Abstract
Abstract: In the present work, olive oil stability in Pickering emulsion from eucalyptus pulp was determined. The effect of oil concentrations, modified ammonium persulphate cellulose nanocrystals (APS-CNC) concentrations and pH on the drop sizes and distribution of Pickering emulsion were established. The emulsion stability was investigated in terms of zeta potential, %emulsion physical stability (ES) and %remains antioxidant activity. The smallest drop size of 8.00 ± 3.94 µm was obtained at 0.1 wt% of APS-CNC concentration, 10 wt% of oil concentration and pH 7. Also, the maximum %remain antioxidant activity of 44.94 ± 3.66% was acquired at 0.1 wt% APS-CNC concentration at pH 7 after 30 storage days. The rheology behaviour of these Pickering emulsions caused by shear-thinning fluid. This fluid behaviour can be applied to liquid food, cream and oral drug delivery with a nanocarrier.
