One of the easiest ways to check adulteration in turmeric powder is to take a pinch of turmeric powder in your palm and rub it with your thumb for 15-20 seconds. Pure turmeric will stick to your palm, leaving behind a deep yellow colour.
Adulteration of Turmeric Powder
Turmeric is one of the most popular spices used in every Indian household. The demand for organic turmeric powder has been rising each year. But this rise in demand has given birth to a lot of unfair practices.
In 2019, Stanford researchers published a study in Environmental Science & Technology unveiling the presence of the lead chromate pigment in the turmeric powder. The usage of lead chromate has been banned in the food industry due to its correlation with cardiovascular diseases and various other diseases. Hence it is important that you only consume organic turmeric powder that has 100% natural turmeric in it.
Tip: The Bureau of Indian Standards suggests a minimum of 3% curcumin for powdered turmeric. The Divine Foods organic turmeric powder has 5.25% curcumin in it.
There is a huge demand for Indian spices in the world and this demand is increasing year on year. The spice business offers huge profits but it also has a lot of competition which has motivated numerous players in the industry to undertake unethical methods.
Since turmeric is not only used as a flavouring agent it is also revered as Ayurvedic medicine to boost immunity and act as an anti-inflammatory. Hence adulteration in turmeric powder is a huge threat. Turmeric powder is adulterated by:
- Mixing it with chalk powder to increase the volume of the turmeric powder
- Adding metanil yellow which is often used in the making of the ladoos and mithais to add the yellow colour
- Starch is added to the volume of the turmeric powder
