Abstract

The invention discloses a special compressed food prepared by taking berries as raw materials and used for supplementing vitamins to astronauts and a processing method of the special compressed food. The compressed food is prepared from freeze-dried blueberry powder, freeze-dried indigo honeysuckle powder, freeze-dried strawberry powder, freeze-dried raspberry powder, freeze-dried kiwifruit powder and freeze-dried blackcurrant powder. The compressed food is characterized in that fruits with a high content of vitamins are used as raw materials, and the fruits are processed by adopting a low-temperature compressing technology so that the vitamins can not be destroyed in the processing process and the compactness of the vitamins in the compressed food can be improved on the basis of guaranteeing the balanced matching of nutrients. Because blueberries, indigo honeysuckle, strawberries, raspberries, kiwifruits, blackcurrant and other berries are used as the raw materials for preparing the special compressed food, the special compressed food can supplement the vitamins and other nutrients and also can well prevent a series of physiological changes of the astronauts due to the change of radiation intensity and gravity in space under long-term flight in extreme conditions, and particularly the extreme-environment induced oxidative damage to the bodies of the astronauts.

Description

technical field [0001] The invention belongs to the field of special-purpose food, and relates to a vitamin supplement compressed food with berries as raw materials and a processing 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 damage to the body from the extreme...
