Oat bran extract functions as a negatively charged ionic emulsifier that is effective over a wide pH and temperature range. Some of the stabilization techniques are used, like solvent extraction, steaming and sub-critical fluid extraction(defatting), in the production of fortified food like oat fortified noodles.
