Circular dichroism spectroscopy measurements also reveal that the ordered structure content of α-helical and β-structure of ovalbumin decrease, and the unfolded random structure is enhanced with increasing pressure; While the existence of dextran sulphate to the native ovalbumin, there are no apparent change on the secondary structure of ovalbumin; It seems same to glycinin.

圆二色性光谱分析表明，经超高压处理后，鸡蛋清蛋白分子中规则的二级结构减少，而部分规则的二级结构和无规卷曲含量增加。加入硫酸右旋糖苷的鸡蛋清蛋白溶液经超高压处理后其二级结构中各部分的含量变化不大：对于大豆豆球蛋白，加入硫酸右旋糖苷后，大豆豆球蛋白分子经超高压处理后其有序结构的减少及无规卷曲的增加都相对减缓。

Based on membrane extraction and helical tube technique, the mass transfer performance of some membrane modules with a different helically wound hollow-fibre was studied with the system of 30%TBP-water and phenol as the solute.
