Abstract:
... Protein fractions were isolated from wheat flour including albumin, globulin, glutelin-1, glutelin-2 and prolamin. The free and bound phenolics were extracted from each protein fraction to determine the impact of their removal on allergenicity, antioxidant activity and the inhibitory activities of the angiotensin converting enzyme. The glutelin-1 fraction showed the highest protein content and yie ...

Abstract:
... Three genes encoding novel D-hordeins, Ns 1.3, Ns 2.6, and Ns 2.9 were isolated from Psathyrostachys juncea. The Ns 1.3 differed from Ns 2.6 and Ns 2.9 by having a shorter open reading frame (< 1.5 kb versus > 2.5 kb), and was probably not expressed as a normal protein, while the activities for Ns 2.6 and Ns 2.9 were verified by bacterial expression. Though highly similar primary structure to whea ...

Abstract:
... Celiac disease is triggered by the ingestion of gluten from wheat, barley, rye, and possibly oats. Gluten is quantitated by DNA-based methods or enzyme-linked immunosorbent assays (ELISAs). ELISAs mostly detect the prolamin fraction and potentially over- or underestimate gluten contents. Therefore, a new independent method is required to comprehensively detect gluten. A targeted liquid chromatogra ...
