    Opis:
    The presence of gluten is considered fundamental for successful breadmaking. However, the ingestion of gluten by susceptible individuals has been associated with the development of gluten-related disorders such as celiac disease, wheat allergy, and non-celiac gluten sensitivity. The elimination of gluten from cereal-based baked products has a detrimental effect on the breadmaking process and sensory properties, and raises technological challenges in terms of making good quality leavened bread. The use of non-gluten raw materials changes the rheological behaviour of the gluten-free dough, which may result in different processing performance and associated post-baking quality of the obtained bread. Gluten-free bread tends to have a poor visual texture characteristics, a low nutritional value, reduced mouthfeel and flavour, as well as a shorter shelf-life. The aim of this review is to present the main problems related to gluten-free breadmaking technology and to summarise recent findings in the improvement of the technological, nutritional, and sensory properties of gluten-free bread. A great deal of this review focuses on the development of novel and healthy gluten-free breads formulated with flours, starches, hydrocolloids, and alternative nutrient-dense raw materials, which should fulfil all quality requirements for bakery products as well as meet the needs of celiac consumers.

    Opis:
    This work aimed to examine the rheological properties and structural features of newly developed gluten-free doughs with maize (M), field bean (FB), maize-filed bean (MFB), and maize-field bean improved with hydrothermally-treated maize (IMFB), and compare them with soft wheat (SW) dough as a control. The relationships between viscoelastic characteristics, pasting properties of dough, and structure of non-gluten proteins analyzed using FT-Raman spectroscopy were investigated. All gluten-free doughs showed significantly higher values of the elastic modulus than SW dough. The low values of tan δ for doughs of M, MFB, and IMFB formulas indicated strong contribution of the solid character in their structural formation as compared to SW and FB doughs. Protein backbone of maize and maize-based doughs was characterized by the absence of pseudo-β-sheet structure and a high content of β-sheet accompanied with a low content of antiparallel-β-sheet. According to principal component analysis (PCA), a strong relationship was found between protein secondary structure, tan δ, gelatinization temperature, and between aromatic amino-acid chains, peak viscosity, and breakdown. The mechanism of non-gluten protein network establishment was based on the formation of β-sheet and α-helix structure. The study results indicate the significant involvement of trans-gauche-gauche (TGG) and trans-gauche-trans (TGT) disulfide bridges in the formation of the non-gluten protein matrix rather that gauche-gauche-gauche (GGG) conformation. PCA analysis showed that the water absorption of the starch granules increased with the greater exposition of the tyrosyl residues.

    Opis:
    This study aimed to formulate flour blends from modified cassava flour (MCF) and suweg flour (SF) and use them to produce gluten-free steamed brownies (GFSB) with desirable qualities. The blends varied in the proportions of MCF and SF by weight, namely 80:20 (F1), 70:30 (F2), and 60:40 (F3). Wheat flour-based steamed brownies (WFSB) served as the control. The results showed that the MCF to SF ratio significantly influenced various parameters of flour blends, such as chemical compositions, color characteristics, pasting, and functional properties. Higher SF content in the blend decreased peak viscosity, breakdown, and setback. Water absorption capacity also decreased as the MCF to SF ratio in the flour blend increased. The color of flour blends with an increasing proportion of SF was getting darker and more different from the color of wheat flour. GFSB exhibited lower volume expansion than WFSB. Increasing SF content in the flour blend increased the texture parameters of GFSB including hardness, cohesiveness, gumminess, and chewiness Values of color difference, representing color variation between gluten-free and control brownies, ranged from 2.30 to 6.32, where the GFSB-F1 was more similar in color to WFSB. Preference levels for color, aroma, and texture of GFSB did not significantly differ from WFSB. However, GFSB-F2 was preferred in taste and overall acceptance over WFSB. The utilization of modified cassava flour and suweg flour blends in gluten-free steamed brownies offers a promising avenue for diversifying gluten-free baking options.
