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

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.

Abstract

The invention discloses a making method of ass milk powder capable of preserving nutrient components. The making method comprises the following steps of firstly performing impurity removal on net milk, performing homogenizing treatment, performing low temperature pasteurization, and then performing low-temperature vacuum concentration so that the concentration of mixed ass milk reaches 40%; and then performing vacuum freeze-drying so as to obtain the ass milk powder. Through adoption of the method, active components and nutrition of raw fresh ass milk can be protected to the maximum extent.

Description

technical field [0001] The invention relates to a production process of concentrated freeze-dried donkey milk powder, in particular to a preparation method of donkey milk powder with preserved nutritional components. Background technique [0002] At present, the conventional milk powder processing method is to make cow's milk or their colostrum through milk cleaning, homogenization, high-temperature sterilization and other processes, and then spray dry it with hot air at 120-170°C. High temperature treatment destroys part of the protein and vitamins in the finished milk powder, inactivates the active protein, and reduces the nutritional value. Excessively high heating temperature will also cause the breakage of the "disulfide bond", causing the milk powder to produce a cooking taste; at the same time, the milk powder The longer the heating time of the lactose in the powder, the more serious its dissimilation structure will affect the quality of the finished milk powder; in a...
