Penentuan Kadar Minyak dan Kadar Air Pada Palm Kernel Expeller (PKE) dan Copra Expeller (Copex)

Abstract

The determination of oil content and moisture in Palm Kernel Expeller (PKE) and Copra Expeller (COPEX) at Palmcoco Laboratories. Had been done the determination of oil content with soxhlet method for 4 hours and the determination of moisture with heating method at 105o C temperature and gotten result the determination of oil content in PKE and COPEX were 7,44 % and 6,20 %, while the determination of moisture in PKE and COPEX were 6,45 % and 9,07 %. The determination of oil qualities, one of it’s parameters was the determination free fatty acid. After that, determinied the free fatty acid of PKE and COPEX with based-acid titration method, getting the result of free fatty acid in PKE and COPEX were 4,23 % and 7,17 %. From the determination of free fatty acid was gotten that PKE still fulfilled the specification of Indonesia National Standard (SNI) while COPEX didn`t fulfill specification of Indonesia National Standard (SNI), while the maximum of free fatty acid content of Indonesia National Standard (SNI) number 01-2901-2006 was 5 %.
