“…They are naturally synthesized by plants (e.g., starch and cellulose), animals (e.g., chitosan and chitin), and microorganisms (e.g., dextran and gellan gum) to produce energy and fulfill physiological and structural functions [ 16 ]. Some polysaccharides can also be enzymatically and chemically synthesized (e.g., condensation), such as certain cyclodextrins and chitosan derivates, to create non-natural, well-defined, and pure structures [ 17 ]. In commercial applications, polysaccharides are widely used as emulsifiers, gelling agents, flavorings, and encapsulants [ 18 ] as a result of their physicochemical properties such as viscosity and solubility [ 16 ].…”

Spray-drying is a continuous encapsulation method that effectively preserves, stabilizes, and retards the degradation of bioactive compounds by encapsulating them within a wall material. The resulting capsules exhibit diverse characteristics influenced by factors such as operating conditions (e.g., air temperature and feed rate) and the interactions between the bioactive compounds and the wall material. This review aims to compile recent research (within the past 5 years) on spray-drying for bioactive compound encapsulation, emphasizing the significance of wall materials in spray-drying and their impact on encapsulation yield, efficiency, and capsule morphology.

“…Recently, there has been a growing interest in polysaccharide-mimetics, often referred to as “pseudo-polysaccharides”, which feature monosaccharide repeating units and non-native linkages (e.g., amide, carbonate, etc. ). − These alternatives are gaining popularity over native polysaccharides because of their facile and controlled synthesis and their ability to approach and even surpass the functions of native polysaccharides in material and biomedical applications. , In their seminal work, Endo et al reported the anionic ROP of five-membered glucopyranose carbonates, affording glucose-derived polycarbonates with moderate control . Further advancing the polymerization of glucopyranose carbonates, Wooley et al reported the organocatalytic living anionic ROP of six-membered bicyclic glucopyranose carbonates .…”

Recent advances in synthetic methods and monomer design have given access to precision carbohydrate polymers that extend beyond native polysaccharides. In this article, we present the synthesis of a class of chemically recyclable ester-linked pseudopolysaccharides via the living anionic ring-opening polymerization of glucurono-1,6-lactones. Notably, the pseudo-polysaccharides exhibited defined chain-end groups, well-controlled molecular weights, and narrow molecular weight distributions, all hallmarks of living polymerization. Furthermore, we demonstrate that our approach is modular, as evidenced by tunable glass transition temperatures (T g ) and the ability to produce both amorphous and semicrystalline polymers by adjusting the monomer side chain structure. Lastly, we showcased the complete catalytic chemical recycling of these pseudo-polysaccharides back to the monomers. The flexibility of the polymerization and the recyclability of these pseudopolysaccharides promote a sustainable circular economy while offering the potential to access polysaccharide-like materials with tunable thermal and mechanical properties.
