high speed at 0.20 MPa to remove dust, hair and other impurities in donkey milk.

[0032] (3) Homogenization: put the donkey milk heated to 50°C into the homogenization system, and perform homogenization treatment under the condition of 25-30MPa;

[0033] (4) Heat treatment: suck the homogenized donkey milk into a vacuum tank, and put it into a heat treatment system for low-temperature past...

Embodiment 2

[0046] Sterilization of fresh donkey milk at different temperatures found that boiling and above temperatures seriously damage indicators such as albumin, vitamins and minerals in donkey milk, and cause fat to float up, seriously affecting product quality. Under the condition of 85℃ / 15s, it can not only meet the sterilization conditions but also keep the nutrients in the milk.

[0050] Table 3: Comparison of common milk powder production processes

[0051]

[0052] Table 3 compares different milling processes and finds that the vacuum freeze-drying milling technology adopted in the present invention can retain the nutritional active ingredients in donkey milk to the greatest extent.

Embodiment 3

[0054] A probiotic donkey milk powder is obtained by removing impurities, homogenizing and sterilizing the donkey milk, then concentrating in a low-temperature vacuum, adding probiotics after concentration, and using the probiotic donkey milk powder obtained by freeze-drying.

Abstract

The invention discloses probiotic ass milk powder. The probiotic ass milk powder is prepared through the following steps of removing impurities, performing homogenizing, performing sterilization, performing low-temperature vacuum concentration, after concentrating, adding probiotics, and performing freeze drying to obtain the probiotic ass milk powder. The invention further discloses a preparationmethod of the probiotic ass milk powder. According to the method, active components and nutrients of the fresh ass milk are protected to the maximum extent, and the probiotic ass milk powder also hashealth efficacy of the probiotics.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a preparation method of probiotic donkey milk powder. Background technique [0002] At present, the health effects of probiotics are more and more favored by consumers. Probiotics occupy a large share in dairy products. Most of the products are probiotic yoghurt and probiotic drinks, which are very popular among consumers. However, liquid dairy products Short shelf life, storage [0003] The transportation cost is high, and the potential safety hazards are relatively large. In order to prolong the preservation period of live bacteria, the main methods currently adopted are mainly to add high-concentration bacteria powder, preservatives and other additives, or use special packaging, special treatment of the process and other measures to make probiotics The original flavor of the bacteria is weakened, the health effect cannot be fully brought into play and reflected, and the cost is...
