The applications of organophosphorus hydrolase,tween,ozone and combination treatments to the organophosphorus pesticides degradation in baby cabbage were conducted.Their impact on nutrition,color and texture elements of vegetable was analyzed.The result showed that tween combined ozone and tween combined enzyme displayed visible synergistic effect.It was most effective by combination of tween plus ozone with 65%~81% degradation.Washing by tween combined enzyme can reduced four kinds of organophosphorus pesticides residue such as dichlorovos,chlorpyrifos,malathion and methyl-parathion to 65%~99%.And it also had 40% degradation in systemic insecticides such as methamidophos,acephate,omethoate.After degradation,the value of L*,a*,b* in vegetable surface were almost constant.The content of ascorbic acid in the baby cabbage maintained more than 80%.Overall,the baby cabbage kept the good sensory quality.
