Why don’t you require stainless steel kitchen utensils and appliances that can’t chrome?
Recently there are a lot of stainless steel products that can cause poisoning news release “chrome”, although experts have given you a detailed and clear explanation, there are still some people who remain skeptical.
According to our country’s “national food safety standard stainless steel products” (GB9684-2011) regulation, chromium stainless steel products in the migration amount must not exceed 0.4 mg/square decimeters. 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, digestive tract, and corrosion resistance, and easy to enter human cells. Inhalation of the high content of chromium, can cause damage to internal organs such as the 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.
Stainless steel is not rusty, has 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 the passivation film are 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.
Qualified stainless steel products must not only contain chromium, and must contain chromium enough. The chromium content of stainless steel products must usually achieve 13% to avoid rust corrosion. Inferior stainless steel kitchen utensils and appliances are easy to rust, it is because the chromium content is not up to standard and affects the corrosion resistance. Should have the 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, if easy to rust stainless steel kitchen utensils and appliances, useless as well.
According to the quality inspection department, stainless steel kitchen utensils and appliances should avoid long time contact with acid, alkali substances; 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.
