摘要
抗性淀粉是指在健康人体小肠中不被吸收的淀粉及其降解产物,这一生理学定义给其定量分析带来了困难。本文综述了抗性淀粉的体内和体外主要测定方法。体外测定法应模拟体内消化条件,并需要体内测定法的验证。McCleary等人的方法因简单可靠成为唯一被AOAC采用(AOAC方法2002.02)的食品抗性淀粉含量测定方法。
Resistant starch （RS） is defined as ＂the sum of starch and starch degradation not absorbed in the small intestine of healthy individuals＂. This physiological definition of RS raises a difficulty in proper analytical quantification of RS. The present review described main methods to measure RS both in vivo and in vitro. The in vitro method needed imitation in vivo conditions and to be directly validated by in vivo methods. The simple and reliable method of McCleary et al. is the only method accepted by the AOAC（AOAC method 2002.02）for determining the amount of RS in foods.
