1. Visual inspection:
The first step in checking ghee purity is a visual inspection. Pure ghee should have a golden yellow color and a smooth texture. If the ghee appears too pale or has an unusual color, it may indicate adulteration. Additionally, pure ghee will have a clear layer of oil on top when stored.
2. Smell test:
Ghee has a distinctive, nutty aroma that sets it apart from other fats. When you smell pure ghee, it should evoke a warm, inviting scent. If it smells rancid or lacks that signature aroma, it might not be pure.
3. Taste test
While you should be cautious about tasting unknown products, a small taste of ghee can reveal a lot. Pure ghee has a rich, buttery flavor with a hint of nuttiness. If the taste is bland or has a strange aftertaste, consider it a sign of potential adulteration.
4. Water solubility test:
A simple water solubility test can help you check for impurities. Take a spoonful of ghee and dissolve it in a glass of cold water. Pure ghee will float on the surface and not mix with the water. If it disperses or forms clumps, it may contain adulterants.
5. Refrigeration test:
Place a small amount of ghee in the refrigerator for a few hours. Pure ghee solidifies uniformly, while adulterated ghee may exhibit inconsistent solidification. If you notice separation or unusual texture after refrigeration, it could be a sign of impurities.
