【摘要】 本研究证明了类胡萝卜素在肠道内的被动吸收机制,对不同动物肠道内环境进行了检测,结果表明不同动物的肠道内环境有较大的差异。对差异较大的因素(如pH值、胆盐浓度、游离脂肪酸等)进行了一系列的研究,发现这些因素对动物吸收β-胡萝卜素有明显的影响。因此首次提出了肠道内环境控制动物吸收胡萝卜素的假说。更多还原

【Abstract】 This study aims to explore the potential factors resulting in selective uptake and deposition of carotenoids by animals. The results showed that absorption mechanism of carotenoids was passive. There were significant differences in the intestinal environment between different species, such as, pH, bile salt content, free fatty acid composition. The results also showed that these intestinal factors affect absorption of carotenoids. Therefore the hypothesis was put forward that the absorption of carotenoids was controlled by intestinal environment in the first time.更多还原
