Abstract. In the experiment, we determined the nutritional composition of the fruits of promising apricot varieties growing in the Central Chernozem Region. The objects of the study were the fruits of varieties bred in Russia – Vodoley, Grafinya, Lel’, Pogremok, and Ul’yanikhinsky. Chemical analysis was conducted using titrimetric, chromatographic (HPLC), spectrophotometric, and atomic absorption methods. The water content in the edible part of apricot fruits was 84.8%; ash content was 0.74%; protein content was 0.47%; dietary fibre content was 2%. The highest sugar content among the studied varieties was found in Lel’ and Vodoley varieties – more than 9.0%. Their structural composition was dominated by sucrose (67.1%). The concentration of citric acid in fruits was 0.13–0.93%; apple acid – 0.32–0.48%; vitamin C – 7.0–15.0 mg/100 g; vitamin PP – 0.10–0.14 mg/100 g; vitamin B1 – 0.02–0.07 mg/100 g; vitamin B2 – 0.03–0.08 mg/100 g; carotenoids – 0.7–3.0 mg/100 g; polyphenolic compounds – 25–120 mg/100 g. The content of Na was in the range of 1.06–3.00 mg/100 g; K – 266.9–652.4 mg/100 g; Ca – 19.8–40.3 mg/100 g; Mg – 12.0–21.6 mg/100 g; Fe – 0.30–0.42 mg/100 g; Cu – 0.17–0.49 mg/100 g; Zn – 0.053–0.202 mg/100 g. From the standpoint of the recommended rates, consumption of 100 g of apricot pulp satisfies the daily requirement for vitamin C (80.0 mg) by 8.8–18.8%; consumption of carotenoids (5 mg, in terms of beta-carotene) satisfies the daily requirement for vitamin C by 14.0–60.0%. Ul’yanikhinsky variety is of the greatest interest in this respect, it was characterized by the vitamin C content of 15.0 mg/100 g and carotenoid content of 3.0 mg/100 g. The daily requirement for potassium (2000 mg) with the consumption of 100 g of pulp is satisfied by 13.3–32.6%. The highest content of this element was characteristic of Lel’ variety (652.4 mg/100 g).
