A kind of antistaling agent that suppresses the shedding of grape fruit grains and its preparation method and application

Abstract

The invention provides a fresh-keeping agent capable of inhibiting falling of grape fruits, and a preparation method and an application thereof, and belongs to the technical field of food fresh keeping. The fresh-keeping agent contains, according to per liter of a solution, 10-30 mg of selenized carrageenan, 15-45 mg of selenic acid lipopolysaccharide, 10-30 mg of maleic hydrazide, 20-40 mg of gibberellins, and 120-200 g of a Chinese herbal medicine extraction liquid. The invention also provides the preparation method and the application method of the fresh-keeping agent. The fresh-keeping agent is composed of the Chinese herbal medicine extraction liquid, plant hormones and organic selenium which are harmless to the environment, and can effectively control the fruit falling condition of fresh-eating grapes during postharvest preservation when being used in grape flowering and young fruit periods.

Description

Technical field

[0001] The invention relates to the field of food fresh-keeping, in particular to a fresh-keeping agent for inhibiting the shedding of grape fruit grains, a preparation method and application thereof.

technical background

[0003] Grape occupies an important position in the world and my country's fruit tree production. It is one of the six main tree species of my country's fruit trees, and it is also a kind of raw food and processed fruit that people like. However, with the rapid development of my country's grape industry, there is a huge pressure on the post-harvest storage, transportation and fresh-keeping of grapes. At present, about 30-35% of the grapes are degraded or even moldy due to improper post-harvest fresh-keeping measures every year, and the shedding of grape grains after harvesting is one of the main reasons for the decline in fruit quality and the impact on its commodity value. According to statistics, the fruit loss caused by post...
