Abstract |
Effect of mango kernel fat (MKF) on antioxidant characteristics and lipolysis of Gouda cheese was investigated. Milk fat (3.5%) was partially replaced with MKF i.e. 5, 10, 15 and 20% concentrations (T1, T2, T3and T4). Cheese prepared from 100% milk fat served as control. Cheese samples were ripened for 90 days at 6 ± 1 °C and analysed at 0, 45 and 90 days of ripening. Total phenolic contents of control, T1, T2, T3and T4were 14 ± 0.35, 129 ± 0.75, 188 ± 2.52, 267 ± 10.61 and 391 ± 8.46 mg GAE/g. Total flavonoid content of control, T1, T2, T3and T4were 0.22 ± 0.03, 1.47 ± 0.09, 3.62 ± 0.15, 5.88 ± 0.35, 8.29 ± 0.63 mg quercetin equivalent/ml. DPPH free radical scavenging activity of control and experimental samples increased throughout the ripening period. DPPH free radicals scavenging activity of 90 days old control, T1, T2, T3and T4were 16.38 ± 0.0.26e, 30.47 ± 0.64d, 68.62 ± 0.91c, 73.29 ± 0.85b, 92.61 ± 1.44a %. HPLC characterization revealed the existence of mangiferin, caffeic acid, catechin, quercetin and chlorogenic acid in MKF fortified Gouda cheese. Fortification of MKF increased the concentration of C18:1, C18:2 and C18:3 in cheese. The concentration of C18:1, C18:2 and C18:3 in control were 24.55 ± 0.95, 1.76 ± 0.09 and 0.31 ± 0.02%. While, the concentration of C18:1, C18:2 and C18:3 in T4were 30.11 ± 1.34, 2.79 ± 2.79 and 0.92 ± 0.11%. MKF fortified Gouda cheese had better oxidative stability and sensory characteristics. These results evidenced that antioxidant capacity, unsaturated fatty acids and oxidative stability of Gouda cheese can be improved with MKF. |
