Perubahan Mutu Minyak Kelapa dan Minyak Sawit Selama Penggorengan

Abstract: <p>Abstrak</p><p>Proses penggorengan akan menyebabkan perubahan mutu minyak akibat reaksi hidrolisis, oksidasi dan proses termal. Penelitian ini bertujuan untuk mengetahui perubahan mutu  minyak kelapa dan minyak sawit selama penggorengan. Minyak kelapa dan minyak sawit masing-masing digunakan untuk menggoreng kentang pada suhu 170°C selama 15 menit. Minyak tersebut digunakan untuk 3 kali penggorengan. Pada akhir penggorengan dilakukan pengambilan sampel minyak untuk dievaluasi kadar air, kad… Show more

“…Minyak kelapa memiliki kestabilan yang tinggi terhadap reaksi oksidasi dibandingkan minyak sawit sebagai minyak goreng selama penggorengan berulang (Karouw dan Indrawanto, 2015). Sementara itu, Fernández-Cedih et al (2012) melaporkan bahwa fraksi olein minyak sawit lebih stabil daripada minyak kedelai selama penggorengan.…”

“…Fat hydrolysis occurs because of the reaction between fat and water dissolved in fat under appropriate conditions of temperature and pressure, besides that it is also triggered in the presence of catalysts such as acids, bases and enzymes (lipase). However, the cause of damage to fat or oil is largely the result of oxidation reactions when compared to hydrolysis reactions (Rukmini & Raharjo 2010;Karouw & Indrawanto 2015). According to Derlean (2009) the oxidation speed of fats/oils is influenced, among others, by high temperatures, humidity and sunlight.…”

“…The extraction treatment at 90 °C and 3 hours produced fat/oil with the lowest peroxide number of 2.74 ml.eq/kg, and the highest was obtained in the extraction treatment at 80 °C and 1 hour for 54.48 ml.eq/kg . Decreasing the number of peroxides at higher extraction temperatures is due to the decomposition of hydroperoxide during the heating process into secondary oxidation products that are unstable (Karouw & Indrawanto, 2015). If the decomposition rate of hydroperoxide is higher than the rate of formation of hydroperoxide in fat/oil, as a result the peroxide number becomes lower (Rukmini & Raharjo, 2010).…”
