Abstract
Tilapia (Oreochromis niloticus) fillets were treated by soaking in 2% sodium pyrophosphate (SPP), sodium tripolyphosphate (STP) and a mixture (SPP + STP, 1:1) solutions before ice storage. Compared with control (without pyrophosphate), pyrophosphates especially SPP treatment effectively inhibited the lipid oxidation as evidenced by lower peroxide values (PV) and thiobarbituric acid reactive substances (TBRAS). The pyrophosphate treated samples also had higher water holding capacity and bright red color, with less off-flavor. In addition, the electronic-nose (e-nose) measured offer-flavor demonstrated a good correlation with PV and TBRAS, suggesting that e-nose assay might be an alternative m..
