Abstract
Abstract A method is disclosed for making a highly expanded, porous oat cereal product having a density of below about 12 ounces per 121.5 cubic inches comprising the steps of: a. classifying an oat flour to separate out a low β-glucan oat flour with a β-glucan content of less than about 3.3%, b. cooking a mix comprising the low β-glucan oat flour wherein the low β-glucan oat flour comprises at least about 55% of cereal flour in the mix, c. expanding and shaping the cooked mix into a shaped cereal product, d. heat setting the shaped cereal product, and e. drying the heat seat cereal product to a moisture content at which it is structurally stable.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
168 words
A method of making a highly expanded, porous oat cereal product comprising the steps of: a. classifying an oat flour by separating particles of the flour into at least two classes of differing particle size to separate out a particle size having a low beta-glucan oat flour with a beta-glucan content of less than about 3.3%; b. cooking a cereal flour mix comprising the low beta-glucan oat flour in a cooker-extruder wherein the low beta-glucan oat flour comprises at least about 55% of cereal flour in the mix and the mix has a moisture content of about 25% to 40%; c. expanding and shaping the cooked mix into a shaped cereal product by expressing the mix from the cooker-extruder under expanding conditions; d. immediately heat setting the expanded, shaped cereal product; and e. drying the heat set cereal product to a moisture content at which is is structurally stable to obtain a porous oat cereal product having a density or below about 12 ounces per 121.5 cubic inches.

Claim 3
Dependent Claim
20 words
The method of claim 1 wherein the low β-glucan oat flour has a β-glucan content of less than about 2.2%.
