Study on pods fibrosis delaying of postharvest common bean by chitosan treatment
摘要
Abstract
To explore the effects of chitosan coating treatment on pods fibrosis of postharvest beans,the common bean pods were dipped into the chitosan solutions of 1,5 and 10 g/L,respectively.The results indicated that the increase of cutting velocity for crude fibre were inhibited when the common bean pods were treated with chitosan.After eight days storage,the cutting force and the fiber content of the common bean pots with chitosan treatment was 12.5% and 7.4%,respectively,which were both lower than the controls.The reason was that the activity increases of peroxidase（POD）,polyphenol（PPO） and phenylalanin ammonialyase（PAL） were inhibited in the chitosan treated pods of common beans,which delays the process of fibre synthesis of common bean pods.After eight days storage,the activities of peroxidase（POD）,polyphenol（PPO） and phenylalanin ammonialyase（PAL） in the common bean pots treated with 10 g/L chitosan was 21.8%,80.0% and 31.8%,respectively,which were lower than those without chitosan treatment.The results showed that the application of 10 g/L chitasan treatment was more effective than other treatments.关键词
