During Storage written by Azizah Osman and published by . This book was released on 1996 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Starfruits (Averrhoa carambola L.) variety B10 with a colour index between 2 and 3, obtained from a fruit exporter in Serdang, Selangor, were used in this study. The fruits were subjected to different postharvest treatments namely chilling injury (3=1 Cl; 65-85% RH for 12 h), mechanical injury (dropping the fruits from a height of 1.5 m) and hydrocooling (0-3 C, in ice water for 12 h) before storage at optimum condition (10+1 C; 85-88% RH). Untreated fruits were used as control at both optimum and ambient (27+1 C; 60-80% RH) conditions. The physico-chemical changes studied during storage were texture, polygalacturonase (PG) activity, colour, pH, titratable acidity, total soluble solids, ascorbic acid and total sugar content.

Available in PDF, EPUB and Kindle. Book excerpt: The changes in texture, or firmness loss, of starfruit (Averrhoa carambola L. cv. B10) during ripening occur rather slowly relative to most other economically important tropical fruits. Modified atmosphere packaging (MAP) of the fruit in polyethylene film retarded texture changes, as well as it retarded solubilisation and depolymerisation of cell wal polyuronides. The activities of the wall enzymes, B-galactosidase, polygalacturonase (PG) and pectinesterase were suppressed, but the effect of MAP in maintaining starfruit texture and in retarding wal modification appears to be more closely related to changes of B-galactosidase and pectinesterase activity than to PG activity.

Available in PDF, EPUB and Kindle. Book excerpt: Changes in softening and respiratory enzymes activity, and in other related physicochemical parameters were studied during ripening of starfruit (Averrhoa carambola cv B10). B-Galactosidase and pectin methylesterase activity increased during ripening of starfruit. The increase was correlated with changes in fruit softness as well as in the level of soluble polyuronides. Respiratory enzymes studies showed that NADP-malic enzyme activity reached maximum at day 20 and than reduced on the following days. The activity of PEPCase, however, flatuated throught the storage period. The physicochemical changes such as the skin color, total soluble solid, water loss and titratable acidity also registered an increase during ripening. Tissue pH remained unchanged initially, but decreased later during ripening. [Authors' abstract].

This book was released on 1998 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transportation and storage of fresh fruit and vegetables is an international operation for which the available technology must be used to ensure that produce reaches the consumer in the best possible condition. The use of controlled atmospheric conditions, as a way of reducing the use of chemical preservatives and pesticides, has great potential for the reduction of postharvest losses and the maintenance of nutritive value and organoleptic characteristics. The proper application of controlled atmosphere storage is likely to have as great an impact as the introduction of refrigeration technology a century earlier, yet its potential is only just becoming appreciated, despite its use for apples for many years. In this book, the author reviews and condenses the large amount of research on controlled atmosphere storage, going back more than 80 years, in order to provide the most comprehensive reference source on this topic. It traces the history of the technique and the range of conditions currently in use for different fruit and vegetables, and their effect on flavor, quality and physiology. The influence of pests and diseases, environmental factors such as mixtures of gases, and packaging are then described and the recommended controlled atmosphere conditions for a wide range of crops is provided. This book is essential reading for horticultural researchers and food industry staff concerned with transportation, storage and quality. In addition, it is a valuable reference source for students of horticulture, agriculture, engineering, food science and technology, and food marketing, as well as regulatory bodies and consumer groups.

This book was released on 2011-06-30 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: While products such as bananas, pineapples, kiwifruit and citrus have long been available to consumers in temperate zones, new fruits such as lychee, longan, carambola, and mangosteen are now also entering the market. Confirmation of the health benefits of tropical and subtropical fruit may also promote consumption further. Tropical and subtropical fruits are particularly vulnerable to postharvest losses, and are also transported long distances for sale. Therefore maximising their quality postharvest is essential and there have been many recent advances in this area. Many tropical fruits are processed further into purees, juices and other value-added products, so quality optimisation of processed products is also important. The books cover current state-of-the-art and emerging post-harvest and processing technologies. Volume 1 contains chapters on particular production stages and issues, whereas Volumes 2, 3 and 4 contain chapters focused on particular fruit.Chapters in Volume 4 review the factors affecting the quality of different tropical and subtropical fruits from mangosteen to white sapote. Important issues relevant to each product are discussed, including means of maintaining quality and minimising losses postharvest, recommended storage and transport conditions and processing methods, among other topics.With its distinguished editor and international team of contributors, Volume 4 of Postharvest biology and technology of tropical and subtropical fruits, along with the other volumes in the collection, are essential references both for professionals involved in the postharvest handling and processing of tropical and subtropical fruits and for academics and researchers working in the area. - Along with the other volumes in the collection, Volume 4 is an essential reference for professionals involved in the postharvest handling and processing of tropical and subtropical fruits and for academics and researchers working in the area - Reviews factors affecting the quality of different tropical and subtropical fruits, concentrating on postharvest biology and technology - Important issues relevant to each particular fruit are discussed, such as postharvest physiology, preharvest factors affecting postharvest quality and pests and diseases
