Chemical reagents such as: 1,1-diph

Chemical reagents such as: 1,1-diphenyl-2-picrylhydrazyl
(DPPH) were purchased from Fluka (Switzerland) while Folin
Ciocalteu’s (FC) phenol reagent was from Sigma-Aldrich
(St. Louis, MO, USA). Hydrogenated fat in the form of margarine, citric acid (2-hydroxypropane- 1, 2, 3-tricarboxylic acid),
