Product Introduction

Chitosan Oligosaccharide Powder (COS) also known as Chitooligosaccharide is an advanced enzymatic breakdown product of chitosan which is obtained from the shells of shrimps and crabs or from fungal mycelia. CAS Number 148411-57-8.

The conventional chitosan has a molecular weight more than 50 kDa and requires acidic solutions for disintegration. The molecular size of COS is reduced to less than 3,000 Daltons by enzymatic hydrolysis . At neutral pH, it is entirely water soluble.

This structural difference allows for speedy absorption by the human and plant systems. It is a tiny molecule and because of this it can cross cell membranes very efficiently and thus immediately increases biological activity in human health and in agricultural applications.

Third-Party Test Report

All the batches are tested in-house and verified by authorised third party agencies like SGS, Eurofins etc.

Testing includes the following areas:

· Detection of pesticide residues

· Heavy metals analysis

· Safety in microbiology

· Nutrition labelling

· Optical rotation, specific

· Natural source verification

Internal testing is performed on HPLC, UV spectrophotometry and GC equipment. All batches are traceable and documented before being shipped.

Key Chitosan Oligosaccharide Powder Details

Chitosan Oligosaccharide Powder Advantages

Full Water Solubility at Neutral pH

This powder is very different than conventional chitosan in that it is completely water soluble and does not need an acid to dissolve. This allows it to be used directly with aqueous formulations – capsules, functional drinks, foliar sprays, hydrogels.

Better Bioavailability

Substances below 3,000 Da may easily pass through gut walls and plant cell membranes. This means your formulation will deliver actives to where they’re needed, without loss due to poor absorption.

Enzymatic Hydrolysis Production

Enzymatic processing is more efficient than the chemical hydrolysis techniques in the regulation of molecular weight, ash content and biological safety. This is vital for compliance with regulatory requirements in the food and agriculture industries.

Flexibility in Allergen Sourcing

Fungal derived COS (from Aspergillus niger) is available as an alternative to shellfish derived material for clean label or allergen sensitive markets.

General Market Certifications:

Open access to US, European and South-east Asian markets. Certified KOSHER, HALAL, ORGANIC (EU & NOP), ISO9001, ISO22000, BRC, cGMP and FSSC22000.

Chitosan Oligosaccharide Powder Application

Precision Agriculture (Bio-stimulant)

COS functions as an elicitor for plants at parts-per-million levels. It induces the salicylic acid and jasmonic acid pathways which activate the plant immune response to fungal diseases such as Fusarium and Phytophthora. It also increases resilience to drought and cold stress and promotes root growth.

Nutraceuticals & Dietary Supplements

It has a low molecular weight, so it can go directly into the bloodstream, where it helps to activate macrophages and NK cells and assist the immune system. It also works as a prebiotic to help maintain balance of gut flora and is used in blood sugar management formulas.

Functional Animal Nutrition

COS preferentially boosts Bifidobacteria and Lactobacilli in cattle and aquaculture production. The cationic charge of COS destroys the cell walls of E. coli and Salmonella. Therefore, feed conversion ratios (FCR) are increased and the need for antibiotics is decreased.

Advanced Cosmeceuticals

Anti-aging serums and wound-healing creams use small molecular size to penetrate the skin barrier, increase collagen synthesis, and reduce local inflammation. Its natural antibacterial qualities also lend themselves to preservation roles in clean-label cosmetics.

Production Process

1. Raw Material Selection – Marine crustacean shells or fungal mycelia are collected and checked for quality

2. Deacetylation – Chitosan is formed via deacetylation of chitin in controlled alkaline circumstances

3. Enzymatic Hydrolysis – Chitosanase enzyme breaks down chitosan chains to reach a target molecular weight below 3,000 Da

4. Purification & Filtration — Salts, ash & by-products removal to ≥90% purity

5. Spray drying – transforms the purified liquid into a stable yellow-brown powder

6. Quality Testing – All batches are checked for purity, heavy metals, microbiological and pesticides residues before Packaging

7. Packaging -- Inside fibre drum, 25kg/drum, Double-layer PE bag, sealed for moisture protection

FAQ

Q1: What is the difference between chitosan and Chitosan Oligosaccharide Powder?

A: Chitosan is high molecular weight (>50 kDa) and soluble exclusively in acid. COS is totally soluble in water and has a molecular weight less than 3,000 Da, which gives it a significantly better bioavailability and a greater flexibility of formulation.

Q2: Is the product obtained by enzymatic or chemical hydrolysis?

A: Enzymes are utilised for hydrolysis. This results in a defined molecular weight range, lower ash content and improved biological safety than chemical techniques.

Q3: What is the best molecular weight for agriculture applications?

A: The range of 1,000 to 3,000 Da is the most effective in triggering plant defence receptors for plant immunity and growth promotion.

Q4: Is this product safe for allergenic sensitive markets?

A: The standard product is made from the shells of crustaceans. Fungal derived COS from Aspergillus niger can be supplied upon request if shellfish free material is required.

Q5: How should I store the powder?

A: Store in cool and dry conditions, in firmly sealed aluminium foil bags or PE-lined barrels. The powder is hygroscopic and hence must be kept away from moisture to prevent clumping and loss of activity.

Q6: What is the minimum order quantity and lead time?

A: Normally we pack it at 25kg/drum. Leadtime 3-7 working days for stock items Custom orders can take longer to produce – please Contact Us to check availability.
