Study on the Factors Influencing the Formation of Fusel Oil in Liquor by Solid Fermentation

The effects of fermenting power,saccharifying power,and proteolytic power on the yield of fusel oil in liquor by solid fermentation were studied and the results were as follows: fermentation rate would influence the formation of fusel oil and fast fermentation would result in low fusel oil yield,the enhance of fermenting power would effectively reduce fusel oil yield,and the adjustment of proteolytic power could also reduce fusel oil content in liquor.Furthermore,the harmony among fermenting power,saccharifying power and proteolytic power would achieve the minimum fusel oil yield.(Tran.by YUE Yang)
