Abstract
The chemical composition and sensory evaluation of yoghurt supplemented with green tea (GTE) or green coffee (GCE) extracts and its effect on reducing obesity complications in rats were investigated. Ethanol extracts were prepared from green tea and green coffee and their total phenolic compounds and identified phenolic compounds were evaluated. Results showed that the GTE and GCE have containing highly antioxidant activities. Yoghurt was prepared from low fat buffalo's milk (1.5% fat) blended with 1 % of GTE or GCE. Addition of GTE or GCE had significant effects on the chemical composition and sensory evaluation. Higher sensory scores were reported flavor for GTE and GCE yoghurt than control. It was also noticed that addition of GTE or GCE to yoghurt increased viscosity a key defensive effect on the gel-factors. Feeding of obese rats on yoghurt adding to GTE or GCE showed that significant differences reduced of weight compared to positive group. There are not found significant differences of heart weights tissue while, kidney and liver weights tissues were significant differences. Also, fed obese rats on yoghurt supplemented with GTE or GCE decreased the lipids profile comparative with positive control group and improvement of liver and kidney functions. The best treatment was observed in yoghurt adding to green coffee beans extract which had reduced value of liver and kidney function parameters followed by yoghurt adding to green tea extract. The histopathological examination observed normalized in the groups fed yoghurt supplemented green tea and coffee beans extracts. Supplemented yoghurt with green tea and coffee extracts could be increased the useful health effects of yogurt by intensifying antioxidant activity which had therapeutic effects on obese rats.
