KimaCell®HPMC K100M FG is a cellulose derivative, HPMC has excellent stability, dispersibility, film-forming property and antibacterial function, and its low-concentration solution has good selective air permeability. HPMC coating treatment has a fresh-keeping effect on fruits such as citrus, plums and grapes, which delays the decline in storage quality. However, there is no report on the effect of HPMC coating treatment on postharvest physiology, quality and antioxidant activity of fruit and its regulation mechanism. Based on the effects of different concentrations of HPMC coating on the quality and sensory parameters of red bayberry fruit after refrigeration, the relationship between HPMC coating to maintain fruit storage quality and antioxidant activity was discussed from the postharvest physiology of the fruit and the expression of key enzyme genes for anthocyanin synthesis. mechanism.

KimaCell® HPMC K100M FG coating treatment can significantly inhibit the increase of the rot rate of fruit during storage at 1℃, reduce the respiration rate and ethylene release, reduce the accumulation of MDA and inhibit the increase of relative conductivity, thereby delaying the postharvest senescence process of the fruit and making the fruit in the High TSS and TA contents remained after storage. However, considering that 10% HPMC film treatment may cause anaerobic respiration to reduce the sensory quality of fruit, it can be considered that 5% HPMC film has the best effect on fruit preservation.
5% HPMC coating treatment can effectively induce the expression of PA31 and CHS genes during the storage of fruit, thereby significantly promoting the synthesis of fruit anthocyanin monomer substances, delaying the decline of fruit free radical scavenging ability and reducing power, and making the fruit more stable during storage. High antioxidant activity was maintained during this period.
