Abstract

The invention discloses a microecological green preservative for waxberries and a preparation method of the microecological green preservative, belongs to the field of fruit and vegetable preservation, and mainly solves the problem that the storage period of the waxberries at a normal temperature is short. The microecological green preservative for waxberries is liquid microecological preservative, and is composed of active microorganisms beneficial to a human body and film-forming agents, the active microorganisms are phellinus igniarius and saccharomycetes, and the film-forming agents are okra polysaccharide and chitosan. The active microorganisms inhibit waxberry putrefying bacteria through antagonism, and the film-forming agent forms a film to inhibit respiration of the waxberries and slow down the aging of the waxberries, so that the fresh-keeping period of the waxberries is prolonged. The used active microorganisms and the film-forming agents are edible, safe, reliable and good in fresh-keeping effect, the normal-temperature storage period of the waxberries can be prolonged for 3 to 4 days, and the used raw materials have low price and are beneficial to popularization.

Description

technical field [0001] The invention relates to a food fresh-keeping agent, in particular to a red bayberry micro-ecological green fresh-keeping agent and a preparation method thereof, belonging to the technical field of fruit and vegetable fresh-keeping. Background technique [0002] Bayberry (Myrica rubra Sieb.et Zucc) is a specialty fruit in my country, and its cultivated area accounts for more than 99% of the world's total. It is mainly produced in Fujian, Zhejiang, Guangdong, Jiangxi and other areas south of the Yangtze River Basin. Its fruit is bright in color, sweet and sour, and rich in nutrition. It is rich in vitamins, cellulose, minerals, zinc, iron, potassium and other trace elements and Nutrients such as amino acids can help digestion, increase appetite, astringent, anti-inflammatory and anti-diarrheal, anti-cancer and anti-cancer, heat-dispelling and promoting body fluid, etc. It has both edible and medicinal value, and is deeply loved by consumers. Red bayber...
