European cereal-based fermented foods (ECBFFs) and alcoholic beverages have been fundamental components of regional diets for centuries, providing unique flavor profiles, essential nutrients, and a diverse array of health benefits. These foods, which encompass breads, beverages, and porridges, derive their functional and culinary properties from the activity of lactic acid bacteria and yeasts. This review examines the nutritional and functional characteristics of ECBFFs, with a focus on their microbial composition and fermentation processes. It highlights various ECBFFs and alcoholic beverages, including conventional and sourdough breads, tarhana, boza, kvass, and beers examining their health-promoting properties and potential for commercial expansion. Key findings from the literature show that certain ECBFFs are abundant in prebiotics and probiotics, primarily due to the fermentation processes involving lactic acid bacteria and yeasts. These microorganisms generate bioactive compounds such as organic acids, bacteriocins, and phenolic compounds, which exhibit antimicrobial, antioxidant, and anti-inflammatory activities. ECBFFs can also enhance digestibility, improve mineral bioavailability, and support gut health, thereby promoting overall well-being. From a commercial perspective, products like Yosa and Proviva demonstrate the feasibility of developing innovative ECBFFs that align with contemporary dietary preferences. The future of ECBFFs is promising, offering extensive opportunities for research, innovation, and large-scale commercialization to meet the increasing consumer demand for functional, plant-based foods.

β-conglycinin (β-CG) is a prominent storage protein belonging to the globulin family in soybean (Glycine max) seeds. Along with other soybean proteins, it serves as an important source of essential amino acids and high-quality nutrition. However, the digestibility and nutritional value of β-CG are key factors affecting the nutritional profile of soy-based foods. The heterotrimeric, secondary, and quaternary structures of β-CG, particularly the spatial arrangement of its α, α’, and β subunits, influence its functional properties. Considering these aspects, β-CG emerges as a significant protein with diverse applications in the food and health sectors. Therefore, this review explores β-CG's composition, structure, function, health implications, and industrial uses. Salient discussions are presented on its molecular structure, nutrition, digestibility, allergenicity, and techno-functions including emulsification, solubility, gelling, and structure–function complexities. Overall, the multifaceted potential of β-CG in the healthcare sector and the food industry is evident.

The global probiotics market has been continuously growing, driven by consumer demand for immune-enhancing functional foods, dietary supplements, and natural therapeutics for gastrointestinal and gut function-mediated diseases. Probiotic microorganisms represent a diverse group of strains with complex but generalized mechanistic patterns. This review describes the various immunomodulatory mechanisms by which probiotics exert their effects, including the competitive exclusion of pathogenic microbes, production of antimicrobial substances, modulation of the immune system, and improvement of gut barrier function. In addition, the various formulations and methods of delivery of probiotics and the safety concerns associated with these products are also discussed.

Oceans cover over 70% of the Earth's surface and provide home to structurally diverse marine organisms. These creatures contribute to more than half of the biodiversity of the world and produce several bioactive molecules, including peptides. In the past years, scientific research has been focused on the compositions, sequences and structural features of marine-derived peptides. Based on their amino acid sequences, they have demonstrated a wide range of biological functions, including antithrombotic, antihypertensive, anticancer, antioxidant, antimicrobial, antiageing, anti-inflammatory, immunomodulatory and other multifunctional activities that are based on their structure, hydrophobicity, binding affinity, charge and other factors. This review focuses on novel techniques used to produce marine peptides and explores the structure–function relationships of these peptides derived from representative phyla, namely Cnidaria, Annelida, Mollusca, Arthropoda, Chordata, Echinodermata and Porifera. Furthermore, notable considerations regarding the structure–function basis of marine peptide applications are discussed.
