Production and processing of soybeans and nutrition and safety of isoflavone and other soy products for human health.
Functional foods are intended to help consumers reduce or manage the risks for certain diseases while maintaining body function and structure. Functional foods are regulated differently depending upon the country. For example, the United States has not defined the term functional food in regulation. Thus, functional foods are treated just like conventional foods for obtaining regulatory safety approval. However, the sales of soy products, soy-enriched foods, and dietary supplements have grown tremendously during the past 3 years because of the increasing consumer awareness of soy as a healthy food ingredient. Isoflavones in soy are believed to have preventive effects for several hormone-dependent diseases, mainly due to their weak estrogenic activity. This mini-review discusses some of the important issues to be considered in using soy and isoflavone products as health foods, including production, composition, products, and processing of soy products, and the fate of isoflavones during processing, their bioavailability, and safety. Some of these issues may affect the choice of raw or basic material sources, processing conditions, quality control procedures/measures, and marketing strategies for both soy-based foods and isoflavones.
