and ash content between 32.7 to 40% and 4.4 to 4.8%, respectively. The nutritional
composition of Nigella seed is also affected by the growing environmental conditions, soil types, and agricultural practices (Atta 2003). Oil, ash, protein, and
carbohydrate content in Nigella seed collected from the local market of Tehran
(Iran) was found to be 31.7, 5.3, 23.0, and 34.9%, respectively (Solati et al. 2014).
Sultan et al. (2009) also reported almost similar content of protein (22.8%), oil
(31.1%), and ash (4.2%) in Nigella seeds. However, Malaysian Nigella seed samples
exhibited 32.06% oil content, lower levels of protein (19.19%), high content of ash
(6.82%), and 35% carbohydrate content (Mohammed et al. 2016). However,
Khoddami et al. (2011) reported considerably different values of protein (20%),
ash (6.27%), fat (37.3%), and total carbohydrate content (30.5%) in Nigella seeds
(Table 13.1).
Similarly, Atta (2003) reported slightly different content of protein (20.8%), oil
(34.8%), and ash (3.7%), while carbohydrate content (33.7%) was observed almost
