Steel cookware risk assessment On stainless steel cookware manganese content exceeded the problem recently has been of concern to the general public. For this problem, the national food safety risk assessment center, organize food safety experts in the field of occupational health, clinical material science, risk assessment carried out on including Supor related products, including more than 40 batches of stainless steel cookware, sample, including pots, pans , an electric kettle, and issues related to the risk of exchange cookware manganese migration to be held on the health effects, risk assessment of the results of the preliminary announcement, stainless steel cookware average manganese migration to 0.35 mg per kg of food, and low risk of health damage.

National food safety risk assessment center, said manganese is one of the essential elements that play an important role in bone health, antioxidant metabolism regulation, protein and energy metabolism, and other physiological functions, inadequate intake of manganese may cause bone osteoporosis, atherosclerosis, epilepsy and other symptoms, but most of the food and drinking water containing manganese, 0.4-40 mg per kg of manganese content such as cereals, vegetables and fruits in the manganese content of 0.2-10.4 mg / kg. Adult daily intake of 10 mg there will not be a health hazard.
Calculated in accordance with the measured 0.35 milligrams per kilogram of food stainless steel cookware average manganese migration, a 60-kg adult eat three kilograms of food intake from the stainless steel container is 1.05 mg. China's Fourth National Nutrition Survey results show that the Chinese average daily dietary intake of manganese 6.8 mg, plus manganese content from stainless steel container migration, but also less than 10 mg tolerable intake.
Chen Junshi, academician of the Chinese Academy of Engineering, said that people eat every day, the amount of migration from the stainless steel pot, than the normal three meals a day to eat manganese, only a very small proportion.
The national food safety risk assessment center manganese excess occurred mainly in specific industries and occupations, for example, has long been engaged in the manganese mining, smelting and processing, as well as welding industry workers, and the major route of intake is through the respiratory tract, long-term gastrointestinal nutrition patients may intravenous nutrient solution containing an excess of manganese manganese poisoning. Has not yet been found in clinical ordinary residents of cases of adverse reactions, and no use of stainless steel products lead to excess manganese, manganese poisoning cases caused due to the dietary intake of manganese.
December 21, 2011, after the implementation of the new standards for food safety national standard stainless steel products "(GB 9684-2011), the Ministry of Health supporting quiz clear that manganese content exceeded the center of the storm is in the stainless steel cookware enterprise Supor material, stainless steel products, the main material should be used in compliance with the relevant national standards, in line with GB-T3280 materials and grades. Since December 21, 2011, Supor has strict accordance with the requirements of the above standards organization of production, and have all been through the National Household Metal Products Quality Supervision and Inspection Center (Shenyang) test. Before December 21, 2011, Supor is in strict accordance with the then effective national mandatory standard stainless steel food containers standards "(GB9684-1988) organizational production, there was no manganese content exceeded.
