Abstract

The invention discloses a compound preservative for fruits and a preparation method of the compound preservative. The compound preservative is mainly used for keeping freshness of the fruits such as bananas and dragon fruits and belongs to the technical field of freshness keeping of the fruits. The compound preservative is prepared from the following raw materials in percentage by mass: 3 to 40 percent of prochloraz, 0.01 to 10 percent of plant essential oil, 35 to 90 percent of vegetable oil and derivatives thereof, 5 to 20 percent of an emulsifier and 1 to 5 percent of glycerol, wherein the total amount of the raw materials is 100 percent. The compound preservative for the fruits, disclosed by the invention, has the advantages that storage diseases, in particular to banana anthracnose, crown rot, spike rot and other diseases, of the fruits can be effectively prevented and controlled; in addition, the ripening of the fruits can be delayed, the resistance of the fruits is improved, storage period and shelf life of the fruits are prolonged and the post-harvest loss is reduced.

Description

technical field [0001] The present invention relates to a compound preservative for fruit and a preparation method thereof, in particular to a compound preservative comprising prochloraz, plant essential oil, vegetable oil and its derivatives and a preparation method thereof, which is mainly used for the preservation of fruits such as bananas and pitayas The postharvest preservation belongs to the technical field of fruit preservation. Background technique [0002] During the process of planting, picking, storage, processing and consumption of fruits and vegetables, due to the infection of pathogenic microorganisms, they are easily spoiled and deteriorated, especially the tropical fruits in the south. Waste of resources and economic loss. [0003] Banana is a climacteric fruit. Bananas harvested in midsummer, high temperature and high humidity are easy to yellow and ripen or even rot. Postharvest diseases of bananas mainly include anthracnose and shaft rot. Banana anthrac...
