摘　　要：以壳聚糖为壁材,甜橙油为芯材,三聚磷酸钠(TPP)为交联剂,采用复凝聚法制备甜橙油纳米微胶囊,通过单因素试验和正交试验对其工艺条件进行优化,并分析甜橙油纳米微胶囊的粒径大小及分布、表面结构、物理稳定性、热稳定性、包埋情况等。结果表明:复凝聚法制备甜橙油纳米微胶囊的最佳工艺条件为壳聚糖质量浓度1.8 mg/mL,吐温20质量浓度1.2 mg/mL,甜橙油质量浓度3.6 mg/mL;在该条件下制备的甜橙油纳米微胶囊乳化液的平均粒径为500 nm左右,呈正态分布,物理稳定性良好;甜橙油纳米微胶囊具有较好的热稳定性;红外光谱显示甜橙油被成功包埋于壳聚糖中。Using chitosan as the wall material,sweet orange oil as the core material,and sodium tripolyphosphate(TPP)as the cross-linking agent,the sweet orange oil nanocapsules were prepared by the complex aggregation method.Through single factor test and orthogonal test,the process conditions were optimized,and the evaluation of particle size and distribution,surface structure,physical stability,thermal stability and embedding situation of sweet orange oil nanocapsules were analyzed.The results showed that the optimal process conditions for preparing sweet orange oil nanocapsules by complex aggregation method were chitosan mass concentration 1.8 mg/mL,tween 20 mass concentration 1.2 mg/mL,and sweet orange oil mass concentration 3.6 mg/mL;The average particle size of the sweet orange oil nano-microcapsule emulsion prepared under the optimal conditions was about 500 nm,showing a normal distribution,and the emulsion had good physical stability.The orange oil nano microcapsule had good thermal stability.Infrared spectroscopy showed that orange oil was successfully embedded in chitosan.
