We have shown previously that sorghum is highly digestible in the rat. However, other workers have shown that sorghum is much less digestible than wheat, maize, and rice in young children. Because the rat does not show these digestibility differences, we developed an empirical pepsin digestion method, first reported in 1981, which simulates the digestion values found in children. In this report the method has been improved and used to analyze wheat, maize, rice, millet, and sorghum and certain processed samples of millet and sorghum. The pepsin digestion values parallel those found in children for wheat, maize, rice, and sorghum. In addition, a processed sorghum product that gave a high digestion value in children also gave a high value with the in vitro pepsin method.
我们之前已经证明,高粱在大鼠体内的消化率很高。然而,其他研究人员发现,高粱在幼儿体内的消化率远低于小麦、玉米和大米。由于大鼠没有表现出这些消化率差异,我们开发了一种经验性的胃蛋白酶消化方法,该方法于 1981 年首次报道,可模拟儿童体内发现的消化值。在本报告中,该方法得到了改进,并用于分析小麦、玉米、大米、小米和高粱,以及小米和高粱的某些加工样品。胃蛋白酶消化值与小麦、玉米、大米和高粱在儿童体内的消化值相吻合。此外,一种在儿童体内消化值较高的加工高粱产品,在用体外胃蛋白酶法测定时也得到了较高的值。
