alginate oligosaccharides is light yellow powder, which can dissolve in water and has strong stability. It has a variety of biological functions. It is widely used in medicine, food, feed and agriculture. As a professional alginate oligosaccharides manufacturer and global supplier, Shandong Jiejing Group Corporation has been specialized in manufacturing and exporting alginate oligosaccharides for 56 years. Please be rest assured to buy alginate oligosaccharides from Shandong Jiejing. Any questions or inquiry feel free to contact us by email, you will get response in one working day.

What's alginate oligosaccharides?

alginate oligosaccharides is a product obtained by degrading the molecular weight of sodium alginate through enzymatic hydrolysis of sodium alginate on the production process. In essence, it still belongs to sodium alginate, but it is sodium alginate (sodium alginate oligosaccharide) with a smaller molecular weight, which also contains guluronic acid and mannuronic acid. It is also known as alginate-dereived oligosaccharides and AOS. It have strong water solubility, high stability, low viscosity, strong hygroscopicity, safe and non-toxic physical and chemical properties, and the average molecular weight is below 8000, which is more conducive to absorption.

Effects of alginate oligosaccharides:
Low-molecular weight alginate oligosaccharides have many biological activities, such as anti-tumor, anti-oxidation, antibacterial, growth-promoting etc., and have broad development prospects in the fields of drug development, functional food development, and agriculture.

In agriculture:

  •  Promoting plant growth - promoting seed germination, promoting germination.

  • Alleviating plant abiotic stress  - cold tolerance, drought tolerance, salt tolerance, heavy metal tolerance.

  • having the active effect of elicitors - stimulating the production of phytoalexin and accumulating specific defense substances.


  • alginate oligosaccharides had strong antibacterial activity against three common aquatic pathogens Aeromonas hydrophila and Candida albicans, and showed strong antibacterial activity against Vibrio anguillarum in the late exponential phase. It provides a certain basis for marine oligosaccharides to replace antibiotics and become a new generation of safe, efficient, and non-toxic and side-effect-free feed additives for aquaculture, and has a broad prospect for development and application in aquatic feed.

  • alginate oligosaccharides have antibacterial activity because some bacterial polysaccharide degradation products can act as toxic factors and inhibit cell growth. alginate oligosaccharides at 10-0.3125 g/L can significantly shorten the adaptation period of bifidobacteria, and make bifidobacteria proliferate in large quantities. Therefore, alginate oligosaccharides have good application prospects in the proliferation of bifidobacteria and the development of functional health food.


alginate oligosaccharides are rich in sources, theoretically they are good anti-inflammation substitutes for sLex, sLea and heparin oligosaccharides, and have good potential medicinal value.
