• Salmon eggs are common in Japanese sushi and other seafood products; however, certain fish eggs are used as counterfeit salmon eggs which are found in foods and processed products. This study develops a simple, rapid, and cost-effective method for DNA extraction, filtration (FT) and dilution (DL) protocols from a single salmon egg with good DNA quality for real-time PCR amplification. The DNA amount, DNA quality, and real-time PCR performance for different dilutions and different lengths of PCR amplicons were evaluated and compared with the common Qiagen tissue kit (QTK) and Chelex-100-based (CX) protocols. The extracted DNA from a single salmon egg using the FT or DL protocol can be applied in phylogenic research, food authentication and post-marketing monitoring of genetically modified (GM) food products.
