Abstract

The invention discloses a fresh-keeping storage method for Chinese chestnuts and relates to the technical field of agricultural product storage. The method comprises the following steps: (A) picking up Chinese chestnuts, namely harvesting the Chinese chestnuts when 35-40% of chestnut shells crack and brown nuts are exposed on a Chinese chestnut tree; (B) putting Chinese chestnut seeds into a solution containing 3% salt and 1% sodium carbonate for rinsing for 2-3min, taking out the Chinese chestnut seeds for cooling, paving a layer of cereal chaff at a cool and ventilated part, paving a layer of Chinese chestnuts upwards in sequence, covering the surface with the cereal chaff which is 2-3cm thick; and (C) taking out the Chinese chestnut seeds after a month, cleaning and airing the Chinese chestnut seeds by using clean water, loading the Chinese chestnut seeds into a plastic bag with a plurality of air holes, putting the plastic bag into a room with good ventilation, and opening an opening of the plastic bag for ventilating if the indoor temperature exceeds 10 DEG C. Compared with the prior art, the Chinese chestnut seeds are relatively low in moisture content and beneficial to store, the Chinese chestnut seeds are prevented from being damaged by worms and rotten, and shrinkage of the Chinese chestnut seeds caused by dehydration is prevented; and the rate of intact fruits after the Chinese chestnuts are stored for 6 months reaches over 85% and the original flavor is basically kept.

Description

technical field [0001] The invention relates to the technical field of agricultural product storage, in particular to a chestnut fresh-keeping storage method. Background technique [0002] Chestnut is rich in unsaturated fatty acids and vitamins, and also contains extremely high sugar, fat, protein, calcium, phosphorus, iron, potassium and other minerals, as well as vitamins C, B1, B2, etc., which have the effect of strengthening the body; Sweet and fragrant, deeply loved by consumers. Because chestnuts have hard shells, large grains, and water content as high as 45-55%, and the temperature and humidity are high during the harvesting period of chestnuts, they are prone to insects and mildew during storage, or lose water and shrink and lose their original color. Flavor, difficult to keep fresh and store. Contents of the invention [0003] The problem to be solved by the present invention is to provide a fresh-keeping and storage method for chestnuts, which can solve the p...
