中文摘要:
      目的 为探究气调包装对建水草芽贮藏品质的影响。方法 采用低氧气调(MAP1)、高氧气调(MAP2)和高氧结合高二氧化碳(MAP3)处理新鲜建水草芽,在4 ℃条件下贮藏20 d,观测其品质变化。结果 与空白对照组相比,MAP1组前期可以有效维持草芽的品质,后期由于草芽进行无氧呼吸,反而会加速其品质劣变。高氧气调组能够有效保持草芽的品质,且MAP3组效果更佳,能够维持较低的质量损失率和硬度,保持较高的Vc含量和L*值,且感官性状评价最好。主成分分析(PCA)提取出2个主成分,累计方差贡献率为87.67%,能较好地解释草芽贮藏品质的信息。L*值、Vc含量、硬度、质量损失率和二氧化碳含量对草芽贮藏期品质的影响较大。PCA分析进一步证明高氧、高二氧化碳气调处理有助于草芽贮藏品质的稳定。结论 气调包装能够有效地提高建水草芽的贮藏品质,延长贮藏期,其中高氧结合高二氧化碳气调处理的保鲜效果最好。
英文摘要:
      The work aims to explore the effect of modified atmosphere packaging on the storage quality of Jianshui cattail. Fresh Jianshu cattail was treated with low oxygen atmosphere (MAP1), high oxygen atmosphere (MAP2) and high oxygen combined with high carbon dioxide atmosphere (MAP3). The quality changes of cattail were observed during storage for 20 days at 4 ℃. Compared with the blank control group, MAP1 group could effectively maintain the quality of cattail in the early stage, but accelerated the quality deterioration in the later stage due to the anaerobic respiration of cattail. High oxygen atmosphere group could effectively maintain the quality of cattail, while MAP3 group had better effect, which could maintain a lower weight loss rate and hardness and keep a higher value of Vc and L, and had the best sensory traits evaluation results. In PCA analysis, two main components were extracted, and the cumulative pigment contribution rate was 87.67%, which could better explain the information about the storage quality of cattail. L, Vc, hardness, weightlessness rate and carbon dioxide had great effects on the quality of cattail during storage. PCA analysis further verified that the combination of high oxygen and high carbon dioxide could help to stabilize the quality of cattail during storage. Modified atmosphere packaging can effectively improve the storage quality of Jianshui cattail, prolong the storage period, and the combination of high oxygen and high carbon dioxide has the best fresh-keeping effect.
