Production of Protein Isolate from Quinoa and Studying of Its Some Physiochemical Properties

Determining the protein isolate’s (PI) chemical makeup, amino acid profile, FTIR, and functional characteristics was the aim of this investigation. Protein, fat, fiber, ash, carbs, and moisture are all present in large amounts in QPI (94.25, 2.43, 0.0, 1.83, 1.56, and 5.92%, respectively). In this work, we used the techniques of alkaline solubilization and acid precipitation to extract proteins from white quinoa with the goal of understanding how the extraction pH (11) affected the quinoa protein isolate’s (QPI) recoverability, purity, and rate of recovery. According to the results, protein purity was 81%, protein extractability was 56.45%, and recovery was 86%. At pH 7 and 11. At PH 7, the maximum solubility for suspension was 67%.
