Fortification Fish Meal Skipjack Tuna (Katsuwonus pelamis) on the Characteristic of Sago Noodles

Abstract

The effects of different immersion method namely water, 3% acetic acid and 0.8% sodium bicarbonate at immersion time (2, 4, and 6 hours) on the physicochemical characteristics of skipjack tuna fish meal were studied. Producing of fish meal with 0.8% sodium bicarbonate immersion for 6 hours had better characteristics than the water and 3% acetic acid with increased in protein content by 82.86% and decreased in fat content by 1.10%. Sago noodle characteristics with the fortification of fish meal were investigated. Result of organoleptic evaluation showed that the fortification of fish meal had a positive impact in the assessment of aroma and flavor, however there were no effect in texture of the sago noodles. Fortification of 8% fish meal gave the best aroma and taste of the sago noodles. Whiteness decreased slightly with no fortification of fish meal concentration. Control and commercial sago noodle showed the internal structure of a compact and smooth compared with the addition of sago noodle 8% fish meal and wheat flour noodles. Optimum concentration fortification of fish meal to increase in protein content of sago noodles was by 8% fish meal.
