不同包装方式对曲拉贮藏过程中品质变化的影响

Effect of different package methods on quality changes of Qula during storage

  • 摘要: 为了选择适合曲拉的包装方式,减少其贮藏期间因品质劣变而造成的经济损失,本研究采用真空避光、真空非避光、非真空避光和非真空非避光4种包装方式,室温贮藏6个月,每月同一时间取样对其进行感官评价以及滴定酸度、过氧化氢值(POV)和硫代苯巴比妥酸反应底物值(TBARS)的测定。结果表明,经过6个月的贮藏后,非真空非避光包装方式的曲拉POV值比真空避光、非真空避光和真空非避光方式极显著地上升了0.54、0.28、0.11g/100g(p<0.01),且感官品质极显著劣于其它包装方式(p<0.01)。研究表明,真空避光、真空非避光和非真空避光包装方式均可有效延缓曲拉贮藏期间的品质劣变,并且,非真空避光和真空非避光包装方式之间不具有显著性。考虑到牧区真空条件有限以及综合经济因素,非真空避光包装方式适合在牧区推广应用。 

     

    Abstract: This research was conducted to explore the optimal package methods for Qula and reduce the economic losses caused by Qula quality deterioration during storage. Qula was stored in four types of packages, such as dark storages with or without vacuum and non- dark storages with or without vacuum.The samples were stored for6 months, then the sensory quality, titratable acidity, POV, TBARS were measured in every month during the storage.The results showed that POV of Qula in non- dark storage without vacuum package significantly increased than dark storage with vacuum, dark storage without vacuum and non- dark storage with vacuum for 0.54, 0.28, 0.11 g /100g ( p < 0.01) , and sensory quality of Qula in non- dark storage without vacuum package significantly lower than other ways after stored for 6 months. The study showed that dark storage with vacuum, dark storage without vacuum and non- dark storage with vacuum could effectively delay the quality deteriorated of Qula, furthermore there was no significance between packages of dark storage without vacuum and non- dark storage with vacuum.Considering of the limited condition in pastoral and the economic factors, package of dark storage without vacuum is more suitable for the application in the pastoral areas.
