dc.description.abstractThere exists a vast array of species, that have great potential but are often neglected and are termed as underutilized species. Underutilized fruits and vegetables are one such potential bio-asset, that could become a major tool in addressing global malnutrition, poverty and economic prosperity of millions of people. The present study covered assessment of nutritional and anti-nutritional constituents of 42 numbers of underutilized vegetables and fruits (28 vegetables and 14 fruits). The selected vegetables also showed significant variations in their biochemical constituents like moisture content (72.82 - 92.84 g 100g-1), ash content (3.82 - 15.37 g 100g-1), crude fat content (1.51 - 8.33 g 100g-1), crude fibre content (1.62 - 24.67 g 100g-1), crude protein content (1.80 - 9.79 g 100g-1%), potassium content (19.30 - 624.30 mg 100g-1), sodium content (2.34 - 234.11 mg 100g-1), calcium content (69.04 - 858.28 mg 100g-1), phosphorus content (25.94 - 579.15 mg 100g-1), iron content (31.34 - 401.34 mg 100g-1), zinc content (0.03 - 8.02 mg 100g-1), manganese content (25.36 - 264.59 mg 100g-1), Vitamin C (as Ascorbic acid content) (25.64 - 366.98 mg 100g-1), total phenol content (0.63 - 6.54 mg 100g-1) and free radical scavenging activity (72.31 - 95.09 %). The selected samples also contained anti-nutritional properties like saponin (0.13 - 1.08 mg 100g-1), tannin (0.23 - 2.79 mg 100g-1), phytic acid (0.16-0.61 mg 100g-1), oxalate (0.14 - 7.23 mg 100g-1). Similar to the vegetables, the selected fruits also showed significant variations in their biochemical constituents such as moisture content (68.96- 92.46 g 100g-1), ash content (1.39-5.38 g 100g-1), crude fat content (0.41-0.56 g 100g-1), crude fibre content (0.61–5.11 g 100g-1), crude protein content (0.51-8.99 g 100g-1),Potassium content (10.00- 982 mg 100 g-1), Sodium content (0.14 -70.99 mg 100 g-1), Calcium content (1.12-463.83 mg 100 g-1), Phosphorus content (4.57 -306.24 mg 100 g-1), Iron content (0.73 -163.30 mg 100 g-1), Copper content (0.14 -6.19 mg 100 g-1), Zinc content (0.24– 28.94 mg 100 g-1), Manganese content (0.15 -14.64 mg 100 g-1), Vitamin C (as Ascorbic acid content) (5.96 - 117.16 mg 100 g-1), total phenol content (21.08 - 900.84 mg GAE 100 g-1) and free radical scavenging activity (59.05- 94.73 %). The selected samples also contained anti-nutritional properties like saponin (0.01–7.98 mg 100 g-1), tannin (0.49–8.44 mg 100 g-1), phytic acid (0.32-8.05 mg 100 g-1) and oxalate (0.71 -28. 05 mg 100 g-1). However, after determining proportionate values of anti-nutritional components and their related nutrients showed lower than critical values for bioavailability of the related nutrients in majority of the selected fruits and vegetables. Hence, this study may be considered as a benchmark for planning future studies in the field of development of nutraceutical formulations in managing the issue of under nutrition and general wellbeing of the population.
