Dynamics of changes in the content of betalain pigments in red beet roots during the growing season and storage

Purpose. Betalains, plant pigments of red beet roots, exhibit antioxidant activity and reduce the risks many pathological conditions. However, widespread introduction betalains is hampered by insufficient knowledge their transformations during growing season storage root crops, which was purpose work. Methods. Root crops five varieties table beets were used in studies. The content stability determined spectrophotometric methods according to numerical indices absorption spectra extracts from crops. Results. In roots first 20 days vegetation after germination, betaxanthines higher than that betacyanins, but 40th day, betacyanins exceed over betaxanthin ratio 1.26-2.21. By 70th 90th vegetation, main pool formed, reaches 84.5-198.6 mg / 100 g, betaxanthins resistance are 2.47-9.76 0.82-0.91 respectively. highest excess 8.11 9.65 times obtained Creolka Veselaia Smulyanka varieties. six-month decreases less 1.4 times. Conclusion . It advisable use developed method for determining express analysis Betalains more stable other antioxidants. Beet preferred fortifying diets foods with activity.
