Problems solved by technology

[0003] Difficulty in storing chestnuts is the biggest problem affecting chestnut sales. Under normal circumstances, chestnuts can only be stored for a maximum of 3 months, and the storage loss of chestnuts should reach between 10% and 20%. Moreover, chestnuts are prone to worms when stored for a long time. The storage cannot prevent and suppress pests, and it is easy to cause great economic losses.

Embodiment

[0016] A method for storing and preserving chestnuts, comprising the following steps:

[0017] (1) Warehouse management: there are multiple fans on both sides of the warehouse, starting the fans can form convective wind to cool the warehouse. There are 12 temperature and humidity probes in the warehouse. For 1-ton shelves, keep a distance of 1 meter between adjacent shelves, and keep a distance of 3 meters between the shelf and the fan outlet;

[0018] (2) Harvesting and storage: Harvest mature chestnuts by picking chestnuts, select, grade, pack and store the harvested chestnuts, remove moldy, browned, and deteriorated chestnuts, and use 25 kg / pack of chestnuts. Packed in sacks and stacked on the shelves in a well-shaped pattern;

[0019] (3) Pre-storage treatment: seal the warehouse, and use a concentration of 0.5 μL*L for newly entered chestnuts -1 The 1-MCP was fumigated for 8 hours, and the fumigation temperature was kept at 4°C;

[0020] (4) Storage management: The che...

Abstract

The present invention discloses a castanea mollissima storage and freshness retaining method which includes the following steps: warehouse management, harvesting and storing, processing before storage, and storage management. Compared with the prior art, the castanea mollissima storage and freshness retaining method has the following advantages: the method is simple, and is relative low in storage cost; the use of gunny bags for packaging can ensure ventilation and water content soaking, guarantee a certain temperature and humidity in the storage management, and facilitate carrying and management; the newly stored castanea mollissima are subjected to fumigation treatment with 1-MCP, which can slow castanea mollissima oxidation, inhibit oxidative enzyme activity, and reduce the browning degree of castanea mollissima. Epigallocatechin gallate is added in the spraying water during the late storage of the castanea mollissima, has significant preventive and control effects for bacteria and pests, and can enhance the preservation effects of castanea mollissima.

Description

technical field [0001] The invention belongs to the technical field of food storage, and in particular relates to a method for storing and keeping fresh chestnuts. Background technique [0002] Chestnut is rich in nutrients, and its vitamin C content is higher than that of tomatoes, and more than ten times that of apples. The minerals in chestnuts are also very comprehensive, including potassium, zinc, iron, etc. Although the content is not as high as that of hazelnuts, it is still much higher than ordinary fruits such as apples, especially the potassium content is 3 times higher than that of apples. [0003] Difficulty in storing chestnuts is the biggest problem affecting chestnut sales. Under normal circumstances, chestnuts can only be stored for a maximum of 3 months, and the storage loss of chestnuts should reach between 10% and 20%. Moreover, chestnuts are prone to worms when stored for a long time. Such storage cannot prevent and suppress pests, and it is easy to caus...
