Abstract

The objective of the study was to determine the chemical composition of Jackfruit (Artocarpus heterophyllus). Ready to eat jack fruits were harvested from the garden of Forestry Department, Michael Okpara University of Agriculture Umudike. The fruit was identified taxonomically by the Head of the Department of Forestry. Standard methods were used to evaluate the chemical constituents of the fruit (pulp and seed). The moisture content of the pulp (89.5g/100g) was significantly (p<0.05) higher than that of the seed (10.3g/100g) but the crude protein, crude fat, crude fiber, ash and carbohydrate of the seed (16.3, 5.3, 4.3, 5.3, 58.4g/100g) were however significantly (p<0.05) higher than those of pulp (3.3, 0.76, 1.1, 1.1, 4.3g/100g).  The calcium and magnesium contents of the pulp were 19.3 and 29.6mg/100g while those of the seed were 40.6 and 53.8mg/100g. The vitamins A and C contents of the pulp (294.8µg/100g, 27.6mg/100g) were significantly (p<0.05) higher than those of the seed (145µg/100g, 12.9mg/100g). The oxalate, phytate, alkaloid, saponin, flavonoid content of the seed were 129,109, 164, 78,139mg/100g while those of pulp were 41, 18, 33, 17, 23mg/100g. The nutrient compositions of jack fruit were comparable to those of most common fruits. Jackfruit seed was found to be richer in carbohydrate, crude protein, fat, fiber, ash and in all the minerals studied than the pulp, while the pulp was richer in vitamins A, C, E, and the B vitamins (B1, B2, B3, folic acid).
