I have been looking for
something to extend the shelf life of my sauces and came
across calcium
propionate. It's predominantly found in breads and baked goods as a
preservative to inhibit or slow down the growth of mold and prevent
spoilage, but can also be used in dairy, beverages, alcoholic drinks, and
processed meats. It is also used in sauces, jellies, and jams, etc.
