| titleOfInvention | A kind of method of the enzymatic clarification starch octenyl succinate anhydride in ionic liquid |
| abstract | A kind of method of the enzymatic clarification starch octenyl succinate anhydride in ionic liquid, belongs to starch processing technique field.The principle of the invention is based on the acetic acid type ionic liquid by the use of high cation concentration as the efficient solvent environment of enzymatic clarification starch ester, makes starch solubilising and keeps lipase activity, significantly improves the enzymatic clarification efficiency of starch octenyl succinate anhydride.Present invention design has synthesized two kinds of ionic liquids：[the Me (OEt) of ionic liquid 1 2 Al Im] the Ac and [Me (OEt) of ionic liquid 2 3 Al Im] Ac, then with one of both ionic liquids as reaction dissolvent, add 10% common corn starch, the pre-gelatinized treatment 10min under the conditions of 100 DEG C, it is cooled to 50 DEG C of follow-up enzyme process reaction temperature, adding the octenyl succinic acid anhydride of starch on dry basis quality 3%, 10% lipase Novozym 435 carries out esterification 30min, product washs into cleaning solution anhydride concentration less than 0.3% through 95% ethanol precipitation, 40 DEG C of drying, crush, obtain the starch octenyl succinate anhydride product that substitution value reaches 0.014 0.019. |
