Abstract

The content of 16 essential elements was determined in fresh strawberry fruit, irradiated strawberries and strawberry marmalade. The elemental composition of fresh strawberries was compared with that of irradiated berries and strawberry marmalade. There were significantly higher amounts of sodium, chloride, calcium, iron, cobalt, nickel, copper, zinc and tin in the marmalade than in the fresh and irradiated fruit. Significantly lower amounts of potassium were observed in the strawberry marmalade than in fresh and irradiated berries. No significant differences in magnesium, silicon, phosphorus, manganese and molybdenum were found between control and irradiated fruits and marmalade. No significant differences were observed between the elemental composition of control and irradiated strawberry fruit.
