Special Issue Information

Dear Colleagues,

Many natural biopolymers are derived from muscle foods, and structure variations of these gellants may have a significant impact on creating molecular structures of gels with predictable functionality. The investigation of the gelation mechanism and the improvement in the gelation characteristics of animal-sourced proteins during processing and storage have represented hot research topics in the muscle food industry in recent years. At the same time, the creation and application of novel gel-based materials have brought new benefits to the food industry, especially in terms of preservation.

We have organized this Special Issue on “Food Gels: Gelling Process and New Applications” to summarize recent developments in the formation mechanism of food gels, the improvement in gelation properties, and the functionalization and potential applications of novel food gels, among many other relevant issues. We are looking forward to receiving fresh data and reviews on food gels from both experimental and theoretical perspectives.

The aim of this study was to investigate the hypoglycemic activity and mechanism of G. lemaneiformis polysaccharide gels (GLP and GLP-HV) based on IR/IRS-2/PI3k/Akt/Glut4 and glycometabolism signaling pathways in HepG2 cells. After H2O2-Vc degradation, the molecular weight of G. lemaneiformis polysaccharide gel declined from 1478 kDa to 16 kDa. Molecular weight chromatogram and distribution indicated that GLP-HV had a high molecular weight homogeneity compared to GLP. G. lemaneiformis polysaccharide gels significantly decreased the TC, TG, LDL-C, MDA, and LDH contents and enhanced the activities of HDL-C, T-AOC, CAT, GSH-PX, SOD, insulin, and glycogen in HepG2 cells. Fluorescent staining results showed that G. lemaneiformis polysaccharide gels reduced ROS and calcium ions levels in HepG2 cells. GLP and GLP-HV displayed excellent hypoglycemic activity, with GLP-HV performing better. Furthermore, qPCR and Western blot analysis revealed that G. lemaneiformis polysaccharide gels remarkably strengthened the levels of IR, IRS-2, PI3K, Akt, Glut4, HK, G6PD, PFK, PEPCK, GK, PK genes, and proteins. Spearman’s correlation analysis revealed that the IR/IRS-2/PI3k/Akt/Glut4 signaling pathway played a dominant role in regulating activity. These results show that G. lemaneiformis polysaccharide gels present a prominent hypoglycemic effect mediated by the IR/IRS-2/PI3k/Akt/Glut4 and glycometabolism signaling pathways, with the former playing a dominant role.

The growing demand for plant-based foods, together with environmental and ethical concerns associated with animal-derived ingredients, has intensified research into alternative gelling agents for the food industry. Within this framework, the review focuses on the use of vegetable hydrocolloids in dairy analogues, confectionery-type gels, and emerging 3D-printed food systems. Plant-based hydrocolloids have emerged as promising candidates to replace animal gelatin across diverse applications. This review highlights recent advances in the use of plant-based hydrocolloids, focusing on κ-carrageenan (κ-C) and its blends with other plant-based gums as functional gelling systems for food products. Particular attention is given to synergistic combinations of κ-C with other hydrocolloids (e.g., locust bean gum, konjac glucomannan, and starches) as strategies to modulate gel strength, stability, and sensory properties. The mechanical and sensory performance of these systems is critically examined. Key advantages of plant hydrocolloids are discussed, such as their versatility, compatibility with a range of ingredients, and gelation under varied conditions, along with their limitations, including difficulties in replicating gelatin’s sensory profile, formulation challenges, and sensitivity to processing parameters. Finally, the review identifies future research directions and formulation strategies aimed at developing innovative plant-based gels that meet both the technological and sensory expectations of manufacturers and consumers in the food sector.
