dc.description.abstractTo execute and explore the hidden potential of underutilized fruit crops in terms of nutritional values with the objective to strengthen the nutritional security and to bring out a standard food composition database. The present investigation was carried out to study the fruit morphology and nutrient content to acquire information on its physical characteristics, nutritional and anti-nutritional compositions of forty four (44) underutilized fruit species endemic to the north-east India. In regard to morphological attributes, Dillenia indica recorded the highest fruit weight (407.00 ± 8.24 g) followed by Citrus medica (345.40 ± 10.62 g), both apparently resulting in higher fruit volume (373.33 ± 9.43 ml) and (313.33 ± 9.43 ml) respectively. The maximum fruit length (15.50 ± 0.75 cm) and breadth (10.35 ± 0.05 cm) were also observed in Citrus medica and Dillenia indica. The maximum seed weight (16.94 ± 1.25 g), seed length (4.06 ± 0.15 cm) and seed breadth (2.92 ± 0.03 cm) were found in Spondias pinnata. Dillenia indica recorded the highest number of seeds per fruit (148.83 ± 4.09) as well as highest pulp weight (350.95 ± 8.24 g). Both the Rubus species i.e. Rubus rosifolius and Rubus ellipticus exhibited the highest pulp percentage (98.12 ± 0.48) and (97.65 ± 0.53). The maximum peel weight (288.71 ± 8.62 g) as well as peel thickness (2.08 ± 0.17 cm) was observed in Citrus medica resulting in lowest pulp percentage (15.32 ± 0.23). Highest dry matter (77.20 ± 0.39%) was found in Castanopsis hystrix. Pertaining to nutritional compositions, Elaeagnus umbellata was found to be high in TSS content (24.50 ± 0.41 °Brix), free fatty acid (67.79 ± 1.75 mg KOH/g) as well as rich source of vitamin A (136.22 ± 1.44 mg/100 g) i.e. (4536.02 ± 48.07 IU). Calamus tenuis exhibited the highest titratable acidity (14.41 ± 1.05%). Terminalia chebula was found to be a good source of reducing sugar (8.38 ± 0.07%) and total flavonoid (445.20 ± 1.18 mg/100 g). Spondias pinnata was found to be rich in total carbohydrate (12.51 ± 0.22%) as well as vitamin C (74.16 ± 5.33 mg/100 g). Castanopsis hystrix was found to exhibit highest starch (1764.84 ± 8.85 mg/100 g) as well as cellulose (711.62 ± 7.68 mg/100 g). Total free amino acid (206.67 ± 8.22 mg/100 g) and crude protein (9.92 ± 0.29%) was found maximum in Viburnum foetidum. Pigments viz. chlorophyll, carotenoid and anthocyanin were found maximum in Phoebe cooperiana (0.47 to 0.01 mg/g), Rhus semialata (19.10 ± 0.29 mg/100 g) and Prunus nepalensis (269.01 ± 5.23 mg/100 g) respectively. Highest vitamin B1 (0.22 ± 0.01 mg/100 g) and E (52.53 ± 0.51 mg/100 g) were recorded in Rubus rosifolius and Garcinia lanceifolia. Artocarpus lakoocha was found to be a good source of antioxidant activity (84.58 ± 2.38%) closely followed by Spondias pinnata (84.09 ± 0.62%). Machilus edulis possessed highest fat content (36.44 ± 1.23%) resulting in highest energy (372.71 ± 9.92 Kcal/100 g). With regard to antinutritional factors, Canarium strictum exhibited the highest phenols (902.00 ± 5.72 mg/100 g). Maximum tannins (1059.33 ± 17.46 mg/100 g) and alkaloids (274.27 ± 6.31 mg/100 g) were found in Terminalia chebula and Streblus asper. It was observed that the species Castanopsis hystrix and Viburnum foetidum exhibited higher content of cyanogen (31.04 ± 1.28 mg/100 g) and phytic acid (10.64 ± 0.30 mg/100 g) respectively. The result indicated that all the fruit species studied possessed varying contents in nutritional and antinutritional compositions.en_US
