High-bioactivity goat colostrum composite freeze-dried powder and preparation method thereof

Abstract

A high-bioactivity goat colostrum composite freeze-dried powder relates to the technical field of food, comprising the following components in parts by weight: 60-70 parts of goat colostrum powder, 5-8 parts of composite probiotic liposome freeze-dried powder, and 6-9 parts of mannose oligosaccharides; the composite probiotic liposome freeze-dried powder is prepared from the following components: gallic acid, phytosterol, soybean phosphatidylcholine, modified chitosan, and probiotic powder; the probiotic powder is Bifidobacterium longum powder or Lactobacillus acidophilus powder. The invention proposes to prepare modified phytosterol by esterification reaction of gallic acid and phytosterol, and to prepare probiotic liposomes by encapsulating probiotics with the modified phytosterol and soybean phosphatidylcholine, and at the same time introduce carboxymethyl into chitosan to prepare modified chitosan, and to prepare composite probiotic liposome freeze-dried powder by encapsulating probiotic liposomes with the modified chitosan, thereby protecting probiotics, thereby reducing the inactivation of probiotics, and improving their survival rate.
