Abstract

Chemical composition, microbiological and sensory properties of five different yoghurt prepared from blended cow and goat milk were analyzed. The result of the chemical analysis indicated that, the water percentage, pH of the yoghurt samples were not significantly different (P>0.05). The total acidity of yoghurt samples, however, were significantly different (P<0.05). Microbiological analysis showed that, yoghurt prepared from 75% goat milk had the highest bacterial population of log 8.8692 cfu/g, while yoghurt made of 100% cow milk showed the lowest bacterial load of log 8.3979 cfu/g. The result of sensory analysis showed that, yoghurt made from 100% goat milk obtained the highest score in colour and aroma of 6.9 and 7.0 respectively, though they were not significantly different (P>0.05). Analysis of texture showed that, yoghurt made of blended cow and goat milk were significantly preferable (P<0.05). Taste and overall acceptability of yoghurt made from blended 75% cow and 25% goat milk showed the highest score and were significantly different (P<0.05), compared to yoghurt made from 100% cow milk. Keywords: microbiological, chemical, sensory, yoghurt, cow milk, goat milk
