Postharvest technological treatments of pomegranate and preparation of derived products.

Auteurs : ARTÉS F., TOMÁS-BARBERÁN F. A.

Résumé

During the last few years, the activity in research and development on pomegranate fruit has aimed at the application of new postharvest storage technologies to extend the storage life of pomegranates, keeping the original quality of the freshly harvested fruits. In this way, research has focused on the application of controlled atmospheres, the use of modified atmosphere packaging in polymeric films and the application of thermal treatments during refrigerated storage. These technological treatments were applied to alleviate chilling injury symptoms which occur during the storage of pomegranates below 5 °C. Although the industrial processing of pomegranate is still scarce, research on the development of new products such as minimally processed seeds, jams, juices and jellies has been carried out. This new sector of pomegranate industrial processing will allow the use of fruits with low commercial quality fruits (small size, bruised husks, non-commercial varieties, sun-burnt husks, etc.), that cannot be commercialized today in spite of having good quality juice and seeds, to the preparation of these new products.
