Maximum sodium and potassium levels were found in butter
(84.0g/g) (Fig. 8) and margarine (50.1g/g) (Fig. 9). These values
are higher than reported earlier studies in the literature [9,16]. The
calcium and magnesium levels in edible oil samples were found in
the range of 174.2–20.8g/g (Fig. 10) and 20.8–0.60g/g (Fig. 11),
respectively. The literature values for calcium and magnesiumwere
reported as 90–12.8 mg/100 g and 175–58.3 mg/100 g [20].
