McDonald’s fries contain a petroleum-based chemical and a form of silicone found in Silly Putty, according to an experiment by a former Mythbusters host. During show host Grant Imahara’s investigation into the McDonald’s chain’s potato processing plant in Idaho, dimethylpolysiloxane is found in the tasty American fast food favorite.
Dimethylpolysiloxane is reportedly one of the prime ingredients not just McDonald’s French fries, but in Silly Putt as well. The petroleum-based chemical known as TBHQ is also part of the McDonald’s fries recipe, according to the former Mythbusters host. Grant Imahara also discovered that the fries are fried twice, once at the chain’s potato processing plant and again at restaurants.
“Potatoes, thank goodness! That’s a good start,” Imahara said before he went on to cite the other 14 ingredients in McDonald’s French fries.
The former Mythbusters host goes on to tell viewers that the TBHQ, dimethylpolysiloxane, and other ingredients used in the popular French fry recipe are safe for human consumption and used for good reason.
