| titleOfInvention | Enzymolysis method of starchy material and preparation method of citric acid |
| abstract | The invention relates to an enzymolysis method of a starchy material. The method comprises the steps of: (1) mixing a starch slurry obtained from a starchy material with part of enzymes so as to obtain a mixture, contacting the mixture with steam so as to make the temperature of the steam contacted mixture ranging from 75 to 95DEG C, under which the mixture is maintained for 30-90min; (2) contacting the steam contacted mixture in step (1) with steam again so as to make the temperature of the steam re-contacted mixture ranging from 100-120DEG C, under which the mixture is maintained for 1-10min; (3) cooling the steam re-contacted mixture to a temperature of 80-90DEG C, and mixing the cooled mixture with the residual enzymes for enzymolysis. The invention also provides a preparation method of citric acid. The methods provided in the invention provides a solution to the problem of high content of residual starch in an enzymolysis product (liquefied fluid), and can effectively enhance citric acid yield and reduce grain consumption, thus lowering the production cost of citric acid. |
