Fresh-keeping storage method for grape grains

Abstract

The invention discloses a fresh-keeping storage method for grape grains, and belongs to the technical field of agriculture. By spraying a preservative and a bactericide before harvesting, the toughness of fruit stems is increased, the grain falling is reduced, and the fungal diseases of the fruits and the fruit stems are reduced; and after a whole string is pre-cooled, spike cutting and grain dividing are carried out, grape grains with stems are put into a special grape grain storage device to be treated and preserved, grain falling and rotting caused by mutual extrusion and collision of grapes are reduced through storage of the grape grains with stems, and the preservation time is prolonged and is 1-2 times the time length of common grape storage. Through the small-package e-commerce logistics of the grape grains, the problem that fruits with excessive ethanol taste cannot be eaten due to extrusion crushing or anaerobic respiration in the transportation process of the grapes is effectively solved. Meanwhile, the defect that a large amount of carbon dioxide and ethyl alcohol are generated due to respiration of fruit stems in the grape storage process is overcome, the fresh-keeping period of the grapes is finally prolonged, and meanwhile the effects of decay and alcoholization are avoided in the storage period.

Description

technical field [0001] The invention relates to a method for fresh-keeping and storing grape grains, belonging to the technical field of agriculture. Background technique [0002] 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 grapes are degraded or even moldy due to improper post-harvest fresh-keeping measures every year. Among them, post-harvest threshing of grapes 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-harvest grape shattering accounts for about 20% of the post-harvest storage and fresh-k...

AI Technical Summary

Problems solved by technology

Among them, the temperature of low-temperature storage of grapes is generally -1 ~ 0 ℃, but when the relative humidity of low-temperature storage is low, the grape stems are easy to dry, resulting in grain loss, and when the grapes are taken out of the low-temperature environment and placed in the normal temperature environment for sale , the threshing phenomenon is more serious

The chemical antiseptic and antibacterial agents used in postharvest storage and transportation of grapes still use sulfur dioxide and sulfide as the main components. Residues of sulfur dioxide are likely to cause environmental and food pollution, and at the same time endanger human health. As consumers are concerned about these edible safety hazards, Cannot meet the needs of today's consumer population
