Abstract:
In this study, producing flavored functional yogurt enriched with flavonoid and oil extracted from orange peel was investigated and some sensory and physicochemical properties of yogurt produced were evaluated during 15-day storage time. This study was carried out in 2 steps: the first; flavonoid and oil were extracted from orange peel, and then, flavored functional yogurt samples enriched with different percentages of flavonoid (7, 8 and 9%) and oil (0, 0.5, 1 and 1.5%) extracted from orange peel were produced. The results showed that an increase in the concentration of orange peel oil induced a decrease in acidity and synersis; and an increase in pH, fat and dry matter of yogurt samples. By increasing flavonoids content, the A parameter increased too. The yogurt sample with 8% flavonoids and 0.5 g oil/100 g yogurt received the most sensory scores.
