摘要：

Five varieties of table potatoes were tested with respect to the contents of ascorbic acid, nitrates and nitrites. The potatoes were characterized by a medium level of vitamin C (16.4 mg/100 g) and nitrates (294 mg KNO3/kg), and a high level of nitrites (0.70 mg NaNO2/kg). A significant effect of cultivation year on the content of vitamin C and nitrates in the tubers has been observed. The highest level of vitamin C was displayed by the variety Mila which had the lowest content of nitrates. Statistical analysis has shown a significant correlation between the natural content of ascorbic acid and the level of nitrates in potato tubers.
