Abstract

The invention provides a coated-type ginseng fresh-keeping film, and belongs to the technical field of agriculture. The invention assists in solving problems of ginseng fresh-keeping difficulty after harvesting, ginseng storage and transportation difficulty, ginseng water content loss, and ginseng effective component loss currently. According to the ginseng fresh-keeping film provided by the invention, corn starch is adopted as a main raw material; food raw materials are adopted as a plasticizing agent and a thickening agent; and natural antibacterial active substances are used for improving antibacterial and fresh-keeping capacities of the edible film. With a coating method, the film is coated on the surfaces of ginseng, such that water content loss can be reduced, respiration effect can be inhibited, and microbial growth can be inhibited. With the film provided by the invention, color, taste, and shape of ginseng after 180 days of preservation are not substantially changed, and contents of components such as total saponin and total sugar are not substantially reduced.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and relates to a ginseng fresh-keeping technology, in particular to a method and technology for fresh-keeping ginseng by using a coated edible fresh-keeping film. technical background [0002] Ginseng is a plant of the genus Panax in the family Araliaceae.
