Abstract

The invention discloses a freshness preservation method of grapes. The freshness preservation method of the grapes comprises the following steps: separately milling 0.4-0.8 part by weight of natural mineral powder, 0.2-0.6 part by weight of pine needle powder and 0.1-0.3 part by weight of silver powder by using a ball mill, carrying out sieving by using a 500-700-mesh sieve, and carrying out uniform mixing; adding 1.2-2.5 parts by weight of LDPE, and carrying out uniform mixing; and then, carrying out injection molding or blow molding so as to obtain a freshness preservation material. The freshness preservation method of the grapes has excellent bacterium-resisting and freshness-preserving performance.

Description

technical field [0001] The invention relates to the technical field of fruit preservation, in particular to a grape preservation method. Background technique [0002] Grape is a woody vine of the genus Vitis vinifera, with cylindrical branchlets, longitudinal ribs, glabrous or sparsely pilose, oval leaves, dense or scattered panicles, well-developed base branches, spherical or oval fruit, flowering period April-May, fruiting period August-September. Grapes are one of the oldest fruit tree species in the world. Plant fossils of grapes have been found in Tertiary strata, indicating that they were all over Europe, Asia and Greenland at that time. Grapes are native to West Asia and are cultivated all over the world. About 95% of grapes around the world are concentrated in the northern hemisphere. [0003] Grapes will basically lose their commerciality after being stored for 1-2 days at room temperature, seriously affecting the sales of grapes. Therefore, the post-harvest prese...
