Jasmine Essential Oil‐Mediated Off‐Flavour Masking of Camellia Oil and Preparation and Performance Study of <scp>ROS</scp> ‐Responsive Microcapsules

ABSTRACT Camellia oil contains a variety of bioactive substances and plays an important role in protecting and repairing the skin barrier. However, its volatile components have an unpleasant smell, which has a significant impact on consumer preferences. To enhance the application of camellia oil in the cosmetics field, this study selected 15 key characteristic aroma components of camellia oil and investigated the influence of jasmine essential oil on these key aroma components. Subsequently, the composition oil was encapsulated using β‐cyclodextrin grafted with 4‐(hydroxymethyl)phenylboronic acid pinacol ester. Studies have shown that jasmine essential oil has a masking effect on 11 out of the 15 key aroma components of camellia oil, and an additive effect on 4 of them. The microcapsules prepared with the modified β‐cyclodextrin were in block form, and the release rate reached 58% within 72 h under ROS conditions, while that of the unmodified one was only 22%. This study significantly improved the sensory and storage properties of camellia oil, greatly enhancing its application value in the skincare products field. Moreover, the prepared microcapsules also demonstrate potential application value in fields such as drug delivery and biomedicine.
