3.1. Red Beetroot Juice Composition
6174 ±
The chemical composition of the commercial RBJ was assessed by NMR spectroscopy in order to identify the metabolites which could act as substrates or could be absorbed in the intestinal mucosa in relation to the intake. For this purpose, five replicates of hydroalcoholic extracts of RBJ were analyzed, and a representative spectrum of red beetroot hydroalcoholic extract is reported in The analysis of the hydroalcoholic extracts of beetroot juice showed a considerable amount of carbohydrates (total amount: 6174 ± 454 mg/100 mL), amino acids (total amount: 427 ± 7 mg/100 mL), and some bioactive molecules, including betaine, betanin, dopamine, and other antioxidant molecules.
