Karuppu Kavuni is a unique and traditional variety of black rice that is native to the region of Tamil Nadu, India. Also known as "Black Kavuni Rice" or simply "Black Rice," it is highly regarded for its distinct color, nutty flavor, and numerous health benefits. This rare rice variety has a deep black or purple-black outer husk and a dark purple bran layer, which gives it its characteristic dark appearance. Nutritionally, Karuppu Kavuni stands out from other rice varieties because it is a rich source of antioxidants, specifically anthocyanins, which give the rice its dark hue. These antioxidants are known for their potential health benefits, such as reducing oxidative stress and inflammation in the body.
