Everything canned in glass and metal cans can be eaten long after the expiration date, whereas in plastic bags (cereals, seeds, legumes) - they often acquire a chemical smell from the packaging even before the end of the shelf life. You can eat expired pasta - I tried such pasta with a one-year delay, there was no smell or taste (although they were in plastic packaging). Many sausages cannot be eaten after the end of the shelf life - since no matter how much chemistry is stored in them, some of them do not even live to the end of the term. Salt and sugar can be consumed almost forever. In cereals and in flour, worms also often start before the end of the shelf life. Same with spices. Chocolate can be consumed for a short time after the expiration date. For a very long time, frozen meat can be eaten after the end of the shelf life, of course, provided the temperature is maintained further.
Vodka! Well, in general, many alcohol do not have an expiration date as such. My husband just a couple of weeks ago drank a vodka of the same age, both 25 years old. Vodka is like vodka, he says, better than many now.
in principle, you can eat something that does not have moisture and liquid, but with canned food, I would not recommend taking risks and with products that have liquid from pickles to milk, it is better not to risk it
All products in the store have a longer shelf life than stated. How much exactly - you need to ask people working in the field of standardization and certification (I think).
If you just apply logic, the products have a guaranteed shelf life. Those. the time during which physical and chemical processes will definitely not turn the product into trash. Exceeding the expiration date increases the chances of product spoilage. If these are products, then it is obvious that the proportion of nutrients is gradually decreasing, and the proportion of garbage, harmful and even toxic substances increases. In addition, the product may also spoil the packaging. For example food varnish can dissolve or deteriorate. But this is theory.
Expired perishable is better not to eat. The situation is better with cereals and canned food. But still, a significant excess of the expiration date can be dangerous to health and life. Better not to risk it. We have not yet lived to see the time when your internal organs (if anything) will be replaced with new ones grown from your own cells. :)
Roughly speaking, any vegetable products (except canned meat, pickles, etc.) that have not changed their appearance and have not changed the smell and / or taste towards sour / dried / rotten / moldy. Dried up is also good. The main thing to be careful is to sort out cereals to check for bugs, cut fruits and vegetables, etc. And remember that almost no food covered with mold, like those that came into contact with it, are not edible, even if the mold can be cut / detach. Experimenting with strongly "chemical" or liquid opaque products is definitely not worth it, because you may simply not notice that something is wrong.
for some reason, no one mentioned smoked and salted foods. And also 140 characters, which always remain relevant and prevent you from giving short answers and clarifications
I will add my personal experience to all the previous answers. Tea (and coffee, probably) can be consumed even after the expiration date. A few months ago I was drinking Georgian tea, packaged back in 1987. Such a strong, tart taste, in my opinion, time has not greatly affected it.
You can also eat dairy products for the first few days, it won't get any worse. If you don't like the taste, you can add sugar, for example. I once found in my refrigerator a weekly expired cottage cheese, hence this invaluable experience.
I agree about salads with spices, I checked it myself.
In general, theoretically, you can eat any delay, if cooked properly. But still, if you are afraid for your weak stomach, it is better to refrain from such experiments.
Expired canned food is not scary to eat if the can is not dented or rusted. I'm telling you this as a person who ate a can of canned meat the day before yesterday, which was almost 20 years old ...
Soap can sit for decades and not deteriorate. I found 40-year-old glycerin and laundry soap at home - it was very dry, but it washes superbly))
Sugar and pasta. If they look good, it doesn't matter how old they are - you can eat! But cereals do not last long. They are found very quickly by flour beetles.
I didn't eat old pasta, but I drank tea with Soviet-made sugar. And you know what? Soviet sugar is sweeter than modern sugar ...
A grandmother died at the neighbors', after her there remained in the cellar twenty years ago stocks of jam (presumably currant) "for a rainy day". They ate all along the street, broke one spoon, bent four ... But the jam was very tasty, although it had to be sucked like caramel))
Expiration date is not just a number, the next day after which the product will lose its useful properties. With the expiration date, only the manufacturer's warranties expire. So, the first thing that comes to mind is alcohol. Also, sweets like jam - nothing will start in a large amount of sugar. There are also salads, where there are a lot of spices, like Korean - originally spices were used to increase the shelf life. For the same reason, chips can be included here.
In fact, there are more of them, you just have to look at the storage conditions.
