在这项研究中，由1%（w/v）海藻酸盐（Alg）和依兰精油（YYEO，0.1%，0.3%和0.5%）组成的可食用膜首次制备和表征。藻酸盐悬浮液粘度从255.8 Cp显著增加到290.5 Cp，相应的膜厚度从0.029 mm显著增加到0.043 mm。水分含量（MC%）也从30.22%显著降低至23.93%。扫描电子显微镜和原子力显微镜分析表明，增加Alg/YYEO膜的粗糙度。通过傅里叶变换红外光谱和共聚焦激光扫描显微镜证实了海藻酸盐膜中YYEO的存在。添加YYEO对总色差（ΔE）无显著影响。拉伸强度降低，断裂伸长率（EAB%）显著（p< 0.05）增加83.11%。Alg/0.3%YYEO薄膜的透湿性较其它薄膜有明显改善。Alg/0.5%YYEO涂膜具有较强的抗氧化清除能力（27.94%），不透明度为3.60 A/mm，Alg/0.3%YYEO和0.5%YYEO涂膜液对番茄灰霉病菌的抑菌效果均有显著提高。因此，海藻酸盐薄膜纳入YYEO是可行的材料，可食用的薄膜和涂层在新鲜农产品包装。
In this study, edible films composed of 1% (w/v) alginate (Alg) and ylang‐ylang essential oil (YYEO, 0.1%, 0.3%, and 0.5%) were fabricated and characterized for the first time. The alginate suspension viscosity increased significantly from 255.8 to 290.5 Cp, with a corresponding significant film thickness increase from 0.029 to 0.043 mm. There was also a significant decrease in moisture content (MC%) from 30.22 to 23.93%. Scanning electron microscopy and atomic force microscopy analyses showed an increased Alg/YYEO film roughness. The presence of YYEO in the alginate film was confirmed by Fourier transform infrared spectroscopy and confocal laser scanning microscopy. YYEO addition induced no significant change in total color difference (ΔE). There was a decrease in tensile strength and a significant (p< 0.05) increased elongation at break (EAB%) by 83.11%. The Alg/0.3% YYEO film demonstrated improved water vapor permeability compared with the other films. The Alg/0.5% YYEO film had strong antioxidant scavenging properties (27.94%), and an opacity of 3.60 A/mm. Both the Alg/0.3% YYEO and 0.5% YYEO coating solutions greatly improved antifungal properties againstBotrytis cinerea. Therefore, alginate films incorporating YYEO are viable materials for edible films and coatings in fresh produce packaging.
