What foods have a long shelf life and how? Thank you

Foods high in sugar and salt can be stored at room temperature.

The salt content is high! If you think about it, pickled foods and the like, and there are low temperatures, and simplicity is not simple.

Hamburger! It's not bad for a few months.

Foods with a long shelf life and a long storage time are: honey, soy sauce, edible salt, rock sugar, tangerine peel, etc.

1. Honey. Honey is a supersaturated solution of sugar, which crystallizes at low temperatures, glucose is the one that crystallizes, and fructose is the part that does not.

2. Soy sauce. Soy sauce is a traditional Chinese condiment, a liquid condiment brewed with soybeans or defatted soybeans or black beans, wheat or bran, adding water and salt.

3. Edible salt.

Edible salt refers to processed edible salt with sodium chloride as the main ingredient obtained from seawater, underground rock (mineral) salt sediments, and natural brine (salt) water, excluding low-sodium salt.

4. Rock sugar. Rock sugar is an ice cube-like crystal made of white sugar decoction, which is a large-grain crystalline sugar prepared by recrystallization after redissolution and cleaning treatment by adding sucrose and protein raw material formula, with two kinds of single crystal and polycrystalline, which are transparent or translucent.

5. Tangerine peel. Tangerine peel is the dried ripe peel of the rutaceae plant citrusreticulatablanco and its cultivated variety. The medicinal herbs are divided into "tangerine peel" and "guangchen peel". Ripe fruits are picked, peeled, and dried in the sun or at low temperatures.

Rice and flour these staple foods are very easy to store, especially now vacuum bag packaging, the actual edible period is far beyond the time limit indicated on the packaging bag, three or five years will not affect the edible, bulk rice, pay attention to prevent "rice worms", put in the jar sealed, put a few cloves of garlic and some peppercorns, or the north can be put outdoors in winter to freeze overnight, can be a good long-term preservation.

2. Legumes. Red beans, mung beans, soybeans and other bean ingredients, rich in nutrition, superior taste, high protein and fat content, even as the main food can be eaten, the storage conditions only need to be dry and ventilated, to prevent germination, the storage time is several years.

3. Condiments.

Condiments such as salt, sugar, and oil contain a large number of essential elements for the human body, and some have a shelf life of nearly infinite time. Salt is the king of all flavors, and as a mineral in its own right, it can be stored for an infinite period of time, regardless of the environment, both dry and wet. Condiments such as soy sauce are fermented, and long-term storage can improve the taste.

Sugars are the main energy required by people, ordinary white sugar, keep it ventilated and dry, and store it for more than 10 years is no problem. Liquid edible oil will not deteriorate after 1-2 years of storage in a sealed environment, and solid butter and lard can be stored for a longer time.

Fourth, bacon meat.

Bacon itself is produced to improve the storage time of meat, especially smoked bacon, as long as it is stored properly and prevents a humid environment, it can still be eaten for several years or even more than ten years.

5. Dry goods.

Dried red dates, vermicelli, dried shiitake mushrooms, yuba and other dried goods, as long as they can be kept dry or sealed in a storage environment, it is difficult to deteriorate, and they can still be eaten normally after several years.

6. Canned food.

At the beginning of the design of canned goods, it was to solve the problems of seafarers on the ship and the imbalance of food storage and nutrition during the period of marching war. It is a food that can be stored for a long time, and it is very rich in variety and taste, fruits, luncheon meat, fish and even vegetables can be used as ingredients in canned food, and the shelf life ranges from 1 to 5 years.

7. Alcohol. Liquor is brewed from grain, is an ancient drink, liquor is high in calories, can be used as a cold food, beer, wine, rice wine and other nutritious, with a variety of nutrients. As long as the high-grade liquor is well sealed and stored for an extremely long time, there is no problem in storing it for decades.

8. Honey. Honey is a very special food, the main ingredients are all kinds of monosaccharide glucose, fructose, etc., in addition to all kinds of vitamins and, minerals, amino acids, can provide a lot of nutrients to the human body, honey is not suitable for microbial parasitism, has antibacterial effect, some archaeological sites, even found two or three thousand years ago honey jar honey can still be eaten, but when buying, we must pay attention to the purchase of real honey, not honey products.

Foods that can be stored for a long time include: canned food, honey, bacon, rice, beef jerky, compressed biscuits, and baked naan.

Honey, ripe honey, is a transparent or translucent gelatinous viscous liquid, with sugars accounting for more than 3 4 of the total amount of honey, and also contains bacteriostats. Neither bacteria nor yeast can survive in honey. It can be stored for a long time.

Honey, liquor, vinegar, sugar, and salt are the five food items that have the longest shelf life. Most of them are foods that contain no water or very little water. According to the national food management regulations, four types of food can be "exempted from labeling the expiration date", and beverages with an alcohol content of 10% or more, vinegar, edible salt and solid sugar.

When the alcohol content exceeds 10% (such as liquor and most wines), the growth of microorganisms is completely inhibited and it does not go bad. The same is true for vinegar. Salt and solid sugar have a very high osmotic pressure, so microorganisms such as bacteria cannot grow and do not deteriorate.

There are many foods that can be stored for a long time, and the main ones are as follows:

1. Alcohol, the national standard stipulates that the alcohol content of alcohol exceeds the specified concentration without marking the shelf life, so unless it is volatilized cleanly, it can be stored all the time.

2. Cured meats, such as salted pork, bacon, sausages, etc., can be prevented for a long time due to their high salt content and low moisture.

3. Due to the low water content of various teas, they can basically be stored for more than 3 years.

Good evening. Food products can be stored for a long time at low temperatures, so it is right to keep them in the refrigerator.

Also, when purchasing, it is necessary to be appropriate, and do not buy too much food at one time, which is not conducive to preserving the freshness of the food.

It can be stored for a long time and can be opened directly to eat. Canned food meets the above two conditions, that is, it can be stored for a long time, and it can be eaten directly. The invention of canned food was a revolution in food preservation, he solved the problem of people storing fruits, vegetables and meat, and provided great convenience to our lives.

Therefore, the food that can be stored for a long time and eaten immediately after opening is canned.

Rice can indeed be stored for a long time, but if the rice is eaten by mice, then the rice is gone all at once. Any food can last for a long time, and as long as you don't throw it around, it can probably last for a long time. Be mindful of food.

If it is stored for a long time, then such items need to have good storage, such as rice, which can be stored for a long time, and can be stored for several years in dry conditions.

Fungus, vermicelli, dried vegetables and other foods can be stored for a long time, and have nutritional value and preservation value.

If the food is stored for a long time, it must be treated by a special process, for example, smoked bacon, he will put it for several years, there will be no problem, under normal circumstances, ham sausage, its shelf life is still relatively long.

One is honey, which can be stored for a long time as long as it is in a sealed glass bottle. High liquor, Pu'er tea.

I remember when I was a child, in late autumn and early winter, my family would store a lot of Chinese cabbage, radish, potatoes and other vegetables, put them in the vegetable cellar, and also store the rice and corn grown in my own field, as well as dried vegetables and mushrooms in summer, so that even if it snows heavily in winter, I don't have to go out to buy vegetables, and I can eat for a month.

The problem is this, the food that has been stored for a long time is milk powder, compressed biscuits, honey and so on.

Foods that can be stored for a long time are generally sealed in sealed packaging, such as rice. There is also alcohol that can be stored for a long time.

Aged vinegar is a thousand years old so far. Vinegar can promote the digestion and metabolism of the human body, and the longer the vinegar is stored, the better it tastes, the higher! Many people have vinegar at home, and after putting it for a long time, there will be lumps of things in it, and they think it is broken, but in fact, it is the condensation of the essence of vinegar.

Rice, sorghum, etc. have the longest storage time, are not easy to deteriorate, and can be stored for 5-10 years or more. Soybeans can be stored for 3-7 years, wheat can be stored for 2-4 years, and corn can be stored for 2-3 years when dried and insect controlled.

The storage time of grain is affected by its own moisture and environmental temperature, as well as its own grain structure, as long as it is not processed and oxygen-deficient grain, it can be stored for a longer time.

Common dry goods are stored for a long time: dried fungus, dried mushrooms, dried vegetables, seaweed, white fungus, yuba, dried bamboo shoots, dried radish, lilies, etc., dry goods can generally be stored in a dry, ventilated and cool place for about 2-3 years, but must be sealed after use, otherwise it is very easy to mold in the humid south. You can pay more attention to the combination of various ingredients, such as fungus can be paired with other vegetables, yuba can be steamed with meat, seaweed can be used when cooking noodles and so on.

Beans are generally commonly used at home, and if they are stored well, there is no problem for a year and a half. You can buy more at one time, such as black beans, mung beans, red beans, soybeans, etc., which can be used to make soy milk for breakfast, can also be used as baby food, and can also be boiled into soup to drink. Generally, it is stored in a cool and dry place, and it can be stored for several years, but it is necessary to do a good job of preventing insects.

In life, we may sometimes forget the expiration date of some foods and lose the opportunity to try them, thinking how good it would be if there were foods that never expire, so I will introduce you to five foods that will never spoil.

Five foods that never go bad

1.Honey

Fresh and ripe honey is 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, and bacteria and yeasts 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.

2.Liquor

Liquor with an alcohol content of more than 10%, which is commonly known as liquor above 10 degrees, has a disinfecting effect on itself. 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.

3.Vinegar

Vinegar has the effect of antibacterial and sterilization, and can be used for food preservation and preservation, 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.Solid table 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.

5.Table salt

The main component 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.

The shelf life of different foods is different. To ensure the freshness and nutritional value of the food, do not store the food for a long time. Let people experience the best taste of food and absorb the best nutrients.
