Abstract
Marelica (Prunus armeniaca L.) je vrlo važna i ljekovita biljna vrsta, a njena konzumacija je povezana sa smanjenjem rizika od kroničnih bolesti. Postupkom prešanja sjemenke koštice marelice dobivena su tri proizvoda, a to su sirovo ulje, uljni talog i pogača. U radu je ispitivan utjecaj procesnih parametara hladnog prešanja (temperatura zagrijavanja glave preše, veličina otvora glave preše) na iskorištenje ulja. Ispitivana je oksidacijska stabilnost ulja marelice, sa i bez dodanih antioksidanasa, primjenom Testa oksidacijske stabilnosti na 98 °C tijekom 15 sati. Rezultati ispitivanja prikazani su kao vrijednost peroksidnog broja tijekom 15 sati testiranja. Najveće iskorištenje ulja kod prešanja sjemenki koštica marelice dobiveno je kod procesnih parametara: nastavak za izlaz pogače 5 mm, frekvencija 25 Hz i temperatura glave preše 90 °C. Dobiveni rezultati pokazuju da veću zaštitu ulja marelice od oksidacijskog kvarenja ostvaruje dodatak ekstrakta zelenog čaja.
Abstract (english)
Apricot (Prunus armeniaca L.) is a very important medicinal plant species, and its consumption is associated with reduced risk of chronic diseases. Pressing process pitted apricots produced three products, namely crude oil, oil sludge and cake. This work examined the impact of process parameters cold pressing (temperature heating head presses, hole size head presses) to yield oil. Investigated the oxidative stability of oil apricot, with and without added antioxidants using the Stability test at 98 °C for 15 hours. The results are shown as the value of peroxide value during the 15 hours of testing. It was concluded that process parameters for the highest oil extraction during the apricot kernel pressing are as follows: cake extension length 5 mm, frekvency 25 Hz, and the press head temperature of 90 °C. The results show that greater protection of apricot oil from oxidative deterioration to supplement rosemary extract and green tea extract.
