Contribution of melanoidins from heat-processed foods to the phenolic compound intake and antioxidant capacity of the Brazilian diet.

ABSTRACT: In the present study we aimed at studying, determined and estimated the daily intake the contents of melanoidins and of their phenolic-bound compounds, and the antioxidant capacity of thermally processed foods regularly consumed in the Brazilian diet. Among twenty-three heat-processed Brazilian food samples, melanoidins contents ranged from 1.6 (dulce de leche) to 21.4 g/100 g (soluble coffee). Considering melanosaccharides, roasted maté showed the highest content of bound phenolics (6415.1 µg/100 mg), whereas whole grain breakfast cereals (229.3 µg/100 mg) stood out among melanoproteins. The antioxidant capacity of melanoidins was strongly correlated with their bound phenolic compounds (r > 0.8522, p < 0.0001). We estimated that up to 10.7 g of melanoidins are daily consumed
