Castanea mollissima storage and preservation method

Abstract

The invention relates to a castanea mollissima storage and preservation method. Fresh castanea mollissima is picked, dried preliminarily, packaged into gunny-bags, and placed in a storehouse to be stacked and preserved. From the mid-September to October, the temperature of the storehouse is controlled within a range from -0.5 DEG C to +5 DEG C, the humidity is controlled within a range from 70% to 80%, ventilation is conducted on alternate days, and water is added every day or on alternate days; From November to February, the temperature of the storehouse is controlled within a range from -0.5 DEG C to -3 DEG C, the humidity is controlled within a range from 70% to 80%, and water is added every day or on alternate days; and from March to May, the temperature of the storehouse is controlled within a range from -2 DEG C to -4 DEG C, and the humidity is controlled within a range from 70% to 75%. The water adding mode is an atomizing water adding mode. According to the castanea mollissima storage and preservation method, the weight loss ratio of the castanea mollissima can be controlled within a range from 2.5% to 3%, the mildewing rate is controlled at 0.3%, gemmule cannot exceed 0.5mm, the sugar degree is within 30, and the fact that all physicochemical indexes are basically kept unchanged after the fresh castanea mollissima is stored for 12 months is achieved.

Description

technical field [0001] The invention relates to a food storage and fresh-keeping method, in particular to a chestnut storage and fresh-keeping method. Background technique [0002] At present, the storage of chestnuts is often based on the storage of individual farmers. Based on feelings and experience, there is a lack of scientific guidance and unified scheduling, and a lot of waste is caused by improper storage every year. Most of the fresh chestnuts are stored in sand, on shelves, in cold storage, or in buds in the place of origin. The storage effects are different, but the three problems of mildew and corruption, air-dried water loss and germination have always been difficult to solve. Contents of the invention [0003] Aiming at the above-mentioned technical problem in the prior art that chestnuts are greatly wasted due to improper storage, the present invention provides a chestnut storage and fresh-keeping method that effectively prevents chestnuts from mildew and co...
