2.2. Phosphate application method
Shrimp samples were divided into three groups of 300 g and
immersed in a 5 g/100 mL food grade sodium tripolyphosphate
(STPP, Astaris), or in a 5 g/100 mL blend solution (sodium tripolyphosphateþ
sodium tetra pyrophosphate þ NaCl, Globalfood), or in
tap (potable) water (control group), at 2 C, for 120 min, according
to procedures of Gonçalves and Ribeiro (2008a). Next, samples
were drained for 30 s and submitted to a freezing process. Three
replications for each group were accomplished.
