New Delhi: Amid rising concerns over food adulteration, the Food Safety and Standards Authority of India has introduced a simple 5-minute home test to help consumers detect adulteration in ghee—one of India’s most widely used kitchen staples.
Why Ghee Purity Matters
Pure ghee is valued for its rich flavour and nutritional benefits. However, adulteration with vanaspati or hydrogenated fats can:
- Reduce nutritional quality
- Affect digestion
- Pose long-term health risks
Simple Home Test Method
The test can be performed easily using basic household items:
Materials Required:
- 1 ml melted ghee
- 1 ml concentrated hydrochloric acid (HCl)
- Half a teaspoon of sugar
- A test tube or small glass container
Procedure:
- Take melted ghee in a container
- Add hydrochloric acid
- Add sugar
- Shake the mixture vigorously for about 2 minutes
- Allow it to settle into layers
Interpreting the Results
- Pure ghee: No colour change
- Adulterated ghee: Acid layer turns crimson red or pink
The appearance of red or pink colour indicates the presence of vanaspati or similar adulterants.

The Science Behind It
The test works on a basic chemical reaction:
- Hydrochloric acid breaks sugar into simpler compounds
- These form furfurals upon dehydration
- Furfurals react with adulterants (like vanaspati or sesame oil)
- This reaction produces a red/pink colour
Pure ghee lacks these reactive compounds, so no colour change occurs.
Tips for Buying Pure Ghee
Consumers are advised to:
- Purchase from trusted brands
- Check for FSSAI certification and proper labelling
- Avoid unusually cheap products
- Look for natural aroma and grainy texture
Empowering Consumers
With adulteration becoming more common, simple awareness tools like this test can help households ensure food safety. The initiative by Food Safety and Standards Authority of India highlights the importance of consumer-level vigilance in maintaining quality and health standards.
