Can carbonated drinks or milk corrode our bottles?

In our daily life, it has become a popular cultural phenomenon to drink different flavors of drinks on different occasions, including carbonated drinks, milk, tea, coffee and so on. These drinks include carbonated beverages, milk, tea, coffee and so on. In addition to their unique taste and flavor, different beverages also have different textures and specific needs. At the same time, while enjoying these delicious drinks, how to choose the right material of the bottle to hold the drinks also becomes significant. The main research content of this article is to give you a detailed understanding of what kind of bottles can be used for drinks such as carbonated beverages and milk, as well as what you should pay attention to during the purchase process. Choosing the right bottle will not only enable us to better experience the delicious taste of drinks, but also ensure the quality and hygiene of drinks, making our life healthier and more enjoyable.

I. What materials of bottles are suitable for carbonated drinks?

Carbonated beverages are one of the common drinks in our daily life, and there are countless brands of carbonated drinks on the market, with each brand having a different flavor and texture. For consumers, while enjoying these carbonated beverages, it is especially important to choose the right bottle. So, what kind of bottle is suitable for carbonated drinks?

To answer this question, we should analyze the characteristics of carbonated beverages as beverages, its response to various bottle materials, as well as appearance and taste and other perspectives. First, let’s understand the characteristics of carbonated drinks.
The characteristics of carbonated beverages and their reactions and effects on bottle materials are knowledge that involves physics, chemistry, and other subject areas. Carbonated beverages are made by mixing carbon dioxide gas and water sweetened with sugar, and are characterized by a refreshing taste, sweet and sour texture, and rich bubbles. The materials chosen in the production and storage of carbonated drinks have an indirect effect on the taste, hygiene, and quality of the beverage.
From the physical point of view, the solubility of carbon dioxide molecules in carbonated beverages is affected by temperature and pressure, where the solubility of carbon dioxide molecules will be higher under low temperature and high pressure conditions, presenting more bubbles and a stimulating taste. Since carbonated beverages contain carbon dioxide gas, if they come into contact with unsuitable materials, the carbon dioxide gas will escape, which will lead to the deterioration of the taste of the beverages. Additionally, as carbonated drinks have more gas in them, it can damage the airtightness of the seal and cause the drink to spill out of the bottle. Therefore, it is not recommended to use bottles with sealing function to hold carbonated drinks, beer and other drinks containing more gas. The thermal conductivity, hardness and stability of the bottle material, on the other hand, will affect the maintenance of the temperature of carbonated drinks, the fixation of carbon dioxide gas and the occurrence of other chemical reactions. Overall, different materials will react differently to carbonated beverages.
Common bottle materials, such as glass, stainless steel and plastic, interact with carbonated beverages in different ways. Specifically, the following are the characteristics of different materials when storing carbonated beverages in bottles:
1. Glass: Since glass does not contain chemicals and is not prone to chemical reactions, glass is one of the most suitable bottle type for storing carbonated beverages. In addition, glass bottles can better reflect the color and bubbles of carbonated beverages, making it visually more aesthetically pleasing.
2. Stainless steel: Stainless steel bottles have the characteristics of high temperature resistance, easy to clean, and corrosion resistance, etc. 304 stainless steel is one of the most common stainless steels, which contains 18% to 20% chromium and 8% to 10.5% nickel and other non-ferrous elements. It is an austenitic stainless steel,and its conductivity and thermal conductivity are lower than that of carbon steel. It has a certain degree of magnetism, but less steel. It also has higher corrosion resistance than ordinary steel.
However, when serving foods such as milk, carbonated beverages and tea, the acids in them can damage the oxide film on the surface of the stainless steel and cause elements such as chromium and nickel to gradually dissolve and be released into the food. These elements can be potentially harmful to human health, although there is no need to limit the use of stainless steel, but it should be noted that if used improperly, such as long storage or frequent alternation of hot and cold, will lead to the internal insulation bottle bacteria breeding, odor and other problems, so you need to timely cleaning and maintenance. At the same time, when buying insulation bottles, we should choose a style that can be easily disassembled or cleaned to facilitate cleaning and disinfection. For milk and carbonated beverages and other perishable drinks, it is recommended to prepare them fresh before drinking or clean the cup in time after consumption to ensure the quality and hygiene of the beverage.
Compared with 304, 316 stainless steel has better corrosion resistance and high temperature resistance, making it a high-quality stainless steel material. Therefore, bottles made of 316 stainless steel can better maintain the temperature of the drink and may be safer compared to 304 stainless steel bottles. However, it should be noted that, as mentioned earlier, since some drinks contain certain acids, so even cups made of 316 stainless steel should avoid long-term storage and repeated heating to reduce the release of metal elements.If health and safety are more sought after, you can also consider using titanium bottles. Titanium as an inert metal, below 1000 ℃ will not react with other substances, so you can rest assured that it can be used in tea, milk, beverages and other hot drinks.
3. Plastic: Plastic bottles are lightweight, portable, easy to clean, and relatively more suitable for carrying carbonated beverages outside. However, it should be noted that plastic bottles are not suitable for long time storage of carbonated beverages, because the plastic material will gradually release harmful substances, thus affecting the quality of drinks.
4. Ceramic: Ceramic coated stainless steel bottles with acid and alkali resistance will not release elements such as chromium and nickel, while also maintaining the excellent characteristics of stainless steel bottles, which is a healthier and more practical choice.
In general, when choosing a bottle of carbonated beverages, glass bottles,ceramic bottles and titanium bottles are safer and healthier, the use of stainless steel insulation bottle should pay attention to timely cleaning and maintenance. In short, we need to conduct research and think in a rational, scientific perspective. The material, shape and size of the bottle will have a different degree of impact on the taste and aesthetics of carbonated beverages, we need to be guided by the rationality of science, to make a reasonable choice and drinking.

II. What material bottles are suitable for milk?

In addition to carbonated beverages, milk is also one of the common drinks in our life. As a very important food resource for human beings, milk also plays an important role in people’s daily diet. Milk is rich in protein, minerals and vitamins, making it a highly nutritious beverage. And for how to choose the right bottle to enjoy milk, also need to carry out some understanding analysis.

From the perspective of the bottle material to look at the characteristics of milk and the impact on it, we need to consider the following aspects:

The first is the bottle material and thermal insulation performance: The ideal drinking temperature of milk is 5~10℃, so you need to choose a bottle with better heat preservation performance or cooling treatment.

The second aspect is the acidic reaction of milk: Milk contains pcontains various ingredients such as protein and sugar, which are easy for bacteria to multiply and produce acidic reactions at room temperature. Therefore, special attention needs to be paid when choosing bottles that react to milk. Generally, plastic bottles, aluminum bottles and other metal materials are prone to react with milk, thus affecting the taste and texture of milk.In contrast, materials such as glass and ceramics have less of an effect on the milk and are more conducive to maintaining the fresh taste of the milk.

The last aspect is appearance and comfortable grip: The appearance and grip of the bottle is also an important factor in considering a milk bottle, which involves the psychological feeling of people in the process of enjoying milk. Generally, glass, ceramic and other materials of the bottle can better reflect the texture and color of the milk. On the other hand, parchment bottles and plastic bottles are gradually being eliminated as they affect the texture and experience during milk tasting.

Here are the characteristics of different materials when storing milk in bottles:

1.Glass: Glass bottle is one of the more common types of bottles and are characterized by being transparent, smooth and easy to clean. Bottles made of this material will not affect the taste of milk and are also more resistant to high temperatures, which can better maintain the temperature of the milk.

2. Ceramic: Ceramic bottle is a more traditional type of bottle, which is characterized by warm texture, not easy to deform, and easy to clean. This type of bottle has a better insulation performance, which can maintain the temperature and taste of the milk, so that the taste of the drink is kept in the best state.

3. Stainless steel: Stainless steel bottle have the characteristics of high-temperature resistance, easy to clean, not easy to corrode, etc., but the milk is rich in protein, long time placed in the insulation bottle, the microorganisms in it will be easy to reproduce, resulting in milk deterioration, and even produce flocculent, easy to cause abdominal pain, diarrhea, and other gastrointestinal discomfort symptoms after drinking. In addition, the principle of storage of milk in a stainless steel bottle is similar to that of carbonated beverages,which contains lactose and other acidic substances, long-term storage in a thermos bottle, may be chemical reactions with the inner wall of the thermos bottle, resulting in the precipitation of harmful substances.

In summary, the problem of milk and tea is that it is easy to deteriorate, while the problem of carbonated beverages is the release of gas, which is the most obvious impact in the insulation bottle: constant temperature environment to accelerate the deterioration process, the release of gas in a sealed environment resulting in an increase in the volume, the pressure increases the existence of safety hazards (but also due to the deformation of the structure of the insulation will be destroyed or because of the pressure caused by the reason of the unscrewing).

Choose what kind of bottle to enjoy the milk need to be rational, scientific point of view to choose, according to the characteristics of milk and their own needs to be considered comprehensively. Different bottle materials for milk hygiene, taste and aesthetics are different, we need to choose according to scientific and practical needs in order to achieve the best dietary results.

III. Other beverages

Choosing bottles made of different materials to serve drinks can better protect and present the quality of the drinks, as well as enhance the taste and enjoyment of the drinks.

For hot beverages, such as coffee and tea, it is best to choose ceramic or glass bottles. Ceramic bottles can maintain the temperature of the drink and are less likely to conduct heat, avoiding scalding the mouth. In addition, the texture of ceramic bottles can mask some of the bad flavors that may exist in the drink itself, such as the astringent taste of some famous teas.

Glass bottles look transparent and beautiful, allowing people to appreciate the color and foam of the drink, while also allowing people to feel the temperature of the drink, and another advantage is that it does not produce odors, the material is free of foreign substances, and is harmless to health.

For cold drinks, such as juice, iced tea, etc., it is best to choose glass or plastic bottles. Glass bottles can see the color of the drink, and easy to clean. Plastic bottles are light and easy to carry, suitable for use outdoors or traveling. However, the transparency of plastic bottles is poor,and can age due to ultraviolet radiation, producing odors,and they are also susceptible to aging and odor caused by ultraviolet rays, so they are less likely to be used for high-quality beverages.

For alcoholic beverages, such as red wine and white wine, it is best to choose a decanter or red wine glass. A decanter can help release more aroma and flavor from red wine, while a red wine glass has a special bottle design that allows red wine to more fully emit aroma and flavor in the glass.

In short, according to the characteristics of different drinks to choose different materials of the bottle can better show the quality of the drink, improve the comfort of enjoying drinks, but also to ensure the hygiene and safety of the bottle.
