Red and brown seaweeds extracts: A source of biologically active compounds
Food Chemistry, 2022The 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.

Antioxidant activities of enzymatic extracts from brown seaweeds
Bioresource Technology, 2005Potential 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.

Characterization of polysaccharides extracted from brown seaweeds
Carbohydrate Polymers, 2007Abstract 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 ...

Brown Seaweed Extracts (Alginates)
2022Alginates, 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.

Rheological characterisation of polysaccharides extracted from brown seaweeds
Journal of the Science of Food and Agriculture, 2007AbstractHydrocolloids 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.

The Antioxidant Properties of Brown Seaweed (Sargassum siliquastrum) Extracts
Journal of Medicinal Food, 2007Antioxidant 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 scavenging, metal chelating effect, reducing power effect, and total phenolic compounds.

Dietary Brown Seaweed Extract Supplementation in Small Ruminants
2019Brown 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.

Flowering gene regulation in tomato plants treated with brown seaweed extracts
Scientia Horticulturae, 2021Abstract 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 ...

Extraction and characterization of protein from Irish brown seaweed Ascophyllum nodosum
Food Research International, 2017This 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.
