MATURITY AND POST HARVEST STUDY OF PINEAPPLE WITH QUALITY AND SHELF LIFE UNDER RED SOIL (Pages : 69 - 75)

A field experiment was conducted at the Horticulture, Food Technology and Rural Industries and IPM laboratories, Bangladesh Agricultural University during the period from July to September, 2003 to study the maturity and post harvest study of pineapple with quality and shelf life under red soil during storage under Madhupur district. The experiment was laid out in the Completely Randomized Design (CRD) with three maturity stages and six post harvest treatments and with three replications. Changes in different physico-chemical aspect of pineapple fruits and shelf-life were studied during the storage period. Stage-I fruit exhibited the maximum shelf-life (21.05 days), while the minimum shelf-life (12.70 days) was recorded in stage-III fruits. The highest shelf-life (27.33 days) was recorded in stage-I fruits under the low temperature treatment. The higher Juice content (64.65%) edible portion (69.80%), reducing sugar (4.89%), total sugar (13.36%), total soluble solid (12.50%) and pH (3.93%) were obtained from stage-III fruits, while stage-I fruits contained higher ascorbic acid (24.41 mg/100g fruit pulp), moisture content (87.28%) and titratable acidity (0.826%) at initial stage. Among the physico-chemical parameters such as, total weight loss, edible portion, juice content, TSS, and pH increased with the progress of storage period, and total sugar content declined after an initial increased. On the other hand, moisture content, reducing sugar and titratable acidity decreased with the advancement of storage period. Download
