For years I only heard about Calcium propianate as a mold inhibitor. This week I have been researching fruit fly medium and have found paraben (Tegosept) in several recepies.

Does anyone know the difference between them?

I have just found a local place that sold CP, and was only able to purchase a 11Lbs bag, so I have a lifetime supply of mold inhibitor.
calcium propionate is a synthetic substance, while paraben is a natural substance derived from plants.
Thank you very much
