Abstract
Abstract Light-milled, cell-distorted roast and ground coffee wherein said light-milled coffee has a bulk density equal to that of conventional roast and ground coffee products. The product has some cell fracture and partial cell disruption and therefore has increased extractability. The light-milled, cell-distorted roast and ground coffee when viewed in bulk has the appearance of conventional roast and ground coffee but has from 10 to 30% increase in flavor strength. The method of producing this product comprises passing roast and ground coffee through a roll mill under controlled conditions of feed rate, pressure, and roll speed.
