Probiotics for regulating intestinal flora of astronauts as well as preparation method and application of probiotics

Abstract

The invention discloses probiotics for regulating intestinal flora of astronauts. The probiotics comprise the following components in percentage by mass: 30-45% of intestinal probiotics, 20-30% of lentinan, 10-20% of walnut powder, 10-20% of jujube powder and 10-20% of lily powder. The preparation process comprises the following steps: weighing the raw materials in parts by weight, mixing the walnut powder, the Chinese date powder and the lily powder, adding water, extracting for 8-10 hours, and filtering to obtain an extracting solution; concentrating and crushing the extract liquor to obtain mixed powder; adding lentinan, bifidobacterium, lactobacillus casei and lactobacillus rhamnosus into the mixed powder, and uniformly mixing to obtain a finished product. The food can effectively regulate the balance of intestinal flora of astronauts in a weightlessness state and enhance the immunity.

Description

technical field [0001] The invention relates to the technical field of health care products, and more specifically relates to a probiotic for regulating the intestinal flora of astronauts, a preparation method and application thereof. Background technique [0002] During spaceflight, people are in special environments such as weightlessness, radiation, noise, and small and confined spaces. Due to the redistribution of body fluids, the function of the spleen and stomach is reduced. Astronauts will experience muscle atrophy, bone calcium loss, intestinal flora disorder, Weight loss, decreased immunity and so on. [0003] Studies have shown that microorganisms mutate within a few days in an environment without gravity. Some bacteria have altered gene expression pathways and the bacteria become more virulent. The intestinal tract is the largest bacterial bank in the human body, and the intestinal flora is closely related to human health. Existing data show that, regardless of ...
