摘　　要：为开发一种兼具肉类新鲜度智能指示和保鲜作用的复合膜,以壳聚糖为成膜基材,甘油为增塑剂,多甲氧基黄酮为抑菌剂,花青素为显色剂,研究花青素和多甲氧基黄酮对复合膜的机械性能、阻隔性能、透过性能、指示性能、保鲜性能的影响。结果表明,在4℃条件下,该复合膜可将猪肉的货架期延长至7 d,优于未覆膜空白组、聚乙烯保鲜膜和壳聚糖膜对照组。当复合膜呈现蓝灰色、浅棕红色和深棕红色时分别对应新鲜肉、次鲜肉和变质肉,可以实现实时、无损地指示猪肉的新鲜度。This study was carried out in order to develop a composite film that serves the dual function of acting as an intelligent indicator for meat freshness and preserving meat using chitosan(CS)as the film-forming substrate,glycerin as the plasticizer,polymethoxy flavones(PMFs)as the bacteriostatic agent and anthocyanin(AC)as the color developing agent.The effects of AC and PMFs on the mechanical,barrier,permeability,indicator and preservative properties of the composite film were investigated.The results showed that the composite film extended the shelf life of pork to 7 d at 4℃,this effect being more pronounced than that of blank group without film coating,control groups coated with polyethylene film and CS film.The composite film exhibited blue gray,light brown red and dark brown red colors for fresh,second fresh and spoiled meat respectively,and can enable real-time and non-destructive indication of pork freshness.
