Abstract
Proximate composition of wild and on-farm Tamarindus indica Linn fruits (pulp and seeds) were evaluated from three agro ecological zones and land use types in Uganda. The study objectives were: to compare the proximate composition of T. indica pulp and seeds among agro-ecological zones and land use types, and to determine the relationships between the pulp and seeds proximate composition variables among the agro-ecological zones and land use types in Uganda. Samples were analysed using standard procedures for moisture content, total ash, crude protein, crude fibre, crude oil and total carbohydrates. The results show that there were significant differences (P˂0.05) in the pulp and seeds proximate variables between agro-ecological zones except the seed ash content that showed significant difference between land use types. Only total ash contents showed significant interactions between agro-ecological zones and land use types while samples from the Lake Victoria Crescent agro-ecological zone were rich in proximate contents than other zones. The proximate composition revealed the presence of pulp and seed samples for: moisture content (27.40-31.60; 9.00-13.90%), total ash (4.60-5.00; 2.20-2.40%), crude protein (15.70-16.10; 4.30-4.50%), crude fibre (7.10-8.40; 8.00-9.00%), crude oil (0.27-0.29; 2.64- 2.98%) and total carbohydrates (50.20-56.20; 56.20-61.00%) respectively. There were no significant relationships among the proximate variables with agro-ecological zones and land use types. Both pulp and seeds showed good proximate contents, but the traditionally inedible seeds (thrown away after depulping) have more prospects and are recommended for consumption due to the high proximate contents than pulp, but first need to be processed before incorporation into human and animal diets.
