Method for fresh-keeping of sunagowase peaches with compound fructus ligustri lucidi extracted liquid

Abstract

The invention discloses a method for fresh-keeping of sunagowase peaches with compound fructus ligustri lucidi extracted liquid. The method includes: selecting sunagowase peaches with a growing periodof 60-70d and fruit stalks for standby use; mixing fructus ligustri lucidi, clove and licorice in proportion to obtain mixed herbal medicines, adding water, performing soaking and boiling, finally maintaining that the weight of the extracted liquid is 20-40 times that of the mixed herbal medicines, and conducting cooling for standby use; soaking the sunagowase peaches in the compound fructus ligustri lucidi extracted liquid, and conducting ventilating and airing; and putting the treated sunagowase peaches into a PE film for storage. The fresh-keeping method provided by the invention can makethe storage time of sunagowase peaches reach 15 days, also ensures that the sunagowase peaches are still fresh, and the rate of intact fruits can reach 90% or more, the storage time is prolonged by 7-12 days compared with untreated fruits, the rotting rate is reduced to 10% or below, and good quality of the fruits is maintained. The compound fructus ligustri lucidi extracted liquid adopted by theinvention is prepared from edible and medicinal raw materials fructus ligustri lucidi, clove and licorice, is safe and non-toxic, and is poisonless and harmless to the human body and environment.

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...
