This study was conducted with the objective of elaborating dietetic formulations, nutritionally balanced, with osmolality control, easy preparation and low financial cost. The diets were prepared mainly with common foods, added by maltodextrin, calcium caseinate and mineral supplements, as follows: 1) milk plus fruits; 2) vegetable juices plus protein supplement; 3) milk porridge plus protein supplement; 4) infant adapted formula; 5) concentrated fruit extract. The flow was observed by getting the formulations through tubes with internal diameter of 2.1 mm and the stability was checked by stocking the solutions in a minimum period of 3 hours. The osmolality was determined by cryoscopy, measuring the relative depression of steam pressure of the solutions. Formulations with osmolality between 250 and 400 mOsm/kg and caloric density between 0.60 and 1.08 Kcal/ml were obtained. Low cost diets, easy prepared, nutritionally balanced and with definition of their compounds were achievable.
