Abstract

The studies have been done about the transformation of safrole into isosafrole. The transformation wasdone using reagents, namely t-BuOK/DMSO and KOH/CH2OHCH2OH. The purities of all products weretested with thin layer and gas chromatography. Thereafter the structures were identified with infraredspectrophotometers, NMR1H and 13C spectrometry, and mass spectrometry. The isomerization product ofsafrole into isosafrole with highest percentage yield (97%) was given t-BuOK/DMSO.

Abstract

This Research was to determined of the total of phenol content and also to test the antioxidant activity of four lalapan leafs that are kemangi (sweet bacil, Ocinum Bacilicum), kemang (Mangifera kemanga), selada (cress) and also poh pohan (Pilea trinervina). The total of phenol content of extract of lalapan leafs determined as tannic acid, whereas the test of antioxidant activity determined by method of diene conjugation. The result of analysis indicated that the total of the highest phenol content is extract of kemang leaf (1,14 mg/g), followed by pohpohan (0,84 mg/g), kemangi (0,68 mg/g) and also selada (0,54 mg/g). Pursuant to concentration of diene conjugation, knew that the kemang has the highest activity than the other lalapan leafs.

Abstract

Mayonnaise represent the system of emulsion of oil-in-water, where oil rate is 50-85%. Height of oil rate of mayonnaise causes of the oxidation reaction more easy. The aims of this research where to study the effectiveness of antioxidant on its system. The effectiveness of antioxidant in the system attributed by its polarity. The polarity of antioxidant was measured by determining of partition coefficient in octanol-water system (1:1). The effectiveness of antioxidants in the system were determined by Rancimat. Result of this research indicate that third type of antioxidants have the different polarity. The partition coefficient of butylated hydroxyl toluene (BHT) was 91%, t-butylhydroquinone (TBHQ) was 79.9%, and trollox was 0.47 (32.0%). From the Test of Rancimat known that the most effective type of antioxidants was TBHQ.

Abstract

A research was done to isolate and identify eugenol from clove stalk of Zanzibar variety. Isolation of clove stalk oil was done using steam destilation technique, and for identification using Gas Chromatography-Mass Spectrophotometer. The isolate from clove stalk oil of Zanzibar variety, fresh and dried variable has 0,565% and 0,485% yield. The oil was yellow and has cloves scent. From the test of clove stalk oil quality, fresh and dried variable was known that its water content were 0,22% and 0,33%., specific weight 1,027 and 1,068 g/mL., with refraction index 1,5186. Beside eugenol, GC-MS analyzes showed that other constituent component in clove stalk oilw were methyl benzena, methyl salisilat, caryophylin oxide, trans-caryophylin, a-Humulene. Eugenol can be isolate from clove stalk oil by the addition of NaOH, acidify with HCl and then extracted using petroleum eter as a solvent. Eugenol that obtained from clove stalk oil, fresh and dried variable were 66,47 % and 76,92%, respectively. Eugenol analysis from isolated clove stalk, fresh and dried variable has 90,10% and 93,96% purities, respectively. Eugenol obtained from fractionation was analyzes using GC, and spiking technique identification.

Abstract

Pengasapan menggunakan asap cair telah lama diperkenalkan, namun pada umumnya asap cair belum popular di masyarakat karena sulitnya membuat peralatan pirolisis serta keterbatasan bahan dasar kayu, oleh karena itu, perlu dilakukan pembuatan asap cair dengan metode pembakaran langsung menggunakan bahan dasar sabut kelapa. Penelitian ini dilakukan guna mengetahui komponen-komponen penyusun asap cair sabut kelapa yang dibuat dengan metode pembakaran langsung. Guna meningkatkan kualitas asap cair, dilakukan distilasi serta penjerapan asap menggunakan arang aktif. Analisis komponen-komponen dilakukan dengan Kromatografi Gas dan Spektrofotometer Massa (GC-MS). Hasil penelitian menunjukkan bahwa Asap cair sabut kelapa sedikitnya mengandung 21 komponen, asap cair hasil distilasi sedikitnya mengandung 31 komponen dan asap cair hasil penjerapan dengan karbon aktif mengandung sedikitnya 5 komponen. Komponen paling dominan dalam asap cair adalah asam asetat. Konsentrasi asam asetat dalam asap cair asli adalah 0,99 %, asap cair hasil distilasi adalah 1,0245 %, sedangkan asap hasil penjerapan menggunakan arang aktif adalah 0,25%. Dengan demikian, maka proses distilasi dapat meningkatkan kualitas asap cair sabut kelapa yang dibuat menggunakan teknik pembakaran langsung.

Abstract

Fish represent the ordinary food substance consumed especially for society which live in the coastal area like Town of Manado of Sulawesi Province. This research has conducted to isolate fish oil from cakalang, malalugis, visceral extracted by refluks for 7 hours using chloroform as eluent. Oil quality yielded examined by the acid value and also fatty acid profile determination use the gas chromatography .technique. The purification used the adsorption chromatography by active charcoal.has done to improve the quality of fish oil The result shows that yield of oil obtained from Cakalang fish waste was: 4,67 %, The acid value from Cakalang fish oil was 20,08 %. The EPA and DHA content from cakalang waste oil was 17,96 mg100g oil and 103,08 mg/100g oil There were difference result of fatty acid profile from the purification process. Rate of EPA and DHA was degrade after purified. Keywords: fish oil, cakalang, Manado, adsorption chromatography

Abstract

This research was done to study benzo(a)pirene content produced from liquid smoke by directburning process, also how to reduced the component. The results show that liquid smoke from coconutpericarb that produced by direct burning method has 28% recovery. The smoke was yellow to brown,smelled as smoke with density 0,9965 g/mL. To reduce benzo (a) pirene of liquid smoke was done usingredistilled and absorbed with active carbon. Redistilled liquid smoke was done at 98-100 oC. RedistilledLiquid smoke almost colorless and no color compared with initial liquid smoke, less smoke scent. Thedensity was 0,9970 g/mL with 55% recovery from initial smoke. Absorbed liquid smoke using activecarbon (1:5) was acquired more clear liquid, no color and no scent, density 0,9975 g/mL with 51,7%recovery. Benzo(a)pirene concentration can be reduced using redistilled and absorbed with activecarbon method. Reduce concentration using redistilled technique was 33.1%, whereas using absorbedtechnique was 54,3%.
