• Wheat bran (WB), a low-cost industrial by-product, is a vital source of high-quality proteins, minerals, vitamins, and several bioactive compounds. The present study encompasses the identification of appropriate bran streams of a commercial roller flour mill (CRFM) essentially based on hector liter weight, (HLW), optimization of WB protein isolation process, amino acid characterization, rendering more emphasis on simple water-soluble albumins, having higher commercial viability, and its application in food formulation. Total WB protein was 16.18% protein, the sum of the extracted proteins viz. albumin (2.43%), a prolamin (2.47%), glutelin (5.25%), globulin (1.92%), and insoluble proteins (4.09%) was 12.08%. Following albumin extraction, residual WB was subjected to ultra-sonication which further increased albumin protein yield from 2.43 to 3.07%. The extracted WB albumin isolate (WBAI) was utilized to develop high protein bread having significantly high volume and protein content, compared to control bread. The structural and sensorial attributes of the developed bread were superior compared to control bread. Thus, WBAI has a tremendous scope as a natural, affordable potential inexpensive food improver/fortificant to address protein-energy malnutrition (PEM). The process has the great advantage of being eco-friendly, besides, residual bran can still be used as cattle feed, enhancing profitability and viability.
