Description

Inhibitor for preventing browning of cut vegetable

Technical field

The invention belongs to agent keeping vegetable fresh, particularly a kind of inhibitor for preventing browning of cut vegetable.

Background technology

The cutting vegetables claim fresh cut vegetables, recuperated vegetable, minimum (lacking) vegetable for processing etc. again, be classified fresh vegetables, put in order, select, after the series of processes such as cleaning, cutting, fresh-keeping, packing, be encapsulated in the soft bag or with the directly edible or catering trade use of the outer coating plastic film of plastic disk splendid attire for the consumer.The foundation of China various places vegetables home-delivery center in recent years is for the great development of cutting vegetables provides advantage.Along with living standard improves, vegetables increase year by year in the occupation rate of market of China in cutting.The cutting vegetables are as the fresh goods of slight processing, and also there are many problems in its Quality Control Technology, and brown stain is one of obstacle the most common in the processing of cutting vegetables.Different with complete vegetables, the cutting vegetables are because of handling through peeling, cutting, aldehydes matter under aerobic conditions through polyphenol oxidase catalyzed generation black polymer.The main chemical method that adopts of the control of brown stain at present commonly used press down brown dose sulphite, ascorbic acid etc. is arranged.Sulphite is mainly lived by inhibitory enzyme and is stoped brown stain to produce, and have bleachability concurrently, but sulphite has carcinogenic usefulness, destroys vitamin, produces offending olfactory and foul smell, and China's related food rules and regulations residual quantity must not surpass 10mg/kg at present.The principle of ascorbic acid etc. is to reduce the oxygen content of system by the autoxidation of the reducing agent that adds, if oxygen content height then act on little in tissue or the packing.

Summary of the invention

Technical problem to be solved by this invention is: a kind of inhibitor for preventing browning of cut vegetable is provided.

Technical scheme of the present invention is:

A kind of inhibitor for preventing browning of cut vegetable is characterized in that: it includes following component:
