Abstract

The invention discloses a method of inhibiting rot of blueberry fruits, which particularly includes steps of: selecting healthy blueberry fruits, which have uniform size and color and are free of diseases, pests and damage; washing the blueberry fruits in flowing water and soaking and washing the blueberry fruits in acidic electrolyzed water; processing the blueberry fruits with a composite film coating solution; draining the blueberry fruits, and packaging the blueberry fruits in polyethylene thin film bags, being 0.015 mm thick, in a modified atmosphere manner; and storing the blueberry fruits in a refrigerator at 4 DEG C. The blueberry fruits treated in the method can be stored for 25 days, so that problems of quality deterioration of the picked blueberry fruits due to rot of the fruitsduring storage and fresh-keeping process are solved, thereby prolonging the storage life of the blueberry fruits.

Description

technical field [0001] The invention relates to a method for preserving fruits and vegetables, in particular to a method for inhibiting blueberry fruit from rotting. Background technique [0002] Blueberry belongs to Rhododendronaceae Vaccinium plant, known as "Queen of Fruits" and "Fruit of Color Contact". Because of its high nutritional value and health benefits, it is popular all over the world, and it is one of the five healthy fruits recommended by the World Food and Agriculture Organization. However, the water content of blueberry fruit is high, the tissue is tender, the physiological metabolism is vigorous after harvest, and the aging is fast, and the fresh fruit is easy to lose water, shrink and rot. Fruit rot is the most prominent problem of postharvest quality deterioration of blueberries, which seriously affects the edible quality and commodity value of blueberries. Therefore, the research and development of effective blueberry fruit rot suppression methods and ...
