ABSTRACT:
Methods of treating dehulled or hull-less oat, i.e. oat groats, to produce oat pearlings, oat flour and oat bran products are described. Oat groats are abrasion milled to remove up to 15% by weight and produce pearled oat groats and pearlings. The pearlings are extracted sequentially with aqueous ethanol and hexane to produce an anti-irritant and a light oat oil, or with hexane to produce a dark oat oil and lipase. The pearled oat groats are steeped in an aqueous medium for up to 4 hours and then macerated to produce an enriched oat bran, from which an enriched beta glucan may be extracted; a refined oat flour, from which oat starch and oat protein may be extracted; and a pearled oat groat extract from which further products, such as an oat anti-irritant can be recovered.
