Abstract

The invention discloses a grapefruit pickling and fresh-keeping composite treatment method and belongs to the technical field of fruit fresh keeping. The method particularly includes steps of: at 10-15 days before picking grapefruit fruits, spraying a pre-compound agent solution composed of water, CaCl2 and salicylic acid; randomly selecting the grapefruit fruits being free from mechanical injuryand pests, being uniform in size and being 80-90% matured, and picking the grapefruit fruits; placing the picked grapefruit fruits in a post-picking fresh-keeping agent solution composed of water, ascorbic acid, citric acid and water-soluble chitosan for 5-10 min, and naturally air-drying the grapefruit fruits; packaging the grapefruit fruits independently and storing the grapefruit fruits at roomtemperature. After the grapefruit fruits is stored for 35 days, rotting rate of the grapefruit fruits is 5% and complete commercial fruit ratio can reach more than 94%. The method can maintain the original quality of the grapefruit and prolong shelf life of the fruits.

Description

technical field [0001] The invention relates to the technical field of fruit preservation, in particular to a composite treatment method for grapefruit picking and preservation. Background technique [0002] Grapefruit (Citrus paradise Macf.) belongs to the genus Citrus of Rutaceae, one of the four major groups of citrus in the world. It is called grapefruit because of its habit of fruiting in clusters. Its flesh is tender, juicy and refreshing, with a slight aroma, slightly sour taste, and a slightly bitter taste in the juice, but the taste is comfortable, rich in vitamins and various minerals, etc. It has high economic value and medicinal value. During grapefruit picking and transportation, the epidermis is damaged, prone to mildew and diseased fruit, and is easy to infect, causing post-harvest diseases and rot, resulting in very serious fruit losses. [0003] Aiming at postharvest diseases of grapefruit, the commonly used grapefruit storage methods are mainly low-temper...
