Impact of drying on the sodium alginate obtained after polyphenols ultrasound-assisted extraction from Ascophyllum nodosum seaweeds

Leticia Montes et al.

Summary: Ultrasound-assisted extraction of polyphenols from brown seaweeds can leave a solid phase where alginates can be extracted. This study characterized alginates extracted with and without intermediate drying stages at different temperatures, producing two bioactive compounds. High temperature drying decreased the average block length and viscosity of the alginate.

The Properties of Sodium Alginate Hydrocolloids upon Sorption Binding of Papain

S. A. Koksharov et al.

Summary: This study investigated the adsorption immobilization of papain in strongly and weakly acidic colloidal solutions of sodium alginate under low-speed stirring to determine the conditions for obtaining biopolymer coatings. The state of the dispersed phase was characterized using scanning electron microscopy and dynamic light scattering. The Langmuir model was used to describe the sorption equilibrium and determine the thermodynamic characteristics of interactions and a probable enzyme sorption mechanism in the polymer structure, which aligned with the results of IR spectra analysis.
