摘要: 本文研究了冬枣在0±1℃,大气压力分别为101.325、81.06、50.663、20.265kPa的贮藏条件下的生理生化变化,同时初步筛选出较适宜的压力范围。结果表明, 减压贮藏显著降低了冬枣VC的损失,抑制了可溶性固形物含量的增加和果肉硬度的下降,显著抑制了PPO活性,降低了果肉组织相对电导率和果实褐变率,从而延缓了果实的成熟衰老。

Abstract: In this paper, the physiological and biochemical changes of DongZao under the conditions of low pressure werestudied.The Optimum storage pressures tested for jujube fruits were sifted. Results of the study could be expressed as follows:Hypobaric storage slowed down markedly the loss rate of VC (at 0.5% level), inhibited the decrease of firmness and the increaseof TSS content significantly at 20.265kPa (at 1% level), inhibited the PPO activity and slowed down the relative conductivityand the browning rate of jujube fruits.

Key words: Chinese jujube Dongzao, hypobaric storage, physiological and biochemical indexes
