Quality Changes of Thong Dee Pummelo at different Post Harvest Aging Periods ง

Abstract

Thong Dee pummelo fruit samples for the study of hysical and chemical quality changes were collected from 5 farmers' orchard in Sam Phran district, Nakhon Pathom province. The mature fruits were selected from 7-10 years old tree at 20 fruits per orchard (5 trees/orchard and 4 fruits/reee). The indoor aging periods were then assigned to these fruits for 1 day, 1, 2 and 4 weeks after harvest. Results stated that the indoor aging at 4 weeks period consecutively decreased physical qualities such as fruit weight, perimeter, carp thickness, carp weight, meat septum and meat weight, but did not affect seed weight. The 4 weeks aging period significantly improved and increased qualities such as sugar content, sugar : acid ratio, and Ca but did not affect other mineral contents.
