Proteolysis of the semi-hard cheese Herrgard made at different dairies. Exploratory study
Författare
Summary, in English
The casein breakdown, peptide hydrolysis and accumulation of amino acids were studied in the semi-hard Swedish cheese, Herrgard produced at 3 dairies. Casein components were analysed by capillary electrophoresis, and peptide profiles as well as amino acid composition with reverse phase HPLC. Ten cheeses from the same vat of each of the 3 dairies were analysed; 5 cheeses each after 3 and 6 months of ripening. The peptide profiles revealed significant quantitative differences that most probably are explained by variations in composition of starter and non-starter lactic acid bacteria in cheese. The cheeses from one dairy could be separated from the other cheeses by their amino acid composition that reflected a larger amount of starter bacteria being viable for a longer time. Variation in plasmin activity between cheeses from different dairies was shown as well as a relation between plasmin activity and amount of total free amino acids released by microbial activity.
