Mountain Dew could dissolve a mouse

Mountain Dew offers odd defense in mouse charge

An attempt to win a small court battle this week has put Mountain Dew in peril of losing a much larger war.

PepsiCo, the soft drink’s parent company, defended itself against a man who claimed he found a dead mouse in a can of the citrus soda. Experts called in by PepsiCo’s lawyers offered a stomach-churning explanation for why it couldn’t be true: the Mountain Dew would have dissolved the mouse, turning it into a “jelly-like substance,” had it been in the can of fluid from the time of its bottling until the day the plaintiff opened it, 15 months later.

Forget legal disputes over canned vermin. The new question has become: Is Mountain Dew really so corrosive that it can dissolve a mouse carcass? And if so, what does it do to your teeth and intestines? Is Mountain Dew’s classic slogan — “It’ll tickle yore innards” — the world’s most sickening understatement?

Key to Pepsi’s legal argument is that there’s no chance a mouse’s corpse could survive, intact, for 15 months swimming in Mountain Dew.  While published studies have not been conducted on how rapidly Mountain Dew would dissolve a mouse, there is plenty of evidence to suggest that the neon green soda can eat away teeth and bones in a matter of months, and would likely do quite a number on a rodent.

“I think it is plausible that it could dissolve a mouse in a few months,” said Yan-Fang Ren of the University of Rochester School of Medicine and Dentistry, who has studied the effects of citric acid on bones and teeth. “But dissolving [the mouse] does not mean it will disappear, because you’ll still have the collagen and the soft tissue part. It will be like rubber.”

According to Ren, Mountain Dew contains citric acid, a substance naturally found in citrus fruits that exists as a powder in its purified, industrialized form. Most citrus sodas mix in the stuff to give drinks their tangy bite, while most colas, such as Coca Cola and Pepsi, incorporate phosphoric acid for the same effect. Consequently, these drinks have a low pH value around 3 (very acidic). Coca Cola, with its dark coloring and non-fruity flavor, may be the soft drink most often compared to battery acid, but in 2004, a well-known study led by dentist J. Anthony von Fraunhofer found that citrus sodas like Mountain Dew and Sprite erode tooth enamel around six times faster than colas. [ How Long Do Mafia Victims Take to Dissolve In Acid?]

When Fraunhofer’s team soaked human molars in Mountain Dew for two weeks (a period of time comparable to approximately 13 years of normal beverage exposure, the researchers calculated) the molars’ enamel lost more than 6 percent of its volume. Meanwhile, molars soaked in Coca Cola for two weeks lost slightly more than 1 percent of their enamel volume. (As a side note, “Diet” labels won’t shield your teeth from the damage: In the study, Diet Mountain Dew eroded more than 8 percent of the tooth enamel in the course of two weeks.)
