This one takes off after sodium benzoate, and there are little Twitter and Instagram animations talking about how this icky stuff belongs in fireworks, not in your Panera food, right, guys? The source for this would have to be this paper from , which analyzed a long list of beverages for benzene contamination, and found that the only detectable levels were in carrot juice intended for infants.
And you thought only aspartame could do it all. Somehow, turning fresh, pure benzoic acid into its sodium salt puts the Curse of the Vat onto it, and this evil stain can never be removed, as we all know. Calcium, technically, is the most common cation in the body, but it gets that title because a lot of it is tied up in bone tissue. They suggested that each student drink a solution with several grams of sodium benzoate and then collect their urine over the next few hours, followed by an extractive workup and crystallization to see who produced the best yield of hippuric acid.
This is a comprehensive review on the use of benzoic acids and benzoates in foods, and the folks at Panera could learn a lot from it.
Now to the toxicology and the regulatory aspects. The EC considers benzoic acid together with the benzoate salts, benzaldehyde, and benzyl alcohol, since they are readily interconverted in living systems.
Values up to 5 to 10 grams per kilo have been reported as the median lethal dose in rats, which is a huge, whalloping amount. There are effects on cells in culture as well, although at levels that would seem difficult to achieve in vivo. Actual commercial levels of the compound tend, apparently, to be far lower than those legal upper limits. Studies from Australia, New Zealand, Turkey, Hong Kong and many other countries have found that the actual daily intake is a factor of five or less than that ADI value.
There are exceptions, though, particularly with concentrated fruit products and with cheeses and yogurt-like products, which has led to some to call for a re-evaluation of all these intake levels. But all that is sanity, backed up by hard data. As many readers will appreciate, you can play the same game with all sorts of other ingredients.
Lactic acid found in milk is used in tanning leather. Palmitic acid, found in meats, coconut oil, sunflower seeds and many other foods, is used in making soap. I could go on all day; any organic chemist could. The entertainment value goes down after a while, because the fundamental premise Good Healthy Natural Stuff versus Toxic Sludge is stupid to start with. Your reasoning is faulty and your science is wrong. Do go on, though. When people talk about wanting to live chemical free, I offer to allow them to experience the inside of a large UHV chamber I have access to.
Elon I need a rocket! Those who want to live in a chemical-free world will need to leave the world and their body behind. Every element found in the basic structure of every piece of wood, drywall, concrete, shingle, tile, stone, bamboo, etc. Every last particle in their bodies, as well is a chemical element. Some blue light will convert your sodium benzoate to benzene, this will not happen with benzoic acid.
I am as mortified by the lack of lack of knowledge of the simplest chemical principles as any chemist. And here comes the but. A routine allergy skin test showed my wife has a strong reaction to sodium benzoate. Then we started reading food labels.
A few sips of any soft drink or some bottled ice teas looking at you Lipton induce hives in her after a few minutes. She has had hives after eating food made with Kikoman but not other brands of soy sauce.
Sure enough there it is on the label. Lately she has been occasionally reacting after eating shrimp or canned crab. I just learned from your article that sodium benzoate may be the explanation, not a protein allergy as I supposed. Nope, protein not required. People can develop allergies to almost anything. Is your wife sensitive to the foods listed in this article which naturally contain sodium benzoate?
These have been a hit or miss cause of hives for her. The tricky part is in restaurants when they are included in a sauce. Salicylate reactions are often seen in the skin and lips, which can be exposed to higher concentrations than other tissues. No, I was wrong. Benzoic acid is excreted as a glycine conjugate, acetyl-CoA is needed for an intermediate step. Probably a low carb diet, where an excess of acetyl-CoA produces ketosis. George Henderson, your comments are very interesting!!
Since I have struggled with a severe reaction to benzoates including benzoic acid when applied to my skin lotion, serums, deodorant, etc.
I DO take alpha lipoic acid, and am wondering if that is interfering with the glycine process to get it out of my system. Bone broth and supplemental glycine does help, but each accidental exposure is worse than before, and I have to go off of benzoate foods for a few weeks. My theory is that when applied to the skin, the glycination process in the liver is by-passed. The recent episode was the result of a well-intentioned massage therapist trying a new lotion without mentioning the change to me.
I am beyond retirement age and must continue to work full time. Can you help? Also, what do you think about the supplements we take with hopes of them being life-enhancing, but interfering with this process of eliminating the benzoates before they cause problems?
Sorry for this confusing comment. I am heading to a spa to spend a few hours in a sauna so that I can feel better. By the way, at the spa there is a mugwort infusion for the women to splash on themselves, as mugwort is said to be good for females. Well, being female, I tried it.
Within 20 minutes, my eyes were itching and I knew I was on my way back to hell. Hurried home and googled mugwort, only to find that it is high in benzoic acid. If you have any help for me I would deeply appreciate it. Thank you very much! Hello, I have recently been diagnosed as having a contact allergy to sodium benzoate in addition to 5 other substances but as I have been reading up on this chemical, I came across your post.
Also, thanks to the many others here who have posted regarding sensitivities to sodium benzoate. Though we may be a small number, I find it very helpful to share information. I stumbled across this comment by accident while looking for information online about sodium benzoate and rash. Myself as well. It is the arrogance of some that creates the ignorance and distrust of the uninformed masses.
Aside from rare cases of allergy possibly to some benzoic acid protein conjugate? It is a seductive fallacy that there can be two benzoates of different origin, alike in their accidents but differing in their essences.
Perhaps I could put some robes on and offer my services to transubstantiate the bad benzoate into good. Can I get any money out of Panera for deceptive advertising if I find some unprotonated benzoate in their cheese or fruits? She also develops hives with potassium benzoate.
I have considered getting some benzoic acid and spreading a few milligrams on her merienda just to see what happens. Both my marital vows and self preservation have prohibited the experiment.
Question from someone with only foggy memories of first-year chemistry: is the concentration of the cation the main thing that determines how much of its salt will be formed? For salts in solution, the proportion of total cations present is the proportion of partners for any given anion. Derek, you are too generous to say their science is wrong. They are not doing science. I actually dislike the taste of benzoate ever since my grandma ruined a batch of homemade cherry compot and jam with it, being overly generous with the preservatives that summer.
As I can usually tell the presence of high-levels benzoate Lipton ice tea, shame on you , and for me the off-taste of benzoate is bothersome, I ended up avoiding sodas, ice teas and juices that list benzoate on the ingredient list. Sorbate is slightly less atrocious taste-wise but I can still tell apple cider with sorbate, by blind testing. I am not against benzoate in general — it is better than food poisoning — but I think it has been overused and given the choice I would rather buy food that is preserved by sterilization or refrigeration.
To quote a Letterman Top 10 from quite some time ago…. Just checked out the ingredient list of some of their breads. Microcrystalline Cellulose!!! Or maybe it is just a fancy name for chopped up firewood… Why would you eat your fireplaces food? So why could one ingredient possible be that bad according to their logic and the other is perfectly fine?
How about some bran??? Some months ago I saw published the results of analyses, conduced by the FDA in response to complaints, of various grated packaged parmesans sold by different stores. As others have mentioned above, sodium benzoate can be a trigger for allergies. Drinking soda that contains it will cause me and several people I know to sneeze profusely.
We applaud what Panera is doing and urge them to do it faster. I actually participated in the Urination Derby as an undergrad back in Our Biochem professor divided the lab into partners.
One had to do the biosynthesis by drinking a measured amount of sodium benzoate, collecting urine over the next hours, and isolating the hippurate. The other had to do a chemical synthesis of hippuric acid from glycine and benzoyl chloride. You could tell the students doing the biosynthesis by their pale faces and stoic expressions—the human stomach is not particularly happy with benzoate solutions.

Formic acid , HCOOH, is found not only in ants but also in the droplets on the tiny hairs of the stinging nettle plant in the family Urticaceae , and the acidity of this compound causes the stinging sensation felt when these hairs are touched. It is the compound that gives the sourness to vinegar and is produced by the bacterial oxidation of ethanol in wine. Household vinegar contains about five percent acetic acid. Acetic acid is important in the metabolic processes of humans and, indeed, of all animals and plants.
