Abstract

The major kernels$(7{\sim}10\;mesh)$ of naked barley were pearled to give an average yield for each pearling of about 5% flour, with 70% of the naked barley left as residual kernel. The contents of protein, fat and ash were in the highest in the fraction of 1,2 and 3, respectively. These fractions contained 1, 4 times of protein, 3.16 times of fat and 3.08 times of ash more than those values of original kernel. Residual kernels contained 62% of protein, 38% of fat and 35% of ash in the original kernel. Among minerals, the content of Ca, Na, Fe and Mn were in the highest in fraction 1 ; P, Mg and Zn in fraction 2 ; and K and Cu in fraction 3. Concentrations of these minerals were the lowest in the residual kernel. Magnesium showed the deepest concentration gradient, while iron was evenly distributed within the kernel.
