Abstract

The method was steam distillation and water and steam distillation, whereas the duration was, 4,5,6,7 and 8 hours. It was found out that the highest yield (5,85%) was obtained from 6 hours steam distillation. The analysis of the oil showed that steam distillation method gave lower acid number, but water and steam distillation for 4 hours resulted in highest cineolcontent.

Abstract

The aim of this experiment is to study the effect of harvesting age of "Pisang Ambon Jepang (Musa cavendishii Lambert) to the rate of rip g ening. The fruit age was varied from 3.5 to 4.5 months. The ripening process was induced by moisteninin dilute ethrel of 720 ppm and calcium carbide of 0.6%. The analysis was carried out soon after seven days of the ripening process. The results showed that the suitable fruit age was between 4 and 4.5 months.

Abstract

A study on the effects of distillation time and seed crushing on the yield and physico-chemical properties of cumin oil has been conducted. Two treatments were given to cumin seed i.e.(a) remain whole, and (b) crushed (using blender). The seeds were distilled using cohobation methods for 3,5 and 7 hours. The yield of whole seeds were 1.90; 2.10 and 2.23% for each distillation time, while those of crushed seeds were 2.18; 2.25 and 2.43% respectively. The evaporation residues of both oils were increased from ca. 0.18% (3 hrs. distillation) to 2.23% (7 hrs distillation). an from ca. 0.20% (3 hrs. distillation) to 0.26% (7 hrs distillation). The highest cuminaldehyde content was obtained from 3 hrs. distillation (5.99%) and the lowest was those of 7 hrs. distillation (45.14%).

Abstract

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.

Abstract

This report deals with studies on factors affecting the rates of autoxidation and hydroperoxide oxidation of vitamin A. It is shown that the latter process is much more rapid than autoxidation and the significance of this facts is assessed in relation to oxidative losses of vitamin A in Fatty foods.
