Propionihappo

Side effects : No side effects. Propionate is a normal small chain fatty acid and is used in many metabolic pathways in the body.

Carcinogenic property of propionic acid is controversial because it occurs in forestomach which human beings lack. Hence it cannot be considered as a carcinogen to humans*. It is found to be non mutagenic in various organisms**. Studies on rats showed that propionic acid causes change in behavior ( hyperactivity, dystonia) in laboratory rats which is consistent with symptoms of human ASD (autism spectrum disorders)***. It is a normal constituent in food and an intermediate metabolite in human system. Therefore an ADI ‘not limited ‘was established by Joint FAO/WHO Expert Committee on Food Additives (JECFA). It is banned in many countries.

n acidity regulator. All propionates are thought to be linked with migraine headaches. Propionates occur naturally in fermented foods. It is derived commercially from ethylene and carbon monoxide or propionaldehyde, natural gas or fermented wood pulp. It is produced when bacteria decompose fibre.

When the rats' brains were examined later, they were found to have inflammatory processes similar to those in the brains of autistic children, he said."We found, looking at the rats' brains under the microscope, changes that looked a lot like what's occurred from autopsy cases of patients who had autism."It's remarkable that a simple compound like propionic acid would have such a dramatic effect on "normal" animals
