通过荧光染料尼罗红在激光共聚焦显微镜(CLSM)下记录的信号强度,研究了海藻酸对乳液中油脂在体内消化过程的影响。尼罗红仅对乳液中油脂具有染色作用,因而可以显示油脂的变化。结果表明,海藻酸在胃部能够保持乳液颗粒结构,但存在一定凝聚。而海藻酸在小肠中能明显抑制脂肪酶对油脂的水解。 The effect of alginic acid on the digestion of oil in emulsion was studied by the signal intensity recorded by confocal laser scanning microscopy (CLSM). Nile red only has a staining effect on the fat in the emulsion, which can show the change of fat. The results showed that alginate could maintain the emulsion particle structure in the stomach, but there was some aggregation. Alginate, however, significantly inhibits lipase hydrolysis by lipase in the small intestine.
