The effects of short-term anoxia exposure for 16h on physicochemical changes of 'Phulae' pineapple fruit stored at ambient temperature (25±2°C) were investigated. The respiratory rate of the fruit was induced by the anoxia treatment. However, it retarded the increase in moisture loss and maintained both flesh and pulp colour by inhibiting polyphenol oxidase (PPO) activity of the both tissues. The anoxia exposure delayed the increase in total sugar content and enhanced total ascorbic acid content during storage. The half-cut pineapple fruit showed that the anoxia exposure completely inhibited internal transparency of the flesh tissue adjacent to core during the storage. In conclusion, the short-term anoxia exposure for 16h maintained postharvest quality, retarded physiological disorder and enhanced nutritional values of the pineapple fruit stored at ambient temperature (25±2°C).
研究了短期缺氧暴露16小时对室温（25±2°C）下贮藏的‘Phulae’菠萝果实理化变化的影响。缺氧处理诱导了果实的呼吸速率。然而，它减缓了水分损失的增加，并通过抑制果肉和果心组织的多酚氧化酶（PPO）活性来维持果肉和果心的颜色。缺氧暴露延缓了贮藏期间总糖含量的增加，并提高了总抗坏血酸含量。对半切开的菠萝果实表明，缺氧暴露在贮藏期间完全抑制了靠近果心的果肉组织的内部透明度。总之，短期缺氧暴露16小时可保持室温（25±2°C）下贮藏的菠萝果实的采后品质，延缓生理失调并提高营养价值。
