Abstract

The invention relates to the field of preservative technology, and especially to an application method of a film coating preservative of lotus root. The film coating preservative of lotus root includes sucrose ester and chitosan. The application method includes mixing the film coating preservative of lotus root and tap-water in a volume ratio of 1-1.2:1500-1900. The volume ratio of the film coating preservative of lotus root to the tap-water is 1.1:1700 when the film coating preservative of lotus root is used in spring and autumn, the volume ratio is 1:1800 in summer, and the volume ratio is 1.2:1900 in winter. The preservative is simple in configuration and safe in usage, can inhibit the respiration and the moisture evaporation of the fruit and vegetable to make the fruit and vegetable be in dormancy, so that the aging of the fruit and vegetable can be deferred.

Description

technical field [0001] The invention relates to the technical field of antistaling agents, in particular to a method for using a lotus root coating antistaling agent.
