ABSTRACT

Oil palm frond (OPF) juice has been known as a good source of sugars to replace commercial sugars to produce methyl 3- (3,5-di-tert-butyl-4-hydroxyphenyl) propionate. The aim of this study was to investigate the effect of temperature (°C), initial pH medium, agitation speed (rpm) and concentration of glucose (g/L) on the production of methyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate from OPF juice by using Ceratocystis fimbriata (C. fimbriata). The design of experiment (DOE) method was used to screen the best parameters affecting the production of methyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate. The Gas Chromatography-Mass Spectroscopy (GC-MS) with Solid Phase Micro Extraction (SPME) was used to analyze and separate the peak of methyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate. Based on the GC-MS analysis, results showed that the most favorable condition for methyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate production was achieved at an initial pH medium (8), agitation speed (100 rpm), temperature (25°C) and 30 g/L of glucose in OPF juice. Methyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate were produced when the retention time was 32.80 min, the relative peak area was 0.24 % of chromatogram area. This result showed the great potential usage of OPF juice as a substrate to produce methyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate by C. fimbriata.

Key words: Oil palm frond juice, Methyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate, Ceratocystis fimbriata.
