Physical-Chemical Properties of Illipe Nut's Fat from Four Mother Trees

Il!ipenut in Indonesia still serves as one of the essentialexport commoditiesfrom thegroup of non-woodforestproducts.These nuts unfartunate!Jare traded on!J infarm of the driedfruits. Attempts are necessary to enhance the added value of illipe nuts. Among them is throughtheprocessingof thefruit intofat.One manner to extractthefatportionfromthe illipe• nutfruits is using organicsolvent. In relevant, researchn/as conducted on the extraction of illipe-nutfatfrom itsfruit of 4 species Shorea spp 1vhich tuas originatedfrom the experiment station in Bogor, WestJava. Fatextraction111as conducted using hexane as the solvent.The resultingfatuas then examinedfor itpfysical-chemicalproperties and sustained the GC• MS (Gas Chromathograpf?y-MassSpectrometry)analysis. The resultrevealed that the illipe-nutfatfrom4 tree species varied in fatyield and its pbysical-cbemical properties (i.e. moisture content, acid number,freefaticacid and iod number). The GC-MS ana!Jsisindicated that illipe-nutfat contained various saturatedfatryacid as 1vell as unsaturated and other chemical compounds, such as phenol, aldehyde, bydrocarbon (aliphaticand ryclic) and hexane (presumab!Jfromthe organicsolvent). Oleic acid is dominant chemical component of S. stenoptera and S. parvifolia, metf?yl oleate in S. pinanga and metf?ylene-(4-trimetf?ylsilanyl-pheny~-aminein S. mecisopteryx.
