Calcium-sprayed freshness preserving method for processing of agricultural products

Abstract

The invention discloses a calcium-sprayed freshness preserving method for processing of agricultural products. According to the method, a calcium solution is prepared, and the agricultural products are sprayed with a spray gun before picking the agricultural products, so that microbial invasion can be effectively inhibited, and the rotting rate can be effectively lowered; and the picked agricultural products are placed and soaked in the prepared calcium solution, a calcium chloride solution soaking method is employed mainly, then, calcium ions can effectively infiltrate into tissue of fruits by using depressurized infiltration, calcium can be distributed in regions such as cell walls, vacuoles, endoplasmic reticula and mitochondria and is in dynamic equilibrium with calcium in cytoplasm, thus, calcium outside plasma membranes can timely meet requirements of various reactions in cells so as to maintain normal physiological activities of the cells, and thus, the action of postponing aging of the fruits is achieved. According to the method, the problem that aging, softening and physiological diseases of the fruits are aggravated due to the fact that the tissue of the fruits is relatively low in calcium content frequently, cellular functions of the fruits are weakened, the tissue is prone to aging or necrosis, and the degradation of the cell walls is accelerated is solved.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of agricultural products, in particular to a calcium-spraying fresh-keeping method for processing agricultural products. Background technique [0002] Many physiological diseases are associated with low calcium content in fruit tissues. When calcium is lacking, the function of fruit cells is weakened, the tissues are prone to aging or necrosis, and the degradation of cell walls is accelerated, thus aggravating the ripening, aging, softening and physiological diseases of fruits. [0003] The calcium content in the fruit tissue is related to the respiratory intensity and ethylene release of the fruit after picking. Calcium delays the aging and ripening of the fruit by inhibiting respiration and ethylene production. Calcium treatment after picking can reduce the respiration intensity of the fruit, inhibit the release of ethylene and the degradation of the cell wall, thereby delaying the aging ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a calcium-spraying fresh-keeping method for agricultural product processing and its application method, which solves the problem that often due to the low calcium content in fruit tissue, the function of fruit cells is weakened, the tissue is prone to aging or necrosis, and the cell wall is degraded. Accelerated, exacerbated the problems of fruit ripening, aging, softening and physiological diseases
