The influence of heat treatment on safety of vegetable production

In this paper the influence of heat treatment on the reduction of nitrate content in vegetable crops (cabbage and beets) suburban area of Krasnoyarsk is studied. Agricultural farms, located in suburban area of Krasnoyarsk are the main suppliers of vegetables for the inhabitants of the city. All products are cabbage and beets, these farms have nitrate levels exceeding the MCL. Among the representatives of the higher plants there is a group of families that accumulate significant amount of nitrates. Among families covering the vegetable crops, the highest ability to accumulate nitrate is different from the family of leaf - cabbage, and from the family of root - beets. Development of technologies for reduction of nitrate content in vegetable products is universally relevant and contributes to solving issues of food security of the population. The study of thermal processing of different varieties of beets and cabbage, grown in the suburban area of this major industrial centre, the city of Krasnoyarsk, is pioneer. The purpose of the study is the use of heat treatment of vegetables (beets and cabbage) grown in suburban area of Krasnoyarsk city to reduce the content of nitrates.
