Abstract
U radu je ispitivan utjecaj temperature ekstrakcije (40 – 50 °C), tlaka ekstrakcije (100 – 300 bar) i vremena ekstrakcije (2 – 4 h) kao i njihove interakcije na ekstraktibilnost ulja iz usitnjenog zrna soje sorte „Ika“, srednjeg promjera čestica 0,3131±0,01 mm, pomoću superkritičnog CO2. Volumni protok superkritičnog CO2, za provedeni opseg istraživanja, bio je konstantan i iznosio je 1,629 L/min. Metodom odzivnih površina, pomoću Box-Behnken-ovog dizajna, određeni su optimalni uvjeti ekstrakcije (temperatura: 50 °C, tlak: 300 bara i vrijeme: 4 h); za istraživani raspon eksperimentalnih podataka, pri kojima je modelom predviđen maksimalni prinos ulja od 6,55 g ulja/100 g usitnjenog zrna soje. Analiza varijance pokazala je da postoji značajan utjecaj tlaka i vremena ekstrakcije, kao i njihove interakcije, na prinos ulja. Temperatura ekstrakcije nije značajno utjecala na prinos ulja, niti promatrana kao pojedinačan parametar, niti prilikom interakcije s drugim ispitivanim parametrima. Za opisivanje kinetike superkritične CO2 ekstrakcije ulja iz zrna soje uspješno je korišten jednofazni difuzijski model koji je pokazao dobra slaganja s eksperimentalnim podacima.
Abstract (english)
The effects of temperature (40 – 50 °C), pressure (100 – 300 bar) and extraction time (2 – 4 h) and their interactions on the extractability of oil from milled soybeans variety „Ika“ mean particles size diameter 0.3131±0.01 mm using supercritical CO2 were studied. Volumetric solvent flow rate was kept constant at 1.629 L/min. The optimal conditions for the extraction of oil (temperature: 50 °C, pressure: 300 bar and time: 4 h) were determined by response surface methodology using the Box-Behnken design. At the above menitioned conditions, maximum oil yield was 6.55 g oil/100 g milled soybeans. The analysis of variance showed that the effect of pressure and extraction time, as well as their interaction, on the oil yield was significant. Extraction temperature had no significant effect on the oil yield, nor as a single parameter, nor in interaction with other examined parameters. One stage diffusion model has been successfully used to describe the supercritical CO2 extraction kinetics of oil from soybeans. The experimental values agreed well with those predicted by diffusion model.
