Mineral Elements Composition in two varieties of Tomatoes consumed in Kinshasa (Solanum lypersicum var cesariforme et Solanum lypersicum mill)

Two varieties of Solanum Lypersicum (var cesariforme and mill) consumed in Kinshasa in the Democratic Republic of the Congo were analyzed for the determination of mineral composition and the identification of antioxidants. Mineral element analyzes were conducted by the ICP-AES (Atomic Inductive-coupling Plasma Spectrophotometry). Antioxidants have been identified by solution reactions.

By applying the statistical t test of Student (=0.05), the composition of mineral elements differed significantly between the two varieties studied. Mineral elements such as calcium, sodium, magnesium, potassium, zinc, iron, and manganese, copper are more abundant in the variety Solanum lypersicum var cesariform. Polyphenols, flavonoids, and carotenoids are organic antioxidants identified in these samples.

The two varieties of tomatoes analyzed are a significant source of mineral and antioxidants elements. Téléchargé l'article
