Why? Not trolling, just curious.

"Sorbic acid, or 2,4-hexadienoic acid, is a natural organic compound used as a food preservative". Therefore Potassium sorbate is a salt of sorbic acid with potassium.

We have a pretty good idea of what these chemicals do to say the least. Our body, assuming it even absorbs the chemical, either metabolises them into something useful or something it excretes, in the case of potassium sorbate this is mainly carbon dioxide and potassium. The body is more than capable of handling most organic compounds, it does not care or know if they are natural or artificial.You can read the safety report on potassium sorbate here.

As for acesulfame K, you can read what the NHS says about it and there's also a link to a safety report. Essentially the body absorbs it and excretes it unchanged rather quickly.

We can't assume everything that is natural is therefore safe and wholesome and every chemical, even though everything is made of chemicals, is artificial and/or dangerous. Formaldehyde is a class 1 carcinogen, it is proven to cause cancer and is a chemical used to preserve bodies and tissue samples. Sound like you might want to consider avoiding this chemical right? However, it's also perfectly natural and found in foods like pears but please don't stop eating pears!

Would you eat a product that contains, amongst other ingredients:

E160a, E300, E306, E101, E515, 2-hydroxy-3-methylethyl butanoate, aspartic acid, ethyl hexanoate?

If not, then I guess you won't be eating any more bananas. :wink:
