摘　　要：研究乙烯-乙烯醇共聚物(EVOH)、聚乙烯(PE)和聚酰胺(PA)复合膜的阻隔性,并应用于冷鲜肉的包装,评估其货架期。对PE/EVOH/PE和PE/PA/EVOH/PA复合膜的阻隔性进行测定,并选用常用的PA/PE复合膜进行对照,对冷鲜肉进行真空包装。通过对菌落总数、p H值和汁液流失率等指标的测定来确定其对冷鲜肉货架期的影响。由PE/EVOH/PE和PE/PA/EVOH/PA复合膜包装的冷鲜肉货架期均可达到23 d,与PA/PE复合膜相比PE/EVOH/PE和PE/PA/EVOH/PA复合膜的汁液流失率也小。PE/EVOH/PE和PE/PA/EVOH/PA复合膜较PA/PE复合膜可显著延长冷鲜肉的货架期。The barrier properties of PA/PE, PE/EVOH/PE and PE/PA/EVOH/PA composite films were studied and the fi lms were applied to the chilled meat packaging. The total bacterial count, p H and drip loss of the chilled meat were tested to asseesd its shelf life. The results showed that the shelf life of chilled meat was packaged by PE/EVOH/PE and PE/PA/EVOH/PA composite fi lms can achieve 23 days, compared with PA/PE fi lm, the drip loss of chilled meat that packaged by PE/EVOH/PE and PE/PA/EVOH/PA composite fi lm was lower. PE/EVOH/PE and PE/PA/EVOH/PA composite fi lms can signifi cantly extend the shelf life of chilled meat compared with PA/PE composite fi lm.
