摘要
通过单因素和L9(34)正交实验研究了羧甲基纤维素(CMC)与魔芋葡苷聚糖(KGM)的复配比例、搅拌时间、温度、p H及放置时间等因素对CMC/KGM复配溶胶粘度的影响。结果表明:CMC与KGM复配具有协同增稠效应;随着放置时间的延长,CMC与KGM复配溶胶粘度的稳定性优于单体KGM溶胶;CMC与KGM复配溶胶的最佳制备条件:CMC与KGM的质量比为2∶8(复配溶胶的总浓度为10g/L),搅拌时间为4h,温度为30℃,p H为7,其粘度值为38063m Pa·s。
The effect of weight ratio,stirring time,temperature,p H,and deposited time on its viscosity property of CMC-KGM sol were investigated systematically through single factor and L9（34） orthogonal tests. The results indicated there was a synergistic thickening effect between CMC and KGM. An excellent stability regarding the viscosity of the CMC-KGM sol was found with the extension of deposited time,comparing with KGM sol. The optimal conditions for the preparation of CMC-KGM sol were as follows ：the mass ratio of CMC to KGM was2∶8（the initial concentration of CMC-KGM sol was 10g/L）,stirring time 4h,temperature 30℃ and p H at 7,respectively. Besides,ultimately,it was up to the viscosity of 38063 m Pa·s with respect to synthetic system.
