Effects of Different Chitosan Oligosaccharides Treatment Methods on Quality During Storage of'Xizhou Mi No.25'Melons
摘要
Abstract
To investigate the effects of two treatment methods preharvest and postharvest chitosan oligosaccharides(COS)on the storage quality of melon fruit,the melon cultivar'Xizhou Mi No.25'was selected as experimental material.Melon fruits were subjected to 100 mg/L COS treatments,including single pre-harvest spraying,single post-harvest soaking,and their combined treatment.The results showed that chitosan oligosaccharide(COS)treatment maintained flesh firmness and soluble solids content of muskmelon during storage,reduced weight loss rate,suppressed ethylene release rate and respiration rate,and delayed fruit decay.It also elevated the activities of β-1,3-glucanase,chitinase and phenylalanine ammonia-lyase(PAL),promoted total phenols accumulation,and enhanced fruit stress-resistance.Among all treatments,the combined treatment of pre-harvest spraying plus post-harvest soaking exhibited the optimal preservation performance.On the 14th day of storage,flesh firmness in the combined treatment was 14.8%higher,while the peak value of ethylene release rate was decreased by 23.1%,both showing significant differences compared with the control(CK).Moreover,highly significant differences were observed for defense-enzyme activities(β-1,3-glucanase,chitinase,PAL)and total phenolic content between the combined treatment and CK.At the 35th day of storage,the fruit decay rate was reduced by approximately 10%,and the decay index decreased by more than 27%relative to CK.This study provides a reference for the application of COS in field production and post-harvest preservation of melon fruit.关键词
