摘要: 研究了制备玉米交联微孔淀粉的工艺条件,以交联微孔淀粉的吸水、吸油率作为考察指标,通过单因素和正交试验,考察温度、时间、酶用量、酶配比、淀粉乳浓度、pH值对交联微孔淀粉吸水、吸油率的影响,结果确定最佳酶解工艺条件为:温度50℃,时间24h,酶量2.3%,淀粉乳浓度18%,pH值5.0,酶配比1:8,所得交联微孔淀粉的吸水、吸油率分别为163.21%、134.20%。
关键词: 交联微孔淀粉, 吸水率, 吸油率
Abstract: The preparation of crosslinked porous cornstarch was studied and water adsorption and oil adsorption were investigated. Some factors, such as reaction temperature, reaction time, enzyme addition, enzyme combination, buttom sub- stance concertration and reaction pH were studied as the main factors for water adsorption and oil adsorption capacity. The single element and orthogonal test showed the optimum enzyme reaction condition are as follows: reaction temperature 50℃, reaction time 24h, enzyme addition 2.3%, buttom substance concertration 18%, pH 5.0 and enzyme combination 1:8. Under these conditions, the capacity of water adsorption is 163.21%, and the capacity of oil adsorption is 134.20%.
Key words: crosslinked porous cornstarch, capacity of water adsorption, capacity of oil adsorption
