Ueman Ryoshoku Seifunsho specialises in wagashi ingredients processed from rice and soy beans, including joshinko rice starch, shiratamako rice starch, and kinako soy bean flour. The company has succeeded in using its milling technology to process rice into flakes, making possible the production of â€œpankoâ€ from rice flour. These panko are made from 100% Japanese rice, with no secondary ingredients (e.g. yeast, shortening, salt) or additives. This unique product offers a distinctive crunch thatâ€™s quite different from standard wheat flour-based panko.
