Abstract

The invention belongs to the technical field of fruit storage, and particularly relates to a fresh keeping method of pomelos. A fresh keeping agent is applied to the surfaces of the pomelos, then fresh-keeping gas is inflated into a storage room, so that controlled-atmosphere fresh keeping of the pomelos is realized; and the fresh keeping agent is prepared from the following raw materials of pomelo peel, pomelo leaves, chitosan, agar, phytic acid and ethyl acetate; and the fresh keeping gas consists of oxygen, carbon dioxide, ozone and nitrogen. According to the fresh keeping method, the fresh-keeping storage time of falling pomelos is greatly prolonged, the pomelos can be subjected to fresh keeping for 5-6 months, and the problem that the pomelos are difficult to store for a long time issolved.

Description

【Technical field】 [0001] The invention relates to the technical field of fruit storage, in particular to a fresh-keeping method for pomelo. 【Background technique】 [0002] Pomelo is the mature fruit of pomelo, a plant of Rutaceae, which is produced in southern my country such as Fujian, Jiangxi, Guangdong, and Guangxi.
