Abstract:
Taking ‘Xiahei’ grapes as experiment materials,the unpackaged and LDPE film packaged grapes were set as control groups,and the preservation effect of SO2control release packing(K-type),with and without ethylene absorbent were comparatively studied.During the storage,the headspace concentrations,appearance quality,water loss,stem browning,solidity,TSS,TA,and the vitamin C content were tested and analyzed in a two days interval,in order to extend the shelf-life of ‘Xiahei’ grape at room temperature (25±1)℃.The results showed that SO2 control release packaging (K-style) could form a stable atmosphere suitable for grape preservation and inhibit the growth of pathogenic bacteria of grape.After 8 days storage at room temperature,the grapes that unpackaged and LDPE film packaged were browning and rotten fruit seriously,while the grapes packaged in the K-type storage bags and ethylene absorbent group packaging grape browning degree were 1 and 2 respectively,rotten fruit rate were 1.13% and 3.56%,the grapes quality was good and tasted well,fresh-keeping effect was obvious.
