Ovarian fluid is a mass-production nutritionally valuable byproduct of aquaculture of sturgeons. Total antioxidant activity of freeze-dried pasteurized and non-pasteurized ovarian fluid of Siberian sturgeon (Acipenser baerii) was determined to estimate its potential acceptability as an anti-inflammatory and anti-age agent in nutraceuticals. Total antioxidant activity was determined using the certified coulometric measurement method. The value of total antioxidant activity was about 18.6 ± 1.1% of that of a well-known source of antioxidants – tomato fruits, if calculated by dry weight. There was no statistically significant difference between the values of activity for pasteurized and non-pasteurized ovarian fluid, so it is reasonable to pasteurize the fluid for its preservation.
Key words: ovarian fluid / sturgeon / antioxidant activity / nutraceuticals
