Embodiment 1

[0047] An active milk protein extracted from yak milk, the contained active components and weight ratio are as follows:

[0048] β-lactoglobulin 52.0g

[0049] Alpha-lactalbumin 21.5g

[0050] Bovine Serum Albumin 11.0g

[0051] Lactoferrin 1.5g

[0052] Immunoglobulin 12.0g

[0053] Other Micronutrients 2.0 g

[0054] A method for extracting active milk protein from yak milk, the process steps comprising

[0055] A. Selection of raw materials

[0056] Choose pure fresh, natural and pollution-free yak milk emulsion, the protein content of which is 4.5-6.5%.

[0057] B. Centrifugal removal of impurities and fat removal

[0058] Place the pure, natural and pollution-free yak milk emulsion in a centrifuge tank for centrifugation, first remove the cells and impurities in the yak milk emulsion at a temperature of 8°C, and then remove the fat in the yak milk emulsion at a temperature of 25°C. The degreasing and degreasing time were controlled at 10 minutes and 20 minutes res...

Embodiment 2

[0077] An active milk protein extracted from yak milk, the contained active components and weight ratio are as follows:

[0078] See Table 1;

[0079] Table 1 Comparison of the main components of yak milk and cow milk (%)

[0080]

[0081] The test results of mineral content in 10 yak milk samples and 10 dairy cow milk samples showed that the content of phosphorus, iron, magnesium, sodium, calcium and selenium in yak milk was significantly higher than that of cow milk, and the content of potassium was lower than that of cow milk. The difference was significant, P<0.05 , see Table 2;

[0082] Table 2 Comparison of mineral content in yak milk and cow milk (mg / kg)

[0083]

[0084] The test results of amino acid content in 10 yak milk samples and 10 dairy cow milk samples showed that compared with cow milk, the 17 kinds of amino acid content were significantly higher than cow milk, the difference was significant, P<0.01; see Table 3

[0085] Beta-lactoglobulin 53.1g

Abstract

The invention provides an active lactoprotein extracted from yak milk and its extraction method and use, wherein the active constituents by weight include beta-lactoglobulin 51-54, alpha-lactoglobulin 20-23, albumin bovine 9.0-11, lactoferrin 1.0-2.0, immunoglobulin 11-14, other trace nourishing elements 1.0-2.0, the preparation comprises the steps of choosing raw material, removing impurities and degreasing through centrifugation, low-temperature sterilizing, condensating the milk, degerming and thickening, thin film evaporating, freeze drying and asepsis vacuum packaging. The extracted active milk protein has substantial function for enhancing cell vitality and body defensiveness.

Description

Technical field: [0001] The invention relates to an active milk protein and its biological extraction method and application, in particular to an active milk protein extracted from yak milk and its method and application. Background technique: [0002] Yak is a unique livestock in high-altitude areas. It is the only primitive animal species in the genus Bovine without a breed structure. Milk production is an important production performance of yaks. Yak milk is an important food for people in pastoral areas. Milk and its milk products, ghee and milk Slag is the source of animal food and nutrition for the plateau people. Yak has the advantages of high milk fat rate and protein content, rich in amino acids, multivitamins, trace elements, lactose and other nutrients. Since yaks are fed on all-natural pastures without any artificial feed or additives, their milk and milk The product is nutritious and non-polluting, and it is a high-quality raw material for the production of yak...
