摘要：
An aqueous extract containing .alpha.-1,6 and .alpha.-1,4 carbohydrases obtained from diastatic malt is treated with an adsorbent to remove yeast lethal factors and can be used to produce a superattenuated low calorie beer. The enzyme-containing extract preferably is introduced into a pitched aerated wort during fermentation. Crude aqueous extracts of diastatic malt cannot be used because they contain factors lethal to yeast which adversely affects the yeast viability throughout the fermentation.
