Amy's response:
Because of concerns around soy protein extracted with hexane, we have eliminated the use of any soy protein ingredient that uses hexane in its processing.
Only four products (some of our veggie burgers) out of over 170 products have ever contained soy protein concentrate. We have replaced soy protein concentrate in these products with organic tofu. Tofu production is similar to cheese making and uses no unnatural ingredients. To see our tofu being made check out this video: http://www.amys.com/about_us/our_kitchen.php#tofu
Our best selling burger, the California Burger, has never contained soy protein of any kind.
Amy’s remains a family owned business and we take great care to make healthful foods with organic ingredients. We welcome communication from our customers and invite you to visit us at http://www.amys.com
