Technical Abstract: It has been demonstrated that zein fibers can be produced using the electrospinning technique. Fibers electrospun from acetic acid solution under suitable conditions provide fibers with a more consistent morphology (round 0.5-2.0 micro fibers) compared to fibers produced from aqueous ethanol solutions. Spinning continuity of zein acetic acid solutions is significantly improved as well. Commercial zein is produced via extraction of corn gluten meal using aqueous alcohol solvents. In order to better model a possible commercial process, acetic acid was used to extract zein from corn gluten meal. It was found that acetic acid removes more protein than the more traditional solvent systems. The impact of time, temperature and other solvents on extractability will be presented. The zein acetic acid solution obtained from corn gluten meal was successfully electrospun producing fibers of similar quality to that produced from commercial zein.
