In nature, there are no absolutely pure food products, that’s why permissible levels of various toxic substances contained in them, including nitrates, are established. In case of exceeding permissible levels of harmful substances in plant products, effective methods for their reduction are sought for. It involves utilizing varieties with low nitrate accumulation, improving agricultural practices through scientifically-based agronomy techniques, and developing methods for processing raw materials and finished products. Nowadays extensive materials on nitrate control in plant products have been accumulated. However, this issue has not yet found a definitive solution and remains relevant. The aim of the study was to determine the nitrate levels in carrots grown on a farm and identify methods for their reduction. The experiment was carried out with a late-maturing carrot variety "Queen of autumn" cultivated in the open soil. Carrot samples from both the field and the storage were collected using standard procedures and examined using a pH meter ionizer, specifically "Expert-001," following the accompanying instructions. The conducted research revealed that the nitrate content in the central part of the carrots was 1.5 times higher than in the peripheral part, with the highest accumulation occurring in the second stage of growth. Storing washed carrots for three months at a temperature of +3°C reduced nitrate levels by 12.5%, while storing unwashed carrots in a vegetable storage at a temperature of 8-10°C increased their content in the peripheral part by 10.0%. Heat treatment of carrots at a temperature of 100°C and atmospheric pressure decreased nitrate levels by 17.1%, steaming by 11.3%, and processing into freshly prepared juice by 57.6%.
