Abstract

The invention discloses a kiwi fruit preservative and a using method thereof. The kiwi fruit preservative is prepared from naphthylacetic acid aqueous solution and assistant, wherein the assistant is one of oxalic acid, calcium nitrate and salicylic acid, and the concentrations of naphthylacetic acid, oxalic acid, calcium nitrate and salicylic acid in aqueous solution are 10mg / L, 250-450mg / L, 1000-3000mg / L and 150-300mg / L respectively. The using method comprises the following steps of uniformly spraying preservative on leaf surfaces and kiwi fruit surfaces firstly 30-40 days before picking until dripping, spraying every seven days, spraying for three times, packaging into a polyethylene bag after picking without sealing, and storing at normal temperature. After the preservative is used according to the using method, the rotting rate of the picked kiwi fruits can be reduced, the storage time of the picked kiwi fruits can be prolonged, the flavor and the quality of the fruits are improved, and the kiwi fruit preservative has high efficiency and low price, has no side and toxic effects, is environmental friendly, is convenient to operate, and is convenient for large-scale popularization and application.

Description

Technical field [0001] The present invention is a fruit preservation technology field, which involves a kind of kiwi fruit preservation agent and its usage. Background technique [0002] Kiwi is the family of kiwi ( Actinidiaceae ) Kiwi genus ( Actinidia ) The perennial vine plant, male and female, is an important fruit resource.There are 66 species of kiwi in the world, of which 62 are native to China. Among them, delicious kiwi, Chinese kiwi, hair kiwi and soft jujube kiwi with important commercial economic value.Kiwi is a typical breathing jump, which is extremely sensitive to temperature and ethylene. After the softening process is rapid, the skin is thin, the diseased is frequent, and it is easy to rot.Ten days rotten, half a month is half bad ".Therefore, experts and scholars at home and abroad try to soften aging and rotten in various ways to inhibit kiwi fruits, thereby extending the storage period of fruit and increasing their commodity rate.my country's kiwi production ...
