Abstract

The invention discloses a surface spraying agent capable of prolonging the shelf life of fruits. The spraying agent consists of the following raw materials in parts by weight: 4 to 6 parts of a melonvine retting matter, 0.5 to 0.8 part of sodium diacetate, 2 to 3 parts of an exocarpium benincasae extract, 5 to 7 parts of gum, 3 to 4 parts of gelatin and 10 to 20 parts of a mixed extracting solution. The surface spraying agent capable of prolonging the shelf life of fruits disclosed by the invention is good in polishing and glossy effects after being used, has the effects of insect expelling,sterilization, fresh keeping and the like, and is natural in ingredients, non-toxic, healthy and high in safety.

Description

technical field [0001] The invention relates to the technical field of fruit preservation, in particular to a pure natural surface spraying agent prepared by using biological preparations and capable of effectively prolonging the shelf life of fruits. Background technique [0002] During the process of picking, storing, processing and selling 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. Therefore, antimicrobial preservatives...
