Crab shells, often discarded as seafood waste, are the raw foundation of our sustainable, traceable, and certified chitosan.
Founded by Bintarna Tardy in 2004, Fresh On Time Seafood is a respected international processor and supplier of quality seafood and chitosan products produced from crab shells.
Our sustainable and disruptive solution is applied across multiple industries, from food to healthcare, cosmetics, agriculture, and water treatment. We are dedicated to providing quality, value, and reliability, and keeping the needs of our customers first.
At Fresh On Time Seafood, we’ve built a transparent and ethical manufacturing process that transforms waste into high-performance biopolymers trusted across pharmaceuticals, agriculture, food, and cosmetics.
As your certified chitosan supplier, we go beyond product delivery, we provide full traceability, documentation (COA, ISO, MSDS), and measurable value aligned with global procurement KPIs and ESG commitments.
Why Chitosan? The Circular Economy Solution
Chitosan transforms seafood waste into a high-value biopolymer, closing the loop in the circular economy. Where others see crab shells as byproducts, we see opportunity.
Our process converts seafood waste into a renewable resource, reducing landfill impact and creating economic value for coastal communities.
Unlike conventional chitosan manufacturers who may rely on mixed waste or third-party sourcing, Fresh On Time controls the entire chain: from catch to polymer.
We source crab shells directly from our seafood operations or certified partners, guaranteeing contamination free, fully traceable raw materials. It’s circular, it’s clean, and it’s designed to minimize waste at every point.
Step by Step: Our Sustainable Chitosan Manufacturing Process
Here’s how we turn discarded shells into high-grade, functional chitosan ready for regulated markets:
1. Ethical Shell Collection
We source crab shells from our vertically integrated supply chain or long-term certified partners. We ensure clean origin, no cross contamination, and full location tagging from harvest to drying.
2. Cleaning & Drying
Shells are washed in filtered water and dried under strict microbial and temperature controls. This step prevents spoilage and ensures stable input material for further processing.
3. Deproteinization
Protein and fat are removed using food grade NaOH at controlled concentrations and temperatures. Monitoring pH and reaction duration here ensures chitin integrity and safe byproducts.
4. Demineralization
We remove calcium carbonate using eco-friendly acid treatment. Unlike manufacturers that use aggressive chemicals, we balance efficiency with sustainability by reducing residual waste and controlling reaction temperatures.
5. Decolorization
For industries requiring white or translucent chitosan (e.g., cosmetics or pharma), we offer non toxic decolorization. We avoid chlorine bleach and banned solvents, using only compliant agents approved under REACH and FDA standards.
6. Deacetylation
This is the core transformation. Chitin becomes chitosan through high pH and controlled heat. We precisely monitor Degree of Deacetylation (DDA) and viscosity, key parameters for your product’s performance.
7. Milling and Sieving
Chitosan is ground and screened to various mesh sizes for different industries from coarse powder for agriculture to ultrafine grades for injectables or wound dressings.
8. Lab Testing and COA
Each batch is lab tested in-house and/or verified externally. Our standard Certificate of Analysis includes:
- Degree of Deacetylation (DDA %)
- Viscosity (cP)
- Moisture Content
- Heavy Metals
- Particle Size
- Microbial Load
- Ash & Impurities
These results are batch linked and digitally traceable.
9. Packaging & Labeling
We use moisture proof, food grade bags with tamper evident seals, printed batch codes, and scannable tags for full logistics traceability.
Is chitosan good for the liver?
Some studies suggest that chitosan, when combined with a low-calorie diet, may help improve liver function and reduce symptoms of non-alcoholic fatty liver disease (NAFLD). In one 8-week trial, participants taking 1.5 g of chitosan daily saw reduced waist size and better liver enzyme levels. These results are promising but still need broader clinical validation.
5 Ways We Make Chitosan Production Sustainable
Sustainability isn’t just a corporate responsibility, it’s how we design our entire operation at Fresh On Time Seafood.
As global industries seek cleaner, more transparent supply chains, our chitosan manufacturing process is engineered to meet those expectations from the very first step.
From raw material sourcing to waste management and emissions transparency, we embed ESG principles into every layer of our production.
Water Treatment and Reuse in Production
Chitosan manufacturing typically requires water for washing, neutralization, and filtration. At Fresh On Time, we’ve installed a closed loop water treatment system to minimize consumption and maximize reuse.
Water used in deproteinization and demineralization is collected, filtered, treated, and then reintroduced into the process.
This not only conserves freshwater resources in our local communities but also ensures that discharged water meets regional environmental safety standards. It’s one more way we align with ISO 14001 and local clean water mandates.
Solar Assisted Drying to Lower Fuel Dependency
Drying is a high energy step in chitosan production. To reduce our reliance on fossil fuels, we utilize hybrid drying systems that integrate solar thermal energy with traditional heating methods.
Our solar-assisted drying systems significantly reduce fuel consumption, contributing to a smaller carbon footprint per kilogram of chitosan produced.
Our investment in solar technology reflects a long-term vision for carbon neutral operations and helps us pass on sustainability benefits to clients with ambitious emissions targets.
Eco Conscious Use of Processing Chemicals
Chitosan production requires alkaline and acidic reagents. We go beyond standard safety practices by choosing reagents that are easier to neutralize and by following the disposal protocols laid out in EU REACH and Asia Pacific environmental frameworks.
All effluents from chemical treatment stages are neutralized and processed in-house to prevent hazardous discharge.
Our internal labs regularly test output water and waste streams to ensure that we comply with both national and international environmental safety limits.
Transparent Carbon Disclosures for ESG Reporting
For businesses required to disclose environmental performance or carbon impact, we provide verified emissions data upon request.
Our carbon accounting follows internationally accepted frameworks like ISO 14067 and supports greenhouse gas (GHG) inventories that factor into your Scope 3 reporting.
More Than Just a Chitosan Supplier
At Fresh On Time Seafood, sustainability isn’t bolted on, it’s built in. Every stage of our chitosan manufacturing process has been reimagined to reduce environmental impact while maintaining the high quality our clients expect.
Our sustainability model supports:

Fresh On Time delivers COAs, traceability reports, and sustainability metrics to keep your audits clean and your supply chain safe.
Is chitosan safe for kidneys?
Early research suggests chitosan may support kidney health, particularly in people with certain conditions like polycystic kidney disease. Its natural properties might help reduce the kidney’s toxic burden. However, current evidence is still limited, and more studies are needed. Use under medical supervision is recommended, especially for those with existing kidney issues.
