Abstract

Trans fatty acid from commercial frying oils (coconut oil,palm oil, soybean oil and corn oil) were identified to study the effect of thermal oxidation to trans fatty acid forming.Parameters of oil quality analysis were iod number, free fatty acid, peroxide number, percentage of conugated dienae and conjugated triene, and Thiobarbituric Acid (TBA) value. The analysis of trans fatty acid and composition of oils used gas chromatography with 75 m capillary colomn from Supelco SP-2560. Standardized methodologies used for fatty acid methyl ester, quantification of trans fatty acid and oil quality analysis. Heating treatmenr for thermal oxidation was done from initial temperature 180 C in 0 minute and heating time continued until 30, 60, 90 and 120 minute. Trans fatty acid was identified as C18:2:9c, 12t isomer from palm oil, soybean oil and corn oil.These trans featty acid were presented at 0,02-0,325 before heating process and o,04-9,85 after heating process.Trans fatty acid were formed from their natural cis-isomer as result of the high temperature used. Fatty acid composition of frying oils decreased as effect of thermal oxidation. Based on frying oils quality analysis, thermal oxidation decreased the quality of frying oils. Heating time have corellated with decrease of iod number for all of frying oils. Heating time also correlared with increase of free fatty acid, peroxide number,precentage of conugated diene and TBA value. Trans fatty acid could be from thermall oxidation. Results of oils quality analysis, thermal oxidation decreased oils quality and fatty acid composition.

Abstract

Experiment on the use of modified anglo (rural type of stove) and density of bamboo charcoal briquette of Andong (Gigantochloa pseudoarundinaceae) and Petung (Denrocalamus asper) have been carried out to increase its heating efficiency. Observation was carried out on temperature profile, temperature elevation rate, fuel consumption rate and heating efficiency.Analysis on the charcoal briquettes includes moisture content, volatile substance on 950  C, fixed carbon and calorific value.The experiment revealed that the use of bamboo charcoal briquette of Andong and Petung with density respectively of 0.484 and 0.488 in unmodified traditional anglo give heating efficiency of respectively 16.36 % and 17.4 %. Whereas by increasing the density of bambu charcoal of Andong and Petung to respectively 0.5689 gr/cm3 and 0.5021 gr/cm3 and reducing the ventilation of anglo, the heating efficiebcy can be increased to respectively 40.27 % and 45.06 %. Moreover, the tested bamboo charcoal briquette of Andong has moisture content of 6.83 % (wb),volatile substance at 950 C of 22.71 %, Fixed carbon of 71.15 % and calorific value of 6668 cal/g, whereas the bamboo charcoal briqutte of Petung has moisture content of 4.25 % *wb), volatile substance at 950 C of 25.48 %, fixed carbon of 68.19 % and calorific value of 5018 cal/g.

Abstract

Rolling oil is one kind of the lubricants which is used for metal working especially for cold rolling mill (CRM), roll collant, roll oil and pickle oil.Mostly, lubricat based rolling oil was derived from mineral or synthetic oil where its source has been depleted. Castor oil has some advantages to be employed for lubricants or rolling oil based materials since it has high load wear index lubricity, and viscosity as well as low pour point. This research was aimed at investigating the production of rolling oil using castor oil with oxidation treatment. Chitosan was also used to know its effect on rolling oil characteristics. The method of rolling oil production was designed y adding NaHSO4 as catalyst into castor oil, dehydrating of castor oil at 200 C during three hour, cooling of castor oil at room temperature, dissolving buthylated hydroxy toluene (BHT), dehydrating oil (oxidation) at 100 C during 8 hours, addition of 1 %, 3 % and 5 % of chitosan solution into oil, and dissolving O-fenilfenol into oil with oxidation treatment showed better result in term of acid number, iodine number, viscosity, and density. The best result of experiments was showed for the oxidixed rolling oil with dehydrated treatment with 5 % chitosan aolution which has acid value 1,1 mg KOH/gr oil, iodine number 59,3 gr iod/100 gr oil, saponification value 196,9 mg KOH/g oil, viscisity 180, 6 cps, density 0,97 gr/ml. In coclusion higher chitosan concentration resulted lower acid and saponification value. On the Other hand higher chitosan concentration affected higher iodine number and viscosity.

Abstract

Enterobacter sakazakii (recently know as novel genus Cronobacter sp.) is opportunistic bacteria which can cause severe meningitis in neonates. Eight isolates of E.sakazakii which previously isolated from powdered infant formula (PIF) and weaning food were tested foe their ability to survive during reconstitution with water having various temperatures, and their fate during hang time in comparison with 7 isolates previously described by Estuningsih and E. sakazakii ATCC 352/7. reconstitution with 100 C water decreased he number of bacteria of most isolates to undetectable level, while with 40 C and 4 C water did not reduce the bacterial number significantly. Using water of 70 C, reconstitution decreased the number of bacteria of 10 isolates to undectable levels; however 6 isolates survived the reconstitution temperatures. The hang time test showed that some bacteria which were not detected after reconstitution with 70 C water became detectable after 2 hours. Those surviving reconstitution with 70 C well during hang time for 2 to 8 hours.

Abstract

Chitosan is produced commercially in large scale from the other shell of crusteceans as shrimp and crab. At moment chitosan is not used in pharmacy industry but could for other industry as cosmetic, food and beverages,. In cosmetic industry as for skin care preparation like skin lotion, chitosan used for humectant, emulsifier and  stabilizer. The aim of this resarch is to study the effect of chitosan as humectant, emulsifier and stabilizer in hand and body lotion formulation. In this experiment, chitosan was added to hand body lotion product wuth several cocentration level e.g. (F1) without chitosan; (F2) 3 ppm of chitosan; (F3) 5 ppm of chitosan; (F4) 10 ppm of chitosan and (F5) 25 ppm of chitosan. Hand and body lotion produced was tested with some testing parameters including homogenity, pH, viscosity, emulsion stability, evaporated and organoleptic for colour, aroma and stickiness. The result showed that the best treatment was F3 (5 ppm of chitosan), the best of homogeneity level, everages pH 6,37, viscosity 1660 cps, evaporation only 78,29 % and organoleptic test score averages was 4,02.
