Lead Chromate Adulteration in Turmeric Powder
Lead chromate (PbCrO₄) is a toxic chemical compound primarily known for its bright yellow color.
Due to its intense yellow hue, it has been historically misused as a cheap colorant to artificially enhance the appearance of various products.
In the context of food adulteration, turmeric powder is a common target. Turmeric is naturally yellow, but lower-quality or diluted versions are often mixed with synthetic yellow dyes, like lead chromate, to make them look more vibrant and appealing to consumers.
Therefore, lead chromate is recognized as a harmful adulterant used in turmeric powder.
