Adulteration in food has been one of the major concerns since time immemorial, as it not only decreases the quality of food products but also leads to harmful health consequences. Tea is one of the most preferred drinks which is being adulterated with harmful materials like artificial colour, azo dye, coal tar dye and many more either intentionally or unintentionally. The present study was designed to evaluate the quality of black tea available in the markets of Kolkata, West Bengal and to detect adulteration in them. Twelve samples of black tea were analyzed to determine the presence of different adulterants. The products containing adulterants were categorized into high priced and low priced tea samples. Analysis indicated that low cost tea contained more adulterants as compared to high cost tea. The current article attempts to increase the general awareness of the population at large about adulteration of tea in addition to the simple techniques available to detect the same. This may henceforth be beneficial for adequate food choice and selection of appropriate quality of food.
