For Results & Discussion , The soy-yoghurt produced was creamish in color and has a beany flavor. Its pH value (5.2) indicates acidity. It was observed that the soy-yoghurt produced is more acidic than the soymilk from which it was gotten due to the effect of fermentation by the lactic acid-producing bacteria (LAB) that converted the lactose in the soymilk into lactic acid. The high acidity of the soy yoghurt makes it a poor breeding site for pathogenic microorganisms. A comparison of the soy yoghurt produced by fermenting soymilk using a bacteria culture of lactobacillus isolated from nunu with commercial diary yoghurt shows that soy yoghurt produced contains more proteins and moisture but less fat as presented in Table 1. The high amount of protein in the soy yoghurt was due to the fact that soybean is a proteinous food.
