从柑桔皮同时制取乙醇和橙皮甙的新方法

A New Method of Producing both Ethanol and Hespridin from Citrus Peel

在加入1.0％生石灰粉末的条件下直接压榨柑桔皮提取榨汁，经酸化，表观糖度为11～14°Bx,可直接用于发酵制取乙醇，减少工序及能耗，提高经济效益；以饱和石灰水浸泡柑桔皮渣提取橙皮甙粗产品，并用1％NaOH和50％乙醇混合溶液进行重结晶，提高纯度，工序简单，成本低，产率高，经济效益和环境效果显著。

Under the condition of adding quick lime powder(1％),the citrus peel juice can be made by the method of directly pressing.The apparent sugar degree of which' is 11°-14°Bx after acidification.This juice can be directly used to made ethanol by fermentation,and it can reduce the working procedures and energy consumption, and raise the economic benefit. By soaking the pressed dregs of citrus peels in the saturated lime water, the rough hesperidim can be abstracted, and recrystallized by the mixture of sodiumhy droxide (1％) and ethanol solution (50％)to improve its purity.(The working procedure which is simple and low-cost, has notable economic efficiency and enviornmental benefit.)
