Effect of composite coating of konjac glucomannan with green tea polyphenols on antioxidant activity and shelf-life of post-harvest passion fruit

Abstract: In this study, the effect of konjac glucomannan (KGM) and green tea polyphenols (GTP) on the preservation quality of passion fruit was explored by using different GTP (0.1%, 0.2%, and 0.3%) in combination with 0.5% KGM. Quality indexes, physicochemical parameters, and antioxidant enzyme activities of passion fruit were measured every three days during storage. Overall, the results revealed that the 0.2% GTP/0.5% KGM composite coating prevailed as the best preservation group, effectively delaying the increase o… Show more
