Abstract
Softening is one of the crucial factors causing the deterioration of postharvest fruit quality. In this study, the effects of konjac glucomannan/low-acyl gellan gum/microcapsule of thymol (TKL) coating on the storage characteristics, the ultrastructure of cell wall and transcription expression of pectin-related metabolism of blueberries fruits during low-temperature storage were investigated. TKL coating suppressed the expression of pectin-related enzymes disassembly (VaPE2, VaPE3, VaPG3, VaPL2 and Vaβ-Gal2), reduced the activity of cell wall polysaccharide degrading enzymes (PG, PE, PL, β-Gal, α-Man, α-Af, Xth, β-Xyl, Cx, β-Glu), maintained the normal morphological structure and stability of cell wall, and prolonged the shelf life of blueberries fruits. Overall, TKL is a promising coating that can effectively maintain the firmness, inhibit the postharvest softening and prolong the shelf life of the blueberries during storage period.
