Nutritional values, antioxidant properties and cytotoxicity of Dioscorea dumetorum chips for valorization in animal and human food in Benin. The aim of this work was to assess the nutritional value and antioxidant properties of D. dumetorum for better use in human and animal nutrition. The fresh tubers were cut into pieces, cooked in water for 30, 60 and 90 minutes, then sun dried to obtain CD30, CD60 and CD90 chips respectively. Chemical and phytochemical assays were carried out on different types of chips. The total ash content varied from 3.36 to 3.55 %. The crude proteins content varied from 7.86 to 9.8 %, while the crude cellulose content varied from 0.69 to 1.71 %. A total of 10 classes of secondary metabolites are present in the chips. The contents of total polyphenols, flavonoids and tannins are higher in the CD30 chips. The rate of free radical inhibition ranged from 51.97 to 54.08 %. The 50 % inhibitory concentration value varied from 2.62 to 12.10 µg / mL in the chips. D. dumetorum is a food resource that antioxidant capacity could help prevent damage caused by oxidative stress and therefore improve productivity in animals.
