More than 200 researches were searched from 2008 to 2021 related to the Carrot pomace. The results of comparing the antioxidant activity of two Algerian orange carrot varieties showed that the Touchon variety was richer in phenolics, flavonoids, and carotenoids and presents higher antioxidant activity in comparison with the Super-muscade variety.
