Dietary fibre and physicochemical properties of several edible seaweeds from the northwestern Spanish coast

Abstract

Proximate composition (moisture, ash, protein and oil content), total dietary fibre content and physicochemical properties of three brown and two red edible Spanish seaweeds, namely: Himanthalia elongata (sea spaghetti), Bifurcaria bifurcata, Laminaria saccharina (sweet kombu), Mastocarpus stellatus and Gigartina pistillata were studied. Ashes (24.9–36.4%) were high in all samples. Protein content ranged from 10.9 to 25.7%, being much higher for Laminaria (25.7%) followed by the red seaweeds (15.5–21.3%). Minor components were lipids (0.3–0.9%) in all samples except for Bifurcaria (5.6%). Total dietary fibre content ranged from 29.3 to 37.4% of which 39.1–74.7% was soluble. For brown algae, the soluble fibre contained uronic acids from alginates and neutral sugars from sulphated fucoidan and laminarin. For red seaweeds, the main neutral sugars corresponded to sulphated galactans (carrageenan or agar). Insoluble fibres (7.4–22.7%) were essentially made of cellulose with an important contribution of Klason lignin especially in brown seaweeds (9.5–10.8%). Regarding the main physicochemical properties, swelling and water retention capacity were high in all samples, while oil retention was low, related to the hydrophilic nature of fibre polysaccharides. In conclusion, these seaweeds can be estimated as a good source of food fibre, protein and minerals for human consumption.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Fucoidans are the leading components of the soluble fiber present in brown algae.

    “Fucoidans are the leading components of the soluble fiber present in such kind of algae [96].”
  • Carrageenans can be classified into three groups (kappa, iota, lambda) differing in the quantity and position of sulfate ester substituents and in 3,6-anhydro-d-galactose content.

    “They can be classified into three groups, according to their industrial use (kappa-, iota-, and lambda-), differing in the quantity and position of their sulfate ester substituents, as well as in the 3,6-anhydro-d-galactose content.”
  • Most seaweed polysaccharides cannot be digested by humans and can be considered dietary fiber, constituting 33%-75% of total composition; soluble fractions account for 50%-85% of total dietary fiber content.

    “One of the most important nutritionally relevant components of seaweeds are polysaccharides, most of them cannot be digested by humans, and thus, they can be considered as dietary fiber (33%–75% of the total composition) [96,97]. In turn, soluble fractions account between 50% and 85% of total dietary fiber content [96].”

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.
