Why don t beer bottles be made of plastic, like Coke? And Coke to use

Plastic bottles can't hold beer, beer is in glass bottles, it's easy to hurt people, and it's also very inconvenient to transport.

Then why can't you take plastic bottles, that is, the oxygen permeability rate of plastic bottles is relatively high, generally after plastic bottled beer, it deteriorates on the same day, and it will be broken immediately, but nano plastic bottles can effectively isolate the transmission rate of oxygen, it can hold beer, now it is said that the United States already has this nano plastic bottled beer, our country has made this material to export to Japan, and is now cooperating to consider it as a plastic bottle for beer in our country.

There's too much pressure inside.

Due to the particularity of beer, the bottle of beer must be pressure-resistant and fresh, so the beer bottle is generally a dark-colored bottle, and the glass bottle has better freshness than the plastic bottle, and the pressure is resistant, so the current use is glass, and there are now plastic bottles abroad, but there are not many of them, because the plastic bottle can not completely replace the glass due to technical problems.

Upstairs, what you said is too absolute, a lot of liquor is packed in plastic barrels, and some are packed in plastic bags, don't say you haven't seen it.

To put it bluntly, the beer is very gasy, and it is sealed in glass bottles.

Alcohol corrosives, and polyethylene produces harmful substances. Have you ever seen plastic liquor?

There are three reasons: 1. Alcohol and other substances in beer will be compatible with organic substances in plastic bottles, making beer contain substances harmful to the human body. 2. If you use plastic bottles to fill beer, because of the limited barrier, it is easy to lead to oxidation of the beer in the bottle and the loss of carbon dioxide.

Glass bottles have better "freshness" performance than plastic bottles, and they are pressure-resistant, so most of the beer is packaged in glass bottles. 3. After the beer is filled, it needs to be "pasteurized" to ensure the quality of the beer and extend the shelf life. Plastic packaging may not tolerate pasteurization.

In addition to glass bottles, beer is also available in cans. As a kind of lightweight packaging, cans are gradually becoming the mainstream of beer packaging because of their excellent sealing and light-proof properties, as well as being safer, more portable and environmentally friendly.

Why are beer bottles dark.

One of the most important ingredients for brewing beer, hops, can give beer a slightly bitter refreshing taste, and the composition of hops is very unstable, it is easy to decompose under sunlight, producing an unpleasant smell, so beer bottles are often dark. If the glass bottle contains ferric ions, then the bottle will turn green, and some beer bottles are brown, because the glass bottle contains ferric ions, which also protect the beer better than the green one.

As for the colorless and transparent beer on the market, it is that the hops are specially treated during the brewing process of the beer.

Logically speaking, cans, glass bottles and plastic bottles.

The coke in the package is the same, and when the company leaves the factory, there is no need to fill different concentrations of cola for different material packaging. But when many people drink it, they find that there are subtle differences in the taste of cola with different packaging materials, and the cola in glass bottles will taste better and have a sweeter taste. So why is this happening?

Personally, I think that the main reason is that the properties of glass bottles are stable and will not corrode and penetrate with cola, so the flavor of cola can be preserved to the greatest extent, and the taste is naturally better than that of plastic bottles.

Carbon dioxide in bottled Coke.

Pressure ChangesWhen filling glass and plastic bottles of Coke in the factory, the gas pressure and carbon dioxide concentration should be about the same, and there should be no difference in taste. However, during specific storage and transportation, the plastic bottle will be deformed due to weight pressure, which may cause the gas pressure in the bottle to drop to a certain extent, resulting in a lower taste; Coke in glass bottles is stronger, so this will not happen.

In fact, the difference in taste between plastic bottles and glass bottles of cola is mainly caused by the difference in packaging materials. Plastic bottles due to their material, which contain acetaldehyde.

It is likely that it will gradually dissolve in the cola under the corrosion of the cola, which will affect the taste of the cola and slightly change its original pure taste.

Glass bottle cola glass bottle cola because of the use of glass as raw material, so the properties are relatively stable, neither elements will be dissolved into the cola, nor will be corroded by the cola to react, basically avoiding the negative impact of plastic packaging materials. Therefore, glass bottles preserve the original flavor and taste of cola to the greatest extent, and it is naturally more refreshing to drink, but if you use glass bottles for cola, the cost of raw materials will be higher, and you should be more careful in storage and transportation, so as not to break the glass bottles and increase a certain cost.

Because glass bottles are generally refrigerated, the lower the temperature, the better the taste, so glass bottles are better than plastic bottles.

Synesthesia effect. The glass bottle looks nice and makes people think that the coke inside is a little more delicious, while the plastic bottle does not see the liquid inside.

Why don't you use plastic bottles for beer?<>1. Pressure resistance. The pressure resistance of glass bottles is better than that of plastic bottles.

2. The organic matter in the plastic will be dissolved in the beer. Because the alcohol in beer is organic, and the plastic in plastic bottles is organic, and these organic substances are soluble in alcohol, it is not recommended to use beer in plastic bottles.

3. Barrier performance. The barrier performance of plastic bottles is not as good as that of glass bottles, which can easily lead to the loss of carbon dioxide in beer and affect the taste.

Beer is not bottled in plastic, mainly because plastic can negatively affect the quality of beer. Not only do plastic bottles not fully preserve the fresh taste of beer, but they can also cause chemical reactions that can affect the alcohol content, taste, and quality of beer. In contrast, glass bottles can better maintain the quality of the beer, as glass is a material that is odorless and does not react chemically with the beer.

In addition, the negative impact on the environment caused by the manufacture and use of plastic bottles is another reason. When plastic bottles are piled up in landfills along with other waste, they can leak toxins and cause environmental pollution. In addition, the manufacture of plastic bottles requires the consumption of large amounts of fossil fuels, and the use of these fossil fuels is also harmful to the environment.

Another reason is that breweries tend to use glass bottles instead of plastic bottles. From a market point of view, breweries prefer to use glass bottles to package their products, because glass bottles have a higher texture and are easier to promote in the market. In addition, glass bottles can also better protect the beer to ensure that the taste and quality of the beer are not compromised.

Overall, there are many reasons why beer is not bottled in plastic, the main one being that plastic can affect the quality of beer and have a negative impact on the environment. In a society that is increasingly focused on sustainability and environmental protection, the use of glass bottles not only helps to maintain the quality of beer, but also helps to protect the environment. <>

If plastic bottles are used to hold beer, because of the limited barrier properties, it is easy to cause oxidation of the beer in the bottle and the loss of carbon dioxide. Glass bottles have better "freshness" performance than plastic bottles, and they are pressure-resistant, so most of the beer is packaged in glass bottles. In most beer production, after the beer is filled, it needs to be "pasteurized" to ensure the quality of the beer and extend the shelf life.

Plastic packaging may not tolerate pasteurization. manufacturing costs, glass costs less than plastic; The cost of glass products can be reused, and plastic does not be.

Beer is an alcoholic beverage made from malt and barley malt as the main raw materials, with hops, liquid gelatinization and saccharification, and then liquid fermentation. Beer is the oldest alcoholic beverage of mankind and is the third most consumed beverage in the world after water and tea. Beer was introduced to China in the early 20th century and is a foreign alcohol.

Beer is a type of beverage brewed with malted barley as the main raw material. It has the lowest alcohol content and high nutritional value, and the ingredients include water, carbohydrates, protein, carbon dioxide, vitamins, calcium, phosphorus and other substances. It is known as "liquid bread", and regular drinking has the functions of relieving heat and fever, helping digestion, appetizing and strengthening the spleen, and increasing appetite.

The maximum amount of beer to be consumed is not more than litres per day. In addition, regular consumption of beer in large quantities can lead to obesity (beer belly). It is not advisable to use hot water bottles to store bulk beer; It is not advisable to drink beer that has been stored for a long time; It is not advisable to eat pickled and smoked foods at the same time; It should not be drunk with strong liquor; It is not advisable to take medicine with beer; It is not advisable to drink beer after sweating; Frozen beer should not be consumed.

But this is also a strange phenomenon, because people who like to eat will find that the taste of Coke is not the same, after eating it once, everyone found out this, it is obviously Coca-Cola, but it is better than bottles? It's not that our tongue is wrong, it's something else!

First of all, canned and bottled Coke are very different not only in terms of packaging, but also in terms of volume. Since cans do not have the length of a bottle, they are generally 330 ml, but plastic bottles are different and are generally 500 ml. Most of us will think that canned drinks are good because there are not many drinks in the can, so we can drink them all, but most of the time, we will close the lid on the mouth of the bottle, so that the air inside is thinner and thinner, and the fragrance of the drink will become weaker and weaker!

At this time, there will definitely be some objections, after all, we have also launched a small bottle of drink, the taste will be different, but in fact, there are some reasons! The cans are made of iron, while the bottles are PET, which is much worse than ordinary bottles in terms of preventing CO2 escape, but our cans are different, our cans are much better than ordinary cans.

However, the taste is not as good as we think, more often than not, it is a spiritual gap, for a person who loves food, there is no gas, there is no spirit, like a cup of ice cream. In addition, the plastic cola itself does not have any shading effect, so it is natural to "leak" during transportation, and a large bottle of air is enough to satisfy people, and the taste is better.

The material of the bottle of Coke is different, the density is evacuated, so the gas flows out. The last point is to avoid light, we all know that bottled drinks are transparent, and they are made of plastic, so the light will pierce into it, which will greatly affect the taste and texture of Coke. Canned drinks don't have such a problem at all, so they naturally taste better.

The main reason is that aluminum cans will have better intimacy than plastic bottles, if it is a bottled coke, the bottle is transparent, it will be affected by light, and a chemical reaction will also occur, and the taste will be reduced.

I think this may be because canned cola and some bottled coke, their dosage is not the same, and the canned cola will also have a better seal than bottled coke.

Although Coke is available in cans and bottles, I personally think that canned ones are better to drink, and they have a soul together, but in fact, many times they are still psychological.
