Embodiment 1

[0016] Choose a vineyard free of diseases and insect pests, spray evenly on the surface of each fruit with a 2.5% wood vinegar solution by volume, and then pick the fruit after the surface of the fruit is dry the next day.

[0017] Strictly sort the fruits when picking. First, ensure that the fruits are free from diseases, insect pests and mechanical damage. Second, they must have inherent characteristics, such as maturity, color, sugar-acid ratio, etc. Then put it into a turnover box (the weight of the fruit should be less than 3kg), pay attention to wear gloves, minimize contact with the fruit, and handle it with care.

[0018] After picking, the refrigerated truck transported to the pre-cooling room (0°C-2°C) for pre-cooling for 12 hours, put the fruit into a box lined with PE plastic wrap, every 3kg fruit / box, and then put 1 bag in each box 1 -MCP preservative (1-MCP preservative is produced by the National Agricultural Products Preservation Engineering Technology Research...

Embodiment 2

[0020] Choose a vineyard free of diseases and insect pests, spray evenly the surface of each fruit with wood vinegar solutions of different volume ratio concentrations, and then pick the fruit after the surface of the fruit is dry the next day.

[0021] Strictly sort the fruits when picking. First, ensure that the fruits are free from diseases, insect pests and mechanical damage. Second, they must have inherent characteristics, such as maturity, color, sugar-acid ratio, etc. Then put it into a turnover box (the weight of the fruit should be less than 3kg), pay attention to wear gloves, minimize contact with the fruit, and handle it with care.

[0022] After picking, the refrigerated truck transported to the pre-cooling room (0°C-2°C) for pre-cooling for 12 hours, put the fruit into a box lined with PE plastic wrap, every 3kg fruit / box, and then put 1 bag in each box 1 -MCP preservative (1-MCP preservative is produced by the National Agricultural Products Preservation Engineeri...

Abstract

The invention discloses a grape fresh-keeping storage method. The method comprises the following steps: uniformly spraying a pyroligneous solution with the volume concentration of 2.5-10% (w / w) to thesurfaces of strings of grapes in a vineyard without plant diseases and insect pests, and performing picking after the surfaces of the grapes are dry in the next day; during picking, strictly sortingand then putting the grapes are into a container, wherein the fruit bearing weight should be smaller than 3 kg; after the picking, enabling a refrigerated truck to be transported to a pre-refrigeration house, performing pre-cooling for 12 h at 0-2 DEG C, and putting the grapes into boxes lined with PE preservative films, wherein every 3 kg of grapes are put into one box; and then putting one bag of 1-MCP preservative into each box, immediately tying the box, and then performing stacking and storing at a temperature of 0+ / -1 DEG C. The fresh-keeping storage period of the grapes can reach 60 days, and the method prolongs the shelf life of the grapes on the basis of ensuring the quality of the grapes.

Description

technical field [0001] The invention belongs to the technical field of storage and preservation of agricultural products, and in particular relates to a method for preservation and preservation of grapes. Background technique [0002] Grapes, Vitis genus, are deciduous vines with high moisture and sugar content, rich nutrition and delicious taste, and are very popular among consumers. However, due to the thinner grape skins, they are easily damaged during the picking process, and are easily infected by pathogens during storage, resulting in problems such as shattering, browning, and rot in the grapes, which affect the freshness of the grapes and cause certain economic losses. At present, the principle of grape preservation technology at home and abroad is mainly sulfur dioxide anticorrosion combined with low temperature storage. [0003] However, the dose of sulfur dioxide that causes damage to grapes is similar to the dose that can effectively sterilize grapes, and the use...
