Emulsions during the defat IME I've never had that problem as it's like any of the stages you shouldn't shake or air-ate the mix you should treat it like a lady , start of slow then as it gets hotter ( with the use of lye ) the faster you can go !! Lol just jokes
No just be gentle with the acidified mix no need to shake the shit outta it !
but with the use of salt I don't see an advantage !
