The results of amino acid composition in nabak seed kernels (Martin indicate that the level of histidine was almost similar to that of the seed cor reference pattern: however, the levels of all other essential amino sweet p acid were iower than that of FAO/wHo reference pattern. Also, 6.28 mg the EAS revealed that threonine was the first limiting amino acid highest (20.9) followed by lysine (28.4). The proteins from the studied the stud seeds had a low biological value and are therefore called incom- antinutr plete proteins. Thus, these seeds require supplementation with diets. T complementary proteins if they are to be used as food sources. the liter pepper Antinutritional factors Data on different antinutritional factors detected in lantana and Fatty a sweet pepper seeds and nabak seed kernels are presented in Table 4. Table The phytate content of all seeds was higher than those reported by and other investigators for some leguminous seeds (Martin-Cabrejas acids and others 2009: Embaby 2010). Moreover, the highest level of of whi phytic acid was noticed in nabak seed kernels (4.11 g/100 g). The in lant high level of phytate present in the studied seeds might decrease respect the bioavailability of minerals (especially Ca t and Fe Phytates oils w have also been implicated in decreasing protein digestibility by abund forming complexes and also by interacting with enzymes such as had th trypsin and pepsin (Reddy and Pierson 1994) TIAs for lantana and sweet pepper seeds and nabak seed ker- unsatu nels were 0.63, 2.2 and 2.71 mg/g. respectively. This indicates for la that TIAs of both sweet pepper seed and nabak seed kernels unsatu higher than those reported in some common legume seeds
