The results of received researches showed that the content of nitrates in beet on personal common plots in the suburbs of Krasnoyarsk exceed maxi-mum concentration limit. In beets tubers nitrates are collected not equally: the top and the tip of their root contain more, than in the middle part and the core. Ecological and soil conditions create prereq-uisites for the accumulation of nitrates: sufficient moistening and low temperatures; the lack of illu-mination and high temperatures. The purpose of the study was the research of the influence of types of processing of the beet grown on common per-sonal garden and garden plots of the vicinities of Krasnoyarsk on the decrease in the content of ni-trates. As technological solution of "nitrate" problem it is possible to consider local use of nitric fertilizers under cultures. Harvesting of beet in the second half of a day is considered to be optimal as in the late afternoon the weakening of inflow of mineral nitrogen from roots to elevated part of beet is ob-served. Preliminary processing of beet tubers pro-motes the decrease in the content of nitrates by 32-44 %. Heat treatment of beet is the most pro-ductive for the decrease in nitrates content. At its use in beet of the grade Bordeaux the content of nitrates decreases below maximum concentration limit at the temperature - 80°C; exposure time - 45 minutes; hydration level - 1:4. In the grade beet Cylindrical the content of nitrates below maximum concentration limit decreases at the temperature - 100°C; exposure time 60 - minutes; hydration level - 1:2.
