Abstract
Mandarina je voće bogato bioaktivnim komponentama. Neprikladno rukovanje i skladištenje nakon berbe nepovoljno utječu na razine bioaktivnih spojeva. Jestivi omotači imaju značajnu ulogu u smanjenju gubitaka poslije berbe. Cilj ovog istraživanja je ispitati utjecaj triju vrsta jestivih omotača na razine bioaktivnih komponenata u plodu mandarina sorte 'Chahara' iz doline Neretve tijekom tri tjedna njihova skladištenja. Plodovi su tretirani postupkom potapanja u vodene otopine: kitozan (2% w/v), zein (2% w/v) te kombinacijom „sloj po sloj“ obje vrste omotača, uz kontrolu (netretirani plodovi). Na tretiranim mandarinama tijekom tri tjedna skladištenja na 5 °C mjereni su: gubitak mase ploda, udio ukupnih flavonoida, udio ukupnih fenola, askorbinska kiselina, topljiva suha tvar i ukupna kiselost. Plodovi tretirani kombinacijom kitozana i zeina pokazali su najveću srednju vrijednost sadržaja ukupnih polifenola, flavonoida te askorbinske kiseline tijekom skladištenja. Plodovi mandarina tretirani zeinom pokazali su najveći gubitak mase tijekom skladištenja.
Abstract (english)
Mandarin fruit is rich in bioactive components. Improper handling and storage after harvest adversely affects the levels of bioactive compounds. Edible coatings play a significant role in reducing post-harvest losses. The aim of this research is to examine the influence of three types of edible coatings on the levels of bioactive components in mandarin fruit of the ‘Chahara’ variety from the Neretva Valley during three weeks of their storage. The fruit was treated by immersion in aqueous solutions: chitosan (2% w/v), zein (2% w/v) and a combination of both types of coating "layer by layer", with a control (untreated fruits). To determine the influence of edible coatings on bioactive components, the following were measured during three weeks of storage at 5 °C: total flavonoids, total phenols, ascorbic acid, total soluble solids and titratable acid. Fruits treated with a combination of chitosan and zein showed the highest mean content of total polyphenols, flavonoids and ascorbic acid during storage. Fruits treated with zein showed the highest weight loss during storage.
