Chemistry, Texture, and Flavor of Soy

For centuries soy has served as an important and inexpensive source of high quality protein throughout the world, especially in Asia. Soybeans are now cultivated in large scale in North and South America, where they are mainly used for production of edible oil and animal feed. Part of the
defatted soy meal by-products are refined into functional ingredients for inclusion into various processed food products, including meat, dairy, wheat, beverage and snack food products. Therefore, the cÍnsumption of soy has increased tremendously in the Western countries in the last thirty-forty
years. More benefits of soy have spurred a new wave of demand for soy foods, not only in Western countries, but also in those countries which traditionally consumed soy. Growth in soybean production and utilization is also occurring in developing countrie s to help meet nutritional needs of those
populations. Despite the tremendous growth in the globalconsumption of soy, there are still many technological challenges that must be met to improve the food quality, nutritional and health promoting attributes of soy-containing foods. In particular, numerous flavor and textural challenges impact
the quality and consumer acceptability of soy foods. These flavor and texture properties as well as the nutritional and health-promoting attributeshis book will serve as a platform for future scientific and technological studies leading to improvements in the quality and acceptability of soy foods.
It is a culmination of a symposium titled Chemistry, Texture and Flavor of Soy, which was sponsored by the Agricultural and Food Chemistry Division of the American Chemical Society and held at the 236th ACS National Meeting in Philadelphia, PA, August 17-21, 2008. In this book, leading researchers
cover the following topics as they relate to the quality of soy foods and ingredients: the chemistry of soy and soy components, including isolation and characterization of bioactives and functional ingredients/compounds, texture aspects of soy and soy ingredients, including processing,
characterization and measurement by sensory and/or instrumental means, and flavor chemistry and analysis (sensory and instrumental) of soy and soy products/ingredients/components.
