Food protein product, gluten protein, was chemically modified by varying levels of sodium stearoyl lactylate (SSL); and the extent of modifications (secondary and tertiary structures) of this protein was analyzed by using Raman spectroscopy. Analysis of the Amide I band showed an increase in its intensity mainly after the addition of the 0.25% of SSL to wheat flour to produced modified gluten protein, pointing the formation of a more ordered structure. Side chain vibrations also confirmed the observed changes.
食品蛋白质产品,即面筋蛋白,通过改变不同水平的硬脂酰乳酸钠(SSL)进行化学修饰;并通过使用拉曼光谱分析该蛋白质的修饰程度(二级和三级结构)。酰胺 I 带的分析表明,其强度主要在向面粉中添加 0.25%的 SSL 以生产改性面筋蛋白后增加,表明形成了更有序的结构。侧链振动也证实了观察到的变化。
