Embodiment 1
[0021] Such as figure 1 As shown, this implementation provides a production method for preserving the active ingredients and nutrition of donkey milk powder, by performing low-temperature vacuum concentration on raw donkey milk after heat treatment of the raw material milk. Specific steps are as follows:
[0022] (1) Inspection and storage of raw donkey milk: Fresh donkey milk is inspected according to the acceptance standards of donkey milk. After passing the inspection, it is put into storage for production. The acceptance standards are as follows:
[0023] Table 1. Acceptance criteria for sensory indicators of raw donkey milk
[0024]
[0025] Table 2. Acceptance criteria for physical and chemical indicators of raw donkey milk
[0026]
[0027]
[0028] Table 3. Acceptance criteria for the total number of colonies in raw donkey milk

Embodiment 2
[0051] A preparation method of donkey milk powder with preserved nutritional components, the steps are: firstly carry out clean milk to remove impurities, homogenize treatment and low-temperature pasteurization, then carry out low-temperature vacuum concentration, so that the concentration of mixed donkey milk reaches 40%, and then carry out vacuum Freeze-dry to obtain donkey milk powder.
Embodiment 3
[0053] A preparation method of donkey milk powder with preserved nutritional components, the steps are: firstly carry out clean milk to remove impurities, homogenize treatment and low-temperature pasteurization, then carry out low-temperature vacuum concentration, so that the concentration of mixed donkey milk reaches 40%, and then carry out vacuum freeze-dried to obtain donkey milk powder,
[0054] The cleaning and impurity removal of the milk is as follows: under the conditions of a temperature of 40-50° C. and a vacuum pressure of 0.20 MPa, high-speed separation of fresh donkey milk at 5000 rpm in a centrifuge.
