Abstract

The invention relates to a fresh keeping agent for fresh cherimoya fruits and a use method of the fresh keeping agent. The fresh keeping agent comprises the following components in percentage by mass: 0.5-1.5% of citric acid, 4-8% of a fresh ginger extract, 5-12% of an argy wormwood leaf extract, 0.2-0.8% of garlic powder, 1-2% of hydroxylated chitosan and the balance of distilled water. The use method of the fresh keeping agent disclosed by the invention comprises the following steps of macerating the harvested fresh cherimoya fruits which are free from diseases and insect pests and are 80-90% in maturity in the fresh keeping agent for 20-30min, taking out the macerated fresh cherimoya fruits, draining the taken-out fresh cherimoya fruits, then putting the drained fresh cherimoya fruits in a freezer with the temperature being 10-15 DEG C and the relative humidity being 70-85%, and performing cold storage. According to the fresh keeping agent and the use method thereof disclosed by the invention, the technical problem of effectively keeping the fresh cherimoya fruits fresh is solved, the quality guarantee period of cherimoya is prolonged, and the industrialized development of the cherimoya sold to a distant place is promoted.

Description

technical field [0001] The invention relates to the technical field of fruit fresh-keeping, in particular to a fresh-keeping agent for fresh custard apples and a preparation method thereof. Background technique [0002] The custard apple is native to the tropical land of America and is widely distributed in the tropics and warmer subtropics. The lychee skin is similar to foreign products, so it is called custard apple, and because the ripe fruit is light green and yellow, the appearance is protruded by polygonal little finger-sized verrucous, just like the head of a Buddha, so there are "Buddha head fruit", "Buddha head fruit" and "Buddha head fruit".
