DailyDirt: How Long Can Food Last?
from the urls-we-dig-up dept
Preserving food in various ways has been a pretty important part of developing stable societies. Without a reliable food supply, it’s kind of hard to move forward and to do anything other than creating a stable food chain. But with modern food processing, food can last indefinitely… though it may have gone a bit too far. Here are just a few quick links on a how a few foods stand up to somewhat extreme conditions.
- There’s at least one Twinkie that lasted about 30 years with only a slight bit of mold growth. It’s been a few more years since the last story on it, so maybe the mold finally finished it off…. Anyone have an update? [url]
- Happy Meals seem to be happy for a pretty long time, too. It’s not like people *want* fast food to get moldy really quickly, but it’d be nice to find out which burger out there goes bad the fastest. (No cheating by humidifying them!) [url]
- A 20-day-old radish will last about 30 minutes in the vacuum of space — and still grow after returning to normal Earth conditions. Unprocessed foods seem to be pretty tough, too. [url]
- For best results, though, food flavors are usually fairly sensitive to temperature. Cold tomatoes and skunked beer are just a couple examples. [url]

By the way, StumbleUpon can also recommend some good Techdirt articles, too.

My own anecdotal experiences today
I just got done eating shrimp and was thinking how much it sucked. I grew up on the Gulf Coast but now live very far from any salt water. The stuff I ate probably came from Vietnam and of course was frozen.
Did it “last”? Well yes in the sense that I’m sure I’m not going to get sick from it but having grown up with fresh shrimp caught within a day or 2 of being served to me I would say it did not “last”.
Actually the non-rotting hamburger stories have been debunked.

It seems ANY burger that size left exposed to open air will not rot. Only thicker burgers with more moisture allow for mold or bacterial growth when left exposed to open air. And conversely even McDonald’s Happy Meal burgers will rot if placed in a container where the moisture is trapped. Presumably this also applies to humid environments in general and to other similarly sized burgers.
In other words, as stated in the Gizmodo article, “The scientific method! It’s a beautiful thing.”
PS. I am in no way endorsing McDonald’s food as good/healthy food. I do however endorse the scientific method with controls and the whole bit.
Re: Actually the non-rotting hamburger stories have been debunked.
Aha.. thanks for the experimental evidence. Nice to know that there’s nothing special about a Happy Meal…
But technically, it’s not debunked that the meal won’t rot… it just won’t rot under certain conditions… which is probably true of the Twinkie as well.
Re: Actually the non-rotting hamburger stories have been debunked.
This is partly why the cure to things like the common cold (and bacterial infections, etc…) is simply to open a window. A closed environment is a safe-haven for microorganisms and it makes it much much more difficult for your body to get rid of them as well.

(and the biggest reason why people get sick in the winter is because they tend to close their windows and doors to keep warm. That’s a no-no. If you want to avoid getting sick, don’t do it. Especially an insulated warm environment, you’re just begging to get sick.
That’s not to say hypothermia is not a potential risk (though it’s more of a problem for the elderly). You still don’t want your house to be freezing cold, you want it to be about room temperature, but living in a warm insulated environment is not good.

What? Very few germs are airborne; most are spread by touch. Opening a window won’t do anything. The reason there are more colds in the winter is because people are indoors and in close contact more.
Water Activity Is A Method Of Preservation
Twinkies and those hamburgers have low water activities, and without free water in those systems, microorganisms can’t grow. Jerky and fruit leather also have low water activities and won’t rot either, but those are “traditional” foods that we don’t think about…
Weird but true story;
Occasionally I get a bacon cheeseburger at a local diner. It’s served with lettuce and a tomato slice, but I prefer to eat the burger with just the cheese and bacon. I usually save the veggies and make a small salad the next day. A couple years ago, I forgot and left them in the Styrofoam container sitting on the counter for about 24 hours. It wasn’t especially hot in the house. When I opened it the next day, the tomato slice was PURPLE! I picked it up and it looked like it had ink dripping off it! I have no idea what they did to it, but something was definitely funky.
Also, two things you should never put in the microwave are English muffins and pizza. If you try to thaw frozen English muffins, they taste funny and have a different texture. If you heat leftover pizza the cheese loses its flavor.
Beer
Beer might not taste as good if it’s the wrong temperature, and it might go bad if it stays too warm, but that distinctive skunky flavour isn’t from heat, it’s from light–or UV, to be more precise. That’s why you should steer away from Corona and all those other beers that come in clear or even green bottles. Stick with brown bottles or cans, the beer will keep better. Also keep your beer in a dark place.
My beer never lasts long enough for it to care where it is being kept, it’s more worried about why it’s being beheaded.

What the heck is this? How does food preservation have anything to do with tech. Get this daily roundup crap off the site. We read Techdirt for the quality writing and insight, not to see this.
