In this study, salmon by-products were utilised to produce high ash content (AC) salmon bone powder (SBP) using hydrolytic enzyme and apply in the production of Tra catfish cake. The by- products included 61.9% of moisture, 43.1% of protein, 45.4% of lipid, 10.2% of ash, 3.7% of calcium and 2.3% of phosphorus (on dry weight basis). The AC of SBP achieved the maximal value of 46.9% when hydrolytic enzyme of Alcalase, pH value of 6.5, temperature of 60oC, the Enzyme/Substrate (E/S) ratio of 60 U/g protein and time of 4 hours. The obtained SBP contained 23.1% of calcium, 11.7% of phosphorus and without heavy metals such as cadmium, mercury and lead. The fish cake added with 2% of SBP owned the highest gel strength, folding score and whiteness of 287.4, AA and 65.3, respectively and it was accepted by the test panel. Hence, SBP could be used in the production of Tra catfish cake as a mineral supplement.
