Recommended method for the determination of potassium using the Air-Acetylene Flame AAS technique requires an addition of cesium cation which is expensive (dua to a scarcity of supply in Indonesia) to suppress ionization suppressant is investigaed and compared with that of cesium cation.The results of investigation conclude that only sodium cation is capable to substitute cesium cation in the method.

(Essential Oil from The Twigs and Leaves of Sappuko (Leptospermum flavescens Smith) and Its Distillation Technique) Salya Sait; Enny Hawani Lubis
Warta Industri Hasil Pertanian Vol 7, No 01 (1990)
Publisher : Balai Besar Industri Agro

The essential oil of Leptospermum flavescens leaves and twigs has been studied. The distillation techniques used were water distillation and water and steam distillation in order to determine the most suitable technique. The essential oil of the twigs and leaves are of the same type. Linalyl acetate, beta-terpineol, terpineol-4 and borneol are the major constituents of the oils and present in different quantities. The high content of linalyl acetate (34.44%) showed that the oil could become a new source of linalyl acetate. The result of the two distillation technique showed the significant difference in the leaves

To increase the costumer acceptance and provide a safeguard of the animal-based snacks customers against the consumption of excessive cholesterol, the quantitative data on the level of cholesterol content of some animal-based sancks produced in west java,i.e. chips of sliced fried chiken small intestine,floured fried eel and cow lung :seasoned dried eel and side-dish of GLC analysis using pracedures for both the formation of acetate derivatives and those of TMS derivatives. Meanwhile,the moistures content as wes as the total fast were also determined.The result of analysis indicated that the highest content of cholesterol was about 3,26. Where as the lowest was about 0.009 grams/100 grams of the food sample, while the level cholesterol content did not depend on the levels of total fast contents.

To obtain the good quality of International Market Standard and better oil as raw material for rose oil synthetic where as the price of natural rose oil is much higher in price that of synthetic. The fractional distillation process was employed on crude Java Citronella oil grown in Sukabumi and Purwokerto to obtained the oil with international market quality and the oil fraction was used as basic material for rose oil synthesis. It was concluded that due to a high cost of the fractional distillation, it was unable to raise the economic added value of crude oil via quality improvement using this process except when the oil fraction was used as basic material for rose oil synthesis.

(Essential Oil from the Leaves and Steams of The red Ginger Plant A Rich Source Of Linally Acetate) Salya Sait; Enny Hawani Loebis
Warta Industri Hasil Pertanian Vol 6, No 02 (1989)
Publisher : Balai Besar Industri Agro

The chemical constituents of an essential oil obtained from the leaves and stems of the plant Zingiber officinale Roscoe of a red type, have been studied using gas -liquid chromatography. The oil contains linalyl acetate (37.9%) as the major component. Some other abundant constituents were also identified which are geranial (9.35%), neryl acetate (6.23%), terpenyl acetate (5.66%), and one which is still unidentified (6.78%). The high content of linalyl acetate showed that the oil, which is comparable to that of bergamot oil, be a valuable commodity and affirms that another type of essential oil has been recognized.

(Flavour Fixation of Shallot and Soup Leek) Salya Sait; Enny Hawani Lubis

The flavours of shallot (Allium cepa linn)and soup leek (A.fistulosum.linn)were separated from their natural sources using solvent extraction technique as wellas juice expression.In the forms of viscous extract liquid and juice concentrate, the flavours were than fixed using the fixation formula US patent 3,619,212; November 9,1971.The stability of aroma and the resistance to microorganisms during storage, and the aroma preference of all fixatives produced were also studied.The result showed that relatively the best stability of aroma was proccessed by the fixatives derived from the extract obtained via the solvent extraction using ethanol 1:1 the resistance to microorganisms of all fixatives was excellent,and the result of sensory eavaluation indicated that the aroma of fixatives derived from the juice concentrate were prefered over thosefrom the ethanol extract.

(Improving Clove Leaf Oil Quality For Export Using Chemical Deterpenation Process). Salya Sait; Tiurlan Farida Hutajulu

In order to improve the export quality of the Indonesian cloveleaf oil,the 66% eugenol containing essential oil produced by the water and steam distillation of old the ground clove leaves (Syzigium aromaticum L.)was deterpenated using two chemical methods of the deterpenation process,i.e. the method based on the formation of water-soluble alkali-phenolates to separate the water-insoluble non-phenolic constituents from the oil and that based on the extration of the soluble oxygenated constituent in dilute ethanol to separate the insoluble terpenes from the oil.Results of the experiments concluded that the method of deterpenation involving the formation of alkali phenolates was comparatively the most favourable process for carring out the quality upgrading of clove leaf oil, since it gave the terpeneless prodict with the highest content of eugenol (92%, compared to 72%obtained from the extration method).However, the method gave the terpene extract, as by-product,on the contrary,with the lowest content of betacaryophyllene (75%,compared to 80% obtained from the other method).

(Syntesis of rose oil from the terpeneles java citronella oil) Salya Sait; Enny Hawani Lubis

In order to diversify the end-use and raise the commercial value of java citronella oil,two G-types of the oil obtained from the steam distillation of G-3 and G-mixture of the Mahapengiri (Cymbopogon winterianus Jowitt)leaves, were deterpenated by the method of selective extration of the soluble oxygebated constituents in dilute alcohol as well as the method of chromatography using alumina as the absorbant,nonpolar ofganic (hexane)and polar one (ethyl acetate).To complete the preparation of the basic material for the synthesis of rose oil,the terpeneles products were then mixed with the calculated volumes of phenethyl alcohol comparable to that of the Turkish rose oil,instead to that of the commercial Bulgarian which had been analyzed in the experimental.The result of the experiments concluded that the terpeneless oils obtained from the deterpenation method of selective extration were the most favourable for the preparation of the basic material for the synthesis of rose oil,since the ratios of the citronella/geraniol contents were between one and two respectively.

In search for the aroma industrial utilization of indonesia essential oils of non-exported commodities,yhe main chemical constituents of essential oils originated from the plant species of some cinnamomum,e.g. c.javanicum, c.camphora and c sintok,also foeniculum vulgare,hyptis suaveolens and ocimum canum,which are all grown likely in indonesia,were surveyed by literature.Based on criterion that the amount of each constituents present inthe oil must exceed 10%, enantiomerically pure and harmless to man.it was found found that the cinnamomum species be likely the sources of safrole,whereas only foeniculum vulgare be likrly the source of fenchone.
