Effects of Protein, Calcium, and pH on Gene Transcription, Cell-Envelope Peptidase Activity of <i>Lactococcus lactis</i> Strains, and the Formation of Bitter Peptides

Effects of Protein, Calcium, and pH on Gene Transcription, Cell-Envelope Peptidase Activity of <i>Lactococcus lactis</i> Strains, and the Formation of Bitter Peptides

Calcium- and protein-rich fermented milk products, such as concentrated yoghurts and fresh cheeses, may contain undesired bitter peptides, which are generated by the proteolytic cleavage of casein. Up to now, it is not clear whether this process is caused by endogenous milk enzymes, such as plasmin...
