Abstract

Seaweeds are an excellent source of bioactive compounds, and therefore the use of sustainable and food compatible extraction methods such as enzyme-assisted (EAE) and ultrasound-assisted extraction were applied on Sargassum muticum, Osmundea pinnatifida, and Codium tomentosum. Extracts were evaluated for proximate characterization and biological properties. Higher extraction yields were observed for C. tomentosum EAE (48-62%; p < 0.05 for Cellulase and Viscozyme), followed by O. pinnatifida (49-55%; p < 0.05 except Alcalase) and S. muticum (26-31%; p < 0.05). S. muticum extracts presented the highest nitrogen (25 ± 2 mg/glyoph extract) and total phenolics (261 ± 37 μgcatechol equiv/glyoph extract) contents, whereas higher sugars (78 ± 14 mgglucose equiv/glyoph extract) including sulfated polysaccharide (44 ± 8 mgNa2SO4 acid/glyoph extract) contents characterized O. pinnatifida extracts. A higher effect on hydroxyl-radical scavenging activity (35-50%) was observed for all extracts, whereas S. muticum Alcalase and C. tomentosum Cellulase extracts exhibited higher prebiotic activity than fructooligosaccharides. O. pinnatifida and C. tomentosum EAE showed inhibitory potential against α-glucosidase (38-49%).

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?

  • Marine macroalgae possess a wide range of bioactivities, such as anti-aging, antioxidant, antimicrobial, antiproliferative, anti-inflammatory, antidiabetic, and neuroprotective activity.

    “Due to the presence of biocompounds in macroalgae, they possess a wide range of bioactivities, such as anti-aging, antioxidant, antimicrobial, antiproliferative, anti-inflammatory, antidiabetic, and neuroprotective activity [5,6,7].”
  • Brown algae had higher phenolic content and antioxidant activity than red and green algae.

    “It was shown that brown algae had higher phenolic content and antioxidant activity than red and green algae.”
  • Available data of UAE extraction of macroalgae shows polyphenols and antioxidants are the main extracted compounds, using solvents such as ethanol, distilled water, and methanol with different solid:solvent ratios.

    “Available data of UAE extraction of macroalgae shows that polyphenols and antioxidants are the main extracted compounds from macroalgae (Table 2). Various solvents were used, such as ethanol, distilled water, and methanol with different solid:solvent ratio [7,49,50].”
  • Seaweed extracts possess carbon sources that can be metabolized by Lactobacillus acidophilus and Bifidobacterium animalis; carbon sources are mostly polysaccharides, but not agar, because microorganisms cannot hydrolyze and metabolize it.

    “Results showed that the seaweed extracts possess carbon sources that can be metabolized by mentioned bacteria. The carbon sources are mostly polysaccharides, but not agar, because microorganisms are not able to hydrolyze and metabolize it.”

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.
