yielding a total POP content ranging between 42.9 and
57.4 mg/100 g of PS. No statistically significant differences (p>0.05) in total and individual POP content
according to the source of PS were found. The mean β-sitosterol oxidation percentage was b0.07%, which
reflected a low PS oxidation extent, though manufacture was on a laboratory scale regardless of the PS
source used in enrichment of the functional beverages. These functional drinks therefore can be regarded
as healthy food products and as an adequate PS vehicle as well.
