Corn fiber for the production of advanced chemicals and materials |
摘要 |
The invention provides a method of obtaining a cellulose material from corn fiber wherein the method comprises the steps of: (a) heating a mixture of corn fiber and a liquid; (b) contacting the mixture of step (a) with a protease enzyme, thereby providing a proteolyzed corn fiber and a liquid; (c) separating the liquid from the proteolyzed corn fiber; (d) contacting the proteolyzed corn fiber at least once with an alkaline extractant, thereby providing an insoluble cellulose material and a first liquid comprising arabinoxylan; (e) separating the insoluble cellulose material from the first liquid comprising arabinoxylan at a temperature of at or above about 60° C.; and (f) rinsing the insoluble cellulose material to remove essentially all alkali, thereby providing a cellulose material having a cellulose content of at least about 50% and consisting essentially of cellulose I. Cellulose esters and ethers are also prepared from the derivatizable cellulose prepared according to the methods herein. |
