Abstract

The starch nanocrystals (SNC) used in this study were made of sago starch and prepared by using sulfuric acid hydrolysis of sago starch. The aim of this study is to look at the potential of SNC as and emulsifier. Previously, the SNC underwent analytical analysis in order to understand and evaluate the isolated SNC. The ability of SNC as emulsifier was further investigated in this study. Emulsions with low, medium and high oil content has been prepared in function of different wt% of SNC. The emulsion stability against coalescence for two weeks has also been studied. Results showed that the emulsions prepared are steadily stable after one weeks of storage without any separation and changes. From the observation, there are two major factor contributed to the formation of emulsion and its stability, the SNC concentration and oil content. Relatively, higher percentage of SNC resulting a higher emulsion index, whereas no emulsion was formed if oil content exceeding 50% of the systems. The most suitable formulation to prepare Pickering Emulsion is the oil content around 45% and SNC concentration around 2-4%.
