Abstract

The invention relates to a bacterium-resistant film coating agent for fresh keeping of tangerine fruits. The film coating agent consists of the following raw materials in parts by weight of 10-15 parts of pomelo peel fermentation liquor, 0.6-0.9 part of potassium sorbate, 0.3-0.5 part of di-n-octyl phthalate, 3-5 parts of gum, 1-2 parts of shellac, and 7-12 parts of a plant extracting solution, wherein the plant extracting solution is prepared by mixing Indian strawberry, herba lysimachiae, japanese thistle herb or roots and fructus forsythiae in the compounding ratio of the Indian strawberryto the herba lysimachiae to the Japanese thistle herb or roots to the fructus forsythiae being (0.5-1) to (2-3) to (1-3) to 2 and performing extraction. The compound bacterium-resistant film coating agent for fresh keeping of tangerine fruits, which mainly adopts natural plant components as main materials, is natural in components and free from toxins, has good effects of expelling parasite, restraining bacteria, keeping fresh and polishing, can effectively prolong the fresh keeping period, the storage period and the shelf life of the tangerine fruits, and is high in health and safety properties.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of fruits and vegetables, in particular to a pure natural antibacterial coating agent for fresh-keeping citrus fruits prepared by using biological agents, a preparation method and application thereof. Background technique [0002] During the process of picking, storing, processing and consuming fresh fruits, they are easily spoiled and deteriorated, resulting in huge waste of resources and economic losses. While decaying and losing, pathogenic microorganisms can also produce a large amount of toxins, endangering people's health. According to incomplete statistics, about 10% to 20% of fresh fruits in developed countries are rotten due to microorganisms, and the proportion in developing countries is as high as 40% to 50%. The output of perishable characteristic fruits in China is about 116 million tons, the postharvest loss is about 25%~30%, and the economic loss is about 70 billion yuan. Th...
