[DNA-based methods for identification of seafood species]

Area of Science:

• Molecular biotechnology
• Genetics
• Food science

Context:

• Advancements in molecular biotechnology have led to DNA-based methods for seafood species identification.
• Current DNA techniques (FINS, PCR-RFLP, specific-PCR) are applied to various seafood forms (fresh, frozen, processed).
• Accurate identification of mixed seafood species remains a significant challenge.

Purpose:

• To review recent progress in major DNA-based methods for seafood species identification.
• To discuss the current limitations and future perspectives in the field.
• To emphasize the critical role of gene databases in species identification.

Summary:

• This paper reviews established DNA-based techniques including FINS, PCR-RFLP, and specific-PCR for seafood authentication.
• It highlights the limitations of current methods in accurately identifying mixed seafood species, both qualitatively and quantitatively.
• The importance of comprehensive gene databases as essential resources for seafood identification is underscored.

Impact:

• Provides a comprehensive overview of DNA-based seafood identification technologies.
• Identifies key areas for future research and development, particularly for mixed-species analysis.
• Contributes to ensuring seafood authenticity, safety, and regulatory compliance through improved identification methods.
