| 摘 要： | 以黑曲霉(Aspergillusniger)直接发酵法制备甘薯微孔淀粉,在单因素研究基础上,采用正交试验优化发酵工艺条件。实验结果表明,在30℃、摇床转速170r/min条件下,初始pH为5.5、3%豆饼粉、3%接种量、添加初始马铃薯生淀粉10%、前期发酵40h后,补加15%生淀粉,后期发酵45h,制得微孔淀粉吸附性能较佳;通过交联反应可提高微孔淀粉结构和吸附性能。 |
| 关 键 词： | 黑曲霉 微孔淀粉 甘薯淀粉 |

| Abstract: | Microporous sweet potato starch was prepared directly by Aspergillus niger fermentation. In the foundation of monofactorial research,adopting orthogonal experiment to optimize process conditions of microporous starch. Results showed that,absorbability of microporous sweet potato starch was optimized,when temperature 30℃,rate of rotation 170 r/min,initial pH 5.5,adding initial raw sweet potato starch 10%,bean powder 3%,inoculation 3%,pro–fermentation 40 h,additional raw starch 15%,post–fermentation 45 h. The absorptive and structural properties of the microporous starch can be enhanced by crosslinked. |
