Abstract

Abstract Herein, deep eutectic solvent combined with subcritical water extraction of seaweed polysaccharides were investigated from Saccharina japonica. In this regard, a deep eutectic solvent was added with sufficient amount of water and it was used as an extraction medium. To optimize, a Box–Behnken design was used to study the influences of the temperature (100 °C–150 °C), pressure (10–50 bar), water content (50%–70%), and liquid/solid (L/S) ratio (30–50 mL/g). The optimal conditions were 150 °C, 19.85 bar, and 70% water content, and L/S ratio of 36.81 mL/g showed a high yield of alginate (28.12%) and fucoidan (14.93%). FTIR, TGA, and DSC measurements confirmed that the extracted polysaccharides had the features of alginate and fucoidan. 1H NMR data revealed that extracted alginate had an M/G ratio of 4.5 and η

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
