Representative greenhouse-grown powder batches
Quality from culture to release
Quality built into every production step.
Controlled cultivation, route-specific processing and batch-level evidence support Dunaliella ingredient qualification for global programs.
- Cultivation control
- Route-specific processing
- Batch-specific evidence
Supercritical CO₂ oil grades
Identity, potency, metals and microbiology
Low-arsenic powder
Control starts in the cultivation system.
HETCHYN's enclosed glass-greenhouse raceways reduce exposure to open-air contamination and support tighter control of water, salinity, nutrients and the culture environment. That upstream control matters for whole-algae powder, where the complete biomass becomes the ingredient.
- Glass-greenhouse isolation from the open environment
- Monitored water, salinity, nutrients and circulation
- Product-code-specific specification and batch COA
Solvent-free extraction option
Supercritical CO₂ leaves no residual extraction solvent.
This route uses carbon dioxide instead of an organic extraction solvent and reduces thermal stress on sensitive carotenoid isomers. It is available for standard and custom oil grades.
Select a DS-SE grade when solvent-free extraction is a qualification priority. Final potency, carrier and specification are confirmed by product code.
Explore oil gradesBatch release
Four connected views of ingredient quality.
The selected product specification defines the applicable tests, methods and acceptance limits. The COA records the result for the supplied batch.
Confirm the ingredient
Identity, colour, odour and physical characteristics establish the first release layer.
Measure carotenoid potency
Validated HPLC-DAD testing supports beta-carotene content and, where applicable, isomer-profile review.
Control the relevant metals
The applicable specification defines limits for arsenic and other metals, with results recorded by batch.
Verify microbiological limits
Total plate count, mould and yeast, coliforms and specified pathogens are checked as required by grade.
Certifications & compliance
Current credentials, shown with their scope in mind.
