以陕西关中小麦淀粉为原料,以制备食用级羧甲基淀粉钠为目的,研究了乙醇溶剂法生产过程中,原料配比、反应温度、反应时间等因素对产品性能的影响。最佳操作条件为:原料质量比淀粉:氯乙酸:NaOH=1:0.36:0.21,乙醇浓度85%,反应温度50℃,反应时间2.0h。
以陝西關中小麥澱粉為原料,以製備食用級羧甲基澱粉鈉為目的,研究瞭乙醇溶劑法生產過程中,原料配比、反應溫度、反應時間等因素對產品性能的影響。最佳操作條件為:原料質量比澱粉:氯乙痠:NaOH=1:0.36:0.21,乙醇濃度85%,反應溫度50℃,反應時間2.0h。
이협서관중소맥정분위원료,이제비식용급최갑기정분납위목적,연구료을순용제법생산과정중,원료배비、반응온도、반응시간등인소대산품성능적영향。최가조작조건위:원료질량비정분:록을산:NaOH=1:0.36:0.21,을순농도85%,반응온도50℃,반응시간2.0h。
Taking wheat starch of Guanzhong in Shaanxi as raw material to prepared sodium carboxymethyl starch used wheat starch, the effects of raw material ratio, reaction temperature and reaction time during the production with ethanol solvent method were studied. The best conditions were that the ratio of starch : chloroacetic acid : NaOH was 1 : 0.36 : 0.21, 85% ethanols concentration, 50℃, and 2.0 h.
