Abstract

This study examined the impact of emulsifier type on the physicochemical characteristics and antifungal capacity of oregano oil-in-water emulsions: Tween 80, hydroxylated soy lecithin, and gum arabic. GC/MS analysis showed that the major components of the essential oils were thymol (31.7%), -cymene (18.7%), and carvacrol (14.6%). The oil-in-water emulsions were made using ultrasonic technology in which thymol and carvacrol quantities were 12.26-13.67 g/L and 5.6-6.2 g/L, respectively. The droplet size of the emulsions followed the next descendent order: gum arabic > lecithin > T80. The zeta potential of the emulsions favored the stability against coalescence. Finally, the antifungal activity of the emulsions was evaluated, in which, 30 µL/mL of gum arabic or hydroxylated soy lecithin emulsions inhibited the growth of . The result suggests that Mexican oregano essential oil emulsions can be used as an antifungal against of

摘要

本研究考察了乳化剂类型对牛至水包油乳液(吐温80、羟基化大豆卵磷脂和阿拉伯胶)理化特性及抗真菌能力的影响。气相色谱/质谱分析表明,精油的主要成分是百里香酚(31.7%)、对异丙基甲苯(18.7%)和香芹酚(14.6%)。采用超声技术制备水包油乳液,其中百里香酚和香芹酚的含量分别为12.26 - 13.67克/升和5.6 - 6.2克/升。乳液的液滴尺寸遵循以下降序排列:阿拉伯胶>卵磷脂>吐温80。乳液的ζ电位有利于防止聚结。最后,评估了乳液的抗真菌活性,其中,30微升/毫升的阿拉伯胶或羟基化大豆卵磷脂乳液抑制了……的生长。结果表明,墨西哥牛至精油乳液可作为……的抗真菌剂。
