Abstract
Sweet orange (Citrus sinensis L.) is the most widely consumed citrus fruit in Côte d'Ivoire. They are rich in bioactive compound. Also, their peels or flavedo rejected during consumption have a high content of polyphenols, flavonoids, and essential oils. However, in Côte D'Ivoire, studies are limited to the characterization of orange peel (Citrus sinensis). Our study therefore aims to determine the phytochemical composition of herbal teas obtained from the orange peel (Citrus sinensis) in order to contribute to their valorisation as herbal teas. The Citrus sinensis zests were collected in Abidjan (Côte d'Ivoire) in Adjamé community. An herbal tea was produced and subjected to phytochemical and physicochemical tests. The results showed that the moisture content of the different batches varies from 14.13±0.41 to 7.2%±0.2; the oven-dried batches showed the lowest value. In addition, the ash content remains statistically different between batches. The herbal teas studied had an average ash content of 6.53%. The pH values negatively correlated to acidity range from 3.92±0.2 to 3.21±0.15. Also, these herbal teas contain several secondary metabolites such as polyphenols, flavonoids, alkaloids, tannins and saponins. This study shows that herbal teas made from orange peel contain several phytochemicals including antioxidants. In addition, their high ash content suggests a high mineral content. Therefore, orange peels can be used in the form of herbal teas as a dietary supplement.
