Abstract: | Formaldehida dapat terbentuk secara alami pada ikan dari proses
pemecahan TMAO secara enzimatis. Penelitian ini menentukan pembentukan formaldehida parameter alami dan korelasinya terhadap kemunduran mutu ikan kantung semar (M. maculata). Pengamatan dilakukan setiap 2 hari sekali selama 14 hari penyimpanan menggunakan suhu chilling. Analisis yang dilakukan uji organoleptik, morfometrik, proporsi bagian tubuh, kandungan proksimat, pH, Total Volatile Base (TVB), Trimetilamin (TMA), formaldehida alami dan Dimetilamin (DMA). Uji organoleptik menunjukan nilai terus menurun selama penyimpanan 14 hari. Nilai pH menurun pada hari ke-2 kemudian terus meningkat setelah hari ke-6 hingga penyimpanan hari terakhir. Kadar TVB dan TMA ikan kantung semar terdeteksi di awal penyimpanan sebesar 2,80 mgN/100g dan 0,93 mgN/100g, lalu meningkat selama penyimpanan. Formaldehida alami mulai terdeteksi pada hari ke-2 pada pengamatan hari ke-14 nilai tertinggi yaitu sebesar 9,39 ppm. Kadar DMA terbentuk pada hari ke-2 dan meningkat hingga hari terakhir dengan nilai 16,34 ppm. Pembentukan formaldehida alami berkorelasi sangat kuat terhadap parameter TMA, TVB, DMA, dan pH. Formaldehyde in fish can occur naturally by an enzymatic breakdown of TMAO. This study aimed to determine natural formaldehyde content and their correlation with quality deterioration of moonfish (Mene maculata). The observations were carried out every 2 days until 14 days of storage in chilling temperature. The analysis included organoleptic, morphometric, proportion body parts, proximate, pH, Total Volatile Base (TVB), Trimethylamine (TMA), natural formaldehyde and Dimethylamine (DMA). Organoleptic value decreased during 14 days storage. The pH value decreased on the day 2 then started to increase after day 6 until the last day of storage. The TVB and TMA levels of the moonfish were detected in the beginning of storage with value 2.80 mgN/100 g and 0.93 mgN/100 respectively. The levels increased until the last day storage. The natural formaldehyde was detected on the 2nd day of observation with the highest formaldehyde level was observed at day 14 with a value 9.39 ppm. The DMA was formed on the 2nd day and increased until the last day storage with content 16.34 ppm. The natural formaldehyde formation correlated very strong with TMA, TVB, DMA, and pH parameters. |
