Abstract	Brojna istraživanja pokazala su da su plodovi jagoda bogati fenolnim spojevima te imaju antioksidativno i antiproliferativno djelovanje. Cilj ovog istraživanja bio je utvrditi kako ekološki prihvatljivi tretmani otopinom salicilne kiseline, otopinom koloidnog srebra i ozonom utječu na antioksidativnu aktivnost plodova jagoda (Fragaria x ananassa Duch.) sorte Albion tijekom 7 dana skladištenja na 4C. Koncentracija askorbinske kiseline, fenolnih spojeva te ukupna antioksidativna aktivnost u plodovima jagoda određeni su spektrofotometrijski. U plodovima jagoda tretiranim otopinom salicilne kiseline, otopinom koloidnog srebra i ozonom, ukupna koncentracija askorbinske kiseline i antioksidativna aktivnost bili su veći nego u kontrolnim plodovima, što pokazuje da ovi tretmani povoljno djeluju na očuvanje kvalitete i nutritivne vrijednosti plodova jagoda tijekom skladištenja. Tretman otopinom salicilne kiseline ima najbolji učinak, jer je rezultirao značajnim porastom koncentracije askorbinske kiseline, fenola i ukupne antioksidativne aktivnosti u plodovima jagoda.
Abstract (english)	Numerous studies have shown that strawberries are rich in phenolic compounds, and have antioxidant and antiproliferative activities. The aim of this study was to determine how environmentally friendly postharvest treatments with salicylic acid solution, colloidal silver solution and ozone, affect the antioxidant activity of strawberry fruits (Fragaria x ananassa Duch. cv. Albion) during 7 days of storage at 4 C. The content of ascorbic acid, total phenols and antioxidant activity of strawberry fruits were determined spectrophotometrically. In strawberry fruits treated with salicylic acid solution, colloidal silver solution and ozone, the total content of ascorbic acid and antioxidant activity value were higher than in control fruits, which indicates that these treatments are useful for preserving fruit quality and nutritional value during storage. The treatment with salicylic acid solution has the best effect, because during storage, there was a significant increase in the content of ascorbic acid, phenols and antioxidant activity.
