Abstract
The metal contents in 11 cocoa samples collected from different parts of Ondo State, Nigeria, were determined by the use of atomic absorption spectrophotometry. The moisture and ash contents of the samples were in the range 2.0–3.2% and 2.0–3.8%, respectively, the means being 2.5% and 2.9%, respectively.The mean contents of calcium, magnesium, potassium, sodium, manganese, iron, copper and zinc were 25.5, 5170, 2480, 21, 17, 15.8, 8.2 and 62 μg g−1, respectively of cocoa bean as purchased. Magnesium was present at much higher levels than the other metals. In some cases the difference between the mean metal content of samples was significant.Keywords
