摘要
通过美拉德反应对荞麦蛋白进行改性,对荞麦蛋白-木糖接枝物的制备及其性质进行研究。在湿热条件下,利用美拉德反应制备荞麦蛋白-木糖接枝物。通过正交试验优化接枝物的制备条件,荞麦蛋白与木糖按1∶5的质量比、在50℃下反应120min,接枝度可达到49.24%。性质测定表明,接枝物的溶解度较荞麦蛋白提高了约25%,乳化性提高了约30%,乳化稳定性提高了约11%。
The production and characteristics of buckwheat protein（BWP）-xylose conjugate was studied by the Maillard reaction in the condition of moist heating.The optimal condition for conjugate production was as follows：acetone ratio of 1∶5,reaction temperature at 50℃ for 120 min,and the degree of graft arrived 49.24%.The solubility of BWP-xylose was increased by about 25%than BWP and the emulsibility was improved about 30% and emulsion stability was improved about 11%.
