Abstract

Dryobalanops aromatica is a woody plant that produces non timber forest product such oil and crystal. Thechemical composition information is important for oil utilization and specific marker of the material. Traditionally, oilquality was grouped based on its colour. The whiter the colour, the better the quality. This paper examines the chemicalcontent of four oil groups and two kinds of crystal. The examination was carried out in Gas Chromatography MassSpectrometry (GCMS). The results show that the oil of Dryobalanops aromatica 1 contains borneol up to 26.02%, D. aromatica 2 contains 13.95%, D. aromatica 3 contains 24.03%, and D. aromatica 4 contains 1.09% in longiborneol form. Meanwhile, crystal 1 contains 92.70% of borneol and crystal 2 contains 90.73%. Borneol compoundcan act as chemical marker of Dryobalanops aromatica.

Abstract

Indonesian Illipe nuts or known as ‘Tengkawang’ is one of essential export commodities from the non-wood forest products group. Unfortunately such traded commodityis still in originalshapeor unprocessed fruits in dry condition, thereby imparting only small-added values. One way to enhance their traded values is by processing the fruits into so-called illipe nut's fat. Currently, the illipe nut’s process is through the extraction of the respective fruits (nuts) using organic solvents. Different kinds of organic solvent could presumably affect the qualities of the resulting-fat. This paper studies the illipe nut’s extraction using two solvents: benzene and hexane. The resulting fat was then examined for it's qualities, i.e. yield, physico-chemical properties and chemical component content analysis using GC-MS (gas chromatography-mass spectrometry) pyrolysis. Results revealed that the hexane produces greator yield of storage time. The illipe nut's fat lower acid value, free fatic acid (FFA) content and lower iod number than those of benzene. Low acid value, FFA, and the iod number creates the fat which is more resistant against hydrolytic and oxidative rancidity, and longer storage time. GC-MS analysis indicated that the chemical components in the benzene-extracted illipe nut's fat was dominated by methyl-octadec-9- oneate, while those in hexane-extracted fat by methyl oleate (compound with saturated C-C bonds).Judging from the overall results, it seems the use of hexane is more prospective as solvent toextract the fat fromillipe nuts than benzene.

Abstract

Illipe nut in Indonesia serves as one of the essential export commodities from non-wood forest products group. Illipe nut through the extraction can be processed into high-economic valued fat that could function as cocoa butter substitute (CBS), obtained through extraction of illipe nut Illipe nut's fat that results from extraction process can not be directly used, but should be previously refined. In this study, refining of illipe nut's fat was conducted through degumming and neutralization process. Degumming process was carried out by adding acids (acetic, citric and phosphoric) each with 20% strength at 0,4% (w/w) to the fat that has been previously heated. The results showed that degumming using phosphoric acid produced a better quality fat compared to that with citric acid and acetic acid. NaOH was used for neutralization process. The resulting neutralized fat was then examined for its physical-chemical properties which revealed that such properties were not so far different from those of commercial illipe nut's fat. The GC analysis as conducted on the refined illipe nut's fat showed that it consisted of various saturated fatty acid as well as unsaturated and other chemical compounds. All of the examined illipe nut's fat in this research showed that oleic acid is the dominant component.

Abstract

Mata kucing dammar has long become remarkable export commodity, most of which unfortunately is still in naturalform (chunk-shapped exudates) obtained from the tapping of its host trees (Shorea javanica). Accordingly, such dammarstill contains large amount of impurities thereby lowering its qualities or trade values. Consequently, this necessitates athorough purification attempt to enhance the dammar's added-value. The dammar purification prevalently uses organicsolvent. However, the market demand for the solvent-free dammar products currently tends to increase commensurate withthe advancement in dammar usage for drugs/ medicine and food industries. In relevant, purification of mata-kucingdammar was experimented using manual heating system, rather than organic solvent. Result revealed physico-chemicalproperties of the heat-purified dammar were not significantly different from those of natural dammar (without purificationtreatment) as well as of the solvent-purified dammar. Even, with respect to ash content (impurities) and toluene insolubility,the heat-purified dammar seemed to be better than the natural dammar. GC-MS analysis revealed there were five majorchemical compounds with relatively large contents in heat-purified dammar. Such phenomena were similar to those in thenatural dammar, with the contents of those compounds in the heat-purified dammar slightly higher.
