Feasibility of Solid Waste Tuna Loin of Yellowfin Thunnus albacares Raw Materials for The Product Diversification

Abstract

<p>Indonesia is one country in the world exporters of tuna in the form of fresh, frozen and<br />processed. Tuna exported in processed form large enough to leave waste for exporting companies.<br />The purpose of this study was to determine a feasibility study on solid waste exported tuna loin for<br />raw material diversification. This research was conducted in Majene Makassar Strait. The study was<br />conducted using descriptive exploratory method by taking a sample of 3 times and each sample<br />was tested 3 times resulting in 9 times of testing for each of the observed variables. Chemical test<br />which includes moisture, protein, fat, ash, carbohydrates, and histamine. Microbiological test that<br />is E. coli, Salmonella and the total number of bacteria. Data were analyzed by descriptive qualitative<br />and quantitative display via Tables, Graphics and Image in the form of average value. The results<br />showed that the chemical solid waste tuna loin has a water content ranged from 78.34 to 78.78%,<br />protein content ranged from 14.32 to 16.41%, fat ranged from 1.56 to 1.66%, ash content ranged<br />from 5.18 to 5. 58%, carbohydrate content ranged from 1.29 to 1.34%, and histamine ranged from<br />2.08 to 3.21 mg / kg. Solid waste microbiologically tuna loin contains E.coli range from 1.2 to 1.9<br />(&lt;2), Salmonella negative and TPC ranged from 1.4 to 1.8 x 105 kol/g. The results of chemical and<br />microbiological testing showed solid waste tuna loin still suitable as raw material diversification<br />products.</p>
