(The preparation of monoglyceride from coconut oil as emulsifier) Endah Djubaedah; Achmad Moestafa; Mariana -
Warta Industri Hasil Pertanian Vol 12, No 1-2 (1995)
Publisher : Balai Besar Industri Agro

Food emulsifier is an important addive used in food industries.Emulsifiers are usedto improve the texture of products such as to stabilize margarine,ice cream,etc.Basically emulsifier consist of two functional groups, the first one dissolves in water and the other in oil which enebles them to bridge two unmixed phases.The most widely used emulsifiers are monoglyceride which contain long alkyl chain residue from fatty acid chain and hydroxyl groups from glycerol.Monoglycerida had been prepared in this study through the reaction of coconut oil and glycerol using coustic soda as catalyst.The best treatment was obtained from the reaction of one parts of coconut oil and four parts of glycerol at 250 degree C, stirred for 3 hours using of 0.20% NaOH as catalyst which produced 45% yield containing 77% monoglyceride.

(The Effect of Time Duration and The Rate of Distillation on Oil Yield and Vetiverol Content in Vetiver Root). Achmad Moestafa; Priyo Waspodo; Syaeful Hakim

Vetiver oil is one of the essential oils which are use as perfumeand fragrance material.It has a pleasant odour and a typical charateristic as a fixative agent in perfumes.An oil which has high vetiverol content is usually more appreciated and highly valued.An attempt to perform and high vetivero content from vetiver root by manipulating the time and rate of distillation has been carried out.It was observed that the longer the distillation was proceeded a higher yield of oil and vetiverol content was discovered.Rate of distillation seemed to have he same effect,the faster distillation was taken place, more oil and higher vetiverol was found.

(The Isolation of Citronelle Oil Components by Fractional Distillation on Kilo Scale) Achmad Moestafa
Warta Industri Hasil Pertanian Vol 7, No 01 (1990)

Citronellal, citronellol and geraniol are then main components of citronella oil. They can be isolated by chemical means or fractional distillation. This study employed the second method. A perforated plate colomn, bubble cup type was used and the operation was carried out on 1:3 reflux ratio. The result showed that citronella was distilled as the first and second fraction after 85 min. The third fraction was a mixture of all components.It took 60 min. to produce 300 ml of liquid; the boiling range was 84-87 C and the separation was poor. It can be said that other than boiling point, the time of distillation should also be managed carefully. The separation depend on the time of distillation and the value of reflux ratio.

(The Effect of Temperature and Duration of Freezing Process on The Isolation of Anethole From Star Anise (Illicium verum) Achmad Moestafa; Chairul -; Agus Arifin
Warta Industri Hasil Pertanian Vol 14, No 1-2 (1997)
Publisher : Balai Besar Industri Agro

Anethol that is used in flavor, fragrance and medicine is the main component of anise oil. Pure antehol has melting point around 21.6 to 22 derajat celcius that is close to room temperature. An attempt to isolate anethole from Star anise oil (Illicum verum) a studied through freezing process has been done. It was found when the oil was cooled to 12 derajat celcius almost all the oil was solidified. The crystal contains 89% anethole that is not pore enough. When the oil was cooled at 14 derajat and 16 derajat celcius, 30% and 7% of the oil was crystallized respectively and contained 90% and 94% anethole. The experiment showed the lower the temperature, the least pure anethole was collected. A technique to isolate anethole from star anise oil can be done by fractional crystallization.
