  • Process for preparing carbohydrates from vegetal juice
    Patent number: 4544558
    Abstract: A process for producing carbohydrates from vegetal juice comprises extracting a vegetal juice from raw vegetal material, filtering the vegetal juice to remove material suspended therein, subjecting the resultant vegetal juice to an enzymatic reaction which consists of four stages in the following sequence. The vegetal juice in a first stage is admixed with a mixture of 3.2.1.4-.beta.-1,4-glucan glucanhydrolase and 3.2.1.15-poly-.alpha.-1,4-galacturonic glucanhydrolase, then the vegetal juice is admixed with 3.2.1.20-.alpha.-D-glucoside glucohydrolase. In the second stage the vegetal juice is admixed with 3.2.1.20-.alpha.-D-glucoside glucohydrolase; in the third state the vegetal juice is contacted with 3.2.1.21-.beta.-D-glucoside glucohydrolase, 5.3.1.4-L-arabinose-ketol-isomerase and 5.3.1.5-D-xylose-ketol-isomerase; and in the fourth stage the vegetal juice is admixed with 3.2.1.1-.alpha.-1,4-glucan-4-glucanhydrolase.
