Dna Barcoding Methodologies For The Identification Of Fish Species In Cooked Products, Rosalee S. Hellberg
Food Science Faculty Books and Book Chapters
Deoxyribonucleic acid (DNA) barcoding is a sequencing-based method that utilizes a standardized genetic region to identify species in combination with a reference database. DNA barcoding methodologies have been extensively applied to the identification of species in cooked seafood. While the typical genetic target associated with DNA barcoding is a ~650-bp region of the gene coding for cytochrome (cyt) c oxidase subunit I (COI), additional genetic targets include partial regions of the cyt b and 16S ribosomal ribonucleic acid (rRNA) genes. Most categories of cooked seafood can be identified using ~400- to 700-bp regions of these genes; however, canned seafood and …
