EVALUATION OF PHYSICOCHEMICAL PROPERTIES AND BIOACTIVE COMPOUNDS OF FIVE MANGO (Mangifera indica L.) VARIETIES IN BANGLADESH

Abstract

Fruits and vegetables are important sources of nutrients for mankind. Among the various fruits available in Bangladesh, Mango occupies a vital place in the human nutrition for its delicious taste and higher nutritious value. This study was conducted to evaluate the quality of five different mango varieties (Fazli, Amrupali, Langra, Gopalbogh and Misribogh) available in Northern Bangladesh. Physiochemical characteristics including moisture, ash, total carbohydrates, total solids, total soluble solids (TSS), pH, acidity, total sugars and ascorbic acid contents were evaluated. The results showed that there were significant (P < 0.05) differences among mangoes of all varieties for physio-chemical parameters. In case of proximate composition, the mango variety Amrupali showed the highest ash content (2.34±0.15) and fat content (1.18±0.13). Protein content (0.94±0.12) and total fiber (2.67%) content was shown to be the highest by Gopalbogh and Misribogh, respectively. The selected mango varieties contained total soluble solids of 12.87~20.55oBrix, pH of 4.45~4.67, titrable acidity of 0.07~0.42%, reducing sugar of 8.40~15.43%, non-reducing sugar of 9.24~10.48%, and total sugar of 18.88~25.12%. Bioactive compounds viz. vitamin C (28.63~40.92 mg/100g) and beta-carotene (0.01593 to 0.02028 mg/g) were found to be significantly varied among the mango varieties. It can be concluded from the results of this study that all the mango varieties are high in nutrition and beneficial compounds for the human health. The study findings would be helpful for the consumers, dietitian and industry policymakers.
