I don't know if this formula can be mixed to get the desired results.
Please ask for advice

hello

I think it can be mixed, but Bisoctrizole has to be separated to be added in the last step instead. can not be dissolved in water first because it may cause problems with the emulsion system

Tried mixing it and it works fine. Get the soft, smooth touch you want.
But the formula is liquid like water. If you want the meat to be a little thicker not flowing too easily
How should I adjust the recipe?

thank you
