Autoria: BATISTA, A. M. G.; ASCHERI, D. P. R.; TEIXEIRA, I. R.; SIGNINI, R.; MOTA, R. D. P.; ASCHERI, J. L. R. Conteúdo: This study aimed to characterize corn (CS), wolf fruit (WF), and butterfly lily (BL) starches; to develop bioactive coatings from pure starches and their binary and ternary blends; and to evaluate the synergistic effects of these formulations on the physiological quality of common bean seeds. Films were prepared by thermocompression (80 °C, 6 min, 3 t) of film-forming solutions obtained via microwave processing and formulated using a simplex-centroid mixture design. The starches were characterized in terms of amylose content, Scanning Electron Microscopy, Fourier Transform Infrared Spectroscopy, Differential Scanning Calorimetry, Rapid Visco Analyser, while the films were evaluated for thickness, water solubility, and water vapor permeability. The film-forming solutions were applied as coatings, and seed physiological quality was assessed through germination, first count, seedling length, and dry mass. BL exhibited higher gelatinization temperatures and produced films with adequate thickness and moderate permeability, indicating greater structural stability. The CS:BL blend produced films with balanced hydration, promoting rapid and uniform water uptake. Coatings based on BL and CS:BL showed the highest germination percentages, whereas CS:WF resulted in lower physiological performance. These results demonstrate that film properties directly influence seed vigor and germination. BL, alone or blended with CS, represents a promising starch-based material for seed coating, promoting high physiological quality and environmentally friendly characteristics.

Autoria: OLIVEIRA, M. E. A. S.; CARVALHO, H. J. M.; MARTINEZ-VILLALUENGA, C.; TAKEITI, C. Y.; CLERICI, M. T. P. S. Conteúdo: Buckwheat (Fagopyrum spp.), mainly represented by common buckwheat (Fagopyrum esculentum) and Tartary buckwheat (Fagopyrum tataricum), is a climate-resilient pseudocereal with high nutritional value. Its unique composition, rich in proteins, slowly digestible starches, and phenolic compounds, links sustainability with health-promoting properties. The aim of this review was to reinforce and summarize current knowledge on buckwheat as a source of bioactive compounds, the molecular mechanisms underlying starch interactions, technological processing, and its application in gluten-free products. Evidence indicates that buckwheat proteins and phenolic compounds interact with starch, modulating its digestibility and contributing to improved glycemic control. Advances in food technology, particularly through 3D printing and steam explosion treatments, offer opportunities to design gluten-free foods with a low glycemic index (GI) and desirable sensory attributes. These developments position buckwheat as a promising ingredient for celiac and nonceliac consumers, as well as for individuals managing glucose metabolism or using GLP1 analog medications.

Autoria: SILVA, B. A.; VARGAS-SOLÓRZANO, J. W.; STEPHAN, M. P.; DELIZA, R.; MARTINS, I. B. A.; CARVALHO, C. W. P. de; ASCHERI, J. L. R. Conteúdo: Background: Starch-based breads can closely mimic wheat bread in texture and appearance; however, their nutritional value must be improved while maintaining their inherent bread-like characteristics. The objective of this study was to incorporate whole-grain pearl millet flour (PMF) into a starch-based bread formulation to enhance its dietary fiber and protein content. (2) Methods: The PMF was obtained using a combination of laboratory rollers and hammer mills, as well as appropriate sieves to obtain a particle size ≤ 250 µm. The incorporation of PMF affected the properties of the base flour (BF), dough, and gluten-free bread (GFB). (3) Results: In the BF, setback viscosity was significantly reduced from 6379 to 1354 mPa·s. Similarly, in the freshly kneaded dough, both the elastic and viscous moduli decreased, from 168.3 to 17.8 kPa and from 36.3 to 4.3 kPa, respectively. During fermentation, dough-specific volume increased from 0.76 to 1.73 cm3/g. In the GFB, the moisture content decreased from 47.9 to 42.2%, bread specific volume varied from 2.13 to 2.68 cm3/g, and crumb hardness increased from 12.8 to 25.3 N. PMF incorporation segmented bread consumers into two preference-based clusters, characterized by lower (1) and higher (2) PMF levels. (4) Conclusions: Incorporating 30% PMF increased the fiber and protein contents of the starch-based bread by 4.9% and 2.2%, respectively, without compromising specific volume (2.56 g/cm3) or overall acceptance, which remained comparable to that of a commercial gluten-free bread (7.30 and 6.32 for clusters (1) and (2), respectively).

Z.; SILVA, P. de S.; ASCHERI, J. L. R. Conteúdo: The development of gluten-free products entails substantial technological and formulation challenges, primarily due to the difficulty of reproducing the structural, sensory, and nutritional attributes of gluten-containing analogues. The absence of gluten—responsible for the viscoelastic network that confers extensibility, gas retention, and structural integrity to wheat-based doughs—represents a major limitation in processing and product quality. To compensate for this deficiency, gluten-free formulations commonly incorporate optimized combinations of starches, hydrocolloids, and plant proteins to establish an alternative network. Starch gelatinization and the formation of a cohesive, viscous matrix by gums such as xanthan and guar contribute to dough integrity and rheological performance. Concurrently, the interactions between vegetable proteins and these polysaccharide components promote gas retention and stabilize the internal structure during fermentation and baking. This composite system partially replicates the viscoelastic behavior of gluten, thereby improving the texture, stability, and overall quality of gluten-free products.
