摘　　要：该文旨在制备一种新型壳聚糖-连翘精油复合可食膜,以壳聚糖(chitosan,CS)为成膜材料,以不同添加量的连翘精油制备复合可食膜,测定膜的厚度、机械性能、水蒸气透过系数、水溶性、不透明度、吸湿性等指标,并研究其对草莓保鲜的作用。结果表明,添加0.1 mL连翘精油的壳聚糖复合膜综合性能较优,不同添加量的连翘精油-壳聚糖复合可食膜对草莓的保鲜效果表现不一,连翘精油添加量较少的壳聚糖-连翘精油复合可食膜能够降低草莓的腐烂率、失重率,延缓有机酸、VC和可溶性固形物含量的降低,保持较佳的感官品质。该新型复合膜力学性能好、安全有效、对水果的保鲜效果佳,作为新型复合可食保鲜膜,具有广阔前景。This article aims to prepare a novel chitosan(CS)-Forsythia suspensa essential oil(FSEO)composite edible film.To be specific,different amounts of FSEO were respectively mixed with CS to prepare composite edible films.The thickness,mechanical properties,water vapor permeability,water solubility,opacity,moisture absorption and other indicators of the films were measured and the preservation of strawberry was studied.The results showed that the comprehensive properties of the composite film with 0.1 mL FSEO were excellent.The preservation of strawberry by the films prepared with different amount of FSEO varied and the film made with small amount of FSEO could reduce the rotten rate,weight loss rate,slow down the decrease in organic acid,VC,and soluble solid content,and maintain the sensory quality of the fruit.The composite film has desirable mechanical properties and fresh-keeping effect on fruits,which is safe and can be further promoted.
