Special Issue Information

Dear Colleagues,

Food polysaccharides, including starch and other non-starchy polysaccharides, have long been important throughout the history of the human diet. As the food industry has been gaining increasing impetus recently to create desired nutritional profiles and to improve the sensory perception of food products, we expect the continued increase in importance in understanding the physicochemical characteristics of food polysaccharides, such as their hydration process and solubility, associative structures in solution, gelation properties, interfacial behaviors, and interactions with other food components. A typical example is that polysaccharide food gels have recently been appreciated as a good candidate for developing health-care foods for the elderly with dysphagia. Due to the great complexity in chemical structures, however, it is very challenging to describe the physicochemical properties of a broad range of food polysaccharides by generalizing a universal theoretical framework. Therefore, expanding the detailed knowledge on food polysaccharides regarding their basic physicochemical properties and new food applications by experimental investigation is still necessary and in urgent need. Fortunately, significant progress has been made in the past few decades. In this Special Issue, we wish to make a collection of papers that focus on the physicochemical characteristics of food polysaccharides, starches, and gels to offer a communication platform to interested readers.

Rice starch, as one of the most abundant and renewable polysaccharide resources in nature, holds great potential for applications in the food, pharmaceutical, and industrial fields due to its wide availability, low cost, and biodegradability. However, its inherent limitations—such as susceptibility to retrogradation and poor emulsifying capacity—have hindered its development into high-value-added products. Emulsion technology presents a promising strategy to overcome these challenges by constructing stable oil–water interfacial systems using various stabilizers. This review highlights recent advances in the functional modification of rice starch through emulsion-based techniques, with a particular focus on four key approaches: polysaccharide–protein complexation, chemical and physical modifications, Pickering emulsions, and microcapsule formation. These strategies significantly improve the emulsifying ability of rice starch, inhibit retrogradation, and expand its potential applications in sustained drug delivery, functional foods, and intelligent packaging. Overall, interfacial engineering of rice starch offers an innovative and effective pathway for its high-value utilization, demonstrating substantial promise for future industrial applications.

Casein is among the most abundant proteins in milk and has high nutritional value. Casein’s interactions with polysaccharides, polyphenols, and metal ions are important for regulating the functional properties and textural quality of dairy foods. To improve the functional properties of casein-based foods, a deep understanding of the interaction mechanisms and the influencing factors between casein and other food components is required. This review started by elucidating the interaction mechanism of casein with polysaccharides, polyphenols, and metal ions. Thermodynamic incompatibility and attraction are the fundamental factors in determining the interaction types between casein and polysaccharides, which leads to different phase behaviors and microstructural types in casein-based foods. Additionally, the interaction of casein with polyphenols primarily occurs through non-covalent (hydrogen bonding, hydrophobic interactions, van der Waals forces, and ionic bonding) or covalent interaction (primarily based on the oxidation of proteins or polyphenols by enzymatic or non-enzymatic (alkaline or free radical grafting) approaches). Moreover, the selectivity of casein to specific metal ions is also introduced. Factors affecting the binding of casein to the above three components, such as temperature, pH, the mixing ratio, and the fine structure of these components, are also summarized to provide a good foundation for casein-based food applications.
