Proximate analysis of Artocarpus odoratissimus (Tarap) in Brunei Darussalam

Artocarpus odoratissimus samples obtained from three different locations in Brunei Darussalam were analysed for their proximate composition which consists of moisture, ash, total carbohydrate, crude protein, crude fibre, energy content and crude fat. The mineral and sugar (fructose, glucose and sucrose) were also investigated. A. odoratissimus flesh contained 67.9 – 73.4 g/100g moisture (wet basis), 0.6 – 0.8 g/100 g ash (wet basis), 12.0 – 25.2 g/100 g total carbohydrate (wet basis), 1.2 – 1.5 g/100g crude protein, 0.8 – 1.3 g/100g crude fibre (wet basis), 334 – 379 kcal/100g energy content (dry basis) and 85 – 363 mg/kg proline (wet basis). The seeds contain 31.0 - 55.0 g/100g moisture (wet basis), 1.0 – 1.5 g/100g ash (wet basis), 3.2 – 4.7 g/100g crude fibre (wet basis), 5.1 - 6.6 g/100g crude protein (wet basis), 10.1 – 28.1 g/100g crude fat (dry basis), 488– 497 Kcal/100g energy content (dry basis), 1.2 – 2.3 g/100g fresh weight of total carbohydrate and 255 – 476 mg/ kg proline. Mineral content (potassium, sodium, calcium, magnesium, copper, cobalt, nickel, zinc, manganese cadmium and lead) was determined and potassium was found to be the most abundant mineral in both the flesh and the seed. No lead was detected in any parts of the fruit. From the quantification of sugar content, fructose was the dominant type of sugar in Artocarpus odoratissimus flesh (5.8 – 13.7 g/100g). From the range of nutrients, A. odoratissimus is generally comparable with A. heterophyllus, A. altilis and A. integer.
