Do instant potatoes go bad?


Registered User
So I'm rooting around the pantry for some ranch dressing (Neuman's of course) for my chicken bits and came across a box of instant mash potatoes that is open and probably 6 to 9 months old. the flakes looked fine and their were no bugs so I cooked some up.

As you can see it all looks normal. The right consistency and all. (the yellow tint is because I like to throw in a lot of butter)

But it taste off. It's that "you can't quite tell if its you or if it really taste funny" kinda taste if that makes sense.

So does this shit go bad? Am I going to have a tummy ache the rest of the day?


What's black and white and red all over?
I thought they started out bad.

Of course, the guy from Idaho has to chime in about potatoes. You are no better than DTT. :action-sm

I bring love and cheer.

Buy a bag of potatoes you savages. Boil them on medium in milk in a nonstick pot for 10 minutes in slices and smash up with butter and salt/pepper.

Don't ever buy those boxes of garbage.

See any dried flakes helping mankind here? Didn't think so.

Potatoes help Wi-Fi: Boeing engineers use spuds to improve Wi-Fi

This 2006 photo provided by Boeing Co. shows early dielectric substitution testing using potatoes in an airplane in Arizona. Boeing has developed an advanced method to test wireless signals in airplane cabins, making it possible for passengers to enjoy more reliable connectivity when using networked personal electronic devices in the air. Employing an odd mix of the low-tech and the high-tech, Boeing loaded a plane with sacks of potatoes as part of testing it did to eliminate weak spots in in-flight wireless signals. Engineers determined radio waves bounce off the spuds much the same way they do with human bodies. Thus, the aircraft maker’s researchers were able to spare people from having to sit motionless for many hours while data was collected. (AP)
If the wireless Internet connection during your holiday flight seems more reliable than it used to, you could have the humble potato to thank.

While major airlines offer in-flight Wi-Fi on many flights, the signal strength can be spotty. Airlines and aircraft makers have been striving to improve this with the growing use of wireless devices and the number of people who don't want to be disconnected, even 35,000 feet up.

Engineers at Chicago-based Boeing Co. used sacks of potatoes as stand-ins for passengers as they worked to eliminate weak spots in in-flight wireless signals. They needed full planes to get accurate results during signal testing, but they couldn't ask people to sit motionless for days while data was gathered.

“That’s where potatoes come into the picture,” Boeing spokesman Adam Tischler said.

It turns out that potatoes – because of their water content and chemistry – absorb and reflect radio wave signals much the same way as the human body does, making them suitable substitutes for airline passengers.

“It’s a testament to the ingenuity of these engineers. They didn’t go in with potatoes as the plan,” Tischler said.

Recapping the serendipitous path that led to better onboard wireless, Tischler said a member of the research team stumbled across an article in the Journal of Food Science describing research in which 15 vegetables and fruits were evaluated for their dielectric properties, or the way they transmit electric force without conduction.

Its conclusions led the Boeing researchers to wonder if potatoes might serve just as well as humans during their own signal testing. Despite some skepticism, they ended up buying 20,000 pounds of them.

Video and photos of the work, which started in 2006, show a decommissioned airplane loaded with row upon row of potato sacks that look like large, lumpy passengers. The sacks sit eerily still in the seats as the engineers collect data on the strength of wireless signals in various spots.

The Boeing engineers added some complicated statistical analysis and the result was a proprietary system for fine tuning Internet signals so they would be strong and reliable wherever a laptop was used on a plane.

Boeing says the system also ensures Wi-Fi signals won't interfere with the plane's sensitive navigation and communications equipment.

“From a safety standpoint, you want to know what the peak signals are, what’s the strongest signal one of our communications and navigation systems might see from a laptop or 150 laptops or 350 laptops,” Boeing engineer Dennis Lewis explains in a video.

In a nod to the humor in using a tuber to solve a high-tech problem, researchers dubbed the project Synthetic Personnel Using Dialectic Substitution, or SPUDS.

The company says better Wi-Fi signals can be found already on three Boeing aircraft models flown by major airlines: 777, 747-8 and the 787 Dreamliner.


Lingering longer for a longering linger
I can't see how instant potatoe flakes can go bad...maybe they get stale after awhile? And yes, definatly the bug thing. Gotta check for those if the box is really old.

They can't rot if you keep them dry, but they will absorb the stink of your house over time.
How bad were they?


as a matter of fact i dont have 5$
ooooooo science!!!!!!!!!!!!!!!!!!!!!!!!!! the potato's didn't go "bad" they started to oxidize in the package,it changes the proteins slightly and causes the "off taste" associated with freeze dried and even regularly dried foods over time. its one of the side effects of the drying process. one night while i was wearing my tinfoil hat and preparing for the end of the world i did an extensive amount of research on "shelf stable" foods all of them from dried legumes, MRE's and basically anything that i could eat when the zombies take over the earth. the most stable things i could find are the legumes but the freeze dried foods are good for 20years, so are the MRE's but over time they oxidize and just start to taste nasty, still healthy still "ok" to eat, but just taste like shit. opening the packages speeds up the process buy exposing them to O2


Lying causes cat piss smell.
The LDS cannery folks, where I get my instant potato pearls, recommends less than 5 years on a sealed package. They are meant for longer term food storage, so more care is taken in their manufacture. I would imagine that run of the mill potato flakes out of a box would last significantly less since they are not specifically made for longer term storage.

Apparently they last longer than the OP.
