Abstract

The invention discloses a natural cherry fresh keeping agent and a preparation method thereof, wherein the natural cherry fresh keeping agent comprises, by weight, 17-23 parts of chitosan, 13-18 parts of tea polyphenol, 8-12 parts of calcium propionate, and 940-970 parts of water. According to the present invention, the components of the natural cherry fresh keeping agent are the natural and non-toxic substances, and cannot produce harm to human body; with the natural cherry fresh keeping agent, the cherry storage time can be prolonged to 8 days, wherein the cherry can be stored for 4 days at the room temperature, such that the storage time is doubled, and the fresh keeping effect is significant; and the fresh keeping agent preparation method is simple and is suitable for promotion and use.

Description

technical field [0001] The invention relates to a preservative and a preparation method thereof, in particular to a natural preservative for cherries and a preparation method thereof. Background technique [0002] First of all, cherries are counted. When cherries are on the market, they are in the off-season. However, the fruits of cherries are not resistant to storage and transportation, which seriously restricts their economic benefits. Preservation of cherries is the most difficult of fruits. The harvest period of cherries is relatively concentrated. In order to prolong the supply period of cherries and realize a virtuous circle of cherry production, sales and consumer markets, the storage and preservation of cherries is particularly important. [0003] At present, there are two main methods of preserving cherries: physical preservation and chemical preservation. Among them, the physical fresh-keeping method consumes a large amount of energy in the implementation process...
