Staple food item in China and Japan Slowly becoming popular in the U.S. Soybeans http://www.biztrademarket.com/User/164746/bb/dscn5800_hp3.jpg
Soybeans • Good source of protein • Considered to be a complete protein • Noted to have an objectionable flavor: “painty” and “beany”
Soybeans Possible health benefits: May lower LDL cholesterol May reduce the risk of certain chronic diseases including cancer May promote bone health *Soybeans are a rich source of isoflavones which are known to have antioxidant properties. They are still under investigation for their role in bone health and prevention of cancer among other illnesses.
Found in the endosperm of guar beans Grown in India and Pakistan Guar Gum www.barryfarm.com/images/product/thickeners/guar.JPG
Guar Gum’s Characteristics • Non-gelling • Increases viscosity • Ability to bind with water • Stabilizer

Formed by grinding broken rice kernels Could be derived from brown or white rice http://www.goodnessdirect.co.uk/detail/211263b.jpg Rice Flour
Rice Flour’s Characteristics • No gluten-forming properties • Lacks elastic and cohesive properties • Needs another ingredient for substantial binding properties • Gritty texture
Uses of Rice Flour Baked goods Pancake and waffle mix Baby food
The purpose was to create a delicious, inexpensive, and nutritious soybean tuna patty. Group’s Purpose
Our Process: Day 1 • Manipulated the rice flour and soybean levels to create texture • Experimented without tuna water to improve texture • Experimented without guar gum to improve texture
Our Process: Day 2 • Experimented with soybean preparation to improve texture • Experimented with different spices to improve flavor
