This study was carried out to investigate the effect of beany flavor elimination and the acceptability of tofu prepared with blanched soybean. The results were as follows: 1. The content and me total protein of soymilk prepared with blanched soybean were decreased comparing with those of soymilk prepared with raw soybean. But the yield of tofu was not changed by blanching the soybean. 2. The beany flavor(hexanal, 1-hexanol, and pentanoI) was decreased but the toasted nutty flavor(ethanol and propanol) were increased by blanching the soybean. 3. By heating of soymilk, most of volatile compounds was disappeared, but ethanol, hexanal and 1-hexanol were remained. The hexanal content of tofu prepared with raw soybean was eleven times higher than that of tofu prepared with blanched soybean. 4. The color of tofu prepared with blanched soybean was more yellower than that of control group. At the lower temperature of blending, the texture of tofu was more smooth and elastic. 5. The tofu prepared with blanched soybean was more tasteful.
