McDonald’s has released a promotional video that shows how its french fries are made. Liz Leslie gets to the nub:
“So yes, the fries are made of real potatoes, but they pick up a few additives on their way to the drive-thru window.
“Dextrose homogenizes the color of the fries, while sodium acid pyrophosphate keeps the color from graying once frozen. The potatoes are partially fried before making it to the restaurant in a combination of canola, soybean and hydrogenated soybean oils.
“Other additives –18 if you don’t count potatoes as an ingredient — keep the fries looking and tasting consistent, as Imahara explains in a companion video.”
