Biological Activity

[Description]:

ι-Carrageenan (Viscarin SD 309) is a biochemical reagent. ι-Carrageenan can be isolated from Eucheuma serra or red algae H. musciformis and S. filiformis. ι-Carrageenan has potential application in protein emulsion flocculation and stability[1][2][3][4].

包含 ι-Carrageenan (16.67-100% 分散在混合物中) 的膜显示出聚合和低透明度[1]。 ι-Carrageenan (0.088 wt% 和 0.13 wt%) 在 PH=6 时以剂量依赖的方式改善牛血清白蛋白 (BSA) 乳液的液滴尺寸分布[3]。 ι-Carrageenan (0.0011、0.011 和 0.22 wt%；8 d) 在 PH=9 时对 BSA 乳液的表观平均液滴尺寸影响较小[3]。 ι-Carrageenan (0-0.15 wt%) 在 PH=3 时以剂量依赖的方式增加 β-乳球蛋白 (β-Lg) 乳液的平均粒径[4]。 ι-Carrageenan (0-0.16 wt%；7 d) 在 PH=6 时显示出良好的 β-Lg 乳化稳定性[4]。
