Formula and making method of radiation-resistant blueberry composite residue-free instant tea special for astronauts

Abstract

The invention discloses a formula and making method of radiation-resistant blueberry composite residue-free instant tea special for astronauts. The radiation-resistant blueberry composite residue-free instant tea can be used as a daily health-care beverage of the astronauts. The instant tea is processed from main raw materials of green tea powder, a blueberry extract, a spirulina extract, a citrus extract, a Chinese wolfberry fruit extract, a ginseng extract, a glossy ganoderma extract, a poria cocos extract, strawberries, carrots, haws, xylitol and maltodextrin. According to the making method disclosed by the invention, vacuum freeze-drying is combined with a room-temperature wet method granulation technique, and homogeneous instant tea granules are obtained. The harm of active components in the raw materials can be effectively avoided, the flavor of the instant tea is furthest reserved, and the instant tea is convenient to preserve and eat. In addition, green tea instant powder obtained through working procedures of ethanol reflux extraction, polyacrylamide purification, decompression vacuum concentration and freeze drying is favorable in solubility and pleasant in color and flavor. The instant tea not only can be used as a functional health-care beverage special for the astronauts but also can be used as a daily protection food for crowds under radiation environment.

Description

technical field [0001] The invention relates to a formula and a preparation method of anti-radiation blueberry composite non-residue instant tea specially used for astronauts, and belongs to the field of special-purpose food. Background technique [0002] Cosmic rays are high-energy particles released by supernovae and other galactic explosions that travel through space. Cosmic rays can change the shape of nerve cells and damage memory and other cognitive abilities of astronauts. High-energy radiation is the biggest threat to the safety of astronauts among various space environmental factors. High-energy electromagnetic radiation or particle radiation penetrates human cells, ionizes the molecules that make up cells, and destroys the normal functions of cells. When DNA is damaged, the damage to cells is the most serious, and DNA mutations can be passed on to future generations. When the human body receives a certain dose of radiation, it will suffer from radiation sickness. ...
