Formulation of Functional Yogurt by Cofermentation of Milk and Papaya Fruit
AbstractThis study was carried out to determine the potential of adding Fresh skinned papaya pulp (FSP) into yoghurt for the improvement of the functional properties of yoghurt and the resulting effects of adding PPF on the physicochemical and sensory properties of the product during a 30 days’ storage period at 6°C. Yoghurt samples A (Control), B, C, D and E were respectively produced at 0%, 5%, 10%, 15%, and 20% of milk incorporated with papaya fruit. Incorporation of PPF into the yogurt samples resulted in an increase in pH, proteins and carbohydrates and a reduction in titratable acidity as compared to the control. The microbial analysis showed no presence of coliform bacteria. The sensory evaluation result demonstrated significant differences in all the organoleptic attributes analyzed. Sample C with 10% incorporated papaya had the highest overall acceptability score.
