| 摘 要： | 采用单因素试验结合正交试验对食品用玉米淀粉磷酸酯的干法制备进行可行性研究。该工艺旨在解决传统湿法制备时,需洗涤和干燥,以及由此引起的环境污染及高能耗问题。通过控制三聚磷酸钠添加量使反应体系中总磷含量低于0.4%(干基),反应后可不进行洗涤和干燥,直接得到成品。在单因素试验基础上,通过正交试验确定生产最佳工艺条件为:三聚磷酸钠0.4%(干基)、固相酯化温度130℃、固相酯化时间3 h、反应体系pH 6.89。将干法制得产品与湿法生产玉米淀粉磷酸酯进行比较,在取代度(degree of substitution,DS)、pH、糊透明度和冻融稳定性方面性质较为接近。

| Abstract: | The feasibility of the preparation of corn starch phosphate ester by dry process was studied by single factor experiments and orthogonal experiment.The process can avoid environmental pollution and high energy consumption from conventional washing and drying process effectively.The total phosphorus content,lower than 0.4%(dry base),in reaction system was controlled by the amount of sodium tripolyphosphate.A desired end product was prepared without the process of washing and drying.On the basis of single fac... |
