SoyInfo Center

Founding
In October 1972 Willam Shurtleff and Akiko Aoyagi began full-time research on soyfoods in Japan while writing The Book of Tofu. In August 1976 they founded SOYINFO CENTER (named Soyfoods Center until 31 Dec. 2006) in California. We are authors.

Our Mission
To be the world's leading source of information on soy, especially soyfoods, new industrial uses, and history, in electronic database, online and printed book formats. To provide the information needed to transform soybeans into food products. To publish a history on every major subject related to soybeans and soyfoods. We do not sell books - or anything else - on this website..

Book Sales
Our printed and bound books have sold more than 830,000 copies. These include three popular books (The Book of Tofu, The Book of Miso, The Book of Tempeh), three production manuals (Tofu & Soymilk Production, etc.), 40 comprehensive bibliographies, plus market studies, histories and books of color graphics.

Building an Industry
Our three production manuals have played a key role in starting more than 450 soyfoods businesses in the United States, Europe, Latin America, and Africa .
