The distribution of antigenicity in rice grain

In this paper we tried to reveal the distribution of antigenicity in a rice grain. We determined total and salt soluble protein content and the antige n-binding capacity of salt soluble protein in various layer of a rice grain . Sail-soluble protein content was high in outer layer. and it was low and constant in inner layer. The antigen-binding capacity of salt soluble prote in was especially high in a layer near the surface of grain. The capacity w as remarkably reduced in inner layer of grain. The antigen-binding capacity of high-milled rice was reduced to around 4% of that of brown rice. There were some differences in the distribution of antigenicity of the rice grain among varieties, but the reductional effects of antigenicity by high-milli ng treatment were constant even among different varieties.
