Every food has a shelf life, but there are 10 foods that last for 100 years, what are they?

Every ingredient has its own way of storage, and a better storage method can not only extend the shelf life of the ingredients.

More importantly, the taste of the ingredients is the same as the taste of freshness, so we should accumulate social experience in this area. Today, let's talk about ingredients that are easy to store.

1.Grains.

The so-called food crops.

That is, the rice, wheat flour that everyone eats.

This type of meal, this kind of meal is very easy to store. In particular, when they are placed in a plastic bag in a vacuum environment, they can be stored for a long time longer than the various warranties indicated on the bag.

The term will not affect for three or five years. Even during an anaerobic exercise.

In this state, grain crops such as flour or rice stored in vacuum packaging bags can be stored for more than 30 years.

2.Dry goods.

There are many items involved in dry goods knowledge, such as dried bamboo shoots, black fungus, dried mushrooms and other mushrooms that we usually see that have long been sun-dried.

There are also dried soybeans, black beans, small red beans, big black beans, vermicelli, jujubes, etc., because these dry goods knowledge has passed the drying treatment method, so they have a very long shelf life, so as long as they are put in the shade, shelter from the wind and rain, and at room temperature, it is not a problem to put them in for three or five years.

3.Seasoning.

When cooking, you need to put all kinds of seasonings, such as salt, oil, sugar, etc., in fact, they have a very long shelf life, Aquarius.

Some of the above shelf life is only a limited time, in fact, it is much higher than this shelf life, and can even be stored for a long time. Put the seasoning in a cool, naturally ventilated, cool and dry place for a long time.

4.Sausages and bacon.

Sausage bacon is a marinated meat unique to the Chinese, which can be directly salted and then blow dried. The production process of sausage bacon itself can improve the storage time of braised pork, especially smoked sausage bacon, which only needs to be stored to avoid some humid environments, and some can even be eaten for more than ten years or decades.

The foods recommended above are very easy to store, and they are very easy to store, whether they are put in the refrigerator or at room temperature. Therefore, if you often have to stock up on some ingredients that are easy to store and want to store for a long time, then these ingredients are still very good.

Rice has a long shelf life, especially white rice, jasmine rice, etc. White rice can last for more than 30 years, and possibly even indefinitely.

Honey, which is high in sugar, is one of the most legendary foods. Honey has a long shelf life and crystallizes when it's cold. It is stored in plastic bottles and glass bottles, and as long as it does not come into contact with raw water, it can still be used safely even if it is stored for 100 or 200 years.

There are many foods with a long shelf life in our lives, such as rice, honey, balsamic vinegar, and liquor. The longer the better. As long as it is properly stored, it will generally not deteriorate.

First, salt, soy sauce and other seasonings.

Oil, salt, sauce and vinegar are indispensable seasonings in the kitchen, such as vegetable oil, soy sauce, vinegar, salt, sugar, honey, these seasonings, the shelf life is relatively long, and as long as the salt, sugar, and honey are stored properly, it stands to reason that they can be kept for several years without deterioration, and some need to be prepared at home.

Second, rice, white flour and various grains.

Rice and white flour are indispensable staple foods in the daily life of Chinese people, and they are naturally indispensable, but when buying, try to buy small vacuum-sealed bags, eat a bag, open a bag, and avoid insects and deterioration due to improper storage. You can also stock up on cereals, make multigrain porridge and multigrain rice to increase some nutrients, and like soybeans, you can also make homemade tofu and soy milk, which can solve the urgent need.

Third, dried fungus, shiitake mushrooms, yuba and other dry goods.

Mushrooms have high nutritional value, such as shiitake mushrooms, hazel mushrooms, fungus, white fungus, daylily, etc., pay attention to store them in a cool and ventilated place, and it is no problem to keep them for 1 year. There are also dried vegetables such as dried beans, dried eggplant, dried radish, etc., which are easy to preserve and do not occupy the refrigerator space.

Fourth, canned luncheon meat, fish, dried noodles and other food.

There are many foods that can be canned, such as luncheon meat, braised pork and various kinds of canned fish, as well as canned fruits such as yellow peaches, hawthorns, and oranges. Canned food is processed by processing, canning, sealing, sterilization and other procedures, and can be stored for a long time at room temperature, and it is also very convenient to eat.

Fifth, Chinese cabbage, radish and other vegetables that are good to store.

There are many shelf-stable vegetables, such as Northeast people will store Chinese cabbage, radish, potatoes in winter, as well as pumpkin, onions, yams, carrots, etc., these are vegetables that can be stored for a long time without putting them in the refrigerator.

Foods with a shelf life of more than 10 years:

1.Solid sugar: Solid sugar includes commonly used white sugar, cotton sugar, rock sugar, single crystal rock sugar, etc.

Due to the low amount of moisture and strong osmotic pressure in the structure, solid sugar is not conducive to the growth of microorganisms and is difficult to be polluted. Sugar is also often used to preserve foods, such as candied fruits, preserved fruits, etc. However, sugar is easy to absorb moisture, and if it is not placed properly and its properties change, it will be contaminated by microorganisms.

2.Salt: The main ingredient of table salt is sodium chloride, which is chemically very stable.

Like table sugar, table salt is often used to preserve food and is a natural preservative. However, if the iodized salt we often eat, if it is not protected from light and high temperature, the iodine content will be reduced if it is left for too long, but the salt quality will not change.

3.Vinegar: Vinegar has the effect of antibacterial and sterilization, and can be used for food preservation and preservative, such as acid stains. The shelf life of vinegar is relatively long, but it is also affected by the process and raw materials. The brewing vinegar with better technology is sealed in a jar and placed underground, and the longer the year, the more mellow the taste.

4.Honey: Fresh and ripe honey, a transparent or translucent gelatinous viscous liquid, sugar accounts for more than 3 4 of the total amount of honey, the water content is small, bacteria and yeast cannot survive in honey.

In addition, bacteriostats are also contained in honey. Therefore, ripe honey is not easy to spoil if left for a longer time. However, if it is not mature honey or an inferior product that has been mixed with water, it will ferment and bubble after a period of time, turn sour, and cannot be eaten.

Under sealed conditions, microorganisms are not easily invaded and difficult to multiply, so they will never deteriorate. However, this does not mean that the longer the liquor is stored, the better, and the taste of ordinary flavor liquor will become weaker and the aroma will weaken after 5 years; Sauce-flavored aged wine is a good wine, while it is still inconclusive whether a strong wine that has been stored for many years is a good wine.

1. Salt: In addition to not rotting, salt can also help other foods to preserv, such as the hamburger that has existed for more than ten years.

The reason why it lasts so long is not because of its preservatives.

The content exceeds the standard, but because its sodium is salt, the content is super high, so that it has its own antiseptic function.

2. Tangerine peel: When I was a child, I would meet tangerine peel every time I came to Xinhui.

When the orange harvest is abundant, they will help the elders to make tangerine peel together, from peeling the pulp to putting it in the sun ......I still remember that at that time, tangerine peel that was more than 10 years old was only sold for dozens of yuan a catty, and the high-quality tangerine peel that was more than 10 years old was as high as thousands of yuan a catty, and it has been**. The owners of some tea estates have also begun to join the ranks of collecting tangerine peels, and there is also such a saying that the gold of tangerine peels will not be changed for a hundred years.

3. Aged vinegar: vinegar is a common seasoning in life, especially in the north, it will be particularly popular, and vinegar will be used when eating dumplings or cooking noodles.

As a seasoning, the taste is very appetizing, and vinegar is very helpful to the body, which can strengthen the blood vessels and promote metabolism. In fact, vinegar can be stored for a long time, but there is no expiration date.

The longer the vinegar is left, the more fragrant it is, and the more valuable such vinegar is.

4. Liquor: There are many liquor brands in China, and just like tea, the older the tea fragrance will be, and the ** of the wine will be higher, I believe that many people know, people who like to eat liquor know that good liquor can smell a wine fragrance as long as you open the bottle cap, so many people will look at the year when buying liquor, the longer the wine, the more fragrant the wine, and the liquor has no expiration date, as long as you don't open the lid, you can keep it there.

The above four foods have no expiration date, and as long as they are stored well, the longer they are placed, the purer the fragrance will be, and they can be eaten for a long time, without worrying about expiring or harming the body.

20 years? Canned food doesn't have this expiration date...

Which foods have no expiration date, the longer they are left, the higher the nutritional value.

As temperatures climb and microbes become more active, so does the risk of food spoilage, especially protein-rich ones. Food spoilage often has some signals, mainly reflected in color, shape, smell, taste and other aspects.

Bean curd. After metamorphosis, it is dark gray, dark yellow or reddish-brown; The block shape is incomplete, and the tissue structure is rough and loose; The surface is sticky, easy to break due to touch, and inelastic; There is a bad smell such as rancidity.

Livestock and poultry meat. After deterioration, the flesh is dark in color, and the fat lacks luster; Extremely dry or sticky appearance, slow or incomplete recovery of depression after acupressure; There is an ammonia or sour taste, and even a foul smell.

Fish. After deterioration, the eyeball is flat or sunken, and the cornea is cloudy; The scales are incomplete, easily peel off, fade, blacken, and their edges are dry; gill filaments adhesion; The abdomen is distended, and the muscles are loose and elastic; There is a fishy smell.

Milk. After metamorphosis, it is light pink or distinctly yellowish-green, or grayish in color; It is a viscous and uneven solution, with dense clots or flocculents; There is a distinct odor.

Eggs. After deterioration, the eggshell is gray-black or has spots and cracks; Feel light and fluttering, shake it, you can clearly feel the egg yolk shaking; Opaque or grayish-brown shades when the light is seen through; It is common to open to sticky shells or yellowing.

In addition, carbohydrate-rich foods such as grains, vegetables, fruits, sugars and their products will have a sour, alcoholic or musty taste after spoiling; Oil-rich foods such as vegetable oil, lard, butter, cream, nuts, and fried foods will have a hala flavor when they go bad.

In my middle and high school chemistry classes, I was exposed to ammonia, and it smelled very bad, like a toilet that hadn't been cleaned for a long time. If some fish, shrimp and seafood products are left out for too long, these special smells will be produced. This is due to the fact that seafood such as fish and shrimp are rich in protein.

When these proteins are broken down, they produce amines and may even produce small amounts of ammonia. These substances volatilize in large quantities, producing a strong pungent taste. If the seafood product has such a taste, it proves that the seafood is very toxic, even if it is expensive, it must be thrown away immediately, and it must not be eaten.

4 tips for telling if your food has gone bad.

Food spoilage generally refers to the fact that under certain environmental factors, the food loses its original nutritional value, tissue characteristics, color and flavor due to the action of microorganisms, and is transformed into food that does not meet the requirements of hygiene. Such as: rancid fish and meat, rotten fruits and vegetables, rancidity of oil, mildew of grain, etc.

The deterioration of fruits and other fruits is mainly due to surface rot, some watermelons and other foods will become rancid, and pastries such as bread are mainly moldy, and if they are left for a long time, they will be drawn.

Moldy, smelly, sour, and smelly.

In the "Regulations on the Administration of Food Labeling" issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, there are four types of food that can be "exempted from labeling the expiration date", namely beverages with an alcohol content of 10% or more, vinegar, edible salt and solid sugar.

Therefore, the exemption from the expiration date of the label will not endanger everyone's health. The same is true for edible vinegar, edible salt and solid sugar, these foods are stable at room temperature, vinegar also contains acetic acid, edible salt and solid sugar have high osmotic pressure, plus there are no other nutrients, and it is difficult for general microorganisms to multiply.

Does something that has no expiration date exist?

It is possible that many people are thinking that even emotions, lives, values, etc. have a certain expiration date, is there really something that has no expiration date? The answer is yes. First of all, these things can be found everywhere around you, and some careful people have already discovered them.

Salt, for example. Speaking of which, many people may have to ask, does the edible salt in the supermarket have no expiration date? Of course, you are very careful, some of the edible salt in the supermarket is marked with an expiration date, but that expiration date is only the expiration date of the additives.

According to the national standard, salt can not be marked with the expiration date! In other words, there is no so-called expiration date for salt without additives!

After talking about salt, the next one is also familiar to you. That is liquor, to be exact, liquor with an alcohol content of more than 10%. Liquor with an alcohol content of more than 10% has no expiration date, and everyone knows that the longer the liquor, the better.

The ** of old sake is also much higher than that of new sake! It is possible that the alcohol content will decrease due to the storage time being too long, but the wine will only become more fragrant with the wine intact. Of course, any liquor is spicy!

There is another item that everyone often uses in their lives, and that is honey. Well-ripened honey is a transparent or translucent gelatinous viscous liquid, and the sugar content accounts for more than 80% of the total amount of honey, because the content of water in honey is very small, the bacteria and yeasts that cause spoilage and spoilage cannot survive in honey. In addition to this, honey also contains bacteriostats.

This makes it even more difficult for bacteria to survive in honey! Therefore, ripe honey is not easy to spoil if left for a longer time. However, if it is not mature honey or an inferior product that has been mixed with water, it will ferment and bubble and become sour under the action of bacteria after a period of time.

Of course, one of the home seasonings also has no expiration date! That's vinegar, and certainly not the vinegar that we commonly use in our families. Vinegar commonly used in the family is generally marked with an expiration date, and the shelf life is about two years.

According to the requirements of China's "Food Labeling Management Regulations", four types of food can be exempted from the standard shelf life, namely beverage wine, vinegar, edible salt, and solid sugar with an ethanol content of more than 10%. Since the national standard stipulates why vinegar generally has a shelf life and wine does not, the reason for this problem is that this is determined according to the process and acidity, generally the acidity is above the degree, most of them are brewed vinegar, not blended. Even if this kind of aged vinegar does not add any preservatives, it can be stored for a long time without spoiling, and there is generally no need to mark the expiration date!

The last item I know of is sugar! Due to the unique structure of sugar, in principle, it is possible to have no expiration date! Of course, there is still a lot that I don't know, and everyone is welcome to add, and if there is a mistake, everyone is welcome to correct!
