Jenis dan Konsentrasi Tanah Pengelantang untuk Menurunkan Prekursor Senyawa 3-MCPDE dan GE pada Pemucatan CPO

Refined palm oil contains contaminants such as 3-monochloropropane diol ester (3-MCPDE) and glycidyl (GE) which are formed from diacylglycerol (DAG) chloride (Cl) precursors during processing. There is a need to control the levels of especially bleaching stage using selected earth (BE). Reducing number after will minimize formation 3-MCPDE GE in bleached (BPO) for next refinery stage. The research consisted three stages: (1) characterization raw materials consisting CPO, BE types 1, 2, 3, 4, 5; (2) study on effect type; (3) concentration reducing DAG Cl by chemical analysis quality. results showed that degummed (DPO) contained 6.70%, free fatty acid 5.66%, carotene 424.31 mg/kg, P 20.30 Fe <0.021 mg/kg. five have different physicochemical properties be seen BPO. second BE-4 was most potential BE. Using 2.5% proven reduce total resulted BPO sample. level decreased 3.05 mg/kg with largest decrease percentage 55.80% compared DPO has been able withstand prevent increase precursor process.
