摘　　要：目的:研究丁香精油(Clove Oil,CEO)添加量对CEO/壳聚糖(Chitosan,CS)复合膜性能(光学性能、力学性能等)的影响及不同CEO添加量复合膜对米饭在常温条件下保鲜的作用效果。方法:采用不同质量分数(0%、0.5%、1%、1.5%、2%)的CEO与一定量的CS通过共混的方式制备复合膜,对复合膜的各项理化性能及内部结构进行表征,对米饭进行保鲜处理,测定CEO/CS复合膜保鲜米饭在常温贮藏期间菌落总数及感官评价指标。结果:添加1.5%CEO的CS复合膜综合性能最好,水蒸气透过率为3.80×10^(-3) g/(h·m·kPa),断裂伸长率为40.33%,对米饭的抑菌防腐效果最优,能有效抑制米饭贮藏期间微生物的生长,与CK组和PE组相比可延长米饭货架寿命2 d。结论:添加CEO可以改善CS复合膜的性能,1.5%的添加量可以保持米饭在贮藏期间的营养品质,为CEO在方便米饭保鲜领域的应用提供参考。Objective:To investigate the effect of adding clove oil(CEO)on the properties of CEO/chitosan(CS)composite films,including optical and mechanical properties.Additionally,it explored the effectiveness of these films with varying amounts of CEO in maintaining the freshness of cooked rice under room temperature.Methods:Composite films were developed using a chitosan matrix and blended with varying CEO contents(0%,0.5%,1%,1.5%,2%).Their physicochemical properties and internal structure were characterized.These films were applied to cooked rice,and the total colony count and sensory evaluation indicators were monitored during the rice's storage period.Results:The composite film with a 1.5%addition of CEO exhibited the optimum overall performance,with the water vapor permeability of 3.80×10^(-3) g/(h·m·kPa)and the elongation at break of 40.33%.Additionally,the film efficiently decreased the total colony count of rice during storage.Compared with the control(group CK and PE),the rice treated with the film could effectively extending shelf life by an additional 2 d.Conclusion:Adding CEO was able to enhance the properties of chitosan composite films.The addition content of 1.5%efficiently maintained the quality of cooked rice during storage.This study can provide a reference for the application of CEO in the preservation of ready-to-eat rice.
