There are new regulations on the use of raw materials for containers in Japan

vinyl chloride is a common raw material for manufacturing food packaging and containers for food processing. However, under the action of oil in food, vinyl chloride material will release a harmful substance - phthalic acid, which is suspected to interfere with human endocrine. According to the report of Japanese food on August 1, in response to the above problems, the Ministry of health, labor and welfare of Japan made a decision on the use of raw materials for containers on July 28. It is reported that the specific contents of this decision may be made public this autumn

this decision prohibits the use of plastic films containing phthalates as raw materials in the production of containers and container packages for fats and fatty foods, and adds the implementation rules of correcting the food hygiene law and guiding the industry to the decision

the restricted substance is phthalic acid-2-ethyl-hexanitrodiphenylamine (this chemical name is for reference, and its English abbreviation is "DEHP"). It is used as a plastic plasticizer, which may have an impact on animal reproduction, so it is listed in the list of endocrine disrupting chemicals formulated by the Ministry of environment of Japan, and is included in the list of eight high-risk substances

in June last year, it was found that the above-mentioned bad ingredients entered the lunch box due to the use of gloves during food processing, resulting in the pollution of the lunch box. To this end, the Ministry of health and welfare of Japan has issued a notice requiring that appliances with such materials be avoided in food processing. According to the introduction, the supervision and management measures were also strengthened in the latest decision, and the punishment content of the largest electronic universal experimental machine in China with an experimental force of 1000KN and a level 1 machine, such as several 10 tons of ordinary steel, was added

according to the recent experimental research results of relevant parties, the dissolution degree of DEHP in dried radish, fried meat cakes, Japanese rice balls and other foods is in order. The researchers did such an experiment, that is, when making food, they used gloves made of PVC for operation, and then analyzed and tested the dissolution of DEHP. Experiments have proved that in addition to rice balls, the contact of PVC with oil processed food or oil can help the dissolution of harmful components. In addition, an investigation of 177 kinds of food on the market found that in addition to gloves, plastic equipment such as hoses and food tensile testing machines are now widely used, and contact will also produce the same pollution results, especially from the baby weaning food packaged in soft bags, which also found a higher concentration of dissolved substances

at present, Japan stipulates that the tolerance of DEHP (based on daily intake) is 2000 micrograms to 7000 micrograms per 50 kg body weight, while the EU regulation is much stricter than this indicator, which is set at 1850 micrograms. The highest content detected from 30 grams of dried radish this time reached 4300 micrograms. In addition, there are various electromagnetic disturbance signals contained in other foods that have not yet reached the level of excessive intake. However, dried radish slices are not fat or fatty food, so which foods are more vulnerable to DEHP pollution and how to define the scope of these foods need to be studied separately. In addition, adipate esters, which are also used as plasticizers, have also been studied. However, there is not enough evidence to conclude that this substance should also be included in the restricted list
