Food Grade Turmeric Powder Specifications & Quality Guide

Turmeric Powder Specifications and Quality Considerations for Industrial Use


Raw Material Overview

Botanical name: Curcuma longa L.

Part used: Rhizome

Processing: Cleaning, drying, milling

Appearance: Yellow to orange-yellow powder

Raw material identity and particle size distribution are essential factors affecting both processing performance and final product consistency.


Quality Parameters

Key parameters typically evaluated include:

Particle size (e.g., 50–100 µm, 80–100 mesh)

Moisture content

Color uniformity

Microbial limits

Heavy metal compliance

Research on turmeric processing confirms that particle size optimization improves extraction efficiency and downstream performance, particularly when turmeric powder is used as a precursor for further extraction.


Processing & Extraction Relevance

Scientific studies using supercritical CO₂ extraction demonstrate that turmeric powder with controlled particle size enables:

Improved mass transfer

Higher extraction efficiency

Stable curcuminoid purity

Under optimized conditions, curcumin purity can reach over 95%, highlighting the importance of raw material quality even before extraction.


Application-Oriented Specifications

Turmeric powder may be supplied for:

Food-grade applications

Nutraceutical formulations

Further extraction and processing

Specifications can be adjusted depending on the intended use.


Documentation & Compliance

Commonly available documentation includes:

Certificate of Analysis (COA)

Specification Sheet

MSDS / SDS


Packaging & Supply Options

Bulk packaging for industrial use

Customized particle size upon request

Stable supply for long-term sourcing
