Is zero-degree cola preservative really exceeded?

For the protagonist of this incident, the preservative contained in Coca-Cola Zero, is it really exceeded? What are the other beverages in China? What does the addition of preservative to beverages bring to the human body?

Preservatives exceeded the standard

Zero-degree cola preservatives exceeded the standards, let us know that the Mainland and Taiwan have different standards for carbonated beverage preservatives. In the Mainland, "methylparaben" can be added, but Taiwan is prohibited from adding it. In the Mainland, the state stipulates that the maximum allowable amount of methyl paraben for each kilogram of beverage is 1 gram, and Taiwan's original lotion contains 2.062 grams of methyl paraben per kilogram. Coca-Cola claimed that the sample tested in Taiwan was an undiluted concentrated stock solution, and the final product was diluted to a concentration of less than 0.1 g/kg.

While benzoic acid is the most widely used preservative, hexadienoic acid is also approved by the state. China's food additives standard stipulates that the maximum amount of benzoic acid used in carbonated drinks is 0.2g/kg. Taiwan’s regulations in China stipulate that the highest amount of benzoic acid in beverages without carbon dioxide is 0.6 g/kg. Taiwan stipulates that the highest dosage of hexadienoic acid is 0.5 g/kg in carbonated drinks and carbonated drinks.

The hazard of preservatives exceeding the standard

The methyl paraben in Coca-Cola at zero degree is characterized by high safety and lethal dose of 4 grams per kilogram. That is, a person weighing 50 kilograms will achieve a lethal dose after taking 200 grams per day. Although the harm is not great, this preservative will still increase the burden on the human liver system. If you consume large amounts of methyl paraben, you may cause gastrointestinal discomfort, inflammation of the skin, mucous membranes and the production of estrogen. This preservative is often added to foods and cosmetics. Among these, benzoic acid and hexadienoic acid may also cause side effects on the skin and eyes.

What are the preservatives in other drinks?

The vast majority of beverages and packaged foods are intended for long-term preservation, and food preservatives are often added. Preservatives are food additives used for the purpose of maintaining the original quality and nutritional value of foods. They can inhibit microbial activity, prevent spoilage and extend the shelf life. The prescribed preservatives include 25 kinds of benzoic acid, sodium benzoate, sorbic acid, potassium sorbate, and calcium propionate. China has so far only approved 32 kinds of food preservatives that are allowed to be used, among which benzoic acid and sorbic acid are most commonly used. Benzoic acid is more toxic than sorbic acid, and its bacteriostatic effectiveness is only 1/3 of that of sorbic acid with the same preservatives of acidity value. Therefore, sorbic acid has been gradually used in many countries. However, due to the low price of benzoic acid and its sodium salt, it is still used as the main preservative in China and is mainly used for carbonated beverages and fruit juices.

Preservatives under the standard

Most of the preservatives used are artificially synthesized, and use of the standard will cause some damage to the human body. Therefore, China has strict regulations on the use of preservatives. It is clear that preservatives should meet the following standards:

1. Reasonable use is not harmful to human health;

2. Does not affect the digestive tract flora;

3. In the digestive tract can be degraded into the normal ingredients of food;

4. Does not affect the use of antibiotics;

5. Does not produce harmful ingredients when heat-treated.

How to deal with the use of preservatives in life

We must correctly understand and rationally treat the preservatives in foods and master general knowledge about food preservatives in order to be able to clearly and clearly purchase foods.

Children, pregnant women and other special people belonging to special periods of physical development should focus on protection of food intake. It is recommended not to give them foods that use excessive amounts of preservatives to protect their health; purchase foods and beverages. Whenever possible, purchase products that are reputable and can stand the test of the market, because the preservatives used in such products are more prudent and secure, and the labels are often more realistic.

For some small and medium-sized enterprises in the product description or advertising claims "this product does not contain any preservatives" do not believe easily. In recent years, some preservatives that must be used in foods are also developing toward safety, nutrition, and pollution-free. New preservatives such as glucose oxidase, protamine, lysozyme, lactic acid bacteria, chitosan, and pectin decomposition products have been Appears and is approved for use by the State. It is recommended that you should be the first to choose foods containing natural preservatives where possible to ensure that your health is not compromised.

Many people think that preservatives are certainly harmful to the human body. Everything that contains preservatives does not touch, but now many food and beverages have been added with preservatives. It is impossible to escape from preservatives. Only by understanding it and understanding its role can we achieve a modern and healthy life.
