Analisis 3-Monokloro-1,2-Propanadiol (3-MCPD) Ester dalam Minyak Sawit dengan Instrumen Kromatografi Gas-Spektroskopi Massa
Get PDFA group of components called as 3-monochloropropane-1,2-diol (3-MCPD) esters has been found in some vegetable oils, particularly palm oil. Analysis of these components needs GC-MS instrument to reach a low level detection, parts per billion or ppb level. An effort to validate the 3-MCPD esters analysis by GC-MS method (Weiβhaar method) using phenyl boronic acid (PBA) as a derivatizing agent and isotopic internal standard (IS) 3-MCPD-D5 followed by the determination of 3-MCPD in commercial palm oils has been conducted. The analytical results showed the instrumental performance as follows: instrument linearity for the analysis of 3-MCPD standard solutions containing IS 2.0 μg/mL was obtained at a concentration range of 0.25-7.50 μg/mL test solution with R2 higher than 0.990, precision of 3-MCPD as well as IS retention time was less than 2.0% which was acceptable according to JECFA guidance. Instrument detection limit (LOD) and limit of quantitation (LOQ) were read from GC-MS based on the linearity experiment, i.e. 0.17 and 0.59 μg/mL solution, respectively. Method linearity by using palm oil as a matrix also showed R2 higher than 0.990. Recovery test result at 40 μg/g gave an accuracy at 83.29 ± 7.12% which is in the range of AOAC standard (80-110%) and precision at 5.38% (less than RSDHORWITZ). Analysis of 14 palm oils from local market showed 100% of the sampels were positive to contain 3-MCPD esters. 3-MCPD esters in palm oil were found at a concentration range of 8.15-58.14 µg 3-MCPD/g sample

Habitat Lechitocladium Angustiovum pada Ikan Kembung Perempuan (Rastrelliger Brachysoma) di Perairan Teluk Banten dan Pelabuhan Ratu
Get PDFLechitocladium angustiovum is fish helminth parasites in the digestive tract to the Rastrelliger genus. The habitat of helminth parasites divided into microhabitat and makrohabitat. Fish helminth parasites infections showed the interaction of extrinsic factors (hosts habitat) and intrinsic factors (biological host). The study was conducted in February-June 2013 in the waters of the Banten Bay (Banten Province) and Pelabuhan Ratu Bay (West Jawa Province). Microhabitat helminth parasites of L. angustiovum that infect R. brachysoma gastrointestinal tract is the stomach and intestines. The presence of fish helminth parasites in fish is mutually beneficial. Fish helminth parasites get food from the fish but its presence prevents other parasites that infect fish. The presence of these worms in the digestive tract is affected by the presence of copepode and small crustaceans that are influenced by the host biology (growth and gonad development) and environmental waters. The number of L. angustiovum from Banten Bay and Pelabuhan Ratu Bay was not significantly different because of the fish has genetically similar populations.
