Abstract

In this study, our previously prepared chitosan/pullulan film (CS/PU) and chitosan/pullulan/carvacrol film (CS/PU/CAR) were applied to goat meat preservation, the dynamic changes in quality and microbial communities of goat meat during chilled storage (4 °C) were investigated, and the fresh-keeping effects of the two biodegradable antibacterial films on goat meat were comprehensively evaluated. The results showed that when the goat meat was wrapped with CS/PU or CS/PU/CAR films during chilled storage, the total plate count and total volatile basic nitrogen (TVB-N) could be inhibited significantly, but the CS/PU/CAR film has a better fresh-keeping effect. Furthermore, during the chilled storage of goat meat, CS/PU/CAR film also could inhibit the production of alcohol compounds and the growth of Pseudomonas spp., thereby slowing down the meat's deterioration and extending the goat meat's shelf life to about 13 days. This study can provide a reference for the application of active packaging film of fresh goat meat.

壳聚糖/普鲁兰/香芹酚薄膜对冷藏山羊肉质量和微生物多样性的影响

本研究将之前制备的壳聚糖/普鲁兰薄膜（CS/PU）和壳聚糖/普鲁兰/香芹酚薄膜（CS/PU/CAR）应用于山羊肉保鲜，研究了冷藏（4 ℃）过程中山羊肉品质和微生物群落的动态变化，并综合评价了两种可降解抗菌薄膜对山羊肉的保鲜效果。结果表明，在冷藏期间用 CS/PU 或 CS/PU/CAR 薄膜包裹山羊肉，可显著抑制总板计数和总挥发性碱基氮（TVB-N），但 CS/PU/CAR 薄膜的保鲜效果更好。此外，在冷藏山羊肉的过程中，CS/PU/CAR 薄膜还能抑制醇类化合物的产生和假单胞菌的生长，从而延缓肉的变质，将山羊肉的货架期延长至 13 天左右。这项研究可为新鲜山羊肉活性包装膜的应用提供参考。

期刊介绍： The aim of Meat Science is to serve as a suitable platform for the dissemination of interdisciplinary and international knowledge on all factors influencing the properties of meat. While the journal primarily focuses on the flesh of mammals, contributions related to poultry will be considered if they enhance the overall understanding of the relationship between muscle nature and meat quality post mortem. Additionally, papers on large birds (e.g., emus, ostriches) as well as wild-captured mammals and crocodiles will be welcomed.
