In this study, rapeseed oil bodies (RPOBs) were used to prepare curcumin emulsions (CEs) in order to investigate their stability and gastrointestinal. The results showed that particle size significantly reduced (p < .05) with increasing RPOBs concentrations from 1.0 to 6.0 wt%. Additionally, CEs showed good stability at pH 2.0-10.0. However, CEs were instable at salt concentration ranging from 100 to 500 mM and at temperatures between 35 and 95 C. CE fat droplet size after 30 min of digestion time exhibited a remarkable increase (p < .05) compared with other times. Upon exposure to simulated intestinal fluid (SIF) conditions, CEs particle sizes gradually decreased with increasing digestion time. Then, 56% curcumin and 40 μmol/ml free fatty acids were produced from CEs after 180 min digestion time under SIF conditions. Practical applications: Our findings indicate that rapeseed oil bodies as a novel carrier can be applied for the delivery-controlled release of lipophilic bioactive compounds from emulsions during gastrointestinal digestion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
