[Nature of ingredients].
Angiotensin II is a hormone that increases blood pressure, and the enzyme involved in its production is angiotensin-converting enzyme (ACE). ACE converts angiotensin I to angiotensin II in the "renin-angiotensin-aldosterone system", which is responsible for blood pressure elevation. By inhibiting this conversion, the production of angiotensin II is suppressed and blood pressure is lowered, which is the mechanism of antihypertensive drugs generally known as 'ACE inhibitors'.
Sake cake contains peptides that suppress the action of this ACE.
There are several ACE-inhibitory peptides that are recognised as ingredients in food for specified health uses, including those derived from sardines, milk, sesame, wakame and soya as well as sake lees.
