Abstract
U ovom je radu ispitan utjecaj veličine plodova (<15 g, 15-30 g, >30 g) jagode sorte 'Albion' na bioaktivni sastav i antioksidacijski potencijal u svježim plodovima i 3D ispisanim proizvodima. U svim uzorcima su spektrofotometrijko određene koncentracije ukupnih fenola, flavonoida, flavanola, hidroksicimetnih kiselina, kondenziranih tanina i monomernih antocijana, te antioksidacijski potencijal DPPH i FRAP metodama. Različite mase plodova značajno utječu na udio bioaktivnih spojeva pri čemu svježi plodovi manje mase (<15 g) imaju najveći udio ukupnih fenola i antocijana. Slično, 3D ispisani proizvodi od plodova mase <15 g su imali veće udjele ukupnih fenola, flavonoida te antocijana u odnosu na 3D proizvode proizvedene od plodova većih masa. Ipak, antioksidacijski kapacitet određen DPPH i FRAP metodama nije se razlikovao u ovisnosti od mase plodova ni u svježim, kao ni u 3D ispisanim proizvodima. U zaključku, dobiveni rezultati ukazuju na važnost veličine plodova u proizvodnji 3D funkcionalnih proizvoda na bazi jagode.
Abstract (english)
In this study, the influence of fruit size (< 15 g, 15-30 g, > 30 g) of the strawberry cultivar 'Albion' on the bioactive composition and antioxidant potential of fresh fruit and 3D printed products (3DP) was investigated. The concentrations of total phenols, flavonoids, flavanols, hydroxycinnamic acids, condensed tannins and monomeric anthocyanins, and antioxidant potential (DPPH, FRAP) were determined spectrophotometrically. Fresh fruit with a lower weight (< 15 g) had the highest proportion of total phenols and anthocyanins. Similarly, 3DP made from fruit weighing < 15 g had higher levels of total phenolics, flavonoids and anthocyanins than 3DP made from higher mass fruit. However, the antioxidant capacity determined by the DPPH and FRAP methods did not differ between fresh and 3DP as a function of fruit weight. In summary, the results obtained indicate the importance of fruit size in the production of functional strawberry-based 3DP.
