If you've ever wondered whether the ghee in your kitchen is actually pure — you're asking the right question. The Food Safety and Standards Authority of India (FSSAI) regularly finds adulterated ghee in the market. Common adulterants include vanaspati (hydrogenated fat), refined vegetable oils, starch, and even artificial colour. The shocking part: many of these adulterated products come in premium-looking jars and charge premium prices.
These seven tests require no lab equipment. Just things you already have at home.
Test 1: The Palm Test (30 seconds)
This is the fastest test and surprisingly reliable.
Take half a teaspoon of ghee and place it on your palm. Pure ghee melts immediately on contact with body heat — your palm temperature (around 32°C) is enough. If the ghee doesn't melt within 20–30 seconds and stays solid, it likely contains vegetable fat or hydrogenated oil that has a higher melting point.
What pure ghee does: Melts instantly, feels silky, leaves a clean light residue.
What adulterated ghee does: Stays solid longer, sometimes feels gritty or waxy.
Test 2: The Water Test (2 minutes)
Fill a transparent glass with water at room temperature. Drop one teaspoon of melted ghee into it.
Pure ghee solidifies immediately into a single lump and sinks to or floats at the water's surface as a clean globule. Adulterated ghee — especially if it contains starch or milk solids — will cloud the water or break into multiple particles.
Bonus: If the water turns even slightly milky, starch or milk powder has been added as a filler.
Test 3: The Heating Test for Adulteration (3 minutes)
This is FSSAI's own standard test for detecting vanaspati adulteration.
Melt 2–3 teaspoons of ghee in a steel vessel on low flame. Pure desi ghee will turn golden and completely transparent when fully melted, with no residue. It should also produce a clean, nutty aroma — not a sharp or chemical smell.
If you see:
- A brownish or dark residue at the bottom → likely contains milk solids or non-dairy fat
- A sharp, unpleasant smell → likely contains refined oil or chemical additives
- Excessive foam that doesn't clear → may contain water or starch
Test 4: The Fridge Test (30 minutes)
Place your ghee in the refrigerator for 30 minutes.
Pure bilona ghee (made from curd-churned butter) will solidify uniformly and develop a slightly granular or crystalline texture. This granularity is actually a positive sign — it means the fat composition is authentic. Commercial ghee made by the cream-direct method often solidifies too uniformly, almost like shortening.
If the ghee forms two distinct layers — one hard and one soft — it likely contains a blend of different fats.
Test 5: The Colour and Texture Check (10 seconds)
Real desi cow ghee is deep golden-yellow. This colour comes from beta-carotene in the cow's diet — particularly grass and natural fodder. Buffalo ghee, by contrast, is naturally white or very pale yellow (buffaloes don't convert beta-carotene to fat the same way cows do).
If you see:
- Bright, artificially yellow colour in a product sold as cow ghee → artificial colouring added
- Completely white cow ghee → likely comes from grain-fed cows with poor diet, or isn't cow ghee at all
- Tiny white granules when solid → completely normal and actually a sign of genuine bilona ghee
Test 6: The Iodine Test for Starch (2 minutes)
Some manufacturers add starch, wheat flour or arrowroot powder to increase weight and reduce cost.
Melt a small amount of ghee and let it cool. Add 2–3 drops of iodine solution (available at any medical store). If the mixture turns blue or purple, starch is present. Pure ghee with no starch will show no colour change or turn a light brownish-orange.
Test 7: The HCl Test for Vanaspati (5 minutes)
Vanaspati (dalda) is the most common ghee adulterant in India. FSSAI requires that all vanaspati contain added sesame oil to make detection possible.
Take a teaspoon of melted ghee in a glass tube. Add equal amount of concentrated hydrochloric acid (available at hardware stores) and a pinch of sugar. Shake vigorously for 2 minutes and let it stand. If the acid layer turns crimson red, vanaspati is present. Pure ghee will show no significant colour change.
Note: HCl is a strong acid — handle with gloves and in a ventilated area.
What Do These Tests Mean in Practice?
Even if your ghee passes the palm test and water test, those are basic checks. The only way to be completely certain is independent laboratory testing. FSSAI requires commercial ghee producers to test for iodine value, refractive index, saponification value, and presence of vanaspati and argemone oil.
At Chahal Agri Farms, both our Desi Cow Ghee and Buffalo Ghee have been independently tested by Equinox Labs (NABL accredited). Our reports are publicly available and downloadable — you don't have to take our word for it. View our lab reports →

One More Thing: Where Your Ghee Comes From Matters More
These tests catch obvious adulteration. But even technically “pure” commercial ghee can be made by the cream-direct method — where cream is separated from milk and directly heated into ghee. This is fast and industrial. It is not the same as bilona ghee made from curd.
The bilona method (curdling milk overnight, hand-churning with a wooden churner, slow-cooking the resulting butter) produces ghee with a different fat structure, distinct aroma, and natural granularity. No home test will tell you which method was used — but the taste, smell, and texture usually do.
Our Desi Cow Ghee and Buffalo Ghee are made by the traditional bilona method at our farm in Singhpur Sani Village, Sambhal, West UP — in small batches, with no additives, and independently lab tested every batch.
