The short answer is no. ECA won't help with the fermentation of the meat which is the hallmark of a dry cured sausage. ECA will help lower the PH of the sausage but not enough to reign in the bad bacteria.
Some people say you can ferment sausage using yogurt i have never tried it maybe in the near future i will. But if your looking for a cheaper alternative than bactoferm you can read more up on it!!
Im allergic to yogurt cultures too unfortunately.
