Equivalent amount of emulsified phytosterols were added into the milk,fruit juice and
juice-milk beverage.All the beverages were stored at 4,20,35 ℃ for three months and the
content of phytosterol oxidation products(POPs)and phytosterol were determined at regular
time every other month.The results showed that the contents of POPs in milk were the highest,
followed by fruit juice and juice-milk beverage.The highest contents of POPs in the milk stored
at 35℃ were(357.09±26.48)μg/g,the losses of total phytosterol were(25.50±1.03)%after
three months,and the lowest contents of POPs in the juice-milk beverage stored at 35℃ were
(237.65±16.48)μg/g and the losses of total phytosterol were(2.95±0.37)%.The three
beverages of different matrix containing phytosterols were stored at room temperature under light
and dark conditions,respectively and the contents of POPs in the light group were significantly
higher than that in the dark group.
