СВЕРХКРИТИЧЕСКАЯ ФЛЮИДНАЯ ЭКСТРАКЦИЯ ХЛОРОФИЛЛОВ И КАРОТИНОИДОВ LAMINARIA DIGITATA

Integrated bioethanol and protein production from brown seaweed Laminaria digitata.

A wild-growing glucose-rich (i.e. 56.7% glucose content) brown seaweed species Laminaria digitata, collected from the North Coast of Denmark in August 2012, was used as the feedstock for an integrated bioethanol and protein production. Glutamic acid and aspartic acid are the two most abundant amino acids in the algal protein, both with proportional content of 10% in crude protein. Only minor pr...

Kinetics modeling of alginate alkaline extraction from Laminaria digitata.

Alginates being depolymerized during their alkaline extraction, reducing extraction time could help producing higher rheological quality alginates. The purpose of the present work is to study fresh Laminaria digitata destructuration during alkaline extraction and its link to extraction kinetics. Both alginate extraction yield and mean diameter of algae particles were followed for different valu...

A New Process for Extracting Alginates from Laminaria digitata : Reactive Extrusion

Alginates are natural polysaccharides that are extracted from brown seaweeds and widely used for their rheological properties. The main step in the extraction protocol used in the alginate industry is that of alkaline extraction. A batch process is used for this step, which is time-, water-, and reactantconsuming. The possibility of extracting by reactive extrusion was investigated. The reactiv...
