Stability of oil-in-water emulsions can be achieved by chemical modified starch, such as octenyl succinic anhydride (OSA) starch, as emulsifier. In order to analyse disperse and rheological characteristics of emulsions containing two kind of emulsifiers, part of the OSA starch can be substituted with adequate concentration of sodium dodecyl sulphate (SDS), which is small surfactant with same charge as OSA starch. Oil contents of examined emulsions were 5, 20 and 50%. Selected OSA starch concentration was 10% and replacements of the part of OSA starch were realized with SDS concentrations of 1, 3 and 5%. Dispersed droplets of emulsions were defined by determination of Sauter mean diameter d32 and particle size distribution. Flow curves were used to describe rheological properties of the emulsions. Also, stability of emulsion samples was observed and expressed by the creaming index. Obtained results indicated decrease in Sauter mean diameter of droplets, standard deviation and apparent viscosity of emulsions while amounts of SDS increase within emulsifiers mixture OSA starch-SDS. The emulsions with OSA starch according to creaming rate were more stable than emulsions stabilized by OSA starch and SDS combination
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.
