Abstract:

The main objective of this research was to investigate the possibility of producing fish oil from smoking salmon waste by using cold pressing and wet rendering methods. The amount and the characteristics of extracted of oil were tested. The samples were used about 33.810 kg, smoked fish caused about 9.610 kg. As a salmon waste (skin, viscera, backbone frames and cuts off) it's recorded about 20% of the total mass from salmon slices. The results showed the smoking salmon waste have more than18% of oil fish per one kg of salmon waste. The oil weight from salmon by-products was increased with pressing time increase as well as oil productivity increased. The oil extraction yield increased and characterization of quality. The optimum conditions at pressing time was 180 minutes, oil weight was 93 g oil/500 g salmon by-products, oil productivity was 18.00%, and extraction efficiency were 98.46% at constant pressure. The oil weight from salmon by-products was increased with heating time increase as well as oil productivity increased. The oil extraction yield increased with the wet rendering processes at heating time of 60 minutes have oil weight about 90 g oil/500 g. Salmon by-products, oil productivity about 18.00%, and extraction efficiency was 95.23%. The oil extraction yield increased with the wet rendering processes and characterization of the oil increasing with cold pressing processes. Recent Publications 1.
