ANALISA TOTAL BAKTERI PADA IKAN TUNA ASAP YANG DIRENDAM DENGAN ASAP CAIR “WAA SAGU” SELAMA PENYIMPANAN PADA SUHU KAMAR

Abstract

Backgroud: During this traditional way of preserving fish is usually done by fumigation but is now developed another preservation method that uses liquid smoke method.
 Method: Liquid smokes used in this study are from the liquid smoke “waa sago” with concentration 5% + NaCl 5%, soaked 10 minute, the type of fish used tuna (Thunus sp). Meat tuna soaked in liquid smoke and stored for 10 days at room temperature. This study aimed to determine the microbiological quality (total plate count), soaked smoked tuna with liquid smoke "waa sago" during storage at room temperature.
 Result: Results of analysis of total bacteria in smoked tuna still eligible SNI and safe and suitable for consumption. Liquid smoke "waa sago" can extend the shelf life of tuna fish for 10 days at room temperature. Liquid smoke has antibacterial properties more easily applied and more secure than conventional smoke and tar fraction containing aromatic hydrocarbons have been separated, so that the products are free polutean liquid smoke and carcinogens.
 Conclusion: Total bacteria in tuna, marinated with liquid smoke waa sago stored for 10 days, still meets ISO standards. Liquid smoke from sago waa potential as an antibacterial because it can maintain the quality of smoked tuna microbiologically during storage at room temperature.
