Alginate oligosaccharide is produced from natural sources kelp with relatively low molecular weight, is composed of β-D-mannuronic acid (M) and α-L-guluronic acid(G) .It’s the natural algae oligosaccharides.
Alginate oligosaccharide (AOS), produced from alginate by alginate lyase-mediated depolymerisation, is a potential substitute for antibiotics and possesses growth-enhancing effects.
The oligosaccharide OligoG, an alginate derived from seaweed, has been shown to have anti-bacterial and anti-biofilm properties and potentiates the activity of selected antibiotics against multi-drug resistant bacteria. The ability of OligoG to perturb fungal growth and potentiate conventional antifungal agents was evaluated using a range of pathogenic fungal strains.
Alginate is a linear long-chain molecule which is irregularly linked by 1,4-mannuronic acid (M) and 1,4-guluronic acid (G), and its functional oligosaccharide obtained by a certain cleavage reaction For brown algae oligosaccharides. Alginate oligosaccharide is a light yellowish brown powder that is soluble in water and has strong stability.

Benefits & Applications of alginate oligosaccharide
1. Medical field
Alginic oligosaccharides have a variety of biological functions, and according to their medicinal functions, the development of fucoidan oligosaccharides will also increase.
Such as anti-cardiovascular drugs; sodium alginate sulfate sodium salt lipid-lowering antithrombotic drugs; glycoside antiviral drugs; polyglycolic anti-urinary calculi drugs; ancient glycolipids.
2. Food field
Used as a food material or additive in the food industry. Alginic oligosaccharide has the functions of intestine and detoxification, blood sugar lowering, anticoagulation, anti-inflammatory, immune regulation, etc. It can be used as therapeutic food for patients with diabetes, obesity, rectal colon cancer, and habitual constipation. It can also be added to condiments, dairy products, and juices, which not only enriches the taste of the product but also increases nutrition and eliminates heavy metal ions and hypoglycemic activity. Algae oligosaccharides have a wide range of applications in the field of the daily chemical industry due to their biological functional diversity.
3. Feed field
Algae oligosaccharide overcomes all the shortcomings of antibiotics, probiotics, and enzyme preparations in the past. It has a low dosage, is pure natural, has no residue and has strong stability. It can improve the disease resistance of animal organisms, promote animal growth and increase animal nutrition. It is an excellent feed additive.
Animal feed additives: pigs, cattle, chickens, etc. Aquaculture feed additives: sea cucumber, abalone, shrimp, etc. The brown algae oligosaccharide in agriculture can stimulate the plant immune system, improve disease resistance, promote cell activation, and stimulate plant growth.
