托盘和真空包装对冷却羊肉品质的影响

Effects of pallet and vacuum packaging on quality of chilled mutton

  • 摘要: 为研究托盘和真空包装对冷却羊肉品质的影响,本实验采用PA/CPP、PA/PE两种真空包装材料和普通托盘在真空度0.08 MPa条件下分别对冷却羊肉进行包装,4℃条件贮藏20 d。通过对其储存过程中汁液流失率、p H、挥发性盐基氮值、色泽、菌落总数进行分析,揭示出两种包装方式对冷却羊肉品质影响的差异性。结果表明:在贮藏过程中,真空包装的汁液流失率显著高于普通托盘包装,但普通托盘包装的菌落总数和挥发性盐基氮值显著高于真空包装(p>0.05),且保质期短于真空包装。真空包装组中,PA/CPP组在贮藏过程中汁液流失率最低,但与PA/PE组差异不显著(p>0.05)。真空包装可以有效延长冷鲜肉的保质期,但PA/CPP和PA/PE对冷却羊肉品质的影响差异不显著(p>0.05)。 

     

    Abstract: The aim of this study was to investigate the effects of pallet and vacuum packaging on chilled meat's quality. In this study, chilled mutton was packaged in Nylon / chlorinated- polypropylene( PA / CPP), Nylon /polyethylene(PA/PE) vacuum packaging materials and general-purpose pallet,respectively. Samples was stored for 20 days at 4 ℃,vacuum degree of 0.08 MPa. Drip loss rate,p H,total volatile basic nitrogen(TVB-N),color,total viable counts were determined during the storage period. The results showed that compared with pallet packaging,the vacuum-packed samples had the significant higher drip loss during the storage period.Total microbial counts and TVB-N values of ordinary pallet packaging were higher than vacuum packaging significantly(p>0.05). Among two vacuum-packed groups,PA/CPP group had the lower drip loss,but the difference between PA/PE group was not significant. Therefore,vacuum packaging could effectively extended the shelf-life,and the influences of the two packaging materials PA/CPP and PA/PE on chilled mutton quality were not significant(p>0.05).
