To obtain a value-added product from the non-toxic brown-backed toadfish Lagocephalus gloveri (pufferfish), we developed a retort pouched pufferfish soup (RPS) and characterized its processing conditions and quality metrics. We found that the most appropriate manufacturing process for the RPS consisted of detoxifying and cold-water dipping the pufferfish flesh, blanching it, and adding it to the retort pouch along with other ingredients (hot-water extract of pufferfish head and carcass, radish, bean sprouts, and garlic), after which the pouch was sealed, sterilized (120℃, F₀ value 7.5-10 min.), cooled, and inspected. The moisture, crude protein, and total volatile basic nitrogen contents of the RPS were 97.2%, 1.3% and 7.7 mg/100 g, respectively. The total free amino acid content was 903.2 mg/100 g, and the main free amino acids were glutamic acid, taurine, lysine, glycine, threonine, alanine, arginine, proline, and hydroxyproline. Sterilizing the RPS for up to F₀ value 10 min. did not cause any major problems in terms of chemical or sensory qualities. This RPS has good storage stability and organoleptic qualities compared with similar commercial pufferfish soups and is suitable for commercialization as a value-added instant seafood soup.
