Soybean is known to have various functions, for example, modulating lipid metabolism, antioxidative function and anticancer effect. But soybean is hard of digestion, so it is required to establish the manner of cooking soybean for its functions. In this study, we examine the dietary effect of various diameter of soybean powder on lipid metabolism and immune function of male Sprague-Dawley rats. Diameter of each soybean powder was 80 (Coarse), 45 (Middle) or 5 (Fine) μm. As results, Serum IgA level significantly decreased in Fine group. Decreasing of serum IgA level was also obtained in Coarse groups. Immunoglobulin productivity of spleen lymphocyte was increased in Middle group. Shorter diameter of soybean powder decreased the productivity of IgA in mesenteric lymph node lymphocyte. There were no effects of soybean powder on serum lipids parameters dependent on their diameter. Liver phosphatidylcholine hydroperoxide and α-tocopherol levels were decreased by soybean powder feeding independent on their diameter. Docosahexaenoic acid level in liver phospholipids increased by the feeding of soybean powder, and Docosahexaenoic acid level increased depending on the diameter of soybean powder. These results suggested that soybean must be milled to use its function fully, especially n-3 fatty acid contained in soybean as α-linolenic acid.
