Abstract
Mikrozelenje je nezrelo zeleno povrće, koje se ističe radi jednostavnog uzgoja te povećanog sadržaja bioaktivnih tvari u odnosu na zrelo povrće. Na kvalitetu mikrozelenja nakon skladištenja utječu različiti abiotički čimbenici, od kojih je najvažniji temperatura zbog reguliranja funkcionalnih metaboličkih procesa. Istraživanje je provedeno na dva kultivara rotkvica (Raphanus sativus L): daikon i crvena rotkvica, uzgajanih sedam dana u komorama s ljubičastim i bijelim LED osvjetljenjem. Cilj rada bio je ispitati utjecaj 14-dnevnog skladištenja pri niskoj temperaturi (+4°C) na antioksidacijsku aktivnost mikrozelenja rotkvica mjerenjem antioksidativne aktivnosti, sadržaja polifenola, askorbinske kiseline, pigmenata, antocijana te produkata lipidne peroksidacije. Rezultati su pokazali da je 14-dnevno skladištenje na niskoj temperaturi dovelo do inhibicije većine metaboličkih putova, što dokazuju stabilna antioksidativna aktivnost, nepromijenjena količina ukupnih polifenola. Niska temperatura potaknula je i biosintezu antocijana prevenirajući oksidativni stres kultivara crvene rotkvice, što ukazuje na stabilnije fiziološke reakcije u odnosu na kultivar daikon.
Abstract (english)
Microgreens are immature green vegetables, which stand out due to their simple cultivation and increased content of bioactive substances compared to mature vegetables. The quality of microgreens after storage is affected by various abiotic factors, such as temperature due to the regulation of functional metabolic processes. This investigation was conducted on two cultivars of radish (Raphanus sativus L): daikon and red radish, grown for seven days in chambers with purple and white LED lighting. The aim of the study was to examine the influence of 14-day storage at low temperature (+4°C) on the antioxidant activity of two cultivars of radish microgreens by measuring the antioxidant activity, content of polyphenols, ascorbic acid, pigments, anthocyanins and lipid peroxidation products. The results show that 14-day storage at low temperature led to inhibition of most metabolic pathways what led to stable antioxidant activity and unchanged content of polyphenols. Low temperature also triggered anthocyanin biosynthesis, preventing oxidative stress in the red radish cultivar, which indicates more stable physiological reactions compared to the daikon cultivar.
