Some edible forest plants have been recognised as nutritional sources and may support human health. Baccaurea macrocarpa is a forest fruit with limited nutritional information. The nutritional value by determining proximates, minerals, and amino acid profile of skin, flesh, and the seed of B. macrocarpa was investigated through this study. Determination of the proximate composition was executed based on the AOAC. Estimation of energy content in kilocalories (kcal/100 g) was calculated by summing the multiplication of each protein, fat, and total carbohydrate. HPLC determined minerals and amino acids. The results showed that B. macrocarpa fruit contained low levels of ash (0.32±0.03 - 1.64±0.05%), fat (0.24±0.03 - 5.98±0.21%), protein (0.44±0.51 - 2.73±0.11%) but a high level of water (61.99±8.33 - 84.84±7.23%), fibre (7.91±2.31 - 18.83±1.03%), and carbohydrates (13.40±0.32 - 27.66±3.13 %). The consumption of 100 g of this fruit may provide energy intake around 2.9% to 8.8% of the 2000 kcal daily energy requirement. It was rich in macro minerals P (60.88±5.71 - 720.95±54.67 µg/g), Ca (149.94±13.73 - 515.32±23.33 µg/g), and Mg (137.98±14.76 - 315.18±24.51 µg/g), and a sufficient amount of micro mineral Zn (6.68±1.32 - 15.29±3.10 µg/g), Fe (0.02±0.00 - 20.97±17.32 µg/g), Cu (0.75±0.00 - 4.94±0.11 µg/g), dan Mn (0.22±0.00 - 2.42±0.01 µg/g). This fruit contained an adequate amount of essential amino acids and an abundance of nonessential amino acids (ƩTAAE/ƩTAA = 1.02 - 1.64%). In conclusion, the results indicated that this forest fruit is potentially a good source of nutrition.
