Abstract

The raw material used in this study was yellowfin tuna (Thunnus albacares) bone from tuna fillet processing in tuna freezing company. The aimed of this study was produce bone meal as a source calsium. This research consited of two stage, first stage was making fish bone meal and second stage analysis of chemical, heavy metal, calsium and microbial content of fish bone meal. This study used different drying temperature treatment (90 oC, 100 oC, dan 110 oC), and than was analyzed descriptively. Yellowfin tuna (Thunnus albacares) bone meal which was drying temperature treatment at 110 oC had yield (19.37%). The proximate of yellowfin tuna bone meal indicated the best treatment at 110 oC with water content, ash content, protein content, fat content, calcium content were 9.27%, 59.7%, 12.65%, 7.75% and 20.47% respectively. The heavy metal (Cu, Pb, and Cd) and microbial analyzed was safe category according SNI for all treatments.

Abstract

Catfish was a suitable alternative for the main raw material for making surimi, because it has a high protein content, easy to found and than has good prospective to be made surimi product. The aimed of this study to analyze effect of defatting, washing cycle, and frozen storage was add cryoprotectant. This research was conducted three step that is deffating, washing, and made surimi. The concentration of the selected for defatting processed was NaH2PO4 2% during 10 minutes and the result fat content was 0.15%. The best washing was one time of made kamaboko and has gel strength (510.35 g.cm), and the best quality (PLG : 0%; pH : 6.53; water content : 76.6%; folding test : 3.22; bite test : 3,77) when compared with washing cycle two times and three times. The best cryoprotectant addition was 4% trehalose and result of gel strength was 354.15 g.cm for three weeks of frozen storage.
