Abstract
Centella asiatica essential oil has various benefits for the health of the body, including having antibacterial and antioxidant properties. Apart from being in the form of gel capsules, essential oils are generally encapsulated in the form of microcapsules. This research examines the yield of Centella asiatica essential oil microcapsules encapsulated by the complex coacervation method, where evaluation is carried out on the effect of the emulsion speed with the coating used and the addition of acetic acid in lowering the product pH. Several analytical parameters used include yield, microcapsule size, chemical compound content, acid number, ester number, and solubility. The ANOVA method was used in the evaluation process using a 2-factorial randomized block design.
