摘要: The effect of vacuum impregnation with ascorbic acid (AA) and calcium ascorbate (CaA) on enzymatic browning of fresh-cut potatoes was investigated. Results showed that vacuum impregnation (VI) with AA-CaA treatment for 2 min had a significant anti-browning effect. VI treatment not only maintained cell membrane integrity, inhibited the key enzyme activities of polyphenol oxidase, peroxidase and phenylalanine ammonia-lyase but also retarded generation of phenolic substrate, particularly chlorogenic acid. Meanwhile, VI promoted AA-CaA solution to infiltrate into potato tissue and delayed loss of ascorbic acid. In conclusion, VI treatment was more efficient for preventing browning with a shorter processing time of 2 min compared to traditional impregnation under atmospheric pressure and could be used as a promising method to inhibit browning of fresh-cut potatoes.
