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.
