This document discusses food adulteration, which refers to intentionally deceiving consumers by reducing a food's quality or adding non-food substances without the consumer's knowledge. It provides definitions of adulterant, food, and adulteration. The objective is to protect public health and consumer interests by eliminating fraudulent practices involving substandard or contaminated foods. Several common foods are tested for specific adulterants, such as testing coffee powder for scorched persimmon stones, dry red chili for Rhodamine B color, and turmeric powder for Metanil Yellow color. Chemical tests are described to identify adulteration in foods like jaggery, milk, sweet potato, and more.
