Abstract

The invention discloses special pine-nut-protein-peptide-enriched antioxidant lozenges for astronauts and a preparation method thereof. The special pine-nut-protein-peptide-enriched antioxidant lozenges for the astronauts are prepared from the following raw materials and auxiliary materials: 20-40% of pine nut protein peptides, 10-20% of blueberry anthocyanin dry-powder, 3-6% of raspberry powder,1-2% of beta-carotene, 2-4% of taurine, 1-2% of vitamin C, 1-2% of vitamin E, 1-2% of alpha-lipoic acid, 8-15% of beta-cyclodextrin, 2-5% of buckwheat starch, 10-15% of xylitol, 2-4% of citric acid, 5-10% of fructo-oligosaccharides, and 2-4% parts of grape powder. The preparation method of the special pine-nut-protein-peptide-enriched antioxidant lozenges for the astronauts is characterized in that the pine nuts with high protein content are taken as raw materials, and the raw materials and the auxiliary materials are proportioned so as to ensure balanced nutrition; and thus, the prepared pine-nut-protein-peptide-enriched antioxidant lozenges have the characteristics of resistance to high-energy particle radiation in the space, small volume, and good taste. The pine-nut-protein-peptide-enriched antioxidant lozenges can be used for activities of astronauts in space stations, aviation pilots, field forces, navigation, submarines and so on. Moreover, the pine-nut-protein-peptide-enrichedantioxidant lozenges can be also used for people with the demands of preventing cardiovascular and cerebrovascular diseases as well as diabetes syndromes, and improving intestinal flora, reducing blood lipid and lowering blood pressure.

Description

technical field [0001] The invention belongs to the field of special-purpose food, and relates to a natural nut anti-oxidation buccal tablet using pine nut protein peptide as a raw material and its preparation. Background technique [0002] With the maturity of aerospace technology, various proposals for developing space and obtaining resources from outer space are also presented to mankind. However, due to the influence of microgravity, low pressure, hypoxia, and radiation, long-term space will It can lead to physiological or pathological changes in the body, and even death in severe cases. In this case, it greatly limits the utilization and exploration of space resources by human beings. Among the pathological changes in the human body caused by space, ionizing radiation damage accounts for about 45%, and oxidation caused by high-energy particles radiated by cosmic rays has attracted much attention. Oxidation is when the body suffers from various harmful stimuli, highly ...
