Biogenic amines content of four types of Tuscan ewes’ milk “pecorino” cheese was evaluated using HPLC-UV analysis. All cheeses were manufactured in the same dairy factory with different combinations of milk (raw or pasteurized) and type of ripening. Total biogenic amines and tyramine levels of a raw milk “pecorino” ripened five months, partly in a traditional cave, were significantly higher than those of a pasteurized milk “pecorino” with a similar ripening; and of a two months raw milk “pecorino” ripened in the dairy plant. No statistical significant difference was found when comparing total biogenic amines and tyramine contents of the same five month ripened raw milk “pecorino” with a pasteurized milk “pecorino” ripened six months, partly in a traditional “fossa.” In raw milk cave-ripened and “fossa”-ripened cheeses, total biogenic amines exceeded 1000 mg/kg. In cheeses manufactured with raw milk and/or in particular ripening environments, specific hygienic cares are needed to limit biogenic amines formation.

Abstract

Biogenic amines content of four types of Tuscan ewes’ milk “pecorino” cheese was evaluated using HPLC-UV analysis. All cheeses were manufactured in the same dairy factory with different combinations of milk (raw or pasteurized) and type of ripening. Total biogenic amines and tyramine levels of a raw milk “pecorino” ripened five months, partly in a traditional cave, were significantly higher than those of a pasteurized milk “pecorino” with a similar ripening; and of a two months raw milk “pecorino” ripened in the dairy plant. No statistical significant difference was found when comparing total biogenic amines and tyramine contents of the same five month ripened raw milk “pecorino” with a pasteurized milk “pecorino” ripened six months, partly in a traditional “fossa.” In raw milk cave-ripened and “fossa”-ripened cheeses, total biogenic amines exceeded 1000 mg/kg. In cheeses manufactured with raw milk and/or in particular ripening environments, specific hygienic cares are needed to limit biogenic amines formation.
