Product Introduction
Natural Turmeric Extract | 95% Curcuminoids | Botanical Raw Material
Curcumin 95 Natural Turmeric Extract Powder is obtained from the rhizomes of Curcuma longa L. through an extraction and concentration process. The resulting botanical ingredient is standardized to a defined curcuminoid level for use as a functional raw material.
It is different from ordinary turmeric powder, which represents the ground plant material. An extract provides a more concentrated ingredient profile and a defined marker for technical evaluation.
For manufacturers and ingredient distributors, this distinction is useful when developing formulations, qualifying raw materials, or establishing a consistent purchasing specification.

How the Extract Is Produced
Turmeric rhizome is the starting botanical material.
A simplified process is:
Rhizome → Extraction → Concentration → Drying → Testing
The process separates and concentrates the naturally occurring curcuminoid fraction. Testing then provides a basis for confirming the stated specification.
This is one of the main differences between an extract and ground turmeric. The two materials may share the same botanical origin, but their processing and resulting composition are not the same.
Curcuminoids in Turmeric
Curcuminoids are the characteristic group of compounds associated with turmeric. The principal members are:
Curcumin
Demethoxycurcumin
Bisdemethoxycurcumin
For this ingredient, the stated standardization is 95% curcuminoids.
When comparing materials from different sources, the reported percentage should be reviewed together with the analytical method and specification basis. Similar wording on a product label does not necessarily mean identical raw materials.

Key Points for a Technical Inquiry
A useful inquiry should describe what the finished formulation actually requires.
Information may include:
Botanical name
Plant part
Target curcuminoid level
Analytical method
Physical form
Required quantity
Sample requirement
Documentation requirements
Any additional quality parameters
This gives the supplier enough information to quote against a defined requirement rather than making assumptions about the intended grade.

Quality and Analytical Review
HPLC is used for the stated curcuminoid analysis.
Other parameters can be included in a quality program where required, such as:
Moisture
Microbiological testing
Heavy metals
Residual solvents
Pesticide residues
The actual testing requirements should follow the agreed product specification and the customer's quality standards.
For a new material, the review can move from:
Sample → Analytical Data → COA → Internal Approval
This provides a practical record for technical qualification.
Creating a Consistent Raw Material Standard
Once a material has been evaluated, the approved requirements can be documented for future orders.
A basic raw material standard may identify:
Botanical identity
Plant part
Curcuminoid level
Analytical method
Physical characteristics
Quality limits
Required documentation
Keeping these points documented helps different teams work from the same reference when a new batch is received.
Evaluating a Sample
Sample testing should reflect the intended use of the ingredient.
Depending on the project, the evaluation may include:
Powder appearance
Handling characteristics
Assay results
Available quality data
Behavior during formulation
Process compatibility
This is especially useful during new supplier qualification, where laboratory requirements may be more specific than the information shown on a standard product listing.

Natural Turmeric Extract and Ground Turmeric
Both materials come from turmeric rhizome, but they are processed differently.
| Characteristic | Natural Turmeric Extract | Ground Turmeric |
|---|---|---|
| Processing | Extraction and concentration | Grinding |
| Raw material profile | Concentrated botanical extract | Whole powdered botanical |
| Marker approach | Defined curcuminoid level | Usually not standardized in the same way |
| Technical focus | Assay and extract specification | Botanical identity and basic quality |
The appropriate material depends on the requirements of the formulation and manufacturing process.
Buyers specifically looking for the standalone Curcumin 95 Powder product can use the dedicated Curcumin 95 page as the product-level reference.

Where the Ingredient Can Be Used
The extract can be evaluated for formulations such as:
Dietary supplements
Nutraceutical products
Capsules
Tablets
Powder blends
Botanical formulations
Selected functional food products
Final use should be determined by the formulation developer according to technical requirements and applicable regulations.

A Practical Qualification Process
For a new botanical ingredient, the process can remain straightforward:
Define Requirements → Review Material → Test Sample → Approve Specification → Place Order
After approval, the documented requirements can be retained as a reference for subsequent batches.

Frequently Asked Questions
What is Curcumin 95 Natural Turmeric Extract Powder?
It is a turmeric-derived botanical extract made from Curcuma longa rhizome and standardized to a stated 95% curcuminoid level.
What plant part is used?
The rhizome of Curcuma longa L. is used as the botanical starting material.
How is it different from turmeric powder?
Turmeric powder is produced by grinding the botanical material. The extract undergoes extraction and concentration to obtain a more defined curcuminoid profile.
What does 95% mean?
It refers to the stated curcuminoid standardization. The analytical basis should be confirmed in the applicable specification.
What method is used for analysis?
HPLC is used for the stated curcuminoid analysis.
What should I provide when requesting a quotation?
Provide the required marker level, quantity, sample requirement, packaging preference, documentation needs, and any additional quality parameters.
Can a sample be reviewed first?
Yes. A sample can be evaluated against the technical and formulation requirements before commercial purchasing.
What additional tests may be required?
Depending on the specification, testing may cover moisture, microbiological parameters, heavy metals, residual solvents, pesticide residues, or other agreed requirements.
How can I compare different turmeric extract offers?
Review the botanical source, plant part, marker definition, analytical method, quality data, and agreed specification rather than comparing the quoted price alone.
Can an approved specification be retained for future orders?
Yes. The agreed requirements can be used as a reference when evaluating subsequent batches.
Can Gold Herb discuss bulk requirements?
Yes. Buyers can contact Gold Herb to discuss specifications, samples, documentation, quantities, and commercial supply.
