The increase in the number of power-driven hammer-mills in the rural areas of Southern Rhodesia is causing a rapid reduction in the amount of grain ground by women in the villages, except in the remoter areas, where the main crop is usually sorghum or millet. The meal produced by hammer-mills is substantially straight-run and is usually modified slightly by sifting before cooking, the coarser, branny particles being given to livestock. On the other hand, the traditional method of grinding produces a meal of a low extraction rate, particularly with the most important crop, maize. In a country where 80 yo or more of the calories come from cereals, the new method of grinding must cause an appreciable change in the nutritive value of the diet. The traditional methods of grinding were therefore investigated to establish the amounts of calcium, phosphorus, iron, thiamine, riboflavin and proximate constituents in foods ground in that way. There appear to have been few such studies elsewhere in Africa. Williamson (1955) describes methods used in Nyasaland and refers to the work of Scott in Tanganyika, but no analytical figures are given. Recently, Ellis (1959) has given some figures for Nyasaland and indicated that the African’s preference for flint maize is justified.
