ajst-26896	Zhang, Wenxuan	Study on the Molecular Mechanism of the Effect of Surfactants on the Fragrance Retention of Spices	2024	3	.pdf	application/pdf	2331	100	38	Adding SDS into vanilla essential oil according to a predetermined concentration gradient, and ensuring full and uniform mixing, so as to prepare vanilla essential oil samples with different SDS concentrations; The fragrance retention performance of the samples in the control group and each experimental group was regularly detected and recorded by the olfactory evaluation method [5]; Finally, the data of fragrance retention performance of vanilla essential oil under different SDS concentrations were compared and analyzed to clarify the specific influence law of SDS concentration on its fragrance retention performance. In the control group, in the absence of SDS, the fragrance retention effect of vanilla essential oil gradually decreased with time, showing its natural volatilization characteristics; However, at the concentration of 0.1 mM SDS, although the fragrance retention ability was only slightly improved, it has been shown that low concentration SDS is helpful to enhance the dispersion of vanilla essential oil molecules, thus promoting fragrance retention; When the concentration of SDS is increased to 0.5 mM to 1 mM, the effect of prolonging the fragrance retention time of vanilla essential oil is significantly enhanced, because there is a good balance between SDS and vanilla essential oil molecules, and the formed micelle can not only protect the vanilla essential oil molecules from rapid volatilization, but also ensure their moderate emission to achieve a more lasting fragrance retention effect; However, at the high concentration of 5 mM, although SDS can still play a certain synergistic role, the excessive micelle formation leads to the excessive encapsulation of vanilla essential oil molecules, which hinders its normal volatilization, making the fragrance retention performance slightly lower than the previous two concentration ranges.	cache/ajst-26896.pdf	txt/ajst-26896.txt
