Abstract
Exemplary embodiments provide oat fractions, and methods of producing the oat fractions, of the species Avena Sativa that has a concentration of total Avenanthramides that is from about 2 to about 25 wt. %, and up to about 30 wt. % or more, higher than the concentration before treatment with infrared energy. The higher concentration is achieved without treatment with enzymes or exposure to fungal agents to increase the concentration of total Avenanthramides. Instead, the enhanced concentration of Avenanthramides is achieved through exposure to infrared energy for a selected period of time.
Claims36
An oat fraction of the species Avena Sativa comprising a concentration of Avenanthramides higher than occurs naturally in said species, wherein the oat fraction is untreated with enzymes or fungal agents to increase the concentration of Avenanthramides, and wherein the oat fraction was treated by exposure to infrared energy.
A method of increasing an Avenanthramide concentration in an oat fraction, without treatment of the oat fraction with enzymes and without exposure of the oat fraction to a fungus, the method comprising the steps of:
- selecting an oat fraction derived from the species Avena Sativa;
- and
- exposing the selected oat fraction to infrared energy to increase an Avenanthramide concentration in the selected oat fraction.
