DPPH is an effective method generally used to persuade
antioxidant activity (Scherer and Godoy, 2009). It is based
on hydrogen donation ability and has desirable correlation
with other procedure. Plant extracts that present antioxidant
activity (OAA) values lower than 0.5 can be considered weak
antioxidants. Thus all flours and pasta samples are having
strong antioxidant activity (Table 3). Phenolic compound rich
foods have been shown to possess antioxidant properties. Millets
contain phytochemicals that may provide beneficial health
effects other than basic nutrients. Total phenolic content and
antioxidant activity of flours and pasta samples before and
after cooking are presented in Table 3. The total phenolic content
of millet flours (finger and pearl millet) were significantly
different (p < 0.05) than carrot pomace and durum semolina.
Compared to control pasta (0.22 mg GAE g1
), developed
millet-pomace based pasta showed significantly higher total
phenolic content (0.67 mg GAE g1
). Both cooked pasta samples
are having significantly lower phenolic content than
uncooked pasta (Table 3). This decrease in phenolic content
of cooked pasta samples may be due to leaching of these compounds
into cooking water (Verardo et al., 2011; Hirawan
et al., 2010). However total phenolic content of gruel was
not analyzed in present study. Similarly antioxidant activity
of millet flours is significantly higher (p < 0.05) than durum
semolina and carrot pomace. The reason for the same may
be the higher total phenolic content in millet flours attributing
higher antioxidant activity. Uncooked developed milletpomace
based pasta showed high antioxidant activity
(38.45%) than uncooked control pasta (10.54%). This increase
in antioxidant activity in case of developed millet-pomace
