Effect of peeling and cooking methods on quality of beetroots were studied. Six different cooking methods were used: in pot starting with cold and boiling water, in pressure cooker in water and in steam, in acuthermal pot and in microwave oven. The best nitrates and nitrites elution were obtained during cooking beetroots in big amounts of water (in pot starting with cold and boiling water and in pressure cooker in water). Beetroots cooked by these methods received the lowest scores in sensory quality (especially colour). Because beetroots are very popular mostly for their colour these methods shouldnt be used to cook this product. To save specific colour of beetroots it's better to use cooking methods with small amounts of water (in pressure cooker in steam, in acuthermal pot, in microwave oven).
