Abstract
On mineral availability, it's important to clarify mineral distribution in food material. Using X-ray analytical microscope (XAM), we have investigate d each distribution of K and Ca in 5 cultivars of sweet potato. K was highl y distributed in the epidermis in contrast to high Ca content in cortex. Th e results from XAM analysis were compared with those of conventional quanti ty analysis such as ICP-AES. They were in good accordance with each other. From the results of ICP-AES analysis, we found that the epidermis contained much amount of Mg as well as K.
