Biopolymer-Biopolymer Interactions at Interfaces A majority ofprocessed foods are either foam-type (air-in-water) orernulsion-type (oil-in-water) products. The interactions can be simple covalent cross-links or more complex junction zone or particulate-type interactions. A number of biopolymer systems can self-assemble to form networks and gels and the assembly can occur by a variety of mechanisms. Juan M Ruso.

The properties of biopolymer particles and their impact on the physicochemical and functional properties of foods are described. The molecular characteristics and interactions of the building blocks (proteins and polysaccharides) used to assemble these particles are briefly reviewed. Biopolymer interactions affect the functional properties of edible films based on agar, cassava starch and arabinoxylan blends. Biopolymer particulates can be fabricated using many different physicochemical approaches, for example, extrusion/gelation, segregation, aggregation, size‐reduction, and solvent removal. All of these approaches demand a firm knowledge of the properties of food biopolymers, their possible interactions in solution, and structural assembly principles. To establish the relationship between biopolymer interactions, water dynamics, and crumb texture evolution in time, proton mobilities in starch and gluten model systems and bread were investigated with NMR relaxometry.

Biopolymer-Based Formulations: Biomedical and Food Applications presents the latest advances in the synthesis and characterization of advanced biopolymeric formulations and their state-of-the-art applications across biomedicine and food science. Food Hydrocolloids. Among mixed biopolymer systems that segregate, decreased temperatures can be utilized to favor separation, which in turn increases biopolymer interaction within the dispersed phase (Loren and others 2001). Natural biopolymers, including proteins, polysaccharides, lipids, and biopolyesters, have a key role in improving food quality, being used as alternative food packaging materials, structuring elements, rheology modifiers, and edible coatings or even structured into micro- and nanoparticulate systems for encapsulation, protection, and controlled release of active and bioactive molecules. It shows that biopolymer research is not limited to products made of biopolymers, but that these polymers could play a vital role in other areas of research too. I.
