Abstract:
... The species identity on anchovy products was tested through COI mitochondrial DNA sequences analysis in 50 samples belonging to 20 different commercial lots, such as anchovy fillets in vegetal oil, canned anchovies and anchovy paste. Seven samples (14%) were found to be not from Engraulis encrasicolus meats, confirming concerns of species substitution. Conventional COI-DNA barcoding revealed the p ...
