Abstract

Enzimska interesterifikacija koristi se za obradu ulja i masti radi dobivanja restrukturiranih lipida sa željenim tehnološkim svojstvima. Međutim, s obzirom na to da sirovi materijali sadržavaju velike udjele bioaktivnih tvari, još uvijek je nejasan utjecaj ovakvih enzimskih procesa na biološku aktivnost konačnog produkta. Stoga je svrha ovog istraživanja bila procijeniti antioksidacijski potencijal i modulacijski učinak dvaju sirovih materijala iz područja Amazone (buriti ulja i murumuru masti) na stanice jetre (HepG2), i to prije i nakon procesa interesterifikacije. Istraživanje je pokazalo da su neke bioaktivne komponente sirovih materijala i njihov antioksidacijski učinak očuvani nakon enzimske esterifikacije restrukturiranih lipida, pri čemu dolazi do modulacije HepG2 endogenog antioksidacijskog enzima.<br />Enzymatic interesterification is used to manipulate oil and fat in order to obtain improved restructured lipids with desired technological properties. However, with raw materials containing significant amounts of bioactive compounds, the influence of this enzymatic process on the bioactivity of the final product is still not clear. Thus, the aim of this study is to evaluate the antioxidant potential and modulatory effects of two raw materials from the Amazonian area, buriti oil and murumuru fat, before and after lipase interesterification, on human hepatoma cells (HepG2). The results indicate that minor bioactive compounds naturally found in the raw materials and their antioxidant capacity are preserved after enzymatic interesterification, and that the restructured lipids modulate HepG2 endogenous antioxidant enzyme.
