Abstract
Laurel leaf (Laurus nobilis L.) is a rich source of phenols, which have numerous beneficial effects on health. To maximize the yield of phenols and increase their stability and bioavailability for use in functional products, three advanced extraction techniques and two encapsulation methods were tested and optimized. Pressurized liquid extraction proved to be the most desirable method for achieving maximum yield and antioxidant activity of extracts with low energy, time, and solvent consumption. In comparison to electrostatic extrusion, spray drying resulted in higher retention of phenols and antioxidant activity. Both encapsulation methods increased the bioaccessibility of the phenols.
Abstract (croatian)
Lovorov list (Laurus nobilis L.) bogat je izvor fenolnih spoejva (fenola) koji pokazuju brojne pozitivne učinke na zdravlje. Kako bi se omogućili maksimalni prinosi fenola i povećanje njihove stabilnosti i biodostupnosti za primjenu u funkcionalnim proizvodima, ispitane su i optimirane tri napredne metode ekstrakcije te dvije metode inkapsulacije. Ubrzana ekstrakcija otapalima pri povišenom tlaku pokazala se najpoželjnijom za postizanje maksimalnog prinosa i antioksidacijske aktivnosti uz nižu potrošnju energije, vremena i otapala. U usporedbi s elektrostatskom ekstruzijom, sušenje raspršivanjem rezultiralo je većim zadržavanjem fenola i antioksidacijske aktivnosti. Obje metode inkapsulacije povećale su biodostupnost fenola.
