Overview
ISO 17648:2025 - Quick-frozen coated aquatic products - Specification defines quality, safety and testing requirements for quick‑frozen coated seafood. The standard covers raw and pre‑cooked products made from a single species of finfish, crustaceans, cephalopods or other aquatic animals that have been pre‑treated, coated (batter and/or breading) and quick‑frozen. It also specifies packaging, labelling, storage and transportation rules and prescribes test methods used for quality control.
Key topics and requirements
- Product classification: Categories by species (fish, crustaceans, cephalopods, other aquatic animals) and by processing state (raw coated vs pre‑cooked coated).
- Raw materials and coatings: Requirements for using fresh or frozen aquatic animals, plus definitions and criteria for batter, breading, wet and dry coating.
- Safety limits and residues: Specifies maximum levels for contaminants and veterinary drug residues in aquatic animals, and refers to established tables for compliance.
- Processing & hygienic requirements: Good manufacturing and hygienic practices for coating, optional pre‑cooking (brief frying), freezing procedures and contamination control.
- Organoleptic and physico‑chemical criteria: Sensory (appearance, texture, flavour) and laboratory parameters including central temperature, flesh core content, flesh core moisture and histamine testing to ensure product integrity.
- Test methods: Standardized methods for thawing, cooking, sensory evaluation and physico‑chemical tests; annexes provide detailed procedures (e.g., determination of central temperature and flesh core content).
- Packaging, labelling, storage & transport: Requirements to preserve quality and safety through the cold chain and appropriate consumer information on labels (net mass, ingredients, handling).
Practical applications - who uses ISO 17648:2025
- Seafood processors and manufacturers producing quick‑frozen coated aquatic products (fish sticks, breaded shrimp, squid rings, etc.) to ensure product specifications and market acceptance.
- Quality assurance and laboratory teams implementing test methods for sensory and physico‑chemical checks (moisture, histamine, core temperature).
- Regulatory authorities and import/export inspectors using the standard for conformity assessment and food safety oversight.
- Cold‑chain logistics, packaging designers and retailers ensuring storage and transportation meet temperature and labelling requirements.
- Food safety consultants and certification bodies advising on compliance with international trade expectations.
Related standards
ISO 17648:2025 references and aligns with several food and testing documents, for example:
- ISO 1442 (moisture determination)
- AOAC Official Method 977.13 (histamine in seafood)
- Codex texts: CXC 1, CXC 8, CXC 52 and Codex standards CXS 1, CXS 152, CXS 192, CXS 210
Using ISO 17648:2025 helps producers and stakeholders standardize product quality, protect consumers and streamline international trade of quick‑frozen coated aquatic products.
