Patent Background

Priority Date:This application claims the benefit of priority of U.S. Provisional Application Number 60/837,331 filed on August 11, 2006.

Claim 1:A composition for making a gluten-free product, comprising a gluten-free gas-retaining polymer, and a gluten-free setting polymer.

Example 2: Hydrocolloid Treatment

Optimization of Example 2 resulted in 4 gluten-free bread prototypes.

GF Breadmaking Rules vs. ConventionalMade from a viscous batter that is high in water.

Mixing hydrates hydrocolloids, modified starches and emulsifiers, which thicken and hold the batter together.

Shorter proof times than normal because diffusion is faster in the batter and air cells are less stable.

Emulsifiers increase the stability of air cells.

The batter matrix retains air cells, but lacks strength and collapses if it contacts a solid surface.

Upon heating, yeast and chemical leavening and in turn expanding air cells yield ovenspring, which must occur quickly before the batter sets.

Film forming ingredients promote oven spring by improving batter strength and flexibility of the batter.

The batter sets as starch gelatinizes and proteins denature.Set-ability is highly dependent on plasticizer (sugar, water, etc.) content.

In the baked bread, hydrocolloids, starches and emulsifiers impart chewy and soft bread texture.

Flavors are added to the batter to enhance final bread flavor.Flavors compensate for gluten and the flavors that result from reactions between gluten and sugars.
