Antioxidant Activities of Enzymatic Extracts From Brown Seaweeds

Bioresource Technology, 2005
Potential antioxidative activities of enzymatic extracts from seven species of brown seaweeds were evaluated using four different reactive oxygen species (ROS) scavenging assays containing DPPH (1,1-diphenyl-2-pricrylhydrazyl) free radical, superoxide anion, hydroxyl radical and hydrogen peroxide scavenging assay.

Red and Brown Seaweeds Extracts: A Source of Biologically Active Compounds

Food Chemistry, 2022
The biological activities of Porphyra sp., Gracilaria gracilis, Alaria esculenta and Saccharina latissima extracts prepared by enzymatic and ball milling-assisted methods and hot water were evaluated. Enzyme-assisted methods allowed the highest extraction yields.

Characterization of polysaccharides extracted from brown seaweeds

Carbohydrate Polymers, 2007
Abstract The structural characteristics of polysaccharides extracted from Quebec’s seaweed have not been fully established to date. Ascophyllum nodosum, Fucus vesiculosus and Saccharina longicruris were studied in this research. The seaweeds were treated with selective solvents to extract laminaran and fucoidan in mixture (fraction A), fucoidan ...

The Antioxidant Properties of Brown Seaweed ( Sargassum siliquastrum ) Extracts

Journal of Medicinal Food, 2007
Antioxidant properties of brown seaweed ( Sargassum siliquastrum ) extracts were evaluated using various antioxidant measurements, i.e. , inhibitory effect on thiobarbituric acid-reactive substances (TBARS), 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical ...

Brown Seaweed Extracts (Alginates)

2022
Alginates, or algin, is a generic term for the salts and derivatives of alginic acid. This acidic polysaccharide or gum occurs as the insoluble mixed calcium, sodium, potassium, and magnesium salt in the Phaeophyceae, brown seaweeds. Brown seaweed has been used as a food for centuries but the discovery of algin did not occur until about 1880.

Flowering Gene Regulation in Tomato Plants Treated With Brown Seaweed Extracts

Scientia Horticulturae, 2021
Abstract Liquid extracts of several seaweeds possess great potential as biostimulants for use in agricultural plants. Numerous studies have provided evidence of improved growth and yield parameters in crop plants treated with seaweed extracts. Still, there is a shortage of information available on the mechanisms of action of these extracts on plant ...

Rheological characterisation of polysaccharides extracted from brown seaweeds

Journal of the Science of Food and Agriculture, 2007
AbstractHydrocolloids from seaweeds have interesting functional properties, such as thickening or gelling ability. Structural characteristics of polysaccharides extracted from Québec seaweeds have not yet been established. Thus, the determination of the relationship between their structure and rheological behaviour is limited.

Dietary Brown Seaweed Extract Supplementation in Small Ruminants

2019
Brown seaweed (BSW; Ascophyllum nodosum) extract supplement has been reported to positively affect antioxidant activity, vitamin E status, immune cell response, and carcass characteristics in farm animals. Preharvest diet containing BSW has also been reported to reduce fecal shedding of E. coli and other enteric bacteria in livestock.

Extraction and characterization of an alginate from the Iranian brown seaweed Nizimuddinia zanardini

International Journal of Biological Macromolecules, 2018
Sodium alginate from Nizimuddinia zanardini (an Iranian brown algae) was extracted with acid and alkaline solutions, partially and totally hydrolyzed and analyzed for its biochemical composition. 1H NMR spectroscopy, SEC-MALLS, HPAEC and FT-IR were performed to determine its structure and its physico-chemical properties.

Extraction and characterization of protein from Irish brown seaweed Ascophyllum nodosum

Food Research International, 2017
This study investigates traditional and non-conventional methods of extraction of protein from Irish brown seaweed A. nodosum. Acid, alkali, combined acid-alkali with and without ultrasound pretreatment were investigated for extraction of protein from A. nodosum.
