Abstract

The invention discloses a method for inhibiting browning of konjac and belongs to the technical field of konjac processing. The method for inhibiting browning of konjac comprises the following steps: (1) selection of konjac; (2) preparation of a color fixative; (3) spraying; (4) airing; (5) coating with a preservative film; and (6) boxing. According to the method, optimal process conditions are selected; by adopting a combined mode of spraying the specially developed color fixative and coating with the preservative film, browning of the konjac can be effectively inhibited; and harmful solvents or additives are not added in the preparation process of the color fixative, and the color fixative is a natural nontoxic solution, so that the color fixative has a good effect when used for inhibiting browning of the konjac, is nontoxic and harmless and can be safely used.

Description

technical field [0001] The invention relates to the technical field of konjac processing, in particular to a method for inhibiting konjac browning.
