Abstract: Using the plateau characteristic vegetable of red cabbage as experimental test material,this study explored the effect of pressurized argon preservation treatment on the storage quality of fresh-cut purple cabbage,and then optimized the preservation process of pressurized argon of fresh-cut red cabbage. Moreover,by single factor and Box-Behnken response surface methodology,the multiple regression model of weight loss rate of fresh-cut red cabbage was established to optimize the preservation process of pressurized argon of fresh-cut red cabbage. The results showed that the best conditions were the pressure argon treatment pressure,1.0 MPa,pressure holding time,61 min,pressure time 99 s,and withdrawal pressure time 148 s,respectively. After 20 d storage,the weight loss rate of fresh-cut red cabbage was 3.57%,and compared with the weight loss rate measured under non-pressure treatment,it decreased by 42.0%. The effect of retaining freshness was obviously improved.
