摘要: 通过共振光散射法(RLS)、可见光吸收光谱法和差示扫描量热法(DSC)研究了B-藻红蛋白(B-PE)分别与海藻酸钠和明胶形成的复合物的稳定性.结果显示:B-PE/明胶和B-PE/海藻酸钠复合物的RLS强度随着明胶、海藻酸钠浓度的增加而增强;两种复合物的光热稳定性明显高于B-PE,而B-PE/明胶的光热稳定性又高于B-PE/海藻酸钠,这说明明胶与B-PE之间发生的相互作用明显强于海藻酸钠.

Abstract:

The stabilities of B-phycoerythrin (B-PE)/sodium alginate and B-PE/gelatin complexes were inVestigated by means of the resonance light scattering (RLS), the visible absorption spectroscopy and the differential scanning calorimetry (DSC). The results show that the RLS intensities of the two complexes both increase with the concentrations of sodium alginate and gelatin, respectively, and that B-PE has a stronger interaction with gelatin than with sodium alginate because the light and thermal stability of B-PE/sodium alginate is higher than that of B-PE but lower than that of B-PE/gelatin.
