Abstract

The present invention belongs to the technical field of health-care products and particularly relates to a probiotic nutritional preparation suitable for astronauts. The probiotic nutritional preparation comprises 15%-20% of bifidobacterium lactis, 8%-12% of lactobacillus plantarum, 10%-15% of lactobacillus casei, 9%-16% of lactobacillus rhamnosus, 25%-30% of fructooligosaccharide and 20%-25% of xylooligosaccharide; the bifidobacterium lactis, lactobacillus plantarum, lactobacillus casei and lactobacillus rhamnosus are bacterium strain freeze-dried powder. The product aims at special needs ofthe astronauts and properly matches bacterium flora and prebiotics, during the preparation process of the freeze-dried powder, a self-made protective agent is added to improve activity of the variousmicroorganisms, so that the final product has high activity, can directly reach intestinal tracts and is good in effects, and the probiotics match the prebiotics and are efficient in reproduction.

Description

technical field [0001] The invention belongs to the technical field of health products, and in particular relates to a probiotic nutritional preparation suitable for astronauts. Background technique [0002] Probiotics are a class of active microorganisms that are beneficial to the host. They colonize the human intestinal tract and reproductive system and can produce definite health effects, thereby improving the host's micro-ecological balance and exerting beneficial effects. The general term for active beneficial microorganisms. Beneficial bacteria or fungi in humans and animals mainly include Clostridium butyricum, lactic acid bacteria, bifidobacteria, Lactobacillus acidophilus, actinomycetes, and yeasts. At present, the most powerful products researched in the world are mainly compound active probiotics composed of the above-mentioned various microorganisms, which are widely used in the fields of bioengineering, industry and agriculture, food safety, and life and health....
