Abstract: After picking respiration of strawberries is exuberant.It is easy to lose the goods value beacause of wither.Strawberries can lengthen goods time and maintenance quality after processing with coating reagent which main body is nisin.According to research proportion of sodium alginate and polyethylene glycol,the result is that, the best proportion is 300mg/l nisin,500mg/l natamycin,1% sodium alginate, 1% polyethylene glycol,10% ethyl alcohol.This coating reagent can cover pore of epidermis, prevent water evaporatesing, prevent wither,prevent invasion of microorganism, prevents the corrupt deterioration and have the miniature gas adjustmentthe function.
