What are the main aspects of food safety problems in food packaging paper?

1) The raw materials for the production of food packaging paper are not clean, there are heavy metals, pesticide residues and other pollution or mildew raw materials are used, so that the finished product is infected with a large number of molds, and even the use of social waste paper as raw materials, resulting in chemical residues;

2) Fluorescent brighteners are added in the production process, so that the packaging paper and raw paper contain fluorescent chemical pollutants;

3) contain excessively high levels of polycyclic aromatic hydrocarbon compounds;

4) Like plastic packaging materials, there are also ink printing and dyeing problems.

Due to the high residue of harmful substances in food packaging, food is contaminated and poisoning incidents occur frequently, which brings many unfavorable factors to the creation of a harmonious society. In September 2004, the results of the food packaging (film) spot check announced by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China showed that in addition to the general plastic bags, the failure rate of special food packaging bags was as high as L5. Among them, the main problems are that the health indicators do not meet the national standards and the physical and mechanical properties of the products are poor.

These substandard food packaging bags will have adverse effects on human health during use, especially for the development of children and adolescents. In recent years, the sampling pass rate of packaging bags in various places is generally low, and the pass rate is only 5o. The main reason for the disqualification is that the benzene residue exceeds the standard, not long ago, the ** TV station "Quality Report" broadcast Lanzhou "toxic milk powder" incident, due to the toluene xylene solution residue exceeding the standard, the unqualified rate of food packaging bags is as high as 5o.

Printing issues, whether the material meets the national food safety standards, and the parameters of the material itself.

Correct Answer: Plastic packaging material. Plastic is a kind of polymer material made of polymer resin as the basic ingredient, and then adding some various additives to improve the performance as auxiliary materials.

It is widely used in food packaging and is currently the most important packaging material for food sales packaging. Plastic products mainly have the following safety problems: plastic resin, most of the plastic resin materials used in food packaging are non-toxic, but most of their monomer molecules are toxic, and some of the bends are more toxic, and some have been proven to be carcinogens, such as the styrene monomer in polystyrene resin has a destructive effect on liver cells, and the monomer of acrylonitrile plastic is a strong carcinogen, and the material has been banned in some countries.

Plastic additives, plastic additives generally include plasticizers, stabilizers, colorants, inks and lubricants, etc., all of which have different degrees of toxic effects.

Metal packaging materials. Due to its high strength, high barrier property and excellent processing performance, metal packaging materials occupy a very important position in food packaging and have become one of the four pillar materials of food packaging. Metal packaging materials and products may have the following safety issues:

Due to the poor chemical stability of metal packaging materials and products, they are not resistant to acid and alkali, especially sensitive to acidic food, such as canned food packaged with tinplate products after a certain period of time, due to various reasons, the coating is dissolved, and metal ions such as tin and lead will dissolve into the food in the can, causing pollution; Because the barrier property of metal materials is better than that of other materials, the inside of the package is in a state of no oxygen or less oxygen after a certain period of time, so anaerobic or facultative anaerobic microorganisms have the possibility of value-added, especially foods rich in animal protein, and the residual Clostridium botulinum will produce highly toxic botulinum toxin under anaerobic conditions.

Glass packaging materials. Glass is a solid substance made by melting silicates, alkaline components, metal oxides, etc. at high temperatures. There are many types of glass, and the glass used in food packaging is mainly sodium-calcium-silicon glass.

At the same time, glass is an inert material, non-toxic and odorless buried potatoes, chemically stable, and a relatively safe food packaging material. The food safety problem of glass is mainly the migration dissolved from the glass, and the main migrants include inorganic salts and metal ions. Lead compounds are often added to high-grade glassware, which may migrate into wine or beverages and cause harm to the human body.

In addition, these packaging materials are generally recycled, and there may be foreign matter and cleaning and disinfectant residues in the bottle during use.

Food packaging plays an important role in food safety. First of all, the packaging can prevent external contamination from entering the food, such as dust, insects, etc. Secondly, packaging can prevent food from being affected by environmental factors such as light, oxidation, water evaporation, etc., thereby extending the shelf life of food.

However, if the packaging material itself is unsafe or used incorrectly, it can also pose a threat to food safety.

The packaging materials used in Woxiaoya infant food are in line with relevant national standards to ensure the safety and hygiene of the materials. In addition, Woxiaoya also pays attention to user experience in packaging design, using convenient and easy-to-use, easy-to-open and other designs to facilitate parents to prepare food for their babies.

It should be noted that there may be some chemical residues in packaging materials, such as bisphenol A and other substances in plastic products, and it is necessary to pay attention to choosing safe packaging materials to avoid potential food safety hazards that may exist after long-term consumption. In addition, it is also necessary to pay attention to avoid chemical reactions between packaging materials and food during use, for example, acidic food should not be packaged in iron cans.

Safety hazards of food packaging materials.

1) The hidden danger of the packaging material itself.

At present, there are many food containers and packaging materials allowed to be used in China, and the potential safety hazards that different types of materials may bring are also different. Plastic is one of the most widely used food packaging materials. Its harm is mainly due to the residual toxic monomers and pyrolytes in the products.

Paper products are also a traditional food packaging material, the raw materials for the production of food packaging paper itself may not be clean, there are pollution problems such as heavy metals, pesticide residues, etc., and even the use of waste paper as raw materials, resulting in chemical residues and microbial pollution. Rubber products, which are often used as liners for food packaging materials, may have the potential to leak out synthetic rubber monomers or processing aids. In addition, toxic metal ions may be leached from metal packaging materials, silica may be dissolved from glass materials, and metal oxides may also be dissolved from enamels for ceramic packaging.

2) Illegal addition of various processing aids in the production process.

The non-standard production of packaging materials or containers is also one of the main causes of food safety hazards. Now the vast majority of food companies do not allow packaging companies to mark their own marks on their products, which makes consumers unable to identify the "origin" of the packaging. Because consumers cannot supervise, food companies mostly decide to buy various processing aids based on whether the cost is low, resulting in food safety hazards.

For example, plastic belongs to polymer polymer, which is formed by polymerization reaction of monomer under the action of appropriate conditions and initiators, in order to improve the processing performance of plastics and the use performance of finished products, plasticizers, antistatic agents, slippery opening agents, heat stabilizers and other processing aids are added in the process of making finished products. Plastic monomers and processing aids are low-molecular compounds, which will dissolve from plastics and transfer to food under certain medium and temperature conditions, thereby contaminating food and causing harm to human health.

3) Pollution caused by packaging and printing.

Ink is an indispensable basic material for packaging and printing, and it is also one of the main sources of food contamination. There are two main types of traditional packaging printing inks: resin type and solvent type, and there are harmful substances such as heavy metals, organic volatiles and solvent residues for printing.

1. When buying packaged food, you should carefully check the food label, and pay attention to the production date and shelf life.

The name of the factory, the address, the family defense health license.

number, QS mark.

Whether the outer packaging of the lamp is clear and complete; whether the outer packaging is neat and tidy, and whether there is any damage; Vacuum-packed food should pay attention to whether there is air leakage, tent bags and other phenomena; Whether the canned food has a bulging lid, whether the dry goods and condiments are moldy and insectic; Be cautious about buying imported food without Chinese labeling, once the above problems occur, please do not buy, let alone eat.

2. When buying bottled beverages, in addition to carefully checking the food label, we should also carefully check whether the drinks in the bottle are turbid, precipitated and some unidentified particles, and pay special attention to whether the bottle body of the bottled beverage is relatively soft.

3. When buying Zhaoyuan lack bulk food, pay attention to whether there is a label on the conspicuous position of the food container or the isolation cover, whether the label is complete and standardized, and pay special attention to food hygiene and shelf life, otherwise do not buy.

5. Whether there are additives: check the content of additives, whether they are harmful to the body, and whether there are illegal additives.

The information on the food packaging must be read, otherwise it may endanger your health.

1. Date. When buying food, we have to make sure that the date is fresh, that is, recent, and if there is no recent, we also want to ensure that it does not expire.

Because expired food can produce harmful substances that can harm our health if eaten.

2. Food additives.

Many food additives are harmful, such as glue, coloring, etc.

So when we buy food, it's best to buy something additive-free, and even if there are additives, we should buy some additives that are harmless to the body.

The production date on the food and the uh that means that if there are ingredients, you should look at it.
