Not All Chitosan Oligosaccharides Are Active To Plant

Product: Ultra High Bioactive Chitosan Oligosaccharide (UHB COS)

Origin: Snow Crab Shell from Alaska, America

Molecular Formula: (C6H11NO4)n

Chitosan Oligosaccharide is widely used for medicine, neutriceutical, cosmetic, agriculture, animal health and environment protection. 

Not all Chitosan Oligosaccharides have bioactivity to plant health. Different uses require different product characteristics. The content of ACTIVE Chitosan Oligosaccharide to plant health determines product's bioactivity, efficacy, also compatibility and solubility. Blue Ocean Ultra High Bioactive Chitosan Oligosaccharide (UHB COS) contents more than 90% of ACTIVE Chitosan Oligosaccharide to plant health. This depends on Blue Ocean cutting-edge biotechnologies and high quality raw materials.

• We have innovated unique bioenzymatic hydrolysis technologies for ULTRA HIGH BIOACTIVE Chitosan Oligosaccharide to plant health.

 We only use high quality raw materials from Snow Crab Shell from Alaska, America.

This enables Blue Ocean UHB COS has Well-characterized Molecular Structure and very high content of ACTIVE Chitosan Oligosaccharide to plant health.
