Abstract

The invention discloses an antioxidant jelly with natural berries rich in anthocyanin special for astronauts and a preparation method of the antioxidant jelly. The jelly is prepared from the following raw and auxiliary materials: 35-50g of blueberry powder, 25-35g of mulberry powder, 25-35g of blackcurrant powder, 25-35g of cranberry powder, 25-35g of grape powder, 0.3-0.5g of agar, 0.2-0.3g of oligosaccharide and 0.05-0.1g of bifidus factor. The antioxidant jelly has the characteristics that with fruits with high vitamins as raw materials, the vitamin density of the concentrated food is improved on the basis of ensuring the nutrient balance in proportion; the berries such as blueberries, mulberries, black currants and cranberries are selected as raw material sources; the berries are rich in ascorbic acid, vitamin A, vitamin B, vitamin E, vitamin K, vitamin P, carotene, anthocyanin, dietary fiber, fructose, organic acid and the like, so that the oxidative stress effect on the astronauts caused by spatial radiation pollution can be alleviated to a certain extent; and the special antioxidant jelly can reach antioxidant and antimutation effects, and is suitable for being eaten in a space environment.

Description

technical field [0001] The invention belongs to the field of food processing biotechnology, and relates to a variety of anthocyanin-rich natural berry anti-oxidation composite jelly for astronauts and a preparation method thereof. Background technique [0002] With the development of the aerospace industry and the establishment of space stations, astronauts spend more and more time working in space. Therefore, the health of astronauts has become the focus of attention. Due to changes in radiation intensity and gravity in space, the body is in an extreme state for a long time, resulting in a series of physiological changes. In particular, extreme environments induce oxidative damage to the body, causing extremely complex biochemical reactions, in which nutrient metabolism is seriously affected, and vitamins such as ascorbic acid are significantly reduced in the body. If the nutrient metabolism is not adjusted, the imbalance of vitamins in the body will be caused, and the da...
