If you’re like most people in the world you probably enjoy your food. And if you’ve been with us for a while you know people can enjoy some strange things. But this isn’t about strange food. This about strange ingredients. From beaver secretions to duck feathers, these are the 25 of the strangest ingredients found in your food.

Carmine
Basically anything with red coloring contains ground up, carmine filled abdomens from bugs that were most likely killed by immersion in hot water.

AKA calf stomach; this stuff is used to make cheese.
Coal tar
Number 199 on the United Nations list of most dangerous goods, it was once a very common source of red food coloring.

Polydimethylsiloxane

Xanthan Gum

Gelatin

Potassium Bromate

MSG
While most people know there is MSG in their Chinese takeout they don’t know why. It’s actually there to enhance flavor. MSG does have a flavor of its own as well. It is known as “umami” and interestingly enough has been claimed to be the 5th major taste (sweet, sour, salty, and bitter being the other four).
Lanolin

Ammonium Sulfate
If a little bit of fertilizer got through to our food that would be understandable, but this stuff is basically poured into bread dough by the gallon. Why? It makes the yeast more consistent. Oh yea, it’s also flame retardant. At least you can’t burn the bread, right?

Carrageenan
It is made of seaweed and is used as a vegetarian alternative to gelatin.
High Fructose Corn Syrup
While it may not be too strange that it is in your food, the fact that it has nearly replaced sugar as the primary sweetener in the Western Hemisphere is a bit mind boggling.
BHT

Silicone Dioxide
It’s often used in restaurants as an anti caking agent for making chili, you may recal the more common name of this substance from high school chemistry class – sand.
