Ragi Purity & Dye Audit
Ragi (Finger Millet) is high-risk for adulteration with artificial red dyes (like Rhodamine B) to look more "premium" and uniform, or may contain iron filings from heavy industrial grinding.
1. The Cotton Rub Test (Whole Seeds):
Rub a handful of ragi seeds with a wet cotton ball. If the cotton picks up a pink or reddish tint, artificial dye has been applied. Natural ragi color is stable and does not rub off.
2. The Magnet Test (Flour):
Spread ragi flour on a white paper. Move a strong magnet just above the surface of the flour. If tiny black particles jump to the magnet, the flour is contaminated with iron filings from the grinding stones/machinery.
3. The Water Soak (Color Bleed):
Soak a spoonful of ragi in warm water for 15 minutes. If the water turns bright pink or red immediately, suspect artificial coloring. Natural ragi color leaches very slowly and turns the water a pale brownish-pink.
4. The Grit and Sand Check:
Dissolve a spoonful of ragi flour in a glass of water. Pure ragi starch will settle slowly. If a layer of heavy sand or grit settles instantly at the bottom, it indicates poor cleaning or intentional adulteration with stone dust.
Quick Safety Tips
- Perform the magnet test to detect harmful iron filings
- Avoid ragi that releases a bright pink color into water
- Wash whole ragi seeds 3-4 times to remove surface grit and dust
- Prefer "Sprouted" ragi flour for maximum nutritional bioavailability

Frequently Asked Questions
Why is Ragi called a "Superfood"?
It is exceptionally high in Calcium (more than milk per gram), iron, and essential amino acids. It is also gluten-free and has a low glycemic index.
What is sprouted Ragi?
Soaking and germinating the seeds increases the availability of iron and calcium while reducing anti-nutrients like phytates.
Does ragi color the water naturally?
Natural ragi will only slightly cloud the water after long soaking. Immediate pink or red leaching is a sign of artificial dye.
How to detect sand in ragi?
Stir the ragi in a bowl of water; pure grains float or sink slowly, while sand and stones settle immediately at the bottom.
Is darker ragi better?
Not necessarily. Natural ragi varies from light to dark brown. Look for consistency and the absence of artificial shine.
How to store ragi flour safely?
Store in an airtight glass container in a cool, dry place. Ragi flour can go rancid due to its fat content if exposed to heat.
