The size distribution assessment of unreduced wheat gluten proteins of commercial Indian wheat varieties was examined using Size-Exclusion Fast Protein Liquid Chromatography. Elution profiles were fractionated into five peaks, with the molecular weights of eluting peaks as 130-30, 55-20, 28-10 and <10 kDa (IV and V), respectively. Peak I (glutenins) and II (gliadins) exhibited contrary results with AWRC (r = 0.928** and r = -0.831**), R/E ratio (r = 0.745** and r = -0.869**), gluten index (r = 0.959** and r = -0.994**), gliadin/glutenin ratio (r = -0.952** and r = 0.948**), dough development time (r = 0.830** and r = -0.930**), dough stability (r = 0.901** and r = -0.979**) and dough weakening (r = -0.969** and r = 0.986**). Significant statistical correlation was also observed for peak I and II with cookie hardness (r = 0.948** and r = -0.924**) and cookie spread (r = -0.837** and r = -0.743**) respectively. Peak III, IV and V occupied a minor fraction of whole and did not exhibit a statistically significant correlation with any of the quality parameters.

Plant-derived biostimulants have gained attention in agricultural practices for their potential to enhance crop quality and resilience. In this study, we investigated the effects of applying a maize gluten-derived protein hydrolysate at the soil level in vineyards on berry quality in a table grape variety, the Black Magic early table grapevine, during veraison. Our results demonstrate significant improvements in various parameters 14 days after application, including increased anthocyanin levels, enhanced sugar accumulation, and larger berry diameter while maintaining berry firmness.

Amaranth is an ancient crop of the family Amaranthaceae, but it is fairly new to Russia. Its seeds and leaf biomass contain a high-quality gluten-free protein, fatty acids, squalene (a polyunsaturated hydrocarbon), flavonoids, vitamins, and minerals. A comprehensive study of amaranth, enhancement of its breeding, and development of new cultivars will contribute to food quality improvement through the use of plant raw materials enriched for wholesome and highly nutritious components.

The application of flour is determined by the composition of its starch and storage proteins. Previously isolated diploid wheat is known to be amylose-free and possesses the same amylopectin structure as the wild-type. To reveal its characteristics, starch, protein, lipid, fiber, gluten, and allergen contents and rheological properties were analyzed and compared to its parental wild-type diploid wheat and commercially available hexaploid wheats.

In recent years, food allergies and food sensitivities have remained critical public health problems that affect approximately 15% of the global population. Wheat is a major food source worldwide, but it is also a common food allergen. Celiac disease is chronic immune-mediated enteropathy triggered by exposure to dietary gluten in genetically predisposed individuals; it can be treated only through strict gluten avoidance.

This study provides a comprehensive proteomic and metabolomic analysis of novel anthocyanin- and carotenoid-rich wheat varieties to assess their immunogenicity in the context of Celiac Disease. Using (semi)-quantitative mass spectrometry, the research found that gliadin expression and peptide release, particularly those containing immunostimulatory γ-gliadin epitopes, vary significantly across different wheat varieties. While non-targeted mass spectrometry provided valuable insights, the study acknowledged potential methodological biases, such limitations of ion current intensity as a measure of peptide abundance.
