Abstract

ABSTRACTGugule, S. and F. Fatimah. 2010. Characterization of spices virgin coconut oilA study has been carried out to find out the effect of some spices type on quality and characteristic of fatty acid of virgin coconut oil (VCO). The test of spice VCO quality conducted with the determination of iodine and acid number, water content and peroxide number. The profile of fatty acid of VCO was tested with the liquid gas chromatography, using the internal standard of margaric acid. The experimental result showed that control and spice VCO that is VCO nutmeg, leaf of salam, sweet basil and galingale have the quality fulfilling standard APCC, except number iodine. As compared to control, the addition of spice at making VCO nor have an effect to fatty acid percentage in VCO, but having an effect to reduction fatty acid content in VCO (calculated in mg / 100g sample)..Kata kunci : Characterization, virgin coconut oil, spices

Abstract

The studies have been done about the transformation of safrole into isosafrole. The transformation wasdone using reagents, namely t-BuOK/DMSO and KOH/CH2OHCH2OH. The purities of all products weretested with thin layer and gas chromatography. Thereafter the structures were identified with infraredspectrophotometers, NMR1H and 13C spectrometry, and mass spectrometry. The isomerization product ofsafrole into isosafrole with highest percentage yield (97%) was given t-BuOK/DMSO.

Abstract

This research was done to study benzo(a)pirene content produced from liquid smoke by directburning process, also how to reduced the component. The results show that liquid smoke from coconutpericarb that produced by direct burning method has 28% recovery. The smoke was yellow to brown,smelled as smoke with density 0,9965 g/mL. To reduce benzo (a) pirene of liquid smoke was done usingredistilled and absorbed with active carbon. Redistilled liquid smoke was done at 98-100 oC. RedistilledLiquid smoke almost colorless and no color compared with initial liquid smoke, less smoke scent. Thedensity was 0,9970 g/mL with 55% recovery from initial smoke. Absorbed liquid smoke using activecarbon (1:5) was acquired more clear liquid, no color and no scent, density 0,9975 g/mL with 51,7%recovery. Benzo(a)pirene concentration can be reduced using redistilled and absorbed with activecarbon method. Reduce concentration using redistilled technique was 33.1%, whereas using absorbedtechnique was 54,3%.
