Tóm tắt: | Potatoes Postharvestis written for potato store managers, packhouse staff, academics
and students wishing to know how potatoes are managed postharvest and what science underlies the practice. The text is based on the personal experience of the
authors, their own research, applied research by others and laboratory work carried out to confirm findings in the field and in store. The book concentrates on the
essential principles of storage, grading and dispatch of potatoes.
The focus is the potato tuber and all of the influences that can affect its final
quality when sold. Background information such as the tuber’s physical development,
its metabolic processes, its susceptibility to damage and disease are provided where
this aids understanding as to why stored crops develop the problems they do.
Potatoes are increasingly being grown all over the world, with the largest
increases in the developing countries. The book is therefore written for an international audience, and includes the Dutch system of high-rate intermittent ventilation
and the Scandinavian and North American system of low-rate continuous ventilation with humidified air. Refrigerated systems of storage in bags, and low-cost naturally ventilated traditional on-farm systems as used in India, Kenya and other
warm areas, are also included.
While many aspects discussed are similar regardless of climate, such as the
physical development of the crop, packhouse practice and quality control, other
aspects are quite different. Different climates affect the diseases likely to be present
on harvested crops. Storage systems in temperate continental zones are designed
primarily to keep crops from freezing and to minimize desiccation when ventilating
with cold dry air. In contrast, stores in maritime areas are designed primarily to
ensure rapid drying of wet crops entering store, prevention of early sprout growth
and the elimination of condensation on stored tubers due to the leakage of warm
humid air into store. In tropical areas storage in the ground and in low-cost structures is common |
