Analisis Korelasi Formalin Dan Protein Pada Ikan Selar (Caranx Leptolepis) Dan Ikan Kakap Merah (Lutjanus Argentimaculatus)

Fish is a food material that has high protein content and amino acid essential that needed for our body. This high protein content makes it decay by microorganisms, therefore it needs to be preservation process in order to stop the decomposition. One of preservative material used is formaline. Formaline is a chemical substance that used for fish preserving because it easy to find and has low cost. In its body, fish can also form a formaline in naturally using enzyme through reduction reaction of trimethylamine oxide (TMAO) with dimethylamine/DMA as by product. This study was purposed to analysis formaline and protein in mackerel (Caranx leptolepis) and red snapper (Lutjanus argentimaculatus) which was obtained from traditional markets in Pekanbaru. Qualitative analysis of formaline used potassium permanganate and chromatophic acid while quantitative analysis used High Performance Liquid (HPLC) and protein analysis used Kjeldahl method. The results showed that from 12 samples of fish all of the samples positive contains formaline which was 6.3352 - 12.2196 mg/Kg and protein in fish was 14.22 - 16.34%. The analysis result of formaline showed that some fish sample were exceed standard of International Program on Chemical Safety (IPCS) in 2002 which is 10 - 20 mg/Kg and can not be considered as food source. According to Acceptable Daily Index (ADI), the consumption of mackerel (Caranx leptolepis) and red snapper (Lutjanus argentimaculatus) by adults with average weight of 50 Kg are 1.1047 Kg/day and 1.5785 Kg/day, respectively. According to the research result there is no correlation between the content of protein on the fish, which can be seen from determination correlation equation that showed value far from 1. The equation (R2) for mackerel (Caranx leptolepis) was 0.252 and for red snapper (Lutjanus argentimaculatus) was 0.062.
