Relying on differences in solubility, an extraction was performed on a mixture of benzoic acid and acetanilide in an attempt to isolate the two compounds.
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 fromwhich 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.
