    摘要:

    为了明确影响乳液体系中β-胡萝卜素生物可给率的因素,作者通过构建体外消化模型及体外淀粉消化酶、脂肪酶及胆盐缺失3种特殊消化模型,对以辛烯基琥珀酸(OSA)改性淀粉为乳化剂的β-胡萝卜素乳液的生物可给率进行研究。结果显示,不同消化模型中β-胡萝卜素生物可给率的大小顺序为:完整消化模型>淀粉消化酶缺失模型>胆盐缺失模型>脂肪酶缺失模型。因此,当乳化剂消化、油脂消化和胆盐胶束化中任一进程被抑制时,乳液中β-胡萝卜素的生物可给率均降低。且这三者对乳液中β-胡萝卜素生物可给率的影响程度如下:脂肪消化>胶束化>乳化剂消化。

    Abstract:

    In order to investigate the parameters affecting the bioaccessibility of β-carotene in emulsion system,in vitro digestion model and three special digestion models(one without starch hydrolases,one without lipase and one without bile salts) were established to investigate the bioaccessibility of β-carotene emulsions stabilized by octenyl succinic anhydride(OSA) modified starches. The results showed that the bioaccessibility of β-carotene in four digestion models reduced in the following order:the complete model > the model without starch hydrolases > the model without bile salts > the model without lipase. It could be concluded that the bioaccessibility of β-carotene would decrease when one of the three processes of starch digestion,lipolysis or micellization of bile salts was inhibited. And the influence degree of these three factors on β-carotene bioaccessibility decreased in the following order:lipolysis > micellization > digestion of emulsifiers.
