Abstract

The invention discloses a mushroom fresh-keeping agent and a preparation method of the mushroom fresh-keeping agent and belongs to the technical field of fruit and vegetable fresh preservation. The mushroom fresh-keeping agent comprises the following raw materials in parts by weight: 5-10 parts of chitosan, 5-10 parts of vitamin C, 1-5 parts of tea polyphenol, 5-10 parts of pulullan and 100-120 parts of sterile water. The invention further provides the preparation method of the mushroom fresh-keeping agent. The method comprises the steps of mixing the raw materials, and performing ultrasonic dispersion and subpackage. The fresh-keeping agent is directly sprayed onto the surface of picked mushroom after diluted, is convenient to use, can be used for the fresh preservation of a small portion of bagged mushroom and massive warehoused mushroom, has low fresh preservation cost and long fresh preservation time, can prolong fresh storage life of the mushroom to 30 days, achieves good quality control, adequately assures freshness and nutritional ingredients of the mushroom, has no toxic or side effects on a human body, is safe and environment-friendly and meets diversified demands of people on the mushroom.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of fruits and vegetables, in particular to a mushroom fresh-keeping agent and a preparation method thereof.
