We investigated the effect of oil droplet sire on the oxidation rate of DHA
monodispersed emulsion with xanthan. Xanthan-free emulsions creamed rapidl
y but no creaming was observed in the emulsions containing xanthan over 8 w
eeks. While the peroxide value (POV) of the xanthan-free emulsion reached 1
0meq/kg at 20 days, that of both emulsion systems containing xanthan change
d little during the first 20 days. The POV for the emulsion with small drop
let was higher than that for the emulsion with large droplet.
