Abstract

The invention provides a natural food preservative used for fruits and preparation thereof. The preservative comprises first smearing liquid and second smearing liquid, wherein the first smearing liquid comprises the following ingredients by weight percent: 0.8%-1.4% of carboxymethyl cellulose, 1-2% of maltodextrin, 0.3%-0.8% of baking soda and the balance of deionized water; the second smearing liquid comprises the following ingredients by weight percent: 1%-1.5% of konjak gum, 0.2%-1% of beewax, 0.5%-2.5% of plant extract, 1%-5% of a solvent and the balance of deionized water. The preservative adopts natural ingredients for protection, is green and safe, achieves the effects of water retention, oxidization resistance, antibiosis and corrosion prevention of the fruits sequentially through multilayer spraying, has multiple functions, effectively reduces metabolism after the fruits are picked, prolongs the preservative period for 15 days or more, has good color keeping and flavor keeping properties, and improves the fruit marketing performance.

Description

technical field [0001] The invention relates to the technical field of fruit fresh-keeping agents, in particular to a natural food fresh-keeping agent for fruits and its preparation.
