Super Safi’s Monday Morning Musings 64 – Potassium Benzoate

Morning Musically-Minded, Medically-Minded, Masticators!

(Today’s post is sponsored by the letter “M”)


Over the past 600+ episodes, The Simpsons has taken us on an amazing journey involving music, science, and food to name a few concepts.

And what better way to start your week, then by discussing some of these concepts Monday morning?

So let’s get started this week by talking about a common food preservative, potassium benzoate.

In the sixty fourth episode of The Simpsons, Treehouse of Horror III (Season 04, Episode 05), the third annual fright fest features three new anthologies.

In the second segment, King Homer, a parody of King Kong, Homer as King Kong is captured by Mr. Burns and falls in love with a damsel in distress portrayed by Marge.

In the third segment, Dial “Z” for Zombies, Bart and Lisa accidentally recite a spell that unleashes zombies upon Springfield.

But for this musing, we will focus on the first segment, Clown Without Pity.

It’s Bart’s birthday and Homer forgets to buy him a gift. He rushes out to the ‘House of Evil’, where the Shopkeeper helps him find a Krusty doll.

Shopkeeper: “Take this object, but beware it carries a terrible curse.
Homer: “Ooooh, that’s bad.
Shopkeeper: “But it comes with a free Frogurt!
Homer: “That’s good.
Shopkeeper: “The Frogurt is also cursed.
Homer: “That’s bad.
Shopkeeper: “But you get your choice of topping!
Homer: “That’s good.
Shopkeeper: “The toppings contains Potassium Benzoate.” [Homer looks confused] “That’s bad.
Homer: “Can I go now?

Homer returns with the Krusty doll, much to Bart’s delight. However, Grampa also echoes the Shopkeepers warnings about the evil doll:

Grampa: “That doll is evil, I tells ya. Evil! Eeeeeeviillll!!!
Marge: “Grandpa, you said that about all the presents.
Grampa: “I just want attention.

Both the Shopkeeper and Grampa are correct as the Krusty doll repeatedly tries to kill Homer.

Homer also repeatedly and unsuccessfully tries to get rid of the doll. As the doll attempts to strangle Homer, Marge calls KrustyCo for help. A KrustyCo repairman arrives and discovers that the doll has been accidentally switched from ‘Good’ to ‘Evil’. He flips the switch back to ‘Good’ and Homer uses the doll as a pleasant and obedient servant.

But have you ever wondered what the potassium benzoate in the frogurt topping is?


Potassium Benzoate

Potassium benzoateis a food preservative that inhibits the growth of mold, yeast, and some bacteria. It works best in low-pH products, with pH below 4.5, where it exists as benzoic acid.

Acidic foods and beverages such as fruit juice (citric acid), sparkling drinks (carbonic acid), soft drinks (phosphoric acid), and pickles (vinegar) may be preserved with potassium benzoate. It is approved for use in most countries, including Canada, USA, and the European Union.

According to the Canadian Food Database (, potassium benzoate belongs to the class of organic compounds known as benzoic acids. These are organic compounds containing a benzene ring which bears at least one carboxyl group. Potassium benzoate is a weakly acidic compound (based on its pKa). Here are the properties of potassium benzoate:



Now that we’ve learned more about potassium benzoate, be sure to come back next week when we continue our Monday morning musings with the next episode of The Simpsons.

  1. Potassium Benzoate (Benzoic Acid) – Some research further suggests that young children exposed to benzene or benzoic-acid-containing compounds like potassium benzoate may have a higher risk of attention deficit hyperactivity disorder (ADHD). πŸ€”

    Yeah, TREEHOUSE OF HORROR III aka that Episode which gave TSTO King Homer with King Homer’s Skyscraper (November 2013 Community Prize – has it truly been that long ago? πŸ€” ), House Of Evil (darn it, I still don’t have the Evil Shopkeeper!), and Krusty Doll (and that, too!)

    OMG 😱 I better stop here (or I could list more!) πŸ˜‚

    Frogurt (Frozen Yogurt) Flavour? I’m going to go with Frozen Custard (Frustard – lol!) because that’s very Las Vegas (OMG 😱 it’s 4/20 and you want to know my favourite flavours? I’m thinking the whole Menu!) 😁

    • Love me some Frustard too lol. To get my fix I usually go to Freddy’s Frozen Custard and Steakburgers so I can get a steakburger too. Mmmm, steakburgers πŸ™‚

      • justinmwat151

        πŸ’œ Freddy’s Frustard and Steakburgers (we have one in Henderson adjacent to Sunset Station Casino), talk about flavour selection (and it’s actually 4/20) πŸ˜€

  2. Is this a good time to admit I misread the title of this one as “Possum” Benzoate the first time I saw it… πŸ™‚

  3. “That’s Bad!”

  4. (“than”, not “then”)

    • My bad. In my defence, I did all my schooling in French until University.

      • So we should be lucky you didn’t write ensuite πŸ˜‰

      • Just thought I’d point it out since it was in your boilerplate header and being used every week πŸ˜‰

      • if it’s any consolation my brain runs its’ own autocorrect and I never noticed 😊
        It doesn’t help when I’m trying to proof-read my own content and I know what I meant to say, so that’s what I see more often than not, usually only spotting mistakes quite some time later when I’ve forgotten what I meant to type !!
