摘要: 采用三氯氧磷(POCl3)为磷酸化试剂,制备玉米磷酸化改性蛋白并测定了其功能性质。与原玉米蛋白相比,磷酸化改性蛋白的溶解度、乳化能力和乳化稳定性、发泡性和发泡稳定性、持水性等功能性质均得到了提高;红外光谱分析表明,蛋白质肽链上引进磷酸根基团。

Abstract: Corn gluten protein was phophorylated with various degrees by POCl3, and changes of functional properties were determined. Results showed that phosphorylation caused significant increases in solubility, emulsification, foam and water absorption capacity. The FTIR spectrum indicated that phosphoric acid radical groups were introduced in protein chain.
