Effects of chitosan and sodium alginate active coatings containing ε-polysine on qualities of cultured pufferfish (Takifugu obscurus) during cold storage.
Int J Biol Macromol. 2020 Oct 01; 160:418-428.IJ

Abstract

The present study evaluated the effects of chitosan (CH) and sodium alginate (SA) bioactive coatings containing 0.1, 0.2 and 0.3% ε-polylysine (ε-PL) combined with high CO2 modified atmosphere packaging conditions (MAP, 60% CO2/5% O2/35% N2) on the quality of cultured pufferfish (Takifugu obscurus) at 4 °C for 18 days. Results showed that CH-SA coatings containing ε-PL and high CO2 MAP treatments could significantly lower total viable count (TVC), Pseudomonas spp., H2S-producing bacteria and lactic acid bacteria counts (LAB), and reduce the productions of off-flavor compounds including total volatile basic nitrogen (TVB-N), trimethylamine (TMA) and ATP-related compounds. Volatile compounds were identified and quantified by SPME gas chromatography-mass spectrometer (SPME-GC/MS) for pufferfish during cold storage and the bioactive coating treated pufferfish significantly lowered the relative content of fishy flavor compounds, such as 1-octen-3-ol, hexanal, (E)-2-octenal, octanal and 2,3-butanedione. Further, CH-SA coatings containing ε-PL and high CO2 MAP treatments could more efficiently retard the water migration by magnetic resonance imaging (MRI) results, and maintained the quality of pufferfish during storage at 4 °C according to organoleptic evaluation results.
