Lactose crystals of improved purity and reduced color are obtained by washing the lactose crystals in an alkaline wash-bath having a pH within the range of from about 8.5 to about 12.5. The isolated washed crystals exhibit improved purity particularly in the reduction of nitrogen-containing impurities as evidenced by a reduced total Kjeldahl nitrogen content and a substantially white color. |
