The newly reopened restaurants and hotels are facing the new problem proposed during the SARS period, namely the meal-distribution system. This is a major challenge to traditional Chinese dining methods. The purpose is to reduce the spread of diseases. This is more acceptable than this, and there are disposable paper cups that have been put into use earlier, although they are all based on the common purpose of blocking the channels for transmission of diseases. As everyone knows, this paper cup helps you block infectious diseases, Some harmful chemical ingredients also subtly invade your body.
Recently, an experimental survey conducted by the Osaka City Environmental Science Research Institute in Japan showed that dioxins may be released during the use of paper cups, western-style fast food packaging cartons, etc., and may cause endocrine disorders and disorders in humans. Carcinogens have also been detected in such disposable products processed from recycled paper. As plastic products flooding people's daily lives release dioxin components, people began to alienate the plastic products in tableware and tableware. In recent years, the environmental protection department has also developed safe alternatives such as paper cups for this purpose. However, it does not last long. It seems that the Japanese experiment is also reminding people that there are still problems in the health and safety of these paper products that do not yet have environmental regulations.
The Uzumaki researcher at the institute began this type of experiment in 2001. She selected 16 wood pulp-based pulp products and 12 recycled paper products, cut them into pieces of 1 cm in size, and placed them in ethanol. Detection of dissolved traces of substances. The results showed that diphenols (BPA) associated with dioxins were detected in 13 varieties of paper pulp, facial tissue, coffee paper, and teabag paper, and contained 34 to 36 ng per gram. The maximum paper content and the higher temperatures in use make it easier to accelerate the dissolution of harmful ingredients.
The 8 BPA contents of eight varieties, such as sandwich cartons for take-away cartons and cartons for fried chickens, are also between 190 and 29,000 nanograms per gram. This is especially true for sandwich-ready reconstituted cartons and once-used synthetic resins. Carbonate tableware has the same degree of BPA dissolution problems. Of the nine varieties of recycled paper containing carcinogenic substances, dimethylamine and benzophenone (MK) were also found to be as high as 1700 to 12,000 ng/g, and the highest carton content was found in vegetables. Microscopy also found that there are a lot of ink and residual particles of thermal paper components in the recycled paper fibers, which are considered as sources of harmful substances, and the source of toxic components in the paper products produced by the new pulp is still unclear.
According to the provisions of the Japanese Food Sanitation Law, the level of dissolution of relevant food packaging, container materials, such as plastics, pottery, metals, and other harmful substances should strictly comply with national standards, but no clear requirements are imposed on paper products. Ozaki researchers pointed out that although the harmful components of these paper products have not yet reached a concentration that directly harms the human body, the expansion of production without restriction is equally an environmental hazard. In response, the Food Safety Officer of the Ministry of Health, Labour and Welfare believes that the environmental safety of paper products in the catering industry has not been raised as a problem, and there are no corresponding laws and regulations to restrict it. If the complaint report received is indeed confirmed, it should be established strictly. Environmental standards. From the development of catering utensils such as plastic cups to disposable cups, it cannot but be said that environmental protection is a major advance, but new experimental data is reminding us that paper cups must be standardized and paper cups should be used with caution.
According to the Beijing Youth Daily, paper cups help prevent you from catching infectious diseases. At the same time, some harmful chemical ingredients have subtly invaded your body. Recently, an experimental survey in Japan showed that the use of dioxins in the use of paper cups, packaging cartons for foreign snacks, etc. may lead to endocrine disorders and disorders in humans. Carcinogens have also been detected in these disposable products processed from recycled paper.
