I'd avoid the potassium chemicals. I've tried the potassium based
baking powders in the past and it alters the taste and not in
a favorable way. Though this does indicate the nervous
Nellies concerned that a trace of potassium will kill is
overblown and reflects a lack of understanding of
what is going to be eaten here that is the solid not the
liquid.
All food is liquified by the time it reaches the duodenum.
The brine is drained off and not eaten. Hence a share of
the potassium would do down the drain, if it is even
effective.
However,
the duodenum is the location where the gastric juices are flooded with
large amounts of potassium secretion from the pancreas. The
intestinal bioavailability of potassium is actively controlled by ion
pumps at the cellular level, and that is the reason why the GI route
has a certain safety margin over the intravenous route. However, even
the gastric route can be overwhelmed. Most especially in people with
any level of kidney impairment or blood flow to the kidneys such as in
any type of heart failure or prolonged severe hypertension as the
kidney is the only route of egress from the body for potassium (except
for bilious vomiting). Hyperkalemia is a life-threatening emergency
precisely because it is so difficult to remove from the body, and
because the concentrations for optimal function are so low (two orders
of magnitude lower than sodium) that it does not take much to exceed
safety margins.
Be aware, also, that the amount of potassium chloride required to
cause conduction abnormalities in the heart is nowhere close to the
dose used in Lethal Injection which is unnecessarily high in order to
never be in the margin of error when executing a prisoner (what a
bloody disaster that would be). Potassium chloride is never used as a
direct injection in the ICU as being far too dangerous. Patients who
required potassium supplementation always received it very slowly and
gradually over a period of time, massively diluted in the IV.
The upshot of all that is that using it to make tofu is likely safe
for a totally healthy individual, but not exactly a first choice if
one plans to eat a daily diet dominated by it, and not if the
individual has any reason to be concerned about cardiac or renal
function. Moderation is the key.
Tofu isn't on my food list of late. Too many isoflavones
for my taste :-(
