Tuna (Thunus albacares) is usually processed as canned products and in other forms such as shredded (abon) tuna which is produced in home industries. 'Fishy' flavour of shredded tuna is the main problem, due to the trimethylamine (TMA) formation. Citric acid and sodium chloride can minimize this fishy' flavor, and avoid deterioration by decreasing the water activity. The best treatment was combination between 0.5% citric acid and 1.5% sodium chloride.
