The goal of this research is to test the influence of biopolymer emulsifiers; Whey protein concentrate (WPC), Modified starch (MS) and Pea protein/ Maltodextrin mixture on the physical and oxidative stability of rice bran oil-in-water emulsions. All three different types of emulsions were formed at 4.5% by weight emulsifier and 5% by weight oil concentrations. The physical stability of the emulsions was observed by measuring creaming index of each emulsions over time with or without the presence of Fe-EDTA (ethylenediaminetetraacetic acid), a pro-oxidant. The oxidative stability of the emulsions was measured through amount of peroxide over time. After 38 days, rice bran oil in water emulsions that have WPC and MS have stable creaming index numbers and low peroxide presence: 8% without Fe-EDTA and 10% with Fe-EDTA for WPC, 15% without Fe-EDTA for MS. However, the creaming index of MS with Fe-EDTA showed 100% creaming index and 60 mg of peroxide at 38 days. Pea Protein/Maltodextrin mixture was not stable enough to keep the emulsion over time, 100% creaming index, and had the high amount of peroxide, 160 mg. Our result would contribute to the viability of using WPC, MS and Pea protein as emulsifiers in rice bran oil emulsions.
