However, if the high amount of protein is the fraction of interest for food application, the other fractions (fibres, vitamin, minerals) comprised in BSG could be of interest, [46] rendering the extraction potentially obsolete. Other possible applications for this protein fraction or hydrolysate lies in the cosmetic sector where such compounds from wheat and oat are already used for their moisturizing and nutritive properties. Protein extract could also be used for edible film production out of prolamin, or for composite materials using BSG's hordein.
