12 - Storage systems and response of citrus fruits

Abstract

Preservation of the natural qualities of fresh citrus after harvest, either for domestic market or for export, is very important. Storage is the most important operation during the marketing of fruit. All operations, including harvesting, pre- or postharvest treatments, packaging, transportation, and temperature and humidity management during handling influence the storage life of fruits. This chapter presents an overview of storage systems and various qualitative changes that occur to citrus fruits. Handling, storage facilities and marketing structures vary greatly among the citrus-producing countries. Compared with many subtropical fruits, citrus fruits have a relatively long postharvest life. Several storage systems have been tried and many of them are being commercially used. Storage techniques are continuously being improved to extend the storage life of these fruits. The increasing demand and higher production of citrus fruits has resulted in a greater emphasis on the design, construction, and management of storage houses. The common storage houses currently in use are an improved and expanded design of simple-framed storage houses. The improved design and installation of sophisticated equipment in refrigerated storage houses have enabled the long-term storage of large quantities of citrus fruits. Controlled-atmosphere (CA) storage is the latest innovation, but prohibitive costs deter its use.
