Mark, I can confirm this as what I have observed in making bio from tallow, or having a fair percentage of it ~ 30%.
It does tend to foam but I think this is more likely stearins as it ; left a lovely greasy residue when the tank was emptied, mist washing would tend to take it down to the bottom, where I nearly always found a lovely creme cheese layer of this stuff, I was not yet been able to make a batch without it, although a properly titrated acid base reation tends to minimise it. Is it harder to convert, no just a bit more work to seperate the eash products. Alledgedly if you make biodiesel, which no one here does! Just my experience in times past.
