Next time you feel compelled to clean out the pantry, don't feel bad about putting it off.
A lot of the old food that's gone beyond the manufacturer's expiration date could still be edible for years or decades longer.
Such are the findings of food science researchers who recently subjected a panel of human tasters to samples of really old food. They discovered that artifacts like 20-year-old dried milk and 28-year-old rolled oats were still perfectly edible and sometimes even tasted OK.
"You'd think that shelf life would be much shorter," said Oscar Pike, one of the professors of food science at Brigham Young University who conducted the study. "But that's not the case."
Food scientists have long maintained that certain foodstuffs, like salt, granulated crystal sugar and wheat kernels, can be stored indefinitely at room temperature or below. But Pike said he was uncertain whether a more processed grain, such as a rolled oat, would also stand the test of time.
To find out, researchers prepared oatmeal from 16 samples of regular and quick-cooking rolled oats that had been stored up to 28 years in sealed containers. A panel of tasters rated the oats on aroma, texture, flavor, aftertaste and overall acceptability. Scientists also analyzed the samples' nutritional quality.
The conclusion? Tasters rated the quality of the old oats from 4.8 to 6.7 on an ascending scale from 1 to 9. Three-fourths considered them acceptable in an emergency.
Makers of long-lasting food products aren't surprised that people weren't keen on the taste of 1970s oatmeal.
"Palatability will decline before edibility vanishes," said Gary Hansen, owner of Pleasant Hill Grain, which sells food packages for emergency stockpiling.
Properly stored food, Hansen noted, can be edible longer than one might infer from manufacturers' expiration dates, which typically indicate when a product starts to taste worse or lose some nutritional value.
Hansen said he's seen rising interest in emergency preparedness in the wake of Hurricane Katrina. But while the retailer's most popular package -- a supply of dehydrated food to feed one person for a year -- is selling well, customers' level of concern is much lower than in 1999. Then, Americans stockpiled massive quantities in anticipation of a Y2K disaster.
Ted Labuza, a food science and engineering professor at the University of Minnesota, said research has shown that seeds can last for thousands of years if they're not damaged. Processing and improper storage practices that expose items to heat or oxygen are what cause deterioration.
"I've had canned chicken that was stored in a military case for seven years," Labuza recalled. "It was still very edible."
Pike said there are myriad reasons for ultra-long-term food storage, including maintaining surplus food stocks for humanitarian aid or national emergencies. He also doesn't discount the likelihood of individuals keeping stockpiles for years or decades.
In some cases, they already are. To get samples for edibility testing, Brigham Young researchers put an ad in the LDS Church News, a Mormon publication, asking for donations of old packaged food that had been stored under stable conditions. Pike said he chose the periodical for soliciting donations because the church advises members to store a year's supply of food in preparation for hard times.
But even he was surprised to receive samples decades old and still in good condition.
"It's really unique to have food around that long," he said.

The oldest food I've ever *seen* but did not dare touch... oh, stuff that the Dirt Queen had had mouldering in her kitchen since the 1980's. (This was in 2002, mind you.)

I work with a food pantry too. We have a 22 year old twinkie enshrined in the "Food Donation Hall of Shame". Lots of other great, old food there too.

I have an opened bottle of tomato juice that I took home from my brother's birthday party in Sept '01 (the Saturday before 9/11!) and I sniff it now and then and it seems OK, but I'm just not a tomato juice guy.
I have a bottle of lime juice (Gimlet style, no pulp) that I bought at least 25 years ago. I used in once when I bought it, but otherwise it's the same story as the tomato juice.
I heard once that 3000+ year old honey discovered in Egyptian tombs is still edible.

Husband eats 50-year-old chicken
A man celebrated his golden wedding anniversary by eating a 50-year-old tin of chicken.
Les and Beryl Lailey, of Denton, Gtr Manchester, were given the chicken in a hamper on their wedding day in 1956.
The Buxted Chicken tin remained in their kitchen cupboard until the couple marked 50 years together this month.
"We kept it safe, and I always said 'on my 50th wedding anniversary I'm going to eat that chicken' - so I did," said former soldier, Mr Lailey, aged 73.
"When we got married I'd just come out of the Army and we had very little money, so we did our own buffet.
"We got a hamper as a present and included in it was this whole chicken in a tin. We didn't use it and packed it away and kept it."
Tight vacuum
Mr Lailey, a former soldier, said he had not felt ill since eating the chicken.
The couple were given the chicken on their wedding day
The pair met at an Irish pub in Hulme, Manchester.
"I had to go back to the Army almost straight after we met, but we kept in touch by writing letters. I came home and we got married," Mr Lailey added.
Prof Eunice Taylor, a food safety expert at the University of Salford, said: "Canned food can last indefinitely if it has been sealed properly, although the normal shelf life is about six months.
"If it's done at high temperatures and under high pressure, then the process should create a tight vacuum.
"If anyone is going to eat old canned food, I would suggest they heat it thoroughly first of all, just in case to be extra safe."

Man, it makes SO MUCH SENSE that BYU would do a study on the edibility of really old, not particularly good food such as rolled oats. LDS Chruch asks its members to keep a year's supply of food, consequently a lot of houses in the area have giant pantries.
My parents are super cheap-o and I found out a few years ago that all the holiday candy at Easter, Xmas, etc., my parents had bought the year previous at post-holiday clearence and saved it for the next year's Easter baskets of Xmas stockings. So jellybeans feel obscenely soft and chewy to me now, becuase they're not over a year old when you buy them at the store.
My grandma's even more of a cheapo and I know I've eaten boxes of Rice-A-Roni or Cheerios that were half as old as I am.

These scientists had 400 year old clam! Nom nom & so on!

(Srsly though. They only discovered it was 400 years old after they killed it...)

Haha wanted to say something AGAIN about BYU guy. Have fun eating your 20-year-old oats, buddyboy.
