Shelf-life of loricariid catfish (Pterygoplichthys disjunctivus [Weber, 1991]) roe stored in ice

Loricariid catfish (Pterygoplichthys disjunctivus [Weber, 1991]) has invaded water catchments throughout the world, due to lack of predators and high fecundity. An approach control its population could be using roe as food; however, more knowledge is needed. Thus, present study aimed evaluate shelf-life fresh loricariid stored in ice, an for possible food utilisation. Physicochemical characteristics (moisture content, aw, pH, hardness, colour), protein electrophoresis (SDS-PAGE), amino fatty acid contents, oxidative stability (TBARS) microbiology were analysed at 0, 2, 4, 6, 11, 15 21 days. Moisture content (58.5 ± 2.1 vs. 60.4 1.2%), aw (0.89) pH (5.87 0.14 5.96 0.03) shelf-stable (initial final day, respectively). SDS-PAGE showed minor hydrolysis protein. Ice storage increased free concentration, confirming proteolysis proteins/peptides with not impact on TBARS (2.4–3.3 mg malonadehyde/kg sample). ice (P. roe, under conditions, proved effective preservation method utilisation, maintaining physicochemical microbiological up 20
