  • METHOD FOR PREPARING GLUCOSE FROM STARCH SUGAR BY USING ACIDOTHERMUS SP.-DERIVED DEBRANCHING ENZYME HAVING HEAT RESISTANCE AND ACID RESISTANCE, AND GLUCOSE PREPARED THEREBY
    Publication number: 20190136277
    Abstract: The present application relates to improving the production yield of glucose to be prepared by using starch sugar as a raw material and using an Acidothermus sp. derived enzyme. The present application can replace an acid saccharification method, which produces a bitter taste through a hydrolysis reverse reaction, and, compared to a enzymatic saccharification method in which a conventional debranching enzyme is used, has an advantage of enabling costs to be reduced since a relatively high yield can be ensured by reducing side reactions of a saccharification reaction.
