一般描述

类胡萝卜素是水果和蔬菜中天然存在的一类重要色素。在类胡萝卜素中,β-胡萝卜素具有最大的维生素A原的潜力,并具有降低癌症、心血管疾病和黄斑变性风险的作用。食物中β-胡萝卜素的低吸收主要是由于其低水溶性和差的化学稳定性。β-胡萝卜素和可消化脂质丰富了其生物可及性。乳液或纳米乳液包封可有效地实现亲脂性β-胡萝卜素的递送,并提高其生物利用度。β-胡萝卜素具有抗氧化潜力,可减少噪音引起的听力损害和黄斑变性的进展。

应用

β-胡萝卜素已被用于:
  • 生成纳米乳液以评估其生物利用度潜力
  • 作为标准品,使用高效液相色谱(HPLC)对血液和皮肤样品中的β胡萝卜素进行评估,
  • 作为幼鼠体内维生素A的膳食补充剂,并通过HPLC进行测定
  • 作为小鼠的膳食补充剂,以减少听力损害和毛细胞损伤

生化/生理作用

维生素原 A,即 β-胡萝卜素能分类作为抗氧化剂的最重要的原因就是它可以在体外抑制自由基引发的过氧化。然而,它在体内究竟表现为抗氧化剂或是促氧化剂却取决于细胞环境。它可以降低许多癌症的发病率,却会增加吸烟者患肺癌的几率。
