Radical scavengers may directly react and
quench with peroxide radicals to terminate the
peroxidation chain reaction and improve the quality and
stability of food product. The stable DPPH radical has
been used to evaluate antioxidants for their radical
quenching capacity [31,32] and to better understand
their antioxidant mechanism(s) each fenugreek extract
was evaluated for radical scavenging activity against
DPPHo. The decrease in absorbance of DPPH radical is
caused by antioxidant through the reaction between
antioxidant molecule and radical results in the
scavenging of the radical by hydrogen donation. As
