| dc.description.abstract | Indonesia is the largest palm oil producer in the world. One of the palm oil derivative products is palm oil emulsion as its β-carotene solubility in water is low and easily degraded through processing. The use of nanotechnology in the manufacture of palm oil nano emulsion can improve its solubility in water, its bioavailibility in the digestive tract, and emulsion stability. This study observed the effect of emulsifier Tween 20 and Tween 80 as much as 10% and 30% (w/w) oil base and chitosan 0%, 0.5%, and 1% (w/v) emulsion base to the particle size and stability. The use of Tween 80 provided better particle size and stability of β-carotene than the use of Tween 20. The use of an emulsifier at a concentration of 30% showed a smaller particle size compared with the use of a concentration of 10%. The use of chitosan to 1% can increase the size of the particles and prevent oiling off, but can accelerate the aggregation of the emulsion, compared to 0.5% chitosan use. The selected formula is the use of 30% Tween 80 and 0.5% chitosan. | en |
