Emulsion-based delivery systems for curcumin: Encapsulation and interaction mechanism between debranched starch and curcumin

Curcumin has been widely recognized as health-promoting compound. However, the intrinsic hydrophobicity, chemical instability and photodegradation limits its applications in foods. In this study, a novel emulsion was developed to encapsulate curcumin using debranched starch (DBS). The encapsulation efficiency of curcumin was 71.11% with a loading rate of 12.07%. The prepared emulsions showed better stability and solubility of curcumin than those stabilized only with Tween80 and lectin. The DBS incorporated emulsion had a uniform droplet size distribution with an average value of
