Abstract

The pH, acidity, viscosity, viable cell counts of lactic acid bacteria, and Hunter color value of yoghurt and also over-run and melting-down of yoghurt ice cream added with rice or puffed rice powder in instead of sugar were investigated. For the pH of yoghurt and ice cream, the control’s was higher than others’. The pH of rice powder and short grain was higher than that of puffed and long rice powders, respectively. Yoghurt acidity was consistent with the pH. Higher viscosity of yoghurt and over-run of ice cream were observed in the puffed rice powder with more gelatinization and the short rice powder with more amylopectin. Yoghurt and ice cream of the long rice powder showed higher viable cell counts than others. Lower Hunter “L” and “a” values of the puffed rice powder may be due to high temperature and pressure. Lower melting-down of higher over-run samples (p<0.05) might be caused by air insulation. Rice powder and puffed rice powder could be a good substitute for table sugar in yoghurt and ice cream production.
