Description

technical field [0001] The invention belongs to the technical field of fruit preservation, and in particular relates to a method for preserving the freshness of sandy early-growing peaches by using compound privet lucidum extract. Background technique [0002] There are many methods of fruit storage and preservation, such as refrigeration, controlled atmosphere storage, heat treatment technology, fungicide treatment, radiation treatment, decompression treatment, coating technology, etc. These preservation techniques and methods are too single and lack comprehensive control technology; Excessive reliance on chemical reagents, high-efficiency, non-toxic, and non-polluting fresh-keeping technologies are still relatively lacking; existing technical solutions are (1) cleaning treatment; (2) pre-cooling treatment; (3) chemical fungicide treatment; (4) chitosan Sugar coating treatment; (5) postharvest heat treatment; (6) low temperature storage and transportation. Although this me...
