Emulsion activity and emulsion stability index determination
Emulsion activity and emulsion stability index of RBPE were determined by turbidimetric
method of Pearce and Kinsella (1978). Absorbance of emulsion was measured immediately after
emulsion formation at 500 nm and expressed as emulsion activity of protein, and emulsion stability
index was calculated by dividing the absorbance at 500 nm of emulsion at 0 min by the change in
absorbance between 0 and 10 min and multiplied by 10 min.
