Butter Purity & Fat Test
Butter is often adulterated with cheaper Vanaspati (vegetable fat) or fillers like Mashed Potatoes and Starch to increase bulk.
1. The Melt Test (Fat Check):
Heat a spoonful of butter in a vessel.
- Pure Butter: Melts instantly and turns light brown (caramelizes) quickly.
- Adulterated: If it takes a long time to melt and leaves a white residue or stays pale yellow, it likely contains Vanaspati or vegetable oils.
2. The Iodine Test (Starch):
Add a few drops of Iodine solution to a small amount of melted butter.
- Pure: No color change (remains reddish-brown).
- Adulterated: If it turns blue or purple, it confirms the presence of Starch or Mashed Potatoes.
3. The Palm Rub Test:
Rub a small amount of butter on your palm. Pure butter will melt completely and be absorbed, leaving a clean, milky aroma. Vanaspati will feel "waxy" or "grainy" and leave a sticky residue.
Quick Safety Tips
- Melt test - pure butter melts quickly and turns brown
- Iodine test - blue color indicates starch/potatoes
- Avoid butter that feels "waxy" or sticky at room temperature
- Store in a cool, dark place to prevent rancidity

Common Storage Pests
Dairy Mold (Penicillium spp.)
high riskFungal growth that occurs when butter is exposed to moisture and air.
Detection
- Green, black, or white fuzzy spots on the surface
- Musty, "cheesy" odor
- Discoloration
Prevention
- Always use a clean, dry spoon
- Keep refrigerated in an airtight container
Corrective Action: What to do?
If you see any mold spots, **discard the entire block**. Mold roots can penetrate deep into soft fats like butter even if not visible.

Frequently Asked Questions
Why does my butter smell "sour"?
A sour or pungent smell indicates rancidity due to bacterial growth or poor storage. Discard it immediately.
Is "White Butter" safer than "Yellow Butter"?
White butter is often homemade and less processed. Yellow butter contains added salt and coloring (Annatto). Both are safe if they pass the melt test.
Why does some butter stay soft even in the refrigerator?
Pure butter becomes hard when cold. If it remains soft and spreadable immediately after being in the fridge, it likely contains a high percentage of vegetable oils or emulsifiers used in "spreads" but sold as butter.
What causes the "yellow" color in butter?
Natural butter varies from white to pale yellow depending on the cow's diet. Vivid, bright orange-yellow is usually from added Annatto dye, which is safe but can be used to hide low fat content.
