Is Your Turmeric Pure? Simple Home Tests to Detect Harmful Adulteration

• Turmeric powder may contain artificial colors like lead chromate, metanil yellow, or fillers like chalk powder.
• Test for lead chromate by mixing with water and observing colored streaks; metanil yellow turns pink with HCl.
• Chalk powder adulteration causes fizzing when mixed with diluted hydrochloric acid.
• Pure turmeric is deep golden-yellow, smooth, and stains skin; adulterated may be dull or grainy.
• Simple water tests: pure turmeric settles, leaving clear water; adulterated spreads color or floats.
