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°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 8CFU/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.
