Abstract: The effects of hot-water alone or in combination of Ca2+ on senescence-related metabolism of ‘Dongzao’ jujube ( Zizyphus jujuba Mill. ) fruit were investigated during shelf-life. Jujube fruit were immersed in hot-water at 50-55℃ for 6 - 8 min. Hot-water treatment could remarkably retard the increases inrelative electric conductivity, malondialdehyde (MDA) content, browning index, activities of polyphenol oxidase, exo2PG and endo-PG, and prolong the shelf-life with higher fruit firmness. The addition of 1% CaCl2 into the hot-water enhanced the beneficial effects, but did not much affected polyphenol oxidase activity and browning index.
