This Bulletin reviews the limited amount of information that has been recorded relating to the post-harvest technologies of the perishable (non-grain) staple foods that have been developed in the traditional societies of the developing countries of the tropics. These foods are derived primarily from the tropical root crops; cassava, yam, sweet potato and the various aroids; from fruit such as banana and breadfruit; and from the starch reserves laid down by various monocarpic plants (mainly palms such as sago).
