Abstract: The objective of this work was to develop a natural yogurt utilizing the resultant whey of a "coalho" cheese production, assaying different processes of pasteurization and powdered milk concentrations. The yogurt submitted to 90 degrees C/5min with 8 and 10% of powdered milk achieved the highest grade on sensorial analysis, with no significant difference ( P > 0,05). Products were characterized as integral, attended the request for protein, and supplied over 15% of the daily feed intake of calcium for children aged 1 to 10, characterizing it as calcium enriched. In both formulations, the pH decreased from 4.6 to 4.2 approximately and the acidity increased from 0.7g to 1.0g lactic acid/100g of product during 28 days of storage. There was no contamination by S. aureus, fecal coliforms, molds and yeasts. The counting of lactic bacteria varied from 5.6x10(9) to 8.0x10(8) CFU/g during shelf life, suggesting the promotion benefits from this probiotic product. It was concluded that whey utilization for yogurt production is a viable alternative to increase economic, nutritional, and functional value.
