DNA barcoding is a powerful sequencing-based tool for the detection of fish species substitution. However, various cooking methods have the potential to reduce the quality and success of DNA sequencing. The objective of this study was to determine the effects of common cooking methods on DNA sequencing results with both full-length (655 bp) and mini-barcodes (208–226 bp), and to determine the optimal methodology to use for species identification of various fish products. Six types of fish (salmon, tuna, scad, pollock, swai and tilapia) were prepared in triplicate using the following methods: uncooked, baked, fried, broiled, acid-cooked, smoked and canned. DNA …

DNA barcoding is a promising method for the sequencing-based identification of meat and poultry species in food products. However, DNA degradation during processing may limit recovery of the full-length DNA barcode from these foods. The objective of this study was to investigate the ability of DNA barcoding to identify species in meat and poultry products and to compare the results of full-length barcoding (658 bp) and mini-barcoding (127 bp). Sixty meat and poultry products were collected for this study, including deli meats, ground meats, dried meats, and canned meats. Each sample underwent full and mini-barcoding of the cytochrome c oxidase …
