“…24 The wet viscous coacervate can be used as formed, or dried to remove the excess of water in order to obtain a dry glass. The majority of studies presented so far in the literature refer to the as-made polyphosphate coacervates, with reference to the processes behind their formation, 26,27 rheology, 22,28 structure, 20,23,24,[29][30][31] effect of thermal treatment, 32 degradation and haemostatic properties. 19 However, very little work has been presented on dried PBG prepared using the coacervate method and particularly on the relationship between the as-made coacervate and the final glass.…”

“…Sodium polyphosphate is an inorganic, polymeric, poly anionic electrolyte with high cation sequestration ability [ 40 ]. Initially, it was named sodium hexametaphosphate, and later, the nomenclature was modified because the widely used method for the production of this polymeric salt produces a mixture of linear polymers with different lengths.…”

Enzymes serve as biocatalysts for innumerable important reactions, however, their application has limitations, which can in many cases be overcome by using appropriate immobilization strategies. Here, a new support for immobilizing enzymes is proposed. This hybrid organic-inorganic support is composed of chitosan—a natural, nontoxic, biodegradable, and edible biopolymer—and sodium polyphosphate as the inorganic component. Lipase B from Candida antarctica (CALB) was immobilized on microspheres by encapsulation using these polymers. The characterization of the composites (by infrared spectroscopy, thermogravimetric analysis, and confocal Raman microscopy) confirmed the hybrid nature of the support, whose external part consisted of polyphosphate and core was composed of chitosan. The immobilized enzyme had the following advantages: possibility of enzyme reuse, easy biocatalyst recovery, increased resistance to variations in temperature (activity declined from 60 °C and the enzyme was inactivated at 80 °C), and increased catalytic activity in the transesterification reactions. The encapsulated enzymes were utilized as biocatalysts for transesterification reactions to produce the compound responsible for the aroma of jasmine.
