Study on processing technology of nutritional composite cereal beverage
With glutinous rice,millet and sweet corn as raw material,according to the different proportion of the composite grain production fermentation fermented beverages.By single factor experiment,and the ratio of material to water proportioning,fermentation temperature,fermentation time on alcohol,residual sugar amount and acidity and other sensory indexes of influence.Through orthogonal test,to determine the best fermentation compound grain beverage technology conditions.The best get composite grain drinks fermentation conditions for glutinous rice:millet:sweet corn for surely:20 to 30 ℃,fermentation temperature,fermentation time 4d,fermentation temperature 30 ℃,the ratio of material to water 1:1,appropriate amount of sugar to 4％.Finished beverage alcohol 2％,residual sugar 8％,acidity(quantity of pH)4.5.Through experiments,no precipitation obtained products without suspended solids;Bouquet mellow coordination,colour and lustre is has milk-white slightly paler clear and transparent,unique style,it is pure intermixed;Keep the grain nutrition and medicinal value,as a kind of natural,health beverages cereals.
