The main objective of this study is to proceed an evaluation of the amount of total soluble solids (TSS) and the pH value in lactic drinks (yogurt and chocolate milk) commercialized in Teresina and consumed by children. Twenty lactic drinks were evaluated in this experiment with 3 repetitions of study case in each sample. The Brix degrees measurement was made by refractometry using an Abbé refractometer and the pH was evaluated using potentiometry. The medium content of TSS was in a range between 11,0 ºBrix and 22,0 ºBrix. Meanwhile the minimum maximum pH the medium values were 3,79 and 6,71. From this results what can be concluded is that a high concentration of TSS can be verified in lactic drinks, associated with a low pH may contribute to the development of cavity lesions and dental erosion in case of the excess consumption of this products by children.
