Special Issue Information

Dear Colleagues,

Gels play a critical role in the food industry. They are widely used in various food categories, such as jelly, pudding, soft candy, and canned food. In order to utilize them more efficiently, economically, and scientifically, it is necessary to have a deeper understanding of this topic. Gums can stabilize, emulsify, and suspend particles in food so that they thicken or form gels, giving a suitable flavor to the product. Gel properties also have an important impact on food quality. In order to enhance product quality and effectively fulfill clients’ needs, it is vital to comprehend the formation process of food gels. In recent years, researchers have conducted in-depth research on gelation mechanisms and effects of common gums such as gelatin, carrageenan, sodium alginate, xanthan gum, etc.

In order to provide specific guidance for the application of food gels in food production and processing, there are also new challenges, namely:

The emergence of novel animal, vegetable, algae, microbial gums, chemically modified, or composite gels; the exploration of the physicochemical properties, gelation, and interaction mechanism; brittle gelling, which causes the food product to be seriously dehydrated.

Thus, we invite researchers to contribute their current forays into this important emergent field in this Special Issue of Gels.

A novel β-D-fructofuranosidase gene was identified via database mining from Leptothrix cholodnii. The gene was chemically synthesized and expressed in Escherichia coli, resulting in the production of a highly efficient enzyme known as LcFFase1s. The enzyme exhibited optimal activity at pH 6.5 and a temperature of 50 °C while maintaining stability at pH 5.5–8.0 and a temperature below 50 °C. Furthermore, LcFFase1s exhibited remarkable resistance to commercial proteases and various metal ions that could interfere with its activity. This study also revealed a new hydrolysis function of LcFFase1s, which could completely hydrolyze 2% raffinose and stachyose within 8 h and 24 h, respectively, effectively reducing the flatulence factor in legumes. This discovery expands the potential applications of LcFFase1s. Additionally, the incorporation of LcFFase1s significantly reduced the particle size of coagulated fermented-soymilk gel, resulting in a smoother texture while maintaining the gel hardness and viscosity formed during fermentation. This represents the first report of β-D-fructofuranosidase enhancing coagulated fermented-soymilk gel properties, highlighting promising possibilities for future applications of LcFFase1s. Overall, the exceptional enzymatic properties and unique functions of LcFFase1s render it a valuable tool for numerous applications. Full article

Composite gels prepared with ovalbumin (OVA) as basic materials have been gradually utilized in food and biological fields. However, the structure and function of gels made from natural materials are not perfect, especially the hardness, viscoelasticity and water-holding capacity of gels, which are easily affected by various factors (pH, NaCl, etc.). In order to improve the antibacterial effect and safety of gels, and on the basis of exploring the bacteriostatic formula of lysozyme-oregano essential oil (LZ-OEO), the influence of microwave treatment on the stability of the composite bacteriostatic material gel was emphatically investigated and discussed so as to develop a new bacteriostatic gel material. The results revealed that the LZ-OEO antibacterial gel prepared by adding 20% OEO, with a ratio of 3:2 between OVA and LZ, was more stable after microwave treatment, and the synergistic antibacterial effect was significantly improved. That is, the OVA and LZ-OEO composite gel processed using a 350 W microwave treatment for 1 min had the highest hardness, the water-holding capacity reached 78.05% and a dense and ordered network structure was formed. In addition, the compound gel displayed excellent antibacterial effects against Staphylococcus aureus and Escherichia coli. The experimental findings in this study effectively expands the application scope of lysozyme antibacterial materials and provides a more favorable technical foundation for future development and utilization.
