Pengaruh Perbedaan Lama Pengasapan Terhadap Mutu Ikan Baung (Hemibagrus Nemurus) Asap Selama Penyimpanan Vakum Pada Suhu Dingin
The study was aimed to examine the effect of different smoking time on the shelf life and the characteristic changing of chemical and sensory during storage. Samples of 250 gr each of cathfish baung were obtained in the village of Paku River, the Regency of Kampar Riau. The fish was butterfly form split and then smoked at temperature 50-70°C for different smoking times, namely: 4 hours (L4), 5 hours (L5), 6 hours (L6), 7 hours (L7). The smoked fish were packed vacuum in plastic bags and stored in refrigerator at cold temperature (±5°C) and then observed on the first day, 5 days and 10 days. Parameters measured included sensory quality (appearance, odor, and texture), chemical analysis (peroxide and TBA), and microbiological analysis (TPC). The result showed that the longer the smoking time, the higher the sensory value, but the lower the TBA and TPC value. The different smoking times were significantly affecting to the valueof sensory, TBA, and TPC of the smoked fish. The best treatment was indicated by the smoked cathfish which were smoked for 7 hours (L7). The product showed the lowest TBA values, those were (4.20 mg malonaldehyde/kg) at the first day, then became (4.28 mg malonaldehyde/kg) after stored for 5-10 days. It was invested by microbes at 1.0x103 cfu/g on the first day and increased became 6.3x105 after stored for 5 days and then became 2.2x106 after stored for 10 days. All product were rejected by panelists after being stored for 5 days.
