PHYSICO-CHEMICAL CHARACTERISTICS OF SOME MANGO VARIETIES GROWN IN NORTHERN REGION OF BANGLADESH

Abstract

The present study was conducted at the laboratories of the Department of Agricultural Chemistry and Biochemistry in Hajee Mohammad Danesh Science and Technology University, Dinajpur during the period from May, to September, 2007. The objectives of the experiment were to evaluate the pattern of physical and bio-chemical changes associated in 17 mango varieties at three maturity stages. There was a marked variation among the three maturity stages of 17 mango varieties in relation to quantitative characteristics of fruits. The heaviest and lightest fruits were recorded in Mollika and Amropali, respectively. Khirshapath produced the highest size of fruit while Mollika produced the biggest stone. Higher edible portion was recorded in Fazli and Mollika whereas maximum non-edible portion was noted in Misribhog. The variety Misribhog possessed the maximum peel percent. All the varieties were chemically analysed and highly significant differences were recorded among the varieties. Mollika possessed maximum moisture content at premature stage whereas Laxmonbhog had the highest total soluble solid (“ebrix) content at ripening stage. The variety Mollika was top in the list regarding pulp to peel ratio at ripening stage than those at premature and mature stage but Surjapuri and/or Amropali was in top regarding dry matter content at ripening stage than other two stages. On the other hand, maximum total weight loss was noted in Gopalbhog at ripening stage. Vitamin C content in Amropali was the maximum whereas Khuthikhirsha had the highest glucose content at ripening stage than premature and mature stages.
