ABSTRACT
Lonicera caerulea L. fruits are a rich source of vitamins, organic acids, and phenolic compounds, which are characterised by their health-promoting properties. The content of bioactive compounds in this fruit may vary depending on the cultivar and the harvest date. This study analysed the effect of applying 5 ppm gaseous ozone for 1, 3, and 5 min on the chemical properties of L. kamtschatica varieties and newly created clones of L. emphyllocalyx for three years of cultivation. The fruits harvested from L. emphyllocalyx, depending on the year of harvest, had significantly larger size and weight compared to L. kamtschatica. On average, the acidity of the L. emphyllocalyx clones was 6% higher than other tested varieties. The average content of ascorbic acid was highest in L. emphyllocalyx clone '21-17'-57.80 mg·100 g-1; the year of harvest will significantly affect the content of vitamin C, reaching the highest level in 2022-53.92 mg·100 g-1. The total content of polyphenols was significantly dependent on the year of cultivation; reaching, on average, 54.8% more in 2022 compared to the rest of the years. The total antioxidant value using the FRAP, DPPH, and ABTS methods varied depending on the variety; exposure to ozone significantly increased the antioxidant value in each case. On the basis of the study, both botanical varieties can be used in food processing. Gaseous ozone exposure can significantly influence chemical composition, increasing the health-promoting value of fruit.
