Problems solved by technology
Planting chestnuts is an important way for farmers to get rid of poverty and become prosperous. However, due to the inherent physical characteristics of chestnuts, their water content reaches 49.6%, and starch accounts for 70% of the edible part. Therefore, freshly picked chestnuts generate a lot of heat due to their vigorous breathing. Cause mildew and rot, causing great losses to fruit growers, and dehydration and preservation lose the original flavor of chestnuts
In order to solve this chestnut preservation problem, the usual method is to put the newly picked fresh chestnuts into the freezer for refrigeration and preservation, but it is still difficult to meet the purpose of freshness storage and transportation because of the high cost of use and the inability to transport long distances.
At present, some chestnut storage and preservation techniques have been proposed both at home and abroad, such as the chestnut storage and preservation technique with the application number 02136800.7 invented by the Zhejiang Academy of Agricultural Sciences. , and it is not suitable for the long-distance transportation of chestnuts and the needs of off-site preservation

Embodiment Construction
[0006] The present invention will be further described below in conjunction with embodiment.
[0007] Taking the family small-scale as an example, the method of chestnut storage and preservation mainly includes the following steps: firstly, the chestnut buds that meet the harvesting standard are harvested in time; Remove the bract shell and take out the chestnut; put 7 jin of activated carbon, 40 jin of stone sodium and 3 jin of rosin into a large pot and heat to melt. Then immerse the leaky cover containing the chestnuts in the pot and take them out immediately. After the chestnuts see the air, the surface layer is sealed by a layer of film. Then pack it in pieces, and the weight of each piece should not exceed 20 kg.
[0008] Taking industrialized large-scale production as an example, firstly, mature fresh chestnuts are purchased from farmers or sellers, and activated carbon, sodium natrium, and resin are placed in a liquid tank at a ratio of 15:80:5 to heat and melt, and t...

The vacuum freshness preserving method for Chinese chestnut features that cleaned Chinese chestnut is instantly soaked inside molten preserving agent solution so as to form one sealing preserving film on the surface of each Chinese chestnut. The said method prolongs the preserving period of Chinese chestnut under natural condition to one year, and may be used in small scale storing at normal temperature and large scale industrial production.
Description
technical field [0001] The invention relates to the field of food preservation, in particular to a method for long-term storage and preservation of individual chestnuts sealed. Background technique [0002] Chestnut is a famous and high-quality dried fruit with rich nutrition, high economic value and easy absorption by human body, so it is very popular among people. my country is the main producer of chestnuts, especially Luotian County in our province is the "hometown of chestnuts" in the country. Planting chestnuts is an important way for farmers to get rid of poverty and become prosperous. However, due to the inherent physical characteristics of chestnuts, their water content reaches 49.6%, and starch accounts for 70% of the edible part. Therefore, freshly picked chestnuts generate a lot of heat due to their vigorous breathing. Cause mildew and rot, cause great loss to the fruit grower, and dehydration preservation has lost the original local flavor of ...
