Decreasing Tyramine in
Natural Cheese
It is known that
biologically active amines (such as tyramine and histamine) are produced during
cheese maturation through the enzymatic decarboxylation of their corresponding
amino acids. However ingesting cheese that contains tyramine can result in a
"cheese effect" or "cheese reaction" that manifests itself
through physiological effects such as hypertension, headaches and nausea. In
this study, methods for decreasing tyramine content were applied to both a test
tube environment and the actual production of sample cheeses. The parameter
variables investigated were salt content, temperature during maturation, and
the type lactic bacteria starter.
The addition of salt
repressed tyramine production in the test tube environment, but a similar
increase in salt content during the production of sample cheeses did not have
any effect. Tyramine production was effectively minimized in both the test tube
environment and the sample production, however, through temperature controls
during cheese maturation and an appropriate selection of lactic acid bacteria
starter.
