Concentrated orange oils (5x, 10x, 20x) are ingredients used in different industries as components of flavors and aromas due to their great organoleptic qualities. This research focuses on the search for alternative uses for their application through encapsulation in inclusion complexes with β-cyclodextrin (β-CD). Inclusion complexes of concentrated orange oils (COEO) and β-CD were developed by the co-precipitated method in ratios of 4:96, 12:88, and 16:84 (, COEO β-CD). The best powder recovery was in the ratio 16:84 for the three oils, with values between 82% and 84.8%. The 20x oil in relation 12:88 showed the highest entrapment efficiency (89.5%) with 102.3 mg/g of β-CD. The FT-IR analysis may suggest an interaction between the oil and the β-CD. The best antioxidant activity was observed in the ratio 12:88 for the three oils. The antifungal activity was determined for all the inclusion complexes, and the 10x fraction showed the highest inhibition at a concentration of 10 mg/mL in ratios 12:88 and 16:84. Antibacterial activity was determined by the minimum inhibitory concentration (MIC) and was found at a concentration of 1.25 mg/mL in ratios 12:88 and 16:84 for 5x and 20x oils.
浓缩橙油（5x、10x、20x）因其良好的感官品质，被用作不同行业的香精和香料成分。本研究专注于寻找其应用的替代用途，通过与β-环糊精（β-CD）包合形成包含物复合物来实现。采用共沉淀法制备了浓缩橙油（COEO）与β-CD 的包含物复合物，其摩尔比分别为 4:96、12:88 和 16:84（COEO-β-CD）。三种油中，16:84 比例下粉末回收率最好，为 82%至 84.8%。在 12:88 比例下，20x 油的包封效率最高（89.5%），β-CD 为 102.3mg/g。FT-IR 分析可能表明油与 β-CD 之间存在相互作用。三种油中，在 12:88 比例下观察到最佳的抗氧化活性。对所有包含物复合物进行了抗真菌活性测定，在 10mg/mL 浓度下，10x 部分在 12:88 和 16:84 比例下表现出最高的抑制作用。通过最小抑菌浓度（MIC）测定了抑菌活性，在 12:88 和 16:84 比例下，5x 和 20x 油的浓度分别为 1.25mg/mL。
