| 摘 要： | 为了有效脱除魔芋粉中的生物碱，从而扩大其应用范围，本研究开发出超微粉碎、酶处理、微波辅助乙醇萃取等集成技术。结果表明，魔芋粉目数在160 目时，经过以上集成技术处理，其生物碱基本脱除干净，且处理后的魔芋粉溶胀性、亮度值相对于对照组有提高，黏度稳定性几乎不变。其形成的水凝胶网络结构稳定、抗剪切变形能力强。说明此技术可以用于制备脱敏魔芋粉，且还可以改善魔芋粉的部分理化性质。 |

| Abstract: | In this study, we developed an integrated procedure using ultrafine grinding, α-amylase treatment and microwaveassisted extraction to prepare konjac flour with expanded applicability by removing alkaloids. The results indicated that alkaloids could be removed almost completely from 160-mesh konjac flour by the integrated methods. Compared with the control sample, the treated konjac flour had higher swelling ability and luminance value and also had a stable hydrogel network structure and a high ability of shear deformation resistance, but the viscosity stability almost remained constant. Therefore, this integrated procedure can be used to prepare alkaloid-free konjac flour with improved physicochemical properties. |
