Abstract

Brown algae are a valuable source of various biopolymers, with alginate standing out as a phycocolloid of great industrial importance. Although the extraction process is well established on an industrial scale, several innovative and environmentally friendly extraction technologies have been explored to improve the efficiency of the process both in terms of yields and energy and solvent consumption. The review aims to describe and analyze different strategies used to extract alginate from brown algae, including different pre-treatment methods used before extraction. In addition, the impact of these extraction technologies, with or without pre-treatments, on alginate's structural and techno-functional…
