The Problem with Adulterated Spices
Spice adulteration is the practice of adding cheaper, non-food substances to spices to increase their weight or enhance their colour. This is most common with powdered spices, where it's difficult to spot foreign materials just by looking. These adulterants
can range from relatively harmless fillers like extra starch to dangerous materials like brick powder, industrial dyes, sawdust, and lead chromate. Regular consumption of these substances can lead to digestive issues, food poisoning, and even long-term health problems like liver damage or cancer. Being a vigilant consumer and checking your spices is a simple step towards ensuring your family's health and the authentic flavour of your meals.
Turmeric Powder (Haldi)
One of the most common adulterants in turmeric powder is metanil yellow, a synthetic dye used to give the powder a vibrant, bright yellow colour. Chalk powder is also sometimes used as a bulking agent. The Food Safety and Standards Authority of India (FSSAI) recommends a simple water test to check for purity. Take a transparent glass of lukewarm water and add a teaspoon of turmeric powder. Do not stir it. Pure turmeric will slowly settle at the bottom, leaving the water with a light yellow tint. However, if the turmeric is adulterated with artificial colours, you will see strong yellow streaks as the powder dissolves, and the water will turn a bright, intense yellow.
Red Chilli Powder (Lal Mirch)
Red chilli powder is frequently adulterated with brick powder, sand, or soapstone to increase its quantity and give it a rich red colour. These substances are harmful and can cause serious health issues. To detect them, FSSAI suggests a straightforward method. Add a teaspoon of your chilli powder to a glass of water and let it sit for a minute. Then, take a small amount of the sediment that has settled at the bottom and rub it between your fingers or on your palm. If you feel a gritty or rough texture, it indicates the presence of brick powder or sand. If the residue feels smooth and soapy, it is likely adulterated with soapstone. Pure chilli powder will feel smooth but not soapy.
Coriander Powder (Dhania)
Finely powdered sawdust or even powdered dung are common adulterants found in coriander powder. These materials add bulk at a low cost but compromise hygiene and safety. A simple visual test with water can help you spot this kind of adulteration. Sprinkle a teaspoon of coriander powder on the surface of a glass of water. Pure coriander powder will gradually absorb water and settle at the bottom of the glass. In contrast, adulterants like sawdust and bran are lighter and will float on the surface. This allows you to quickly see if your dhania powder contains unwanted fibrous materials.
Black Pepper (Kali Mirch)
Whole black peppercorns are often mixed with dried papaya seeds, which look strikingly similar but lack the flavour and health benefits of genuine pepper. Papaya seeds are added to increase the weight and volume of the product. The easiest way to check for this is the float test. Drop a spoonful of your black peppercorns into a glass of water. Pure, high-quality black pepper is dense and will sink to the bottom. The lighter papaya seeds, along with any hollow or inferior peppercorns, will float to the top. You can also try pressing a corn; real pepper is hard and resists crushing, while papaya seeds are softer and crumble more easily.
