Ghee is one of the most valued ingredients in Indian kitchens—known for its rich aroma, smooth texture, and powerful Ayurvedic benefits. But not all ghee sold in the market is pure. With rising adulteration, it has become essential for consumers to know what makes ghee “pure” and how to test its authenticity at home.
What Makes Ghee “Pure”?
Pure ghee is made by simmering butter or curd-derived makkhan until the milk solids separate, leaving behind rich golden clarified butter. True purity means:
- 100% dairy fat without added vegetable oils
- No artificial flavors, colors, or chemicals
- Traditional churning or slow-heating process
- Natural grainy texture and authentic aroma
Why Purity Testing Matters
Purity is important not only for taste but also for health:
- Health Benefits: Pure ghee supports digestion, immunity, joint health, and hormonal balance.
- Taste & Aroma: Real ghee has a nutty, aromatic flavor that enhances meals.
- Ayurveda Perspective: Pure cow ghee is considered sattvic and used for healing and detox.
- Price Factor: Pure ghee is costlier because it requires more milk and a longer process. Adulterated ghee is often sold cheap.
Rising Adulteration Issues in the Market
Due to high demand and rising milk costs, many brands mix ghee with:
- Low-cost vegetable oils
- Vanaspati
- Animal fats
- Synthetic flavors
- Starches or thickeners
These adulterants not only compromise quality but also pose serious health risks such as heart issues, indigestion, and long-term chronic problems.
Common Adulterants Found in Ghee
Understanding common adulterants helps identify what may be hiding in a cheap or low-quality product.
Vanaspati / Dalda
Vanaspati is hardened vegetable oil often mixed to mimic ghee’s texture.
Impact:
- High in trans fats
- Increases risk of heart disease
- Alters taste and aroma
- Reduces nutritional value
Refined Vegetable Oils
Palm oil, soybean oil, or sunflower oil are commonly added to bulk up quantity.
Impact:
- Affects aroma and melting behavior
- Lowers ghee’s digestive and Ayurvedic benefits
- May cause inflammation with regular consumption
Starch
Some manufacturers add starch to increase thickness or fake granules.
Impact:
- Reduces purity
- Turns sticky when heated
- Can cause digestive issues
Animal Fats
Low-quality animal fats are sometimes added to duplicate the texture of ghee.
Impact:
- Strong unpleasant smell
- Higher saturated fat content
- May cause gastric discomfort and cholesterol issues
Artificial Flavors & Colors
Synthetic ghee flavors and yellow colorants are used to mask impurities.
Impact:
- Chemical accumulation in the body
- Artificial aroma instead of natural fragrance
- Reduced therapeutic value in Ayurveda
Traditional Home Tests to Check Ghee Purity
These simple home methods help you identify if your ghee is genuine without any lab equipment.
Heating Test
Heat 1 teaspoon of ghee in a pan.
- Pure ghee: Melts evenly and turns liquid golden. Leaves no residue and does NOT foam excessively.
- Adulterated ghee: Forms white foam, burns quickly, or leaves grey/white residue due to oils or impurities.
Grainy Texture Check
Check the texture at room temperature.
- Pure cow/A2/Bilona ghee: Has natural granules due to slow heating and milk solids separation.
- Adulterated or highly processed ghee: Appears smooth and uniform with no grainy structure.
Aroma Test
Warm the ghee slightly and smell it.
- Pure ghee: Has a pleasant, nutty, rich aroma.
- Fake or adulterated ghee: Smells chemical-like, overly strong, or artificial.
Refrigerator Test
Place ghee in the fridge for 1 hour.
- Pure ghee: Solidifies uniformly from top to bottom.
- Adulterated ghee: Shows layers—white layers or separated oil indicate mixed vegetable oils.
Palm Rub Test
Take a small quantity of ghee and rub it on your palm.
- Pure ghee: Melts quickly due to body heat.
- Adulterated ghee: Feels sticky and takes longer to melt.
Water Test
Take a glass of water and drop a spoon of ghee into it.
- Pure ghee: Settles at the bottom as a solid mass—because of its density.
- Adulterated ghee: Breaks into small droplets or starts floating, indicating mixed oils.
10 Tests to Check Ghee Purity
| Test No. | Test Name | Method / How to Do It | Indicator of Pure Ghee | Indicator of Adulterated Ghee |
|---|---|---|---|---|
| 1 | Heating Test | Heat 1 tsp ghee in a pan | Melts evenly, turns golden, no residue | Foams excessively, leaves white/grey residue |
| 2 | Grainy Texture Check | Observe ghee at room temperature | Natural granules visible | Smooth, uniform texture |
| 3 | Aroma Test | Smell slightly warmed ghee | Nutty, pleasant, aromatic | Chemical or artificial smell |
| 4 | Refrigerator Test | Place ghee in fridge for 1 hour | Solidifies uniformly | Layer formation, separated oil |
| 5 | Palm Rub Test | Rub a small amount on palm | Melts quickly | Sticky, slow melting |
| 6 | Water Test | Drop ghee in a glass of water | Settles at the bottom as a solid | Floats, breaks into droplets |
| 7 | Melting Point Test (Lab) | Measure temperature at which ghee melts | 28–36°C for cow ghee | Irregular or higher/lower melting point |
| 8 | Fatty Acid Profiling (Lab) | Gas chromatography to check fatty acids | Matches pure milk fat profile | Deviates due to oils/vanaspati/animal fat |
| 9 | Refractive Index Test (Lab) | Measure light refraction through ghee | RI: 1.4500–1.4600 | Out of range indicates adulteration |
| 10 | Peroxide Value / Freshness Test (Lab) | Measures oxidation of fat | Low peroxide value = fresh | High peroxide value = old or adulterated |
Scientific Lab-Based Purity Tests
While home methods are helpful, they cannot detect every type of adulteration. For complete accuracy, scientific laboratory tests are used. These tests follow strict FSSAI standards and measure the chemical structure of the fat to determine purity.
FSSAI-Approved Testing Methods
FSSAI (Food Safety and Standards Authority of India) has defined several scientific methods to check ghee purity. These include:
- Physico-chemical tests (melting point, refractive index, moisture)
- Fat profiling (detecting foreign fats or oils)
- Adulteration detection tests for vanaspati, animal fat, and synthetic compounds
- Freshness tests (acidity and peroxide value)
These tests help confirm whether a sample is 100% milk fat or mixed with plant oils, animal fats, or chemicals.
Fatty Acid Profiling
Every type of fat—cow ghee, buffalo ghee, vegetable oil, or vanaspati—has a unique fatty acid pattern.
Using Gas Chromatography, labs compare:
- Butyric acid level
- Saturated vs unsaturated fat ratio
- Presence of trans fats
- Milk-specific fatty acid markers
Why It Helps:
This is the most accurate scientific method to detect even small amounts of adulterants. If vegetable oils or vanaspati are mixed, the fatty acid pattern immediately changes.
Melting Point Test
Pure ghee has a specific melting point range.
- Pure cow ghee melts at 28°C – 36°C
- Adulterated ghee often melts at higher or irregular temperatures due to added oils or vanaspati.
Why It Helps:
The melting point reveals the consistency and composition of the fat. Mixed oils change the melting temperature noticeably.
Refractive Index Test
The refractive index (RI) measures how light passes through the ghee. Pure cow ghee has a known RI range.
- Pure ghee RI: 1.4500 – 1.4600
- Mixed oils: Have a different RI value.
Why It Helps:
Even tiny quantities of foreign oils change the refractive index, making this a reliable adulteration indicator.
Peroxide Value (Freshness Test)
The peroxide value measures oxidation, which tells how fresh the ghee is.
- Fresh pure ghee: Almost zero peroxide value
- Old or adulterated ghee: Higher peroxide value, showing spoilage or poor-quality oils
Why Lab Reports Are Most Reliable
- Detect adulterants invisible to home tests
- Follow standardized scientific methods
- Accurate, quantifiable results
- Accepted in legal, commercial, and export checks
Lab testing is the gold standard when you want 100% certainty about ghee purity.
How to Read a Ghee Label to Ensure Purity
A smart buyer should always check the label before buying ghee. Here are the key elements to look for:
✔ A2 / Bilona / Grass-Fed Mention
These terms indicate:
- Traditional preparation
- Milk from indigenous cows
- Higher nutritional value
While not a guarantee, these claims show the brand’s focus on quality.
✔ FSSAI License Number
Always verify if:
- The FSSAI number is printed clearly
- The brand is registered
- It matches the details on the FSSAI website
✔ Ingredients List
A pure ghee label should ONLY mention:
Ingredients: Milk Fat (100%)
If you see palm oil, vegetable oil, flavor, or color → avoid instantly.
✔ No Added Flavors or Colors
Terms to avoid:
- Ghee flavor
- Added color
- Nature-identical flavoring substance
Pure ghee does not need artificial smell or color.
✔ Batch Number & Origin
Premium brands always highlight:
- Farm location
- Cow breed

- Strong smell even at room temperature
✔ Taste
- Rich, smooth, and slightly sweet
- No oily or chemical aftertaste
How to Identify Impure or Fake Ghee
Fake or adulterated ghee shows clear warning signs:
❌ Excessive White Color
May indicate refined oil or animal fat.
❌ Plastic-like Smell
A sign of artificial ghee essence or chemical flavoring.
❌ Watery or Too Liquid
Shows presence of moisture, refined oil, or improper heating.
❌ Turns Rancid Too Quickly
Adulterants oxidize fast, causing foul smell.
❌ Very Low Price
Pure ghee requires 25–30 liters of milk per kg.
If the price is extremely low, the product is almost certainly adulterated.
