Potatoes play an important role in ensuring global food security. The potato peel, resulting as a by-product from the processing of potatoes, still contains available quantities of nutrient compounds, among which the mineral elements are counted. The purpose of this study is to determine the mineral profile of the potato peel obtained by peeling some local potatoes, in order to use them to enrich the mineral intake of some food products. The total concentrations of Na, K, Ca, Mg, Fe, Mn, Zn and Cu potato peel from potatoes sold in agro-food markets from Timișoara city (Romania) were determined. Preliminary results revealed that 100g of dried potato peel contain appreciable amounts of essential elements: 38.60-82.30 mg/100 g Na, 1856-2531 mg/100 g K, 155-201 mg/100 g Ca, 122-193 mg/100 g Mg, 4.62-10.88 mg/100 g Fe, 0.64-1.22 mg/100 g Mn, 1.61-2.53 mg/100 g Zn, 0.78-1.60 mg/100 g Cu. These values suggest that these by-products, after proper processing, could be introduced into the diet as a source of essential minerals.
