Abstract

Penelitian ini menyelidiki pengaruh penambahan BHA (butil hidroksi anisol) terhadap ketengikan minyak sawit akibat fotooksidasi. Oksigen singlet dihasilkan dari reaksi fotokimia tak langsung menggunakan reaktor flat bed pada konsentrasi Rose Bengal 400 ppm dan laju alir oksigen 5 L/menit. Keberadaan BHA dengan konsentrasi 200 ppm mampu menjaga nilai bilangan peroksida minyak sawit RBD di bawah 2 mek/kg selama 210 menit oksidasi oleh oksigen singlet. Sebaliknya minyak sawit RBD tanpa BHA sudah mencapai nilai 2 mek/kg dalam waktu 20 menit.

The effect of BHA (butylated hydroxyanisole) addition to palm oil rancidity caused by photooxidation has been investigated. Singlet oxygen was produced by indirect photochemical reaction using flat bed reactor at 400 ppm of Rose Bengal and 5 L/min of oxygen flowrate. The existence of 200 ppm BHA in RBD palm oil retained the peroxide value of the oil below 2 meq/kg for 210 minutes under singlet oxygen oxidation. In the other hand those without BHA reached 2 meq/kg only after 20 minutes.
