It also occurs naturally in butter and some types of cheese. propionate keeps bread and baked goods from spoiling by preventing mold and bacterial growth. Although you may be concerned about the idea of preservative use in food, on the flip-side, you certainly don’t want to eat bacteria- or mold-infested bread.

has been studied extensively for toxicity and as a potential cancer-causing agent in the laboratory, and all the findings were negatives. Only young and vitamin B12 deficient rats that were fed enormous amounts of (many times more than is possible from a normal diet) in one study showed a decrease in growth rates. Rats fed large amounts of and similar chemicals over longer periods of time have not shown any negatives effects. The accumulation of research evidence shows that is non-toxic and safe to use in the typical amounts currently used by food manufacturers.

There are anecdotal claims that some people who are sensitive to calcium propionate may suffer from migraine headaches triggered by exposure to foods that contain it. However, there does not appear to be any medical research that backs that claim. Calcium propionate does not build up in any body tissues; after you eat food with calcium propionate, the body splits the calcium apart from the propionic acid, which is easily absorbed and metabolized like all other fatty acids.
