Tainting and Depuration of Taint by Lobsters (Homarus americanus) Exposed to water Contaminated with a No. 2 Fuel Oil: Relationship with Aromatic Hydrocarbon Content in Tissue

AbstrakTujuan penelitian ini adalah untuk mengetahui perbedaan bahan pengasap yang berbeda terhadap uji sensorik, proksimat, Polycylic Aromatic Hydrocarbon (PAH) pada pokea asap.Penelitian ini menggunakan rancangan deskriptif yang terdiri dari Pokea asap dengan menggunakan bahan pengasap tempurung kelapa (A1), cangkang kelapa sawit (A2), tempurung kelapa dan cangkang kelapa sawit (A3). uji sensorik pada penelitian ini menunjukkan hasil pada pokea asap nilai aroma tertinggi yaitu 6,6 (A1), Warna tertinggi yaitu 7,3 (A1), Umami tertinggi yaitu 5,9 (A2), Saltiness tertinggi yaitu 5,6 (A1), Tekstur tertinggi yaitu 5,2 (A1) dan (A2). Berdasarkan kandungan proksimat, kandungan kadar protein hasil tertinggi pada pokea asap dengan bahan pengasap cangkang kelapa sawit. Kandungan Polycyclic Aromatic Hidrocarbon kandungan (benzo(a phyrene) hasil terendah pada pokea asap dengan bahan pengasap tempurung kelapa. Kata kunci: Pengasapan, Batissa violacea, tempurung kelapa, cangkang kelapa sawit AbstractThe purpose of this study was to evaluated the sensory quality, proximate content and Polycylic Aromatic Hydrocarbon (PAH)profile onsmoked pokea.This study used a descriptive design consisting of Pokea smoke using coconut shell smoked (A1), oil palm shells (A2), coconut shells and palm shells (A3). Sensory test in this study showed that the highest pokea value of smoke was 6.6 (A1), the highest color was 7.3 (A1), the highest color was 5.9 (A2), the highest saltiness was 5.6 (A1), The highest texture is 5.2 (A1) and (A2). Based on the proximate content, the highest content of protein content in pokea smoke using oil palm shell as smoke source. The content of Polycyclic Aromatic Hydrocarbon content (Benzo(a)phyrene)is the lowest result in smoke pokea with coconut shell smoked.Key words: Smoking, Batissa violacea, coconut shell, palm oil shell

Abstract An ultraviolet absorption test to limit the total polycyclic aromatic hydrocarbon content in petroleum waxes has been developed. The procedure consists of extraction of a solution of melted wax in an aliphatic solvent with a dimethyl sulfoxide-phosphoric acid mixture, followed, if necessary, by chromatography on a magnesia-Celite column. Recoveries of representative polycyclic aromatic hydrocarbons, added at a level of 12.5 μg to 25 g samples (0.5 ppm) of wax, ranged from 64 to 93% after the extraction part of the procedure, and from 44 to 85% after the column chromatographic part of the method. The variations in the recoveries may be attributed to the differences in the partition coefficients of the hydrocarbons between the aliphatic solvent and the dimethyl sulfoxide-phosphoric acid extraction mixture, plus the tendency of some of the compounds to be oxidized during the chromatographic part of the test. The procedure has been applied to the analysis of commercial, refined petroleum waxes, and specifications have been developed to limit the total polycyclic aromatic content of such waxes for food additive use.
