The existence of dextran sulphate to the native ovalbumin leads to decrease about 60％ in fluorescence intensity following high pressure treatment. Complexation of polysaccharide with ovalbumin seems to protect the protein against pressure induced conformational change and aggregation; The presence of τ-carrageenan in glycinin solution is also found to protect the protein against pressure.

经超高压处理后，加入硫酸右旋糖苷的鸡蛋清蛋白溶液中的ANS荧光强度显著降低，降低约60％；这表明，硫酸右旋糖苷的加入可以和鸡蛋清蛋白相互作用，从而在超高压处理中起到稳定蛋白质天然构象的作用；对于大豆豆球蛋白溶液而言，ι-角叉菜胶的加入有维持高压下大豆豆球蛋白构象稳定性的作用。
