Can plastic containers hold food with vinegar?

Vinegar is a fermented sour liquid condiment, which is made by fermentation and brewing with starchy grains (sorghum, yellow rice, glutinous rice, indica rice, etc.) as the main ingredient, and grain bran and rice husks as auxiliary materials. Vinegar is one of the main condiments in cooking, mainly sour, aromatic, widely used, and is the main raw material of sweet and sour flavor. It can remove the smell and relieve greasy, increase the umami and aroma, reduce the loss of vitamin C in the process of food heating, and dissolve the calcium in the cooking raw materials to facilitate human absorption.

The more famous varieties are balsamic vinegar from Zhenjiang, Jiangsu Province and old vinegar from Shanxi, etc., which are often used in cabbage, mixed vegetables and dishes with a strong fishy smell.

Due to the different raw materials and production methods, vinegar can be divided into fermented vinegar and synthetic vinegar, and its varieties mainly include rice vinegar, smoked vinegar, white vinegar, etc. The main raw materials of rice vinegar are sorghum, yellow rice, bran, rice bran and salt, which are made after fermentation of vinegar koji, which is light brown, rich in fragrance and good in quality, suitable for dipping and stir-frying; In addition to the raw materials of smoked vinegar, which are basically the same as the raw materials of rice vinegar, after fermentation, they are smoked with pepper and cinnamon, etc., and the color is darker, and it is better to store it for a long time, which is suitable for dipping and stir-frying; White vinegar (also known as vinegar essence) is diluted with glacial acetic acid and water, and the content of acetic acid is higher than that of rice vinegar, etc., with a large sour taste and no fragrance. Concentrated acetic acid has a certain corrosive effect, and the amount should be diluted and controlled as needed when used.

Because vinegar is mainly composed of acetic acid, it will corrode metals, but plastic containers are generally resistant to acid and alkali solutions, so they can be filled with vinegar.

There are only a handful of things in the world that can melt plastic: aqua regia, flames, certain strong alkalis...Vinegar is a weak acid and does not react. Tao Da is a plastic bottle.

With metal will leak and there will be acid and it will corrode.

Yes, as long as it's not metallic.

Some people often use the bottle as a spice bottle for vinegar after drinking. This practice may seem like waste reuse, but it is actually harmful to health.

Professor Lin Lirong of the Department of Chemistry of Xiamen University pointed out that plastic products will slowly release toxic substances when they encounter acids, which are harmful to the human body and are not easy to be detected by people, so they must not be used for a long time. Most beverage bottles are made of plastic, mainly made of materials such as polyethylene or polypropylene and adding a variety of organic solvents. Polyethylene and polypropylene are non-toxic and tasteless, and are safe for the human body when used to fill beverages.

However, once polyethylene is corroded by high temperature or acid, it will slowly dissolve and release organic solvents, which will cause harm to the human body.

It has been reported that long-term consumption of food contaminated with polyethylene molecules can cause dizziness, headache, nausea, loss of appetite, memory loss, and even anemia. Therefore, using plastic bottles for vinegar is harmful to human health but not beneficial.

Professor Lam suggested that glassware could be used in the home instead of plastic products for spices, etc. When using plastic products, special attention should be paid to avoid contact with vinegar, detergents, etc., and avoid direct sunlight, high temperature, etc., so as to avoid chemical reactions. In addition, when you buy plastic tableware, you should choose plastic products with PE (polyethylene) or PP (polypropylene) labeling, less decorative patterns, colorless and odorless, and a smooth surface.

Nowadays, all kinds of plastic bottled beverages are favored by the majority of consumers. At the same time, people also have a "soft spot" for empty bottles that hold beverages, and use them to hold condiments such as wine, vinegar, and soy sauce. If it is installed in a short period of time (usually no more than 1 week), it is not impossible, if it is used repeatedly, it is best not to exceed half a year, otherwise, it will endanger human health.

The main raw material for making beverage bottles is polypropylene plastic, which is non-toxic and harmless, and has no adverse effects on the human body when used to hold soda and cola-type beverages; However, since plastic bottles still contain a small amount of ethylene monomer, if fat-soluble organic matter such as wine and vinegar are stored for a long time, chemical reactions will occur. Long-term consumption of food contaminated with ethylene can cause dizziness, headache, nausea, loss of appetite, memory loss, etc., and in severe cases, it can also lead to anemia.

In addition, when wine and vinegar are used in beverage bottles, the bottles will be aged by oxygen and ultraviolet rays, releasing more ethylene monomer, which will deteriorate and change the taste of wine and vinegar stored in the bottle for a long time.

Peanuts contain 40-50 fat, which is twice that of soybeans and higher than rapeseed. It contains about 30 protein, which is more than twice that of wheat and three times that of rice. Moreover, peanuts are easily absorbed by the human body, and the digestibility coefficient is about 90.

In addition, peanuts also contain riboflavin, calcium, phosphorus, lecithin, choline, unsaturated fatty acids and a variety of vitamins, so peanuts are also known as "longevity fruit" with peanuts are the best.

Specific method: Soak half a bowl of raw peanuts with red coat in rice vinegar for about a week, and eat 10 grains in the morning and evening every day. During the course of consumption, watch for a drop in blood pressure. Once the blood pressure is stable, it can be taken every 2 to 3 days.

It is best to soak in a glass bottle.

Plastic bottles are not allowed to contain vinegar. Because the main component of plastic bottles is polyethylene or polypropylene and other materials, but once polyethylene is subjected to high temperature or acid corrosion, it will slowly dissolve and release organic solvents, which will harm the human body and be difficult to be detected if used for a long time.

Vinegar selection skills: 1. Look at the label. According to the requirements of the national standard, the content of total acid should be indicated on the label of vinegar products.

The total acid content is a characteristic indicator of vinegar products, and the higher the content, the stronger the acidity of the vinegar. Generally speaking, the total acid content of vinegar should be. Look at the production date and don't buy expired products.

Look at the manufacturer clearly and don't be misled by similar label patterns. Not all products in the same place have characteristics that represent the products of that place.

2. Look at the color and posture. Brewed vinegar has an amber or reddish-brown color, and the shiny one is preferred. The liquid state is clear, the concentration is appropriate, and the product quality without suspended solids and precipitation is better.

3. Smell the aroma and taste the taste. Good vinegar should have the unique aroma and ester aroma of vinegar, and should not have a bad smell. The sour taste is soft, the aftertaste is long, mellow, not astringent, and there is no peculiar smell.

No. Because plastic products will slowly release toxic substances when they encounter acids, etc., if used for a long time, they will harm the human body and are not easy to be detected by people. The main component of plastic bottles is made of materials such as polyethylene or polypropylene and adding a variety of organic solvents.

Properties of plastics:

1. Plastics are malleable.

As the name suggests, plastic is the material that can be molded. The so-called plasticity of plastic means that the solid plastic can be softened by heating, and then the softened plastic can be put in a mold, and then it can be cooled and then solidified into a certain shape of solid. This property of plastic also has certain defects, that is, it is easy to soften and deform when heated, and some plastics will even be deformed when scalded with water with higher temperature, so plastic products are generally not suitable for contact with boiling water.

2. Plastics are elastic.

Some plastics, like synthetic fibers, also have some elasticity. When it is stretched by external force, the curled molecules are straightened by flexibility, but once the tension is removed, it will return to its original curled state, which makes plastics elastic, such as polyethylene and polyvinyl chloride film products. But some plastics are not elastic.

3. Plastic has high strength.

Although plastic is not as hard as metal, it still has relatively high strength and wear resistance compared to glass, ceramics, wood, etc. Plastic can be made into sturdy gears and bearings on machines.

4. Plastic has corrosion resistance.

Plastics do not rust in humid air like metal, nor can they rot or be attacked by microorganisms in humid environments like wood, and they are resistant to acid and alkali corrosion. Therefore, plastics are often used in water and liquid pipelines in chemical plants, doors and windows in buildings, etc. <>

Vinegar can be placed in plastic bottles, and there is no need to worry that vinegar will corrode plastic bottles, provided that the plastic bottle production is qualified. Even if there are no acidic substances such as vinegar, the plastic bottle will decompose itself under normal conditions, which is similar to vinegar corroding plastic bottles, and cola will also corrode plastic bottles, but the speed of vinegar bean curd plastic bottles is much slower than the corrosion rate of cola.

It's completely okay, it is said that vinegar will corrode plastic products, in fact, it is fine, the so-called slow release, this slow is simply a negligible speed, even if plastic products do not use vinegar, they will release toxic substances in a normal environment, but this speed and amount and the acidity absorbed by drinking a bottle of Coke, it is simply a small thing.

However, the plastic bottles used must be qualified products. Plastic bottles made of PP5 (polypropylene) can be used.

1.Introduction: Vinegar is a traditional condiment in major Chinese cuisines. According to the existing written records, the ancient Chinese working people used wine as a starter to ferment and brew vinegar, and oriental vinegar originated in China, and the history of vinegar brewing according to literature is at least more than 3,000 years. "Vinegar" in ancient China was called "vinegar", "fermentation", "bitter wine" and so on.

酉" is the earliest oracle bone inscription of the word "wine". At the same time, calling "vinegar" "bitter wine" also shows that "vinegar" originated from "wine".

2.Classification: There is no unified classification method for vinegar due to different brewing raw materials and processes. If it is divided according to the vinegar-making process, it can be divided into brewed vinegar and synthetic vinegar. Brewed vinegar can be divided into grain vinegar, sweet and sour (made of starch syrup and molasses raw materials), wine vinegar (made of liquor and edible alcohol raw materials), and fruit vinegar (made of fruit raw materials) according to different raw materials.

According to the different processing methods, grain vinegar can be further divided into smoked vinegar, special vinegar, balsamic vinegar, bran vinegar, etc. Synthetic vinegar can be divided into color vinegar and white vinegar.

No, vinegar reacts with substances in plastic to produce chemicals that are harmful to the human body. Vinegar is best not to be placed in plastic products!

If it is a plastic bottle made of PP5 (polypropylene), it can be used. It is better to choose glass bottles.

No, you can't lose your appetite because of a long time.

No, vinegar is acidic, and over time, the plastic bottle will gradually corrode.

I talked about it in high school chemistry class.

It's not that it's toxic, it's that the airtightness is not good, and it's easy to run off the smell.

If the plastic bottle is non-toxic, it will be fine, and vinegar is a weak acid, which will not react with the plastic and is safe.

It's generally fine, and the bagged vinegar I used to buy was bottled with mineral water. It's okay for a semester. But it's still not good for the body after a long time. It is recommended that vinegar is best served in glass bottles.

Plastic bottles themselves will also age, and harmful substances will be released when they are aged!
