Problems solved by technology

However, vegetable production is very seasonal and regional, with high water content, easy to lose water, wilt, rot and deteriorate, and lose a lot in the process of storage, transportation and sales.
At present, the output of vegetable products in my country has an absolute advantage in the world. However, in stark contrast to the development speed of vegetable production, there is a lack of a perfect vegetable post-harvest treatment and fresh-keeping circulation system.

Abstract

The present invention relates to an organic vegetable biological preservative, a preparation method thereof and a matched preservation method. The organic vegetable biological preservative mainly comprises the following components: 0.5-2 parts of inositol hexaphosphate, 3-5 parts of tea polyphenols, 4-8 parts of calcium propionate and 3-5 parts of ethyl sorbate. The provided organic vegetable biological preservative can reduce water transpiration of vegetables, inhibits post-harvest breathing, prevents vegetable spoilage, slows down plant nutrient consumption and chlorosis. Besides, the used raw materials all have relatively high safety and are easy to wash. The preservative is safe, highly efficient and pollution-free.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a biological fresh-keeping agent for organic vegetables, a preparation method thereof and a supporting fresh-keeping method. Background technique [0002] Vegetables are delicious and refreshing, appetizers and food aids, and can provide vitamins, minerals and organic acids that are easily lacking in the human body to ensure people's health, and become an important health food that people like. However, vegetable production is very seasonal and regional, with high water content, easy to lose water, wilt, rot and deteriorate, and lose a lot in the process of storage, transportation and sales. At present, the output of vegetable products in my country has an absolute advantage in the world. However, in stark contrast to the development speed of vegetable production, there is a lack of perfect vegetable post-harvest treatment and fresh-keeping circulation system. According to statist...
