Tamarind Kernel Powder is derived from the seed of the tamarind tree, Tamarindus indica, one of the most common trees of southern India. The tamarind fruit is a large flat pod which is 10 to 15 cms in length. It contains tamarind seeds, stringy fibrous matter and an acidic pulp. The seeds are a by-product of the tamarind pulp industry. The seed is flat and of irregular shape, being round ovate or obtusely four sided. The kernel, which makes 70% of the seed is covered by a testa having a rich brown colour.
The seeds are cleaned, decorticated, polished and then milled to obtain regular Tamarind Kernel Powder. In order to obtain Deoiled Tamarind Kernel Powder, the flakes of the polished seeds are subjected to an extraction process that brings down the oil content from 7% to less than 1.25% and are then milled into powder.
