Abstract

The invention relates to a fruit and vegetable fresh-keeping agent and a preparation method thereof. The fruit and vegetable fresh-keeping agent comprises the following components: 3-6 parts of glycerin, 20-25 parts of edible alcohol, 0.15-0.4 parts of chitosan, 0.01-0.08 parts of nisin from streptococcus lactis, 0.015-0.08 parts of tea polyphenol, 0.01-0.08 parts of 4-phenylphenol, and 0.5-2.5 parts of beeswax. The method is characterized in that edible alcohol, nisin from streptococcus lactis, and 4-phenylphenol in the fresh-keeping agent can effectively kill the bacteria and resist corrosion, the glycerin and beeswax can form a protection film on the surface of the fruit and vegetable, so that moisture loss of the fruit and vegetable is prevented, tea polyphenol can avoid color loss of the fruit and vegetable, and the color of the fruit and vegetable is more natural. The fruit and vegetable fresh-keeping agent can prolong the preservation period of the fruit and vegetable, so that the fruit and vegetable is fresher and more tasty, and the cost is low.
