It’s hard to imagine an Indian dish without turmeric, the golden spice. Known for its anti-inflammatory and antioxidant properties, turmeric offers many health benefits. Curcumin, the active compound in turmeric, enhances brain function and protects against brain damage. It also supports liver health and helps prevent liver damage.
While turmeric is packed with medicinal properties, many turmeric powders available on the market are adulterated. Chemicals are often added to mimic the natural aroma and vibrant golden colour of genuine turmeric. In fact, even some well-known brands have been reported to adulterate their turmeric powder. The best way to avoid this is to grow your own turmeric or source it from local farmers. Raw turmeric can be washed, dried, and ground into powder at home.
Growing turmeric at home
Kerala’s climate is ideal for turmeric cultivation. Turmeric can be grown in small patches of land or even in grow bags. The crop can be harvested after about a year.
How to store turmeric powder
Turmeric powder can harden if not stored properly. To keep it fresh for a long time, store it in an airtight container and always close the lid tightly. While turmeric has antibacterial properties, certain insects may still infest stored turmeric. This can be prevented by placing a bay leaf in the container.
How to check for adulteration in turmeric powder
Turmeric powder is often adulterated with artificial colours, Metanil Yellow, lead chromate, chalk powder, and wild turmeric. Here are some simple tests to detect these adulterants:
- Lead chromate test
Mix a teaspoon of turmeric powder with water. If the powder settles at the bottom and the water turns a light yellow, the turmeric is pure. Adulterated turmeric will turn the water a bright yellow. - Metanil test
Put a pinch of turmeric powder in a test tube and add a few drops of hydrochloric acid. Shake well. If the mixture turns pink, it indicates the presence of Metanil, which can cause food poisoning, stomach aches, nausea, and indigestion. - Starch test
Add a drop of iodine solution to a boiling mixture of water and a teaspoon of turmeric powder. If the mixture turns blue, starch is present.
‘Golden milk’ for cough and cold relief
‘Golden milk,’ a blend of milk and turmeric, is an Ayurvedic remedy for cough and colds. To make it, use full-fat milk, add a small amount of turmeric powder and pepper to lukewarm milk, and drink it before bed. You can also add ginger and cinnamon for extra flavour and benefits.
