Chitosan oligosaccharide probiotic yak milk polypeptide formula milk powder and preparation method thereof

Abstract

The invention discloses chitosan oligosaccharide probiotic yak milk polypeptide formula milk powder. The milk powder is prepared from the following raw materials of, in parts by weight, 50-65 parts ofwhole milk powder, 10-30 parts of desalted whey powder, 5-15 parts of whole yak milk powder, 5-15 parts of yak milk protein polypeptide powder, 5-15 parts of chitosan oligosaccharide, 0.005-0.01 partof vitamin C, 0.90-0.95 part of phosphatidylserine, 0.01-0.02 part of bifidobacterium lactis (HN-019), 0.01-0.02 part of lactobacillus acidophilus (NCMF), 0.01-0.02 part of lactobacillus bulgaricus and 0.01-0.02 part of streptococcus thermophilus; and the finished product is prepared through processes of fermentation, centrifugation, ultrafiltration, dry mixing and the like. According to the milkpowder, the components are reasonably matched, the nutrition is comprehensive, high-quality protein is supplemented for human bodies, and meanwhile, the functional oligosaccharide chitosan oligosaccharide contained in the milk powder has the effects of improving the body immunity, reducing the blood fat, regulating the blood sugar, improving the liver and cardiopulmonary functions and other various physiological functions.

Description

technical field [0001] The invention belongs to the field of dairy products, and in particular relates to a chitosan oligosaccharide probiotic yak milk polypeptide formula milk powder and a preparation method thereof. Background technique [0002] Studies have shown that probiotics have multiple effects on the healthy physiology of the body. They can inhibit the harmful bacteria in the intestines, promote the proliferation of beneficial bacteria in the intestines, or reduce the nutrients for the reproduction and growth of pathogens, forming an ecological balance environment of "competitive exclusion" in the intestinal tract , at the same time, produce enzymes for fermenting non-digestible starches, and these non-digestible starches are the main energy substances of the intestinal microbial community. In addition, the body can use the short-chain fatty acids produced by intestinal probiotics to prevent bile from damage to DNA, scavenge free radicals, And regulate their own ce...
