Abstract:The investigation was conducted to determine the efficacy of DSC as a browning inhibition agent of fresh-cut and canned Agaricus bisporus.DSC and other anti-browning agents as well as the new compound color fixative ware used in pretreatment and canned Agaricus bisporus.Residual activity of PPO and the browning degree(BD) were measured as performance figures.DSC played an important part in enzymatic browning inhibition,compared to other anti-browning agents such as phytic acid,citric acid and VC.The sliced Agaricus bisporuss pretreated with mixed liquor containing 0.2% citric acid,0.03% DSC,0.02% phytic acid,0.03% VC were effectively kept from enzymatic browning and then blanched.In addition,the products with DSC resulted in better performance than those with sodium metabisulphite as well as other anti-browning agents.The best compound color fixative of anti-browning agents in the cans was to be 0.03% DSC,phytic acid 0.02%,citric acid 0.1% and 0.3% CaCl2,which leaded to a similar effect of browning inhibition,as compared with 0.02% of sodium metabisulphite.In general,DSC proves to be able to take the place of sodium metabisulphite and act as a new safe and effective anti-browning agent used in canned Agaricus bisporuss.
