Study on Alcohol Fermentation Technology of Sugarcane Juice Separated by Stainless Steel Membrane
The effect of fermentable sugar,pH and inoculation amount on alcohol fermentation process of sugarcane juice was investigated,and the fermentation liquid of sugarcane juice was analyzed and evaluated.The results showed that the turbidity value of the juice separated by stainless steel membrane diameter of 0.02 um could be reduced to 0.4 NTU,and the alcohol content could reach 9.9%under the conditions of fermentation with fermentable sugar content 16%,pH 4.5,inoculation amount of 8%and 28℃ for 7 days.The retention rate of flavonoids in fermented wine body was more than 99%,and it had good free radical scavenging ability.The wine has a special sugarcane aroma,brown color,clear and bright,trace colloidal precipitate suspended matter,mellow inlet.It can provide technical reference for sugarcane juice fermentation to produce high quality nutritive sugarcane fruit wine.
