Abstract
A simple and efficient method for the production of a stable, clear and high-potency oat extract, containing avenanthramide, is disclosed. The method employs the use of a differential dissociation constants and ultra filtration to stabilize extract, prevent the loss of functional activity as an anti-irritant and anti-oxidant.
Claims9

- a. milling whole oats;
- b. extracting the resulting oatmeal with a solvent “comprising water and a primary or a secondary alcohol”;
- c. adjusting the pH of the resulting oat extract to <4.0 ;
- d. membrane filtration of the oat extract with a pH <4.0 through a membrane <104 MWCO.
