摘要: 本实验以‘金冠’苹果为试材,研究了近冰温冷藏对果实贮藏品质和抗氧化能力的影响。确定了‘金冠’苹果的近冰温为(-1.7±0.2)℃。与0?℃贮藏相比,近冰温贮藏可以显著抑制苹果果实的呼吸强度和乙烯释放速率(P<0.05),推迟呼吸高峰出现时间,保持果实表面色泽,保持较高的可溶性固形物、可滴定酸质量分数和总酚、总黄酮含量及抗氧化能力,减缓丙二醛的积累和细胞膜透性的增加。这些结果表明,近冰温贮藏可以提高‘金冠’苹果的贮藏品质,是一种有效的贮藏保鲜方法。本实验结果为近冰温贮藏技术在苹果贮藏保鲜的应用提供参考依据。

Abstract: This study was implemented to investigate the effect of near freezing temperature (NFT) storage on the postharvest quality and antioxidant activity of ‘Golden Delicious’ apple fruit. NFT was set to be (-1.7 ± 0.2) ℃. Compared with storage at 0 ℃, NFT storage suppressed ethylene production and respiration rate, delayed the appearance of respiration peak, and maintained fruit color, higher soluble solids and titratable acid contents. In addition, NFT storage maintained higher levels of total phenols, and total flavonoids as well as higher antioxidant capacity. NFT storage retarded the increase of membrane permeability and malondialdehyde (MDA) content. Based on the results above, NFT storage should be recommended for improving the storage quality and antioxidant capacity of ‘Golden Delicious’ apple. This research provided a reference for the application of NFT storage in apple fruit storage.

Key words: near freezing temperature storage, ‘Golden Delicious’ apple, storage quality
