Depending on their localization in cereal grain, the proportions of these anti-nutrients in diet can be reduced by decortication, a process which may also modify mineral content and bioavailability. Some of the traditional products cited above necessitate preliminary decortication of grains for either organoleptic or technological reasons (astringency, texture, etc.). Although distribution of biochemical components in the different structures of cereal grains is well known for certain species such as wheat, maize or rice , research on pearl millet is poor. Only two studies give some results on the proportions of the anatomical parts of pearl millet grains and the distribution of some nutrients and phytates in these different parts.
