4. Conclusions
By comparing the fermentation characteristics under same
experimental conditions, significant differences (p < 0.05) were
observed between some individual rice cultivars on the chemical
properties such as pH value, total acidity, amino acidity and
reducing sugar, alcohol yield, fusel alcohols and ethyl acetate,
sensory properties and suspension stability. Out of 18 rice cultivars,
