Losses of potatoes in cold storage occur in all the potato-producing countries and are caused, in part, by excessive high temperatures during storage, which increase rotting, decay and loss of edible quality and nutritive values. In some cases, freezing or chilling injury caused by low temperatures may be involved. Other serious losses are caused by mechanical injury from careless or rough handling and by shrinkage or wilting because of moisture loss. Diseases and pests, which develop during favourable conditions in cold storage, may also cause losses in the form of rottage, decay, poor germination and deformation. The extent of losses of potatoes in cold storage depends on a number of factors and the most important ones are temperature, humidity, ventilation and the condition of potatoes stored. Therefore, the matter of reducing the storage losses directly leads to the problem of providing more efficient and appropriate storage arrangements for potatoes. An attempt has been made in this review, to critically appraise the types of losses of potatoes in cold storage, their causes, preventive measures and important factors affecting the extent of these losses.
