Problems solved by technology

Since the milk composition, composition ratio and structure of goat milk are different from cow milk, the inspection and processing conditions of goat milk in production and processing are different from those of cow milk. Use cow milk standard products to calibrate the milk composition analyzer Rapid detection of goat milk is also inaccurate
At present, there are no standard products for the rapid detection of goat milk components in China or even in the world

Embodiment 1

[0053] Example 1: Preparation of Goat Milk Components Mixed Standards by Pseudo-Horizontal Uniform Design Method

[0054] 1) Take out 6 bottles of milk (about 1300mL) from the freezer, wash them twice with cold water, then thaw them at room temperature, then filter them into a large beaker with double-layer gauze to remove foreign matter and other impurities;

[0055] 2) Divide the filtered goat milk into centrifuge tubes, the volume of which is not more than 2 / 3 of the volume of the centrifuge tube, and then balance it with a tray balance;

[0056] 3) Put the balanced centrifuge tubes in a refrigerated centrifuge, centrifuge at 4°C, 5500r / min for 15min, repeat twice, carry out refrigerated centrifugation, and use a key to dig out the frozen fat in the upper layer, and put the obtained fat in a beaker , seal the mouth of the beaker with plastic wrap, and put it in a 4°C refrigerator for later use;

[0057] 4) Stir the degreased skim milk evenly with a glass rod, filter it int...

Embodiment 2

[0064] Example 2: Preparation of Goat Milk Ingredients Mixed Standards by Equal Level Uniform Design Method

[0065] In order to better determine the method of uniform design, Example 2 adopts the equal-level uniform design method to prepare mixed standards. In this experiment, the lactose was reduced by the gradient difference, set to 3.4%, 3.6%, 3.8%, 4.0%, 4.2%, 4.4%, 4.6%, 4.8%, 5.0%, 5.2%, 10 levels of gradients, taking equal levels The uniform design method, as shown in Table 3. When carrying out sample configuration in this experiment, refer to Table 3 to configure, and the rest of the steps are the same as in Example 1, and the specific configuration table is as shown in Table 4:

Embodiment 3

[0070] Embodiment 3: Add the comparison of the mixed standard substance prepared by the emulsifier group and the control group

[0071] Add an emulsifier—sucrose ester (because the sample needs to be heated and stirred in a 40°C water bath to dissolve after preparation of the standard product, and the sucrose ester is easily soluble in warm water), and the addition amount is 0.2%. In this test, each milliliter of lactose permeate contains about 0.065g of lactose. According to the final mass of 50g of the standard product, it can meet the requirement of lactose mass percentage content, and there is no need to add lactose of analytical grade. When carrying out sample configuration, configure with reference to Table 1, the rest of the steps are the same as in Example 1, and the specific configuration table is as shown in Table 5:

Abstract

The invention discloses a mixed standard product based on rapid detection of goat milk components and its preparation process. The standard product is made according to the following ratio: the mass fraction of protein is 2.6% to 6.2%, with 10 levels; The mass fraction is 2.4%-6.0%, set 10 levels; the mass fraction of lactose is 3.4%-5.0%, set 5 levels. The process combines the previous stage of this project and the verification analysis of the experiment to obtain the mass fractions of protein, fat and lactose in goat milk, and then set the protein and fat to 10 gradient levels, and lactose to 5 gradient levels. The design method prepares a set of 10 mixed standard samples, each standard product has a mass of 50 grams, about 50 milliliters. This standard product can be used to reduce the error in the determination of goat milk components by using a milk component analyzer. It can realize individual performance measurement, monitor the milk production of sheep flocks in sheep farms, and provide scientific data support for genetic breeding of high-yielding sheep flocks. Scientifically and efficiently guide and manage sheep pasture production.

Description

technical field [0001] The invention relates to the development of a standard product, in particular to a mixed standard product based on rapid detection of goat milk components and a preparation process thereof, belonging to the field of food science. Background technique [0002] Milk mainly contains water, fat, protein, lactose, inorganic salts and vitamins, among which protein, fat and lactose are the main components, which are commonly referred to as milk components. Regardless of the milk source, the content of milk components will fluctuate within a certain range, the fat content fluctuates greatly, followed by protein, and the difference in lactose content is not significant in most cases. The change of milk component content is affected by many factors, such as mammal species, lactation period, parity, season, feed, health status and other factors. The laboratory has conducted a comprehensive analysis of the goat milk components of Laoshan dairy goats in different ...
