Description
A whole-rhizome standardized extract from turmeric (Curcuma longa) containing both the curcuminoid polyphenol fraction and the turmerone-class volatile oils. Distinct from isolated Curcumin in that the whole-rhizome extract preserves the synergistic volatile oils that some research suggests improve curcuminoid bioavailability and contribute distinct biological activity.
Yellow to orange-yellow free-flowing powder. Partial water solubility; the curcuminoid fraction is poorly water-soluble while the volatile oils contribute aroma and partial lipid-solubility.
We supply food-grade Turmeric Extract from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production. Organic-certified grades are available.
Common market grades include 5 percent Curcuminoids (whole-rhizome grade with preserved volatile oils), 10 percent Curcuminoids (standard supplement grade), 20 percent Curcuminoids (premium grade), and 50 percent Curcuminoids (high-end concentrated grade). For greater than 95 percent curcuminoid content, refer to the separate isolated Curcumin product.
Bulk and reduced-MOQ shipments. Batch-level COA covering total curcuminoids (HPLC), turmerone content, residual solvents, heavy metals, pesticides, and microbiology.
Introduction
Turmeric has been used in Ayurvedic medicine and South Asian cuisine for over 4,000 years. Whole-rhizome turmeric extracts preserve a broader phytochemical profile than isolated curcumin, including the turmerone-class volatile oils (ar-turmerone, alpha-turmerone, beta-turmerone) that contribute the rhizome's characteristic aroma and additional biological activity.
Industrial production proceeds by hot-water or hydroalcoholic extraction of dried turmeric rhizome, followed by concentration and spray-drying to defined curcuminoid content. Whole-rhizome extracts retain meaningful turmerone content; isolated curcumin grades remove the volatile oils during purification.
Recognized as a permitted food ingredient by the U.S. FDA (GRAS), the European Food Safety Authority, and equivalent regulators worldwide. Turmeric is regulated as E100 in the EU as a natural food colorant.
Clinical evidence supports turmeric extract for osteoarthritis pain and inflammation markers at appropriate doses, with growing mechanistic interest in the turmerone fraction beyond the curcuminoids alone. Whole-rhizome formats are favored in some clinical programs that prioritize traditional preparation precedent over isolated-active reductionism.
Strategic positioning combines joint-health and anti-inflammatory dietary supplements, functional foods and golden-milk beverages (the fastest-growing segment), and premium clean-label applications where whole-rhizome positioning is part of the value proposition.
Where it is used
- Joint-health and anti-inflammatory dietary supplements (the dominant commercial application)
- Liver-support and detoxification formulations
- Functional beverages: golden milk lattes, wellness shots, and herbal teas
- Premium fortified foods, nutritional bars, and curry-style ready meals
- Natural food colorant and flavor in clean-label applications
- Cosmetic skincare: anti-inflammatory and brightening formulations
- Veterinary and pet supplements positioned for senior joint health
- Traditional Ayurvedic and TCM product formulations
