Why do many people hate to buy canned type coke?

Why do many people hate to buy "canned" type coke? It can be done for the following reasons:

The first is the difference in "air volume". When drinking a canned Coke, you rarely get to drink it all in one sitting, so you'll feel like the "amount of air" in the can is enough. If you switch to a plastic bottle of Coke, screw the lid back every time you drink it, open it again the next time you drink it, screw it on again, and repeat the cycle.

In this way, it will feel a lot less gas, so it is not that the taste of the cola has changed, but that different packaging will lead to different drinking habits. Eventually, there will be subjective differences in taste due to differences in the "volume of gas" and carbon dioxide.

Finally, because cans don't leak easily, carbonated drinks are mainly a taste problem caused by the amount of carbon dioxide in them. Plastic bottles are different from metal cans because plastic is a polymer material. The arrangement between molecules should not be as tight as the arrangement between metal atoms, which will make it easier for carbon dioxide to leak.

In fact, the pressure is the same for cans and plastic bottles, and there is little difference in taste caused by carbon dioxide between the two packaging methods of fresh cola. However, during transportation and storage, the pressure of plastic bottles decreases due to deformation of the packaging, while cans do not have this problem. In addition, cans of cola are not easy to store after opening, and it is easy to leak after touching, while plastic packaging cola does not have this problem.

Coca-Cola has been addicted to collaborations over the years and has been selling well with major fashion brands. The brand name of the fashion trend seems to appeal to young people as much as the brand name of Coca-Cola. From clothes to shoes, from headphones to phone cases,Humanity will not be able to stop Coca-Cola from infiltrating every aspect of our lives.

Because there are fewer canned cokes, and it is more troublesome to open, it is easy to scratch your hands.

This should be because canned Coke is more troublesome, which is why so many people hate it.

Because cans are not very convenient to drink. That's why I don't like it.

This one is fine, maybe because it has to be drunk after it is opened, and it can't be placed.

The reason why Coca-Cola modern cans are more expensive than previous cans: I think it must be that the cost of these two cans is the same. Here's why:

First, new packaging categories should be added to new production linesManufacturing costsElevated.

The second verse is late and skillful, and the tank is heightenedSurface areaAs it increases, the cost of materials increases.

Thirdly, the increase in tank height makes the gap between tanks larger, and the wild bond increases the cost of storage and transportation. Regarding the first point, the new packaging size will increase the manufacturing cost in the early stage, but the marginal cost will decreaseThe Coca-Cola Companyshould soon be able to add new lines of businessProduction costsMinimize it.

Personally, I don't think this argument is very convincing. With regard to the second and third points, both can be mathematically formulated.

Estimate. Let's talk about the third point first: the beverage content is the same, let's assume that the volume of the two cans is also the same, and because v can = r h, r h is the fixed value; The cross-section of the voids between the cans can be seen as the difference between the inscribed regular quadrilaterals of the circular cans.

The area of a regular quadrilateral is (2r), the area of a circle.

is r, so the average volume of voids around a single tank is v empty = (4- )rh, and because rh is a fixed value, so v empty is also a fixed value, and the third assumption is not valid.

Cola contains carbonated water, PET bottles are transparent, which will lead to carbonic acid decomposition, and carbon dioxide will slowly escape from PET bottles when the pressure is high, which will affect the taste for a long time. Cans don't have this problem, so the small bottle tastes good.

And I think so, probably because the seal is better.

Do you know why some manufacturers use cartons for beverages at any cost, cartons are far inferior to transparent plastic.

The seal is strong, and the cost of packaging is low, and the transportation loss is also large, but it can protect the beverage from the sun, and the beer and mineral water that have been in the sun for a long time are not good to drink, and will change the taste, which is why the canned is better because it is not affected by the sun.

Because the amount of cans is small, you will feel delicious if you are scarce, and the opaque cans are more mysterious, the red appearance is very drinkable, and the shape of the cans is also very cool.

I also feel the same way, the original solidity of the bottle is invaded by the outside, like the wind blowing the sun.

Personally, I feel that it is a matter of quantity, and the capacity of the bottle is generally relatively large, and the carbonated gas in it is not enough after drinking. The capacity of the can is relatively small, generally 330ml, and it is easy to drink it up, so it feels better.

If you drink the 300ml kind in small bottles, the taste should be the same.

Because it's the essence of concentration

Indeed, one is made of plastic and the other is iron, and the taste is different.

1. Refrigerated storage: If you want to prevent air leakage from a large bottle of Coke, it is best to keep it in the refrigerator at about 2 degrees Celsius, because the solubility of carbon dioxide in water is the largest at this temperature, and the temperature is the best drinking temperature for Coca-Cola. 2. Squeeze the bottle to compress the space in the void as much as possible. In this way, the amount of bubbles coming out of the cola is curbed.

So after pouring it out, it won't be a dead sugar water. 3. In addition, reduce the number of bottle openings and reduce shaking, which can also make Coke run less. But if you want to drink the most refreshing Coke, it is most reliable to drink it all quickly.

250ml。

A 250ml can of Coke has about 150 calories, and Coke contains caffeine, which can relieve fatigue, replenish physical strength, and lift the spirit. It's not a big problem to drink a little bit in moderation, but don't drink too much, and cola is a carbonated drink.

It can easily lead to bone loss, which can cause osteoporosis.

Calcium deficiency leads to bone and joint pain, and soreness in the waist and knees. Long-term drinking of cola can also have a certain effect on the mouth and teeth, which can lead to tooth decay and laryngitis.

Wait. <>

People who should not drink coke.

Patients with high blood pressure should not drink: Drinking too many caffeinated beverages will increase blood lipids, which means that old noise is easy to aggravate arteriosclerosis.

Patients with hyperlipidemia drink more alcohol will increase the deterioration of the condition containing land speed.

Smokers should not be: caffeine in nicotine.

Under the action of mutagenic substances, it is easy to mutate certain tissues of the body, and even lead to the production of cancer cells. To avoid the above harms, you should change the habit of smoking and drinking cola at the same time.

Not suitable for children: due to caffeine on the central nervous system.

It has a strong stimulant effect, and some scholars have proved that ADHD in children is related to this, which can cause children's mental irritability, undiscipline, and decreased academic performance.

The above content refers to Encyclopedia-Coke.

People's Daily Online-Drinking cola is also good But 5 types of people are not suitable for drinking.

Coke cans are mainly made of aluminum. Aluminum is a lightweight, corrosion-resistant, easy-to-process and well-worn metal material, so it is widely used in food and beverage packaging.

Aluminium products are characterized by high strength and good ductility, which allows aluminium cans to withstand carbonated beverages under high pressure. In addition, aluminum is a non-toxic, odorless, and odorless material, so aluminum cans can be safely used in food and beverage packaging.

Advantages and application areas of aluminum:

First, the advantages. 1. Lightweight.

The density of aluminum is only, and the density of Pichun lead is only 1 3 compared to steel, so aluminum products are very lightweight and easy to carry and transport.

2. Corrosion resistance.

Aluminum has good corrosion resistance, and its surface can be oxidized to form a dense alumina film to prevent further oxidation.

3. Easy to process.

Aluminum products can be manufactured into various shapes through processing methods such as forging, pressure forming, casting, and welding, thus meeting the needs of different fields.

4. Good electrical and thermal conductivity.

Aluminum is a good conductive and thermally conductive material, so it has a wide range of applications in electrical and thermodynamic applications.

Second, the field of application.

1. Architecture. Aluminum products are widely used in the construction field, such as window frames, door frames, curtain walls, ceilings and partitions. Aluminum combustion products have the advantages of lightness, corrosion resistance, and easy processing, so they have been widely used in the construction field.

2. Transportation.

Aluminum products have a wide range of applications in the transportation sector, such as airplanes, automobiles and trains. Aluminum products are lightweight, high strength and good corrosion resistance, so they are widely used in the field of transportation.

3. Packing. Aluminum products have a wide range of applications in the packaging field, such as food, medicine and beverages. Aluminum products have good corrosion resistance and sealing properties, so they have been widely used in the field of packaging. <>

But drinking Coke is actually a very peculiar thing, because for people with picky mouths, Coke on different packages actually has a different taste, and many people feel that this is the case after trying it, why is it the same Coke, but canned Coke tastes better than bottled Coke? Actually, it's definitely not that our tongue is wrong, and there is a reason!

First of all, there are many differences between canned cola and bottled coke, not only in terms of packaging, but also in terms of capacity. Because the cans are not as long as the bottles are designed, they are basically only 330 ml, while the plastic bottles are different, basically around 500 ml. And we ordinary people actually think that canned Coke is delicious, also because of its small amount, we can basically drink it and there will be no leftHowever, there are many times when the bottle is not finished and the lid is closed, so that in fact, the gas in the sealed bottle will gradually decrease, and the taste of drinking soda will be reduced!

At this time, there will definitely be people who oppose it, because there are also small bottles of Coke now, so we think there will be differences in taste, in fact, there are certain factors in the packaging! Because canned cola is made of metal, and bottled is made of PET bottles, it is actually far inferior to bottles in preventing carbon dioxide from escaping, and our canned cola is different, the sealing will be stronger, so that the taste will be much better.

But in fact, the real difference in taste is definitely not much worse than we imaginedIn most cases, there are actually psychological factors, because in the eyes of our foodies, Coke has no soul if it is not angry, and it is no different from sugar water when it is drunk. Moreover, plastic cola is not light-proof, so it is normal to "leak" in the case of transportation, and there is a lot of gas in a can, so it fully satisfies people's psychology and will appear to be more delicious.

It is true that a can of Coke will taste better than a bottle, because the can will be a little more cold in the refrigerator than the bottle.

Because canned cola is better chilled than bottled.

Because there are fewer canned cokes, then the gas in it will be relatively sufficient.

Because cans are made of aluminum, they are better refrigerated.

Because canned things are actually better than bottled ones, not just coke.

Because the cans will have more cola, the canned ones are more delicious.

Because the gas of the can is relatively sufficient, it is particularly delicious, and the small amount makes people want to drink it more.

Because the coke in the can will be more filling, it will taste better.

Cans retain the original taste of cola better than plastic, so they naturally taste better.

Because cans are more expensive, after all, the more expensive ones must be more delicious, psychological effects.

The cost of packaging is expensive, at least an aluminum can can be sold for 1 cent, and plastic bottles are not worth much. The production process of aluminum cans is also relatively complex, and the chemical properties of aluminum cans are relatively stable and the taste is better

For the same drink, the actual cost is the same, and the reasons why the plastic bottle on the wall of the can is expensive are:

First, plastic bottles are cheaper than cans in terms of material.

Second, the filling machine for cans is more expensive, and the manufacturer's investment in equipment is also high.

Third, the sterilization requirements for secondary sterilization cans should be higher, and the investment in sterilization equipment will also be large.

Of course, there are other reasons, cans look more high-end than plastic bottles, so many manufacturers use cans when they use cans, but also cans used in high-end drinks, and the cost of drinks is also higher, so most of the canned drinks on the market are more expensive than plastic bottle drinks.

Cola contains carbonated water, PET bottles are transparent, which will lead to carbonic acid decomposition, and carbon dioxide will slowly escape from PET bottles when the pressure is high, which will affect the taste for a long time. Cans do not have this problem, so they have a longer shelf life.

Plastic bottles are affordable, and they are canned for serious occasions.
