Effect of flesh colour on the content of major antioxidants in potato tubers from organic cultivation

Original language description

In 2010 a field trial at the Experimental station of the Czech University of Life Sciences in Prague Uhříněves in terms of organic conditions with 6 blue- or red-fleshed potato varieties and with the yellow-fleshed control Agria variety was performed. After harvest, tubers were analyzed for the content of chlorogenic acid (ChA), ascorbic acid (AA) and total anthocyanins (TA). Flesh colour significantly influenced the ChA content, which was in the varieties with coloured flesh from 1.29 to 1.88 times higher in comparison with the yellow-fleshed Agria variety. Significant differences in the content of ChA were found among the different varieties with coloured flesh, a decrease of the variety with the lowest content to the highest content was 31.6 %. In contrary, AA content did not depend on the colour of the flesh, but the genotype of each variety, as the difference of AA contents between the Blaue Elise (176.7 mg/kg FM ? blue-fleshed), Agria (170.6 mg/kg FM - yellow-fleshed) and Highlan
