| Summary: | The aim of the present research was to determine the effect of environmental conditions (biofortification with Mg) and technological processes (freezing, preserving in jars and drying) on the content of nitrates (III) in carrot. Besides this, the amount of human intake of nitrates (III) found in the carrot products analysed was assayed. The effect on environment resulting from the changes in carrot growing technology was not so unambiguous as for nitrates (V) since most NO2¯ was contained in, for example, processed foods from non-biofortified Mg material. The consumption of products was not hazardous to the consumer since it did not exceed Acceptable Daily Intake (ADI) NO2¯. Most nitrates (III) are consumed with dried carrot and least - with carrot preserved in jars. For this reason, one should run a thorough monitoring of the contents of nitrates (III), toxic to humans since new products based on dried carrot material, such as crisps, are launched in the consumer market.
