Thymol oil-in-water nanoemulsions as a potential natural alternative for synthetic antioxidant agents were developed. The nanoemulsions were formulated using Quillaja Saponin bio-surfactant and green solvents including high oleic sunflower oil (HOSO), tricaprylin (TC), and cinnamaldehyde (CA). The 4% thymol nanoemulsions containing TC and HOSO remained stable during long-term storage (at least 30 d). The antioxidant activity (AA) of free thymol and thymol nanoemulsions was compared with butylated hydroxytoluene (BHT) and ascorbic acid. The results obtained from DPPH, FRAP, and CUPRAC antioxidant assays showed a substantial improvement (p < 0.05) of the AA of free thymol through emulsification. The outcomes from the AA of the nanoemulsions in raw chicken breast meat measured by the TBARS assay revealed a significant improvement (p < 0.05) of the AA when thymol was encapsulated. These nanoemulsions may be applicable in the food industry as well as in cosmetic and health care products.
研究开发了水包油型百里香精油纳米乳，作为合成抗氧化剂的潜在天然替代品。该纳米乳采用 Quillaja Saponin 生物表面活性剂和绿色溶剂（包括高油酸葵花籽油（HOSO）、三辛酸甘油酯（TC）和肉桂醛（CA））配制而成。含有 TC 和 HOSO 的 4%百里香纳米乳在长期储存（至少 30 天）过程中保持稳定。游离百里香和百里香纳米乳的抗氧化活性（AA）与丁基羟基甲苯（BHT）和抗坏血酸进行了比较。DPPH、FRAP 和 CUPRAC 抗氧化测定结果表明，乳化可显著提高游离百里香的 AA（p<0.05）。TBARS 测定法测定生鸡胸肉中纳米乳 AA 的结果表明，包封百里香可显著提高 AA（p<0.05）。这些纳米乳可适用于食品工业以及化妆品和保健品。
