Problems solved by technology

Among them, although mechanical refrigeration and controlled atmosphere storage have good effects, due to the large investment in the construction of cold storage and controlled atmosphere storage, the high cost of maintenance and operation, and the poor storage effect does not match the initial investment, they are popularized and applied in actual production. very few
However, chemical treatment and radiation treatment are prone to drug residues, and there are hidden dangers in safety. Therefore, it is imperative to explore new efficient and safe storage and preservation technologies for ginkgo.

Abstract

The invention discloses a ginkgo fruit composite preservative and a preservation method. The ginkgo fruit composite preservative comprises a film coating agent, an antibacterial agent and a fumigation agent, wherein each liter of the film coating agent comprises the following components in parts by weight: 10-15g of chitosan, 0.2-0.5g of nano-SiO2, 15-18g of glycerine and solvent, namely acetic acid in the volume concentration of 10%; each liter of the antibacterial agent comprises the following components in parts by weight: 0.1-0.5g of ginkgo exocarp ethanol extract and the solvent, namely water; each liter of the fumigation agent comprises the following gas components: 0.5-1.0mu L of 1-methyl cyclopropene and the balance of air. By using the composite preservative for treating ginkgo fruits, the mildew phenomenon of the ginkgo fruits during the storage period can be effectively inhibited, the problem of water loss of the ginkgo fruits can be simultaneously greatly reduced, the storage and preservation period of the ginkgo fruits can be prolonged to the greatest extent, the fruit hardening of the ginkgo fruits can be prevented and the occurrence of calcification phenomenon can be also prevented.

Description

technical field [0001] The invention belongs to the fresh-keeping storage technology of nut products, in particular to a ginkgo fruit fresh-keeping agent and a fresh-keeping treatment method of the ginkgo fruit. Background technique [0002] Ginkgo biloba L. is a perennial deciduous tree of the genus Ginkgo in the family Ginkgoaceae. Plants are called "living fossils". Ginkgo biloba has always been one of the favorite foods of the Chinese people, and it is also one of the more popular nuts in the world. According to statistics, my country's ginkgo export volume accounts for more than 90% of the international circulation. Ginkgo fruit is composed of fleshy outer testa, bony middle testa, membranous inner testa, endosperm and seed embryo rich in nutrients. Ginkgo used for preservation, processing and fresh consumption is mainly after removing the outer testa The seed nucleus of Ginkgo, commonly known as ginkgo, also known as ginkgo fruit, is rich in protein, amino acid, fat...
