Turmeric Powder TP-K37 — Pure Ground Turmeric Rhizome, Curcumin 4.5 g/100g

Turmeric Powder TP-K37 — Pure Ground Turmeric Rhizome, Curcumin 4.5 g/100g

Turmeric powder TP-K37 is a pure ground turmeric powder made from dried turmeric rhizomes sourced from Yunnan, China. The rhizomes are selected, washed, sliced, dried, and finely ground into a vibrant golden-yellow powder with a warm, earthy, slightly spicy aroma characteristic of turmeric powder. Curcumin content is measured at 4.5 g/100g — well above the 3.0 g/100g minimum — which means more color intensity per gram and stronger natural coloring power in food applications.

This turmeric powder serves two functions for food manufacturers: it is a natural coloring agent that delivers a clean-label alternative to synthetic yellow dyes (tartrazine, sunset yellow), and it is a spice ingredient that adds warm earthy depth to curry blends, seasoning mixes, and savory formulations. The fine particle size ensures even color distribution in dry blends, batters, and liquid systems.

Heavy metals are controlled: inorganic arsenic and lead were not detected in the most recent batch. The product is manufactured under Halal, ISO 9001, ISO 22000, and HACCP certification. For background on curcumin as a food colorant and its regulatory status, see the EFSA food colours overview.

Turmeric Powder TP-K37 Specifications

Applications of Turmeric Powder TP-K37

Recommended dosage: 0.1-3% of total formulation. Use lower range (0.1-0.5%) for subtle coloring, higher range (1-3%) as a primary spice ingredient. The powder disperses evenly in dry blends and hydrates into liquid systems.

Curry Blends and Spice Mixes

Turmeric powder TP-K37 is the backbone of curry powder formulations. At 10-30% of a curry blend, it contributes the characteristic golden-yellow color and warm earthy base note that defines curry powder. The curcumin content of 4.5 g/100g delivers more color intensity per gram than commodity-grade turmeric powder, so formulators can achieve target visual impact at lower inclusion rates. In commercial garam masala, turmeric powder at 2-5% provides the color anchor that distinguishes it visually from plain cumin-coriander blends. For reference on turmeric varieties and quality, see the turmeric overview.

Natural Food Coloring

As a natural yellow colorant, turmeric powder TP-K37 replaces synthetic dyes in applications where clean-label positioning matters. At 0.1-0.5%, it delivers a warm golden-yellow hue to rice mixes, noodle doughs, snack seasonings, soup bases, and sauce formulations. The curcumin in turmeric powder is oil-soluble, so for oil-based systems it should be pre-dispersed in the lipid phase. For water-based applications, turmeric powder disperses more evenly when pre-blended with other dry ingredients. Compared to synthetic tartrazine (E102), turmeric powder TP-K37 at 0.3% achieves a comparable visual yellow intensity in dry rice seasoning mixes.

Golden Milk and Beverage Applications

Turmeric powder TP-K37 is used in golden milk (turmeric latte) mixes, wellness tea blends, and functional beverage powders at 0.5-2%. The powder disperses into hot milk and water-based systems, imparting a warm golden color and earthy spice character. In instant golden milk powder formulations, TP-K37 at 8-15% of the dry mix, balanced with cinnamon CP-K38, ginger, and black pepper, creates a complete beverage base that dissolves in hot milk.

Snack Seasoning and Coating

Dust turmeric powder TP-K37 onto oil-coated snacks at 0.5-2% of the seasoning blend for a natural golden color and warm spice note. It pairs with chili, cumin, and garlic profiles in savory snack applications. The fine particle size ensures even coating without gritty mouthfeel. In turmeric-flavored popcorn seasoning, TP-K37 at 3-5% of the seasoning blend, combined with salt and a touch of black pepper, delivers a recognizable turmeric profile.

Meat and Poultry Processing

Incorporate turmeric powder TP-K37 into marinade systems, sausage seasonings, and processed poultry formulations at 0.1-0.5%. It contributes a natural warm golden tone to the finished product without competing with primary meat flavor profiles. In commercial chicken tikka marinade powders, TP-K37 at 2-4% provides the characteristic yellow-orange color that consumers associate with the product.

Curcumin Content and Coloring Power

Curcumin is the principal coloring compound in turmeric powder. The curcumin content of TP-K37 is measured at 4.5 g/100g by HPLC, which is 50% above the 3.0 g/100g standard minimum. This directly impacts formulation economics: a turmeric powder with 4.5% curcumin delivers the same color intensity at roughly two-thirds the dosage of a commodity-grade powder with 3.0% curcumin. For food manufacturers buying turmeric powder primarily as a colorant, the curcumin content specification is the key buying criterion. For technical reference on curcumin analysis methods, see the Codex Alimentarius standards for spices.

Frequently Asked Questions

What is the curcumin content of TP-K37 and how does it compare to standard turmeric powder?

TP-K37 measures 4.5 g/100g curcumin by HPLC, which is 150% of the 3.0 g/100g standard. Commodity-grade turmeric powder sold for culinary use typically ranges from 2.0-3.5% curcumin. The higher curcumin content of this turmeric powder means more coloring power per gram and potentially lower usage rates in formulations.

Can TP-K37 turmeric powder replace synthetic yellow dyes?

At 0.2-0.5%, this turmeric powder provides a warm golden-yellow color comparable to tartrazine (E102) at typical usage levels. Turmeric powder does not produce the bright lemon-yellow of tartrazine — it is a warmer, more orange-toned yellow. It also contributes a mild earthy flavor, which synthetic dyes do not. In applications where a flavor-neutral yellow colorant is needed, curcumin extract may be more suitable than whole turmeric powder.

Does TP-K37 contain any additives or anti-caking agents?

No. TP-K37 is pure ground turmeric rhizome. No additives, preservatives, color enhancers, anti-caking agents, or flow agents are used. The moisture content of 4.89% naturally maintains free-flowing characteristics.

How light-sensitive is turmeric powder? Does curcumin degrade during storage?

Curcumin is photosensitive and will degrade when exposed to direct sunlight over extended periods. Stored in sealed packaging away from light at normal warehouse conditions (below 25°C), the curcumin content of this turmeric powder remains stable through the 18-month shelf life. Avoid storing in clear containers or near windows.

Is turmeric powder TP-K37 suitable for Halal production?

Yes. The product is manufactured under Halal certification. It is a single-ingredient plant-based product with no animal-derived processing aids and no alcohol in the production process.

How does Yunnan turmeric compare to Indian turmeric?

Yunnan turmeric is a Curcuma longa variety grown in the high-altitude regions of Yunnan province. The curcumin content of 4.5 g/100g is comparable to Alleppey-grade Indian turmeric. Yunnan turmeric typically has a slightly brighter yellow-orange hue and lower volatile oil content, which makes it well-suited for applications where color is the primary function.

Can TP-K37 be used in beverage applications?

Yes. This turmeric powder disperses into hot water and milk-based systems. For clear beverages, note that turmeric powder will leave fine sediment — a curcumin extract or filtered infusion is more appropriate for transparent applications. For opaque beverages like golden milk lattes and smoothies, the powder disperses well.

What are the MOQ, lead time, and sample policy?

MOQ is 1 MT. A 1 kg evaluation sample is available on request. Standard lead time is 15-20 working days. Our trade team can provide current production scheduling and accommodate rush orders where possible.
