Thesis Title
Development of microemulsion delivery systems for bioactive compounds

Due to their health-promoting properties, bioactive compounds have attracted considerable interest in several fields. However, bioactive compounds used as functional ingredients in foods are limited due to their poor solubility, chemical instability, and undesirable sensory attributes. This leads to poor oral bioavailability as well as reduced consumer acceptance. Ms Yuan successfully formed microemulsions via an emulsion dilution method and water titration method which act as a delivery system to encapsulate and protect bioactive compounds from degradation. During storage under different environmental conditions, the degradation rate of beta-carotene was much slower when it was incorporated into a microemulsion than when it was mixed with hexane solution. The fabricated microemulsions in this study could possibly be applied to some liquid foods and beverages.
