Color protection and freshness-keeping technology of Agaricus bisporus during modified atmosphere storage

With Agaricus bisporus as experiment material, this paper mainly discussed the effect of different chemical fresh-keeping substances on keeping quality of Agaricus bisporus. The optimum proportion of different fresh-keeping substance was obtained through orthogonal experiment. The results show that the best browning inhibitor and concentration for storaged Agaricus bisporus are: 0.1% sodium sulfite, 0.06%～0.10% ascorbic acid and 0.8～2.6 mmol/L cysteine. The best constitute and proportion for fresh-keeping substance are: 12 mmol/L cysteine, 0.05% ascorbic acid, 0.15% sodium sulfite and soak time 8 minutes.
