Abstract

The effect of oven, solar and sun drying methods on the mineral properties of the Ethiopian Pepper was determined by conducting a study at the Department of Horticulture, Kwame Nkrumah University of Science and Technology (KNUST) using a Completely Randomized Design (CRD). The mineral properties analyzed were, calcium, iron, magnesium, sodium, and zinc. Solar dried Ethiopian pepper, had significantly higher (p ≤ 0.01) calcium (0.38%) as compared to that of oven and sun-dried Ethiopian pepper. Iron level (68 mg/kg) was relatively highest in solar dried Ethiopian pepper whiles magnesium content was highest in oven dried Ethiopian pepper (0.25%). Sodium (1.50%), and zinc (41.75 mg/kg) were recorded for oven dried Ethiopian pepper. Ethiopian pepper dried under oven and solar drying methods retained higher levels minerals.
