摘要：
Complete separation of fermentable and non fermentable carbohydrates of up to 15 glucose units in wort, mashed malt and beer was obtained in 40 minutes by direct injection on a NH2 column and an HPLC-ELSD apparatus. The results were comparable with those found with the official HPLC-RI procedure and with chemical determination with Fehlung's reagent. In Italian wort and mashed malt, about 88% of the total carbohydrates are fermentable, while in beer only 29% are fermentable.
