Good nutrition is impossible without vegetables, which are the richest source of natural antioxidants, biologically active substances. One of the sources of which is onion. The aim of our work was to study the change in basic chemicals and the natural mass loss in onions, depending on the bulb size and storage time. As a result of the research, it was revealed that on the day of the experiment, the highest content of dry substances, the amount of sugars and ascorbic acid was in the bulbs with the largest transverse diameter of more than 6.0 cm and was 20.1%, 13.6% and 15.9 mg% , it is 1.2, 2.0 and 1.7 times higher than that of bulbs with a diameter of 3.0-4.0 cm. When storing for up to 30 days, the accumulation of basic chemicals occurred, further storage for 90 days led to an insignificant decrease in them but it was higher than when it was put in storage. The highest natural mass loss was observed in the bulbs with the largest transverse diameter of 3.0-4.0 cm and ranged from 8.3% to 12.4%, depending on the retention period. Bulbs with the largest transverse diameter of more than 6.0 cm lost mass in the range of 6.2-9.7%.
