'Net' recently, playback, video circulated on the Internet, according to the stainless steel kitchen utensils and appliances if long-term acid salt, vinegar, fruit juice, etc, can make the stainless steel from corrosion, thus releasing the heavy metal chromium inside. Sustainable use of releasing chromium stainless steel kitchen utensils and appliances, can create chromium poisoning, liver function of harm human body. Chromium stainless steel kitchen utensils and appliances really can corrode and cause poisoning? Chromium poisoning harm have how old? The reporter interviewed the Beijing chemical industry university, associate dean of the faculty of science square jade. Square jade said, as long as the corrosion does not occur in the process of using stainless steel kitchen utensils and appliances, stainless steel kitchen utensils and appliances of chrome will not migrate into the food, also won't cause chromium poisoning. High quality stainless steel kitchen utensils and appliances of corrosion resistance is very good, generally does not cause chromium poisoning. But is important to note that the acid was corrosive to stainless steel, can make the chromium stripping in the stainless steel, should be to prevent when using stainless steel kitchen utensils and appliances. 'Together will be generated hydrochloride salt and vinegar, the high content of vinegar and salt and long time heating cooked in stainless steel kitchen utensils and appliances, corrosion of stainless steel kitchen utensils and appliances, thus stripping chrome. 'Square jade further explanation. Square jade explanation is to support the conclusion. Jieyang city in fujian province quality measurement supervision and inspection, which had done in 2010 by an experiment, study the influence factors of chromium migration quantity in stainless steel kitchen utensils and appliances. This was listed in fujian province science and technology plan projects of the experiment came to the conclusion that the stainless steel in acetic acid liquid from corrosion, make chrome dissolution and the migration into contact with the food. And the corrosion of stainless steel and chromium stripping degree, with a direct relationship between the acetic acid concentration and temperature of the liquid. Acetic acid liquid concentration or temperature, chromium migration quantity will be increased accordingly. In addition, the stainless steel surface roughness increases, can reduce the corrosion resistance of stainless steel, chromium migration quantity will be increased. According to our country the national food safety standard stainless steel products ( GB9684 - 2011). Regulation, stainless steel products in chromium migration amount must not exceed 0. 4 mg/square decimeter. Former ministry of health in setting the limit standard, generally stainless steel products in cheng fang, cooked food or contact with the food in the process, does not constitute a food safety risk; Chromium stainless steel products in use migration over your limit and may harm human health. Our qc department has repeatedly said that chromium can irritate the skin, mucous membrane, the digestive tract and corrosion resistance, and easy to enter human cells. Inhalation of high content of chromium, can cause damage to internal organs such as liver, kidney, accumulate in the body is carcinogenic, may also induce gene mutation. Since chromium may endanger health, why not require stainless steel kitchen utensils and appliances to chrome? The answer is to do. Square jade explanation, stainless steel is not rusty, has the very good corrosion resistance, because the stainless steel surface can be naturally formed a stable, compact, solid layer of passivation film, the chrome is a necessary component of stainless steel surface passivation membrane. High quality stainless steel kitchen utensils and appliances of passivation film is very strong stability, good corrosion resistance, normal use will not fall off will not dissolve, chrome so there won't be dissolved and migrated to food poisoning. 'However, poor corrosion resistance of the inferior stainless steel kitchen utensils and appliances, easy corrosion rust pollution food, there is a risk of chromium poisoning. 'Said square jade, qualified stainless steel products must not only contain chromium, chromium and must contain enough. The chromium content of stainless steel products usually must achieve 13% above, to avoid rust corrosion. Inferior stainless steel kitchen utensils and appliances are easy to rust, it is because of the chromium content is not up to standard and affects the corrosion resistance. Should have protective effect of chromium, instead will migrate into the food into healthy distresses. So, to avoid chromium poisoning caused by stainless steel kitchen utensils and appliances, first of all must ensure that the quality of stainless steel kitchen utensils and appliances. Second, 'such as easy to rust stainless steel kitchen utensils and appliances, use less as well. 'Square jade said. According to the quality inspection department, stainless steel kitchen utensils and appliances should avoid long time contact with acid, alkali substance; Do not use stainless steel kitchen utensils in traditional Chinese medicine, in case of stainless steel under the condition of heating and the alkaloids in the traditional Chinese medicine (TCM) and organic acid reaction, make the chrome dissolution; Stainless steel kitchen utensils deformation or surface wear, leathery, should be replaced in a timely manner.
