该试验研究了包装材料对鲜切菠萝贮藏品质的影响。采用自发气调袋包装鲜切菠萝，对照组选用普通菠萝保鲜袋，置于4 ℃低温贮藏。测评了鲜切菠萝感官评价，探究了包装袋气体成分变化、硬度、可溶性固形物（TSS）、可滴定酸（TA）、抗坏血酸（Vc）、丙二醛（MDA）、乙醇等各项指标。结果表明，与对照组相比，气调袋包装的鲜切菠萝在贮藏期间O2浓度保持在11.29%以上，CO2浓度保持在3.03%以下，贮藏12 d感官得分为9.67分，硬度下降11.17%，TSS下降19.44%，TA下降12.14%，Vc含量下降21.78%，有效缓解了鲜切菠萝各生理指标下降的趋势。与普通保鲜袋相比，气调袋抑制了菠萝MDA含量和乙醇含量的增加，普通袋MDA含量为3.52 μmol/g，而气调袋为2.99 μmol/g，缓解了鲜切菠萝的膜脂过氧化；普通袋乙醇含量高达615.9 μg/g，而气调袋乙醇含量仅为120.68 μg/g，大大减少了菠萝在贮藏期间无氧呼吸产生乙醇。因此，采用自发气调袋包装有效的保持了鲜切菠萝的品质，延长了鲜切菠萝的贮藏期，具有广阔的市场前景。

In this study, the influence of packaging materials on the storage quality of fresh-cut pineapple was examined. Fresh-cut fruit pineapple were packed in self-activated modified atmosphere bags (MAP) or normal commercially available fresh-keeping bags (the control group (CK)), before being stored at 4 ℃. The fresh cut pineapple samples were subjected to sensory evaluation, and the quality indices including the headspace gas composition, and the hardness, total soluble solids content (TSS), titratable acid (TA), ascorbic acid (Vc) content, malondialdehyde (MDA) content and ethanol content of the fruit samples were measured. The results showed that compared with the control group, the fresh-cut pineapple packed in MAP had an O2 concentration above 11.29% and CO2 concentration below 3.03% during the storage. On the 12th day of storage, the sensory score was 9.67, and the hardness, TSS, VC and TA decreased by 11.17% 19.44%, 12.14% and 21.78%, respectively, thereby alleviating effectively the decline of the physiological indices of fresh-cut pineapple. Compared with the normal fresh-keeping bag, the MAP inhibited the increases of MDA and ethanol contents in fresh-cut pineapple. The MDA content of the fruit in the normal bag was 3.52 μmol/g, whilst that for the MAP was 2.99 μmol/g (MAP alleviated effectively the membrane lipid peroxidation). The ethanol content of the fruit in the normal bag was 615.9 μg/g, whilst that for the MAP was only 120.68 μg/g (MAP reduced greatly the anaerobic respiration to produce ethanol in the fresh-cut pineapple during storage). Therefore, the self-activated MAP effectively maintained the quality of fresh-cut pineapple and prolonged its storage duration, thereby having a broad market prospect.
