Abstract
Nowadays, the loss of raw food materials as a by-product during the processing process is a big problem, and considering their usually high nutritional value, it is really a mistake not to utilize it. The worldwide distribution, availability and popularity of the consumption of oranges and orange products make the orange peel a significant dietary residue that abounds in dietary fiber and numerous bioactive components such as polyphenols and carotenoid compounds. Due to their antioxidant properties, carotenoids have been associated with numerous positive effects on human health. Regarding extraction from orange peel, the purpose of this work was to optimize the conditions of ultrasound assisted extraction of carotenoid compounds. A positive effect of extraction yield with increase in amplitude power, sonication time and sample to solvent ratio is established.
Abstract (croatian)
U današnje su vrijeme gubici prehrabenih sirovina kao nusprodukata tijekom procesa prerade i obrade veliki problem, a s obzirom na njihovu najčešće visoku nutritivnu vrijednost, zaista je šteta to ne iskoristiti. Svjetska raspostranjenost, dostupnost te popularnost konzumacije naranče i proizvoda od naranče, čine koru od naranče značajnim prehrambenim ostatkom koji obiluje prehrambenim vlaknima te brojnim bioaktivnim komponentama, kao što su polifenoli te karotenoidni spojevi. Upravo su karotenoidni spojevi zahvaljujući svojim svojstvima, između ostalog antioksidacijskim, povezani s brojnim pozitivnim učincima po ljudsko zdravlje. U pogledu njihove ekstrakcijeiz kori naranče, cilj je ovog rada bila optimizirati uvjete ultrazvučne ekstrakcije karotenoidnih spojeva. Utvrđen je pozitivan učinak povećanja amplitude, produljenja vremena ultrazvučnog tretmana te većeg početnog udjela uzorka u otapalu u svrhu većeg prinosa ekstrakcije.
