Special Issue Information

Dear Colleagues,

This Special Issue explores the nutritional and functional aspects of food components, such as proteins/peptides, polyphenols, microbial strains, polysaccharides, and fats. We welcome submissions on the following topics:

New Sources: The discovery of novel food components with unique nutritional or health benefits from plant, animal, or microbial sources.

Advanced Technologies: The application of artificial intelligence (AI) and physical processing techniques to enhance the extraction, modification, and utilization of bioactive substances.

Mechanisms: Studies on the absorption, metabolism, and biological effects of food components at molecular, cellular, and physiological levels.

Biotechnology and Gut Health: Research on bioactive substances' probiotic efficacy and immunometabolic regulation of the gut microbiota.

Genotypic Diversity and Genome-Wide Association Study of Protein Content and Amino Acid Profile in Diverse Potato Accessions

The genotypic diversity and genome-wide association study (GWAS) of potato proteins and amino acid content were investigated in two environments: 98 potato accessions in Environment I and 93 in Environment II. Results revealed that aspartic acid was the most abundant amino acid in environment I and glutamic acid in environment II. The limiting amino acids were cysteine in both environments. The environmental variance accounted for more than 40% of the total variance for all traits except for serine and gamma amino butyric acid (GABA), indicating that potato protein and most amino acids were affected by growing seasons. GWAS identified 78 significant loci associated with potato protein and amino acid contents. The pleiotropic loci, especially those located on chromosomes 6, 9, and 11, provide a strong genetic basis for quality improvement. This study provides genetic insights into potato proteins and amino acid diversity, thereby enhancing molecular breeding for nutritional qualities. Full article

This study systematically investigated the drying kinetics and quality characteristics of Houttuynia cordata Thunb. (HCT) under different processing conditions, evaluating how freeze-drying and hot-air drying (40 °C, 50 °C, 60 °C) affect bioactive compound preservation, antioxidant efficacy, and metabolic profiles to identify the optimal drying method for maximizing its functional benefits. A thin-layer drying model was established to evaluate drying parameters such as effective diffusion coefficient and activation energy. Changes in chemical composition, sensory properties, and antioxidant activity were analyzed using UHPLC-LTQ-Orbitrap-MS, electronic nose/tongue, and HepG2 cell assays. Results showed that the Aghabashlo model was optimal for demonstrating the drying process with the best fit. The 50 °C heating temperature was shown to yield the highest diffusion coefficient. Hot-air drying at 50 °C balanced efficiency and sensory quality, whereas 60 °C significantly altered flavor and metabolite composition. Results of the metabolomic analysis indicated that freeze-drying enhanced the retention of phenolic acids and flavonoids, while hot-air drying led to increased fatty acid metabolites. Freeze-drying preserved the antioxidant activity and natural flavor of HCT. Nevertheless, the metabolic fate of rutin, quercetin, and chlorogenic acid was not significantly affected by the drying method (freeze-drying vs. 50 °C drying). These findings provide a theoretical foundation for improving HCT’s therapeutic and sensory qualities through optimized drying techniques. Full article

Plant powders have exhibited great potential to enhance the antioxidant activity of yogurt. This study aims to evaluate the effects of hawthorn powder (1.0–3.0%, w/w) addition on the antioxidant activity and physical properties of set-type yogurt. The results demonstrated that yogurt containing 1–2% hawthorn powder exhibited improvements in quality, water-holding capacity, and texture. Notably, the antioxidant activities, including the DPPH radical, hydroxyl radical scavenging rate, and Fe2+ chelating activity, reached 68.2 ± 4.9%, 81.6 ± 0.5%, and 72.2 ± 2.0%, respectively, and were higher than those of ordinary yogurt. Microstructural observation revealed that appropriate hawthorn powder concentration promoted homogeneous protein network formation, contributing to improved texture stability. In conclusion, this research is of interest to the development of functional dairy products. Full article
