Are preservatives harmful to humans, and are vegetable preservatives harmful to humans?

Preservatives are harmful to the human body. 1. Fruit preservatives are definitely harmful to the human body, but fruit preservatives depend on the dosage!Some preservatives are allowed by the state.

2. Fruit preservatives are mainly aimed at preventing the growth of microorganisms and bacteria in fruits and maintaining relative humidity.

To avoid water evaporation, the correct use of fruit preservatives can indeed make fruits play a good role in preservation, if the preservatives exceed the standard or illegally added, it is very harmful to the human body. It may cause genetic damage, liver and kidney function.

damage, which can also lead to chronic poisoning, etc.

Preservatives are harmless to the human body as long as they are not used in excess.

Preservatives are actually common names for additives such as antioxidants, preservatives and film agents, and the dosage of these additives is clearly stipulated in the national standards. The national food safety standard "Standard for the Use of Food Additives" (GB2760-2011) lists a total of 22 additives that can be used in "fresh fruits" or "fresh fruits after surface treatment".

The maximum dosage and maximum residue are specified. The additives used for fruit preservation must be controlled within the range of the national standard, and excessive use is "harmful and unprofitable".

It can be seen that the use of preservatives is a common practice at present, as long as the concentration and residue of preservatives are controlled, the appropriate amount of preservatives will not cause damage to the human body. In addition, the cost will increase after using preservatives, and putting too much preservatives does not mean that the preservation effect is good. Some fruits will change color and even produce peculiar smell after using preservatives, which will be counterproductive.

Some fruit and vegetable products are advertised as "not containing any preservatives" is indeed misleading, garlic soaked in preservatives, fruit and vegetable storage and transportation will be appropriately added preservatives, more used are citrus, grapes, longan and other fruits.

1. An appropriate amount of vegetable preservative will not cause harm to the human body, this preservative type is a preservative, and the effect is:

1) It plays the role of antibacterial and sterilization.

2) Control the rate of aging of fruits and vegetables.

3) Maintain relative humidity to avoid internal water evaporation.

2. [Treatment].

1) In general, as long as it is thoroughly cleaned, there is no major problem.

2) Soak the purchased fruits and vegetables in water for 10-20 minutes, which can decompose these residual preservatives, pesticides and so on.

Types and functions of commonly used fruit and vegetable preservatives].

Fruit and vegetable preservatives can be divided into the following eight categories according to their functions and methods of use:

1) Ethylene remover: It can inhibit respiration and prevent post-ripening aging. Including physical adsorbents, oxidation decomposition agents, and catalyst removers.

2) Preservative: It is the use of chemical or natural antibacterial agents to prevent the breeding and reproduction of mold and other polluting bacteria, and to prevent disease and preservative.

3) Coated preservative: It can inhibit respiration, reduce water emission, and prevent microbial invasion. Including wax film coatings, shellac coatings, oil film coatings, and other coatings.

4) Gas generator: can be ripening, coloring, deastringent, antiseptic. Including sulfur dioxide generators, halogen gas generators, ethylene generators, ethanol vapor generators.

5) Gas regulator: It can produce a modified atmosphere effect. Including carbon dioxide generators, oxygen absorbers, and carbon dioxide removers.

6) Physiological activity regulator: It can regulate the physiological activity of fruits and vegetables. Including bud inhibine, benzyl adenine, 2,4-d.

7) Humidity regulator: regulates humidity. Including vapor inhibitors, dehydrating agents. (8) Other preservatives: such as burnt alum, etc.

Preservatives are a kind of preservatives, mainly to inhibit bacteria and prevent food spoilage, and there is not much harm below the safe amount. However, there is generally no preservative in fruits, and many fruits are preserved with fruit wax, which is an edible wax that is not harmful to the human body under normal circumstances.

Preservatives are not harmful to the human body, and now they are often widely used due to transportation or long-term storage. It is similar to plastic wrap, but it lasts longer than plastic wrap. However, it should never be consumed so as not to endanger the body.

Preservatives are mostly very low toxicity and no long-term harm, and are harmless to humans. Benzoic acid is a kind of food preservative allowed to be used in countries around the world, it is easy to be excreted with feces in animals, does not accumulate, has low toxicity and low cost, and currently occupies most of the domestic preservative market.

If the preservative exceeds the standard or is added illegally, it is very harmful to the human body. It may cause genetic damage, liver and kidney function damage, and can also lead to chronic poisoning, etc., and there will be no harm when used normally.

The preservative is used according to the regulations and will not cause health damage to the human body; However, if the preservative is illegally abused, it will cause certain harm to the human body.

Preservatives, also known as preservatives, generally include two types of substances, one is a sterilant, which is mainly to prevent mildew and decay during fruit storage and reduce loss; One is growth regulators, such as inhibiting fruit ripening and avoiding nutrient loss.

Preservatives have certain harm to the human body, and the most important thing is to judge by looking at the composition of preservatives.

There are many synthetic compounds that can be used for food preservation and preservation, which can generally be divided into inorganic compounds and organic compounds. This kind of preservative preservative has developed rapidly and is widely used, and is now developing in the direction of less dosage, wide coverage, low toxicity and less residue.

This is definitely harmful, it is a three-point poison, but normal people are not afraid as long as they don't overdo it, don't worry too much.

Preservatives will definitely be there, as will color protectants to maintain vegetable color, reinforcing agents and chelating agents. The accumulation of these things in the body for a long time will affect the enzyme metabolism in the body, and the body will have some chronic symptoms of maladaptation. It's best to eat what you grow yourself, fresh and fresh, and don't drink alcohol.

I wish you good health (o) Oh.

Yes, preservatives contain chemical ingredients.

It's definitely harmful. What is harmless, is to buy a bottle and drink it, it's okay, this is called harmless. A lot of vegetables need to be soaked in potions. Take a few sips of that potion, and if it's okay, it's safe.

Fruit and vegetable fresh-keeping film agent is the most widely used and largest preservative in the process of commercialization of fruits and vegetables at home and abroad. It can regulate the respiration of fruits and vegetables, retain moisture, prevent the invasion of microorganisms, and achieve the effect of freshness. It is used to eliminate pesticide residues, improve the quality and shelf life of fruits, and carry out commercial treatment such as cleaning, grading, film preservation and packaging after fruit picking.

In recent years, China's fruit output ranks first in the world, and more than 80% of fruit preservation film agents need to be imported from abroad. At present, the use of morpholine, rosin and other raw materials to produce fruit preservation film has become a prohibited product in the country and the European Union, high-grade fruits, especially export fruits need to be imported. Yunnan Chushanyuan Biotechnology Co., Ltd. new natural fruit and vegetable fresh-keeping film agent products are the key technology upgrades for the production of food additives, food safety makes up for the lack of domestic products, meets the EU CE standards, and solves the key technical problems of China's fruit exports to the EU, Yunnan Chushanyuan Biotechnology Co., Ltd.'s product quality has reached the level of similar products in Europe and the United States, and is in the forefront, in 2017, the company successfully exported 15 tons of fruit fresh-keeping film agent, achieving a breakthrough in the export of similar products in China. It occupies an important position and a large market share in China.

The use of preservatives in an appropriate amount of fresh fruits will not cause harm to the body, only need to be fully soaked before eating fresh fruits, and the surface of the fruit is brushed clean, which can reduce the damage of preservatives to the body.

Some fruits can also be fully soaked in light salt water, which can not only sterilize, but also reduce the harm of preservatives to the body.

In order to ensure the freshness of the fruit for a long time, the vendor will use excessive preservatives, although it can maintain the color of the fresh fruit, but it will produce peculiar smell, which is extremely harmful to human health.
