摘要:

为了验证尼龙-聚乙烯(polyamide/polyethylene,PA/PE)复合膜对鲜切莴笋的保鲜效果,将新鲜莴笋切片真空包装后在4 ℃条件下冷藏,不加任何包装的鲜切莴笋同样条件下作空白对照。贮藏期间评价菌落总数、色差、pH值、汁液流失率、VC含量、感官等指标。结果PA/PE组贮藏期达24 d,而不加包装的对照组只有4 d。可见对于鲜切莴笋的贮藏,PA/PE复合膜结合真空包装可明显延长其贮藏期。

Abstract:

In order to explore the effect of polyamide/polyethylene (PA/PE) composite membrane on the quality maintenance
of fresh-cut stem lettuce, fresh-cut slices of asparagus lettuce were vacuum packaged with PA/PE composite membrane and
refrigerated at 4 ℃ and those not packaged with the composite membrane under the same storage condition were used as
blank control. The total bacterial count, color, pH, drip loss, vitamin C, and sensory quality of fresh-cut asparagus lettuce
were evaluated during storage. The results showed that the shelf life of fresh-cut asparagus lettuce packaged with PA/PE membrane
was 24 days, while that of the blank control was only 4 days. Thus, PA/PE composite membrane combining with vacuum
packaging technology could extend the shelf life of fresh-cut asparagus lettuce obviously during refrigerated storage.

Key words: packaging, PA/PE, fresh-cut, asparagus lettuce
