Abstract

Jagode su popularno voće čija proizvodnja u svijetu kontinuirano raste. Poznate su po atraktivnom izgledu plodova te ugodnoj aromi i okusu. Sve više istraživanja dokazuje pozitivan učinak konzumacije jagoda na ljudsko zdravlje. Kemijski sastav plodova je zasigurno odgovoran za takav pozitivan učinak. Međutim, kod jagoda koje su zastupljene na tržištu se uglavnom obraća pozornost na veličinu, boju i vanjski oblik plodova, a puno manje na kemijski sastav. Zbog toga je cilj ovog rada bio analizirati plodove šumske jagode i vrtne jagode kako bi se utvrdila razlika u kemijskom sastavu između njih. Za analizu su korišteni plodovi vrtne jagode (Fragaria x ananassa) sorte 'Sonata' i plodovi triju različitih populacija šumske jagode (Fragaria vesca). Analizirani su na količinu ukupne topljive suhe tvari (TST), ukupnu kiselost (UK), omjer TST/UK, koncentraciju ukupnih flavonoida, ukupnih fenola i ukupnih antocijana. Utvrđeno je da su količina ukupne TST, koncentracija ukupnih flavonoida i ukupnih fenola veći u plodovima šumske jagode. Ukupna kiselost je bila podjednaka u plodovima obje vrste. Jedino je koncentracija ukupnih antocijana bila veća u plodovima vrtne jagode.

Abstract (english)

Strawberries are a popular fruit their production is continuously increasing. Strawberries are well known for their attractive appearance, and also for their pleasant aroma and taste. An ever-increasing number of research papers is confirming the positive influence of strawberry consumption on human health. The chemical composition of strawberry fruit is probably responsible for this. However, with strawberries currently present on the market, most attention is given to the size, shape and color of the fruits, while a lot less attention is given to their chemical composition. Therefore, the goal of this research was to analyze the fruits of woodland strawberry and garden strawberry and determine the difference between their chemical composition. The fruits of garden strawberry (Fragaria x ananassa), cultivar 'Sonata' and three different populations of woodland strawberry (Fragaria vesca) were used in this analysis. The fruits were analyzed for total soluble solids content, total acidity, concentration of total flavonoids, total phenols, and total anthocyanins. It was determined that the fruits of woodland strawberry had a higher amount of total soluble solids content, higher concentration of total flavonoids and higher concentration of total phenols. Total acidity was approximately the same for all fruits. Only the concentration of total anthocyanins was higher in the fruits of garden strawberry.
