The physicochemical profile of Dulce de Leche (DL) was determined by both routine analysis and others techniques (HPLC, GC–MS and ICP-OES). Seven Brazilian commercial brands were characterised for moisture content, protein, fat, ash, pH and titratable acidity, mineral content (sodium, potassium, calcium, and phosphorus), colour parameters and instrumental analysis (carbohydrates content and volatile compounds). Overall, extensive variability among all the parameters evaluated were observed, suggesting different operational procedures in the dairy factories along the DL processing. In this sense, an increase of intrinsic quality of DL is related closely the standardization of operational parameters using during the manufacture.
