It is all because of the interests behind the food packaging that there are hidden health and safety problems

from the carcinogenic PVC cling film to the toxic milk powder, which has made many consumers nervous about food safety, But it is called "special food additive" "In hindsight, the hidden dangers of food packaging safety have been ignored. Recently, Cien interviewed some consumers randomly in some supermarkets and vegetable markets in Beijing. They all said that when buying food, they generally pay more attention to the production date, shelf life or the quality of the food itself, but rarely consider the packaging quality.

printing ink on the packaging contaminated food

reports on chemical contamination of Nestle baby milk in recent days, Once again, people are full of doubts about the health and safety of food packaging. After sampling and testing, relevant Italian authorities found that there was a trace of photosensitive chemical isopropyl thioxanthone in Nestle baby milk. This substance originally existed in the printing ink of the baby milk packaging box, and it may be that a small amount of ink penetrated into the baby milk. Although it is still uncertain whether this product is harmful to human health, the possible harm to infants caused by long-term drinking of this milk cannot be ignored because the infant's organ system is not yet fully mature and has low resistance to external harmful substances. Based on this consideration, the Italian government has ordered the whole territory to seal up "problem" milk

plastic packaging may cause cancer

bisphenol A is a chemical widely used in plastic food packaging. It also exists in tooth fillings or the inner layer of tin cans. Bisphenol A in plastic food packaging can be incorporated into food after heating. It has estrogen like function. Not long ago, US researchers found through animal experiments that bisphenol A may increase the risk of women suffering from breast cancer. The preparation of samples by researchers, also known as tensile test, should avoid the impact performance of the samples affected by work hardening or overheating. Pregnant mice were fed with a small amount of bisphenol A, which is equivalent to the dose that humans are exposed to in daily life. They found that the number of mammary gland cells and the density of mammary terminal bud tissue increased significantly in postnatal mice at 30 days after puberty, and these changes were risk factors for human or animal breast cancer

not long ago, domestic reports on whether PVC fresh-keeping film causes cancer also attracted great attention of the general public and government departments. PVC fresh-keeping film is widely used in the outer packaging of food and vegetables. Its potential harm to human body mainly comes from two aspects: one is that the residue of vinyl chloride monomer in PVC fresh-keeping film exceeds the standard; the other is that DEHA plasticizer is used in the processing of PVC fresh-keeping film. When the PVC fresh-keeping film containing DEHA encounters grease or heating, DEHA is easy to be released, which is harmful to health after entering the human body with food, and may induce diseases such as cancer, congenital defects of newborns and male infertility

food packaging safety is not optimistic

with the improvement of living standards, the variety and quantity of food continue to increase. Urbanization and economic globalization put forward higher requirements for the speed and convenience of food storage and transportation. These factors make food packaging used more and more. In addition, some foods have the problem of "over packaging", such as mid autumn moon cakes

according to statistics, the output value of the global food packaging industry is growing at a rate of 10-15% per year. At the same time, some manufacturers tend to ignore health and safety issues in order to maximize their interests in the fierce competition, and people still cannot fully understand the performance of some substances in packaging materials. It can be seen that the health and safety of food packaging is not optimistic. In recent years, sampling inspection has been carried out for food packaging bags, and the overall qualified rate is only about 50%

Qian Jin, Secretary General of China Packaging Technology Association, pointed out to Cien that there are more and more kinds of green food in the market, but many green food do not use green packaging. Environmental friendly packaging materials, printing inks and adhesives shall be used for green packaging. With the rapid growth of China's packaging industry, we must pay attention to sanitation and environmental protection, so that consumers can have confidence in the health status of food packaging while being assured of the food itself. This requires the joint efforts of the whole society

China's hygienic management measures for plastic products and raw materials for food clearly stipulates that recycled plastics shall not be used for processing plastic tableware, containers and food packaging materials; Plastic products for food must be marked with the words "for food" at obvious places. However, in reality, our food packaging plastic bags are rarely marked with the word "food bag" as required, and most of them are from unknown sources

at present, HACCP standards are enforced in the United States, Canada, Vietnam and other countries. The standard was first applied to American Aerospace food to enhance the core competitiveness of enterprises. Now it has been extended to frozen vegetables, fruit juice, tea, etc. The standard finds out the key control points through hazard analysis on all links of food production, and takes preventive measures and monitoring means to minimize the risk factor, and carries out necessary verification at the same time. Generally, food and its packaging must undergo three kinds of analysis before leaving the factory. Chemical risk analysis to check whether there is pesticide residue or the possibility of chemical reaction; Biological risk analysis to check the possible response to changes in the external environment of organisms; Physical risk analysis to check whether there are metal fragments in the whole. Relevant experts believe that compared with developed countries, China's laws and regulations in this regard need to be improved
