Besan or Gram flour is made from ground chickpea popularly known as Bengal gram. The chickpeas are graded, treated with oil & water for conditioning, de-husked and split into halves. Then it is cleaned to remove pebbles, broken grains, coloured dals and other impurities. Cleaned dals are sundried to remove excessive water content as 12-14% moisture is optimal. Finally the dals are ground into fine flour. Besan is the main ingredient for a lot of Indian savouries and sweets. It is also used as thickening agent in curries.
