The antioxidant activity of the studied raw material and the
flour manufactured as a supplement of trade grits in snack pellet’s
in the conditions related to proceeded in potato industry, was
expressed as ABTS and DPPH and by a method utilising the reduction
properties of ferric ions (FRAP). As shown in Table 1, the antioxidant
and antiradical activity of the potatoes depended on the
variety. The highest activity was observed in tubers of the Blue
Congo potato variety and significantly lower activity, expressed
as FRAP and DPPH, in the red-fleshed potatoes of Herbie 26. Similarly,
other authors (Lachman et al., 2008; Lachman et al., 2009)
proved that the antioxidant activity of coloured-flesh potatoes
depends on the variety and on the place of their cultivation and
weather conditions during the growing of the potato plant.
