Abstract

The study of additional effect of butylated hydroxy toluene (BHT)on extraction quality of crude,degummed,and bleached castor oil has been conducted.This study was aimed at elaborating the effect of BHT addition on every castor oil processing step e.g crude oil extraction,oil degumming,and oil bleaching.Such results were compared to those without BHT addition.To know the quality reduction of these oil extraction some parameters were treated namely FFA level and peroxide value.The BHT concentrations applied were 0.1 and 0,2% and the effect of these addition were monitored during 4 hours with 1 hour testing interval.The result shows that FFA level and feroxide value on bleaching step were lower than those of crude oil extraction and degummuing process.However antioxidant of BHT addition was able to reduce FFA and peroxide value compared to those wihout BHT and these data is very beautiful to know earlier if the oil processed can be processed better further and to prevent unwanted product.

Abstract

The study was conducted to find out the characteristics of tempe made from the mixture of soybean (Glycine max) and corn (Zea mays) which was then compared with those of tempe from soybean. The proprtion of soybean and corn was 9:1 to 5:5. Corn used was the whole corn and corn grits, and all mixtures/proportion produced tempe similar with those made from soybean. Protein content of tempe made from the proportion of soybean and corn 9:1 was in accord with the requirement of the Indonesian Industrial Standard (SII) 0271-80.Tempe with corn grits mixture was prefered in therm taste, aroma, colour,apperance, and its general characteristics.

Abstract

A study on the preservation of salted press-boiled ("pindang") milk fresh (Chanos chanos) by packaging method had been carried out. "Pindang" was prepared eith prepared with or without the addition of potasium sorbate or potasium sorbate. The products were packaged with or without vacuum in the polycello film and stored at room temperature. Observation was done on moisture content, number of peroxide, trimethhylamine, total Bacterial Count (TPC) and organoleptic test. The result showed that up to 8 week of storage, all of the teratments were acceptable. The use of potasium sorbate and sodium eryhorbate combimed with vacuum packaging, showed the best performance.

Abstract

Almost all of Cellulose acetate is produced by reaction of cellulose and acetic anhydride using strong acids as catalyst and acetic acid as a solvent. A typical industrial process requires very high quality cellulose raw materials having a high a-cellulose content. The cellulose used as a raw material in this research is wood pulp of sengon (Paraserianthes falcataria) due to fast growing species and has potential used as a raw material as if has a high cellulose content. The main objective of this research was to obtain condition for making cellulose triacetate by applying applying ratio levels of acetic anhydride toward cellulose in acetylation process. Cellulose triacetate flake was produced by activation and acetylation process. Activation was carried out by mixing cellulose of sengon pulp with glacial acetic in proportion  1:8 at 50oC about 15; 30; 60; 90, and 120 minutes. Acetylation is then conducted using reagents in following proportions relative to the pulp mass; variable of acetic anhydride ratio (3.35:1), (4:1), (5:1), and (6:1), acetic acid as solvent (4.5 : 1), sulfuric acid (0.015 : 1) as catalyst while controlling the reaction temperature at 50oC for 60 minutes. The result showed anhydride toward cellulose 3.35 in acetylation process.

Abstract

The effect of two type of pilot-scale mills on the alveogram values of six varieties of wheat flours were investigated using standard alveograph method. The buhler milled flours produced higher overpressure (P) and detormation energy (w) values, except for hard english flour and lower average abscissa to rupture (L) value, except for frenh flour, than those chopin milled flour.The alveogram values of buhler milled flours can not be used to accurately predict alveogram of chopin milled flours of vice-versa, since their differences were not consistent. Metode standar alveograph digunakan untuk mengatahui pengaruh dua jenis gilingan skala -pilot terhadap nilai alveogram enam varietas tepung gandum. Dibandingkan dengan tepung yang digiling dengan chopin, tepung yang digiling dengan gilingan buhler menunjukan nilai over-pressure (P) dan deformation energy (W) yang lebih tinggi kecuali untuk tepung hard english,dan nilai average abscissa to rupture (L) yang lebih rendah kecuali untuk tepung french.Pendugaan nilai alveogram tepung yang digiling dengan buhler dengan nilai alveogram tepung yang digiling dengan chopin atau sebaliknya tidak bisa dilakukan,karena perbedannya tidak konsisten.

Abstract

Food processed industry is increasing growing in a  row with development of food technology.In along with the fact, utilization of hydrocolloids is also increasing in order to get good quality processed foods. There are many hydrocolloids that can be applied in food industries. Choosing hydrocolloid which is going to be applied for a product will depend on characteristics of each hydrocolloid, characteristics wanted in the product and other consideration factors.

Abstract

Vetiver oil is obtained by distillation. Due to the high cost of production and too small profit margin, farmers tend to reduce the distilling time to a third of its usual practice; e.g. from 36 hours to 12 hours. Young harvested root has also been used now to reduce the cost. All those practices tend to have had influence to the quality of the vetiver oil. Improvements through distillation process and harvesting method seemed need a rather long period. A short cut practice to improve the quality has been carried out by deterpenation process. The result showed that by means of fractional distillation and rejecting the low boiling pint terpenes up to 30% has raised the value of ester number, ester number after acetylation and vetiverol content from 8.17; 119.3 and 46.8% to 13.1; 128.9 and 50.6% respectively.

Abstract

This study was aimed at predicting "dendeng" (Spiced dried meat)shelf life employing the application of arrhenius kinetics.It was based on the moisture content increase,the oxygen consumption. And colour changes of dendeng. The experiment were conducted at there temperature levels i.e. 25 degree C,35 degree C,and 45 degree C and Rh 60%.The Factor strongly influenced in predicting shelf life was temperature.The Arrhenius kinetics method based on oxygen consumption showed good result since it gave the short test shelf life.
