Groundnut seeds (Arachis hypogaea) contain higher concentrations of unsaturated lipids which are prone to oxidation in formulated foods. This study determined the antioxidant activities of water extract powders from two spices (Syzigium aromaticum and Allium sativum) and their ability to preserve the quality of lipids in groundnuts pudding during steam cooking with 0, 0.5, 1, 2 and 4% of spice extract powders. Total phenolic (TPC) and flavonoid (FC) contents of extracts from S. aromaticum were 140.23 mg GAE/100g extract and FC of 110.34 mg CAE/g extract compared to values of Allium sativum extracts (54.28 mg GAE/100g extract and 34.80 mg CAE/g extract). The showed DPPH free radical scavenging activities of the extract from S. aromaticum depending on the concentration ranged from 82.15% to 97.66% and this was higher than the activities of A. sativum but comparable to the values of buthylhydroxytoluene used as control. The chemical analysis of oil extracted revealed that the addition of the spice extract powders limited the appearance of oxidation products characterized by a reduction of up to 9-fold of peroxide value, 5-fold for anisidine and 2-fold for thiobarbituric acid reactive species. In many cases, the addition of S. aromaticum spice extract powder to the pudding better prevented lipid oxidation likely because of its superior ability to scavenge peroxyl radicals (ROO., HO., DPPH.). In a nutshell, the addition S. aromaticum and A. sativum spice extract powders on grilled groundnuts paste for groundnuts pudding preparation in household can help preserve its lipid quality. |
