EFFECT OF HARVESTING TIME AND VARIETIES ON THE PHYSICOCHEMICAL CHARACTERISTICS OF JACKFRUITS (Artocarpus Heterophyllus Lam.) (Pages : 48 - 57)

An investigation was carried out at the Horticulture farm of Bangladesh Agricultural University to study the physicochemical characteristics of jackfruit at three different harvesting times. Physical characteristics of fruit such as weight of fruit, bulb, seed, rind and axis; skin color, number of bulbs per fruit; nature, flavor and sweetness of bulbs, and chemical characteristics such total soluble solid (TSS), pH, sugar, vitamin C, moisture, dry matter, ash contents of jackfruit bulbs were determined. Matured jackfruits were harvested at three different times, namely early harvesting, mid harvesting and late harvesting and observed that texture, fibrousness, juiciness, flavor and sweetness of bulbs were changed at different harvesting time. Weight of fruit, weight of edible and non-edible portions were also varied at three different harvesting times. Dry matter, ash and non-reducing sugar contents of bulbs were gradually increased with the harvesting times from early to late in the season. At early harvesting time dry matter, ash and non reducing sugar contents were found to be the lowest and the highest at late harvesting time. On the other hand, TSS, vitamin C, moisture, total sugar, reducing sugar, contents of jackfruit bulbs decreased during the time. Again TSS, vitamin C, moisture, total sugar, reducing sugar, non-reducing sugar contents were found to be the highest at early harvesting time and the lowest at late harvesting time. Download
