15 Dec Testing The Purity of Ghee
If you are never sure about the quality of the ghee you are consuming, here are some easy methods you can use to test the purity of ghee.
The Heat Test
This test is straightforward but highly effective. All you have to do is heat a teaspoon of ghee in a bowl. If the ghee melts almost instantly and turns dark brown, then the shortening is pure quality. However, if the shortening has taken time to melt and turn a bright yellow color, it is best to avoid this product.
Double-Boiler Method Check
To save on manufacturing costs, some manufacturers mix coconut oil into clarified butter to increase its quantity. Then, to check if the ghee has traces of coconut oil, melt the ghee in a glass jar using the double boiler method. After it has melted, put the jar in the refrigerator for a while until the liquid solidifies. If clarified butter is mixed with coconut oil, the two will solidify in different layers, giving you a warning of its adulteration.
The Iodine Test
Another product that is commonly mixed into ghee is starch. To see if the ghee has been tampered with, add two drops of iodine solution to a small number of melted ghee. When the iodine turns purple, it is a clear indication that the ghee has been mixed with starch and should be avoided. If the ghee you have turns out to be not pure, you should most likely switch your supplier.
