Thousands of years of boiling ayahuasca in south America, and all that modern pressure potting on even higher temperatures 120 °C (248 °F), all that has never damaged the alkaloids.
As long as it's in an acid stage, the alkaloids are in salt stage and you can boil the heck out of it no problem. Just keep heat away where the alkaloids are in their freebase stage, that is another story all together.
Since the egg tek is executed in an acid stage, no worries :thumb_up:
Try to quote one of those when it involves an acid stage.
I suspect you mix up with the advice to keep temp low (say max 40 deg C) when making the non polar pulls, for two reasons:
* pulls are done in a base stage (freebased alkaloids = way more vulnerable to temp);
* more temp drags more waxes and plant oils/fats & whatnot into the non polar layer.
BTW this is a snippet I kept from another forum about egg white tek:
I'd suggest to do 4. at room temp, certainly not warm, at this stage you want the soup to become milk-ish without any egg white solidification. Only from point 5. the heat goes on.
2 cents.
