McDonald's shows what's really inside a McRib

NEWYou can now listen to Fox News articles!

McDonald’s is tackling the sticky problem of the McRib in its new efforts to debunk the myths about the fast food chain’s food.

With the help of newly hired "MythBusters" co-host Grant Imahara, who recently kicked off a new campaign “Our Food. Your Questions” aimed at disproving Internet-fueled myths of pink slime and other gross rumors, a new video has been released that sets out to find out what’s really in the mysterious and elusive boneless pork sandwich.

It also recruited self-proclaimed McDonald’s skeptic, high school teacher Wes Bellamy, who tweeted out a picture of a vial looking frozen piece of McRib and tried to dissuade people from eating it when the image went viral last year.

Imahara and Bellamy flew out to Oklahoma City to visit to Lopez Foods, one of McDonald's U.S. pork suppliers, to get some answers from Lopez Vice President Kevin Nanke.

"The only thing in a McRib patty is pork, water, salt, dextrose -- which is a type of sugar -- and preservatives which are BHA, propyl gallate and citric acid which as used to lock in the flavor," Nanke explains in the video.

Nanke then shows Imahara and Bellamy the assembly machine that molds each patty into the iconic McRib shape that resembles a rack of ribs and flash-freezes it.

Bellamy, goes from skeptic to convert pretty quickly.  “This looks a lot different from a picture that I saw on Twitter,” he said. “So that’s how you keep it tasty like my Grandma’s barbecue!”

After the McRib is put together with the BBQ sauce marinade, pickles, onions and buns Imahara and Bellamy, who admit to never eating one before, dig into their McRib sandwiches, and seem to be satisfied in more ways than one.

"All of my questions have been answered," Bellamy says. "The sandwich is pretty good, man. It's actually really good."

There are two more videos:  One featuring a McDonald’s archivist who briefly explains where McRib came from, and another featuring a McDonald’s executive trying to explain why the McRib is seasonal.

While people have the feeling that they’re being taken behind the veil to get a sneak peek inside the production, it’s still just a clever marketing tool to present the McRib in the most palatable way possible.

And get ready for the roll out of others. McDonald’s working on the next “Our Food. Your Questions”--one for Chicken McNuggets and another on french fries.
