The aim of the work is to monitor fruit and vegetable products on the nitrates content and to recommend measures for their reduction. The results of the testing of nitrates in vegetables and fruits that are mostly used in Ukraine in the human diet were represented. The control of nitrates content was carried out applying the potentiometric method with nitrate selective electrode and ionometer-160. The dynamics of the content of NO3-ions in the beet, carrot and other vegetable juices was studied. The monitoring of nitrates showed that various vegetables and fruits have unequal ability to accumulate nitrates. Their number in beet, carrot and other vegetable juices does not change significantly in two hours. The effective means of nitrate reduction in fruits and vegetables (beet and carrot) is the removal of the top layer in the sample
