Nutritional & Functional Ingredients
Haematococcus pluvialis Powder (Unbroken Cell Wall)
Haematococcus pluvialis Powder (Unbroken Cell Wall) is an astaxanthin-containing microalgal biomass ingredient supplied without cell-wall disruption. It is used as a raw material for astaxanthin extraction, carotenoid processing, and specialized nutritional ingredient development. ANADYO supports international B2B buyers sourcing unbroken Haematococcus pluvialis powder from China, with multiple content grades, sample orders, and bulk supply options.
Product Overview
Haematococcus pluvialis Powder (Unbroken Cell Wall) is a dried microalgal biomass ingredient containing naturally occurring astaxanthin.
Unlike cell-wall-disrupted Haematococcus pluvialis powder, this product retains its original algal cell-wall structure. This distinction is particularly important for buyers using the biomass for astaxanthin extraction, further processing, or specialized ingredient development.
ANADYO supplies unbroken Haematococcus pluvialis powder from China in multiple astaxanthin content grades, supporting international ingredient processors, manufacturers, and distributors with sample and bulk purchasing options.

Unbroken vs. Cell-Wall-Disrupted Haematococcus pluvialis
Cell-wall condition is an important purchasing consideration for Haematococcus pluvialis biomass.
Unbroken-Cell Powder
Unbroken-cell powder retains the algal cell-wall structure after harvesting and drying.
The cell wall can restrict access to intracellular astaxanthin, making subsequent cell-disruption or extraction procedures important for certain processing applications.
This form is relevant to buyers purchasing algal biomass as a raw material for further processing.
Cell-Wall-Disrupted Powder
Cell-wall-disrupted powder undergoes processing designed to break the algal cell wall and increase access to intracellular constituents.
Even when two products have similar declared astaxanthin contents, differences in cell-wall condition may affect extraction performance and formulation suitability.
Buyers should therefore evaluate cell-wall status separately from astaxanthin content.
Applications & Processing Considerations
Natural Astaxanthin Extraction
Unbroken Haematococcus pluvialis powder can be used as a feedstock for the production of natural astaxanthin ingredients.
For extraction projects, important considerations include:
- Astaxanthin content of the incoming biomass.
- Cell-disruption requirements before extraction.
- Compatibility with the intended extraction process.
- Astaxanthin recovery and finished-product quality.
A higher astaxanthin assay does not automatically guarantee a higher extraction yield under every processing condition.
Carotenoid Ingredient Processing
Manufacturers producing astaxanthin-rich concentrates or other carotenoid preparations may evaluate different biomass grades according to their technical and commercial requirements.
The selected content grade influences the amount of starting material needed for a target astaxanthin input, while extraction efficiency and downstream processing losses must be considered separately.
Nutritional Ingredient Development
Haematococcus pluvialis is an established source of natural astaxanthin used in nutritional ingredient development.
For projects involving unbroken biomass, manufacturers should evaluate whether additional processing is necessary for the intended formulation and whether the selected material meets applicable market requirements.
Unbroken biomass should not automatically be treated as equivalent to cell-wall-disrupted powder or purified astaxanthin preparations.
Quality Documentation & Analytical Considerations
Astaxanthin Assay by HPLC
Astaxanthin content is tested using High-Performance Liquid Chromatography (HPLC) according to a USP method.
When comparing different astaxanthin raw materials, buyers should review the analytical basis used to report the results.
Relevant factors include:
- Astaxanthin Content: Declared concentration and applicable acceptance range.
- Analytical Method: HPLC procedure and corresponding USP method reference.
- Reporting Basis: Whether the result is expressed as total astaxanthin, free astaxanthin equivalent, or another defined measurement basis.
- Sample Preparation: Treatment of the biomass before analysis, particularly when evaluating unbroken cells.
- Batch Documentation: COA with Specifications for the selected content grade.
Use of a USP analytical method does not independently establish full compliance with a USP product monograph.
Additional Quality Considerations
Depending on the intended application, buyers may also evaluate moisture, microbiological limits, relevant contaminants, storage conditions, and batch consistency.
Astaxanthin is sensitive to environmental conditions including light, heat, and oxygen. Packaging, transport, and storage requirements should therefore be reviewed for the selected material.
Certification & Supplier Qualification
For buyers requiring Halal, Kosher, FSSC 22000, ISO 22000, HACCP, GMP, or other relevant manufacturing documentation, ANADYO can review the requirements against the selected product and supply source.
Certification availability, validity, and product or manufacturing-site coverage must be verified before confirmation.
FAQ
Is unbroken Haematococcus pluvialis powder the same as astaxanthin extract?
No. Unbroken Haematococcus pluvialis powder is algal biomass retaining its cell-wall structure, while astaxanthin extracts are processed preparations obtained from suitable starting materials.
These products differ in composition, processing requirements, and intended uses.
Does HPLC testing according to a USP method mean the powder is USP grade?
Not necessarily. The analytical method describes how the relevant content is determined. Full USP monograph compliance requires the material to meet the applicable monograph's identity, definition, assay, and other requirements.
What information should I provide for a quotation?
Please specify your target astaxanthin content range, estimated quantity, destination country, and intended processing application.
If you have particular analytical, certification, or documentation requirements, include these in your inquiry.
