The supervision of grain and oil quality is very important to the people, and the magnetic properties of powdered food products such as wheat flour (flour), glutinous rice flour (tangyuan powder), and corn flour (including various snack nutritious corn flour) purchased on the Chengdu market Metal determination is particularly important. Using a magnetic metal detector for sampling, it was found that the magnetic metal (iron scrap) was severely exceeded.
The reason that the magnetic metal products of powdered grain products are seriously exceeded is because these food production plants are not equipped with magnetic separation iron removal equipment in accordance with the process requirements for the production of powdered grain products. Although some plants also installed some magnetic separation equipment, due to improper installation, weak magnetic attraction and poor management, they did not achieve the desired iron removal effect. o The existing testing methods are backward and have not been strictly inspected according to national regulations. Many manufacturers do not have testing equipment and do not test this item. Some manufacturers have inspection equipment, but due to low magnetic attraction, inspection operations are wrong, and the The iron filings in the powder are difficult to detect, so the problem of excessive iron filings in the product has not been found for a long time. » There is a misunderstanding of "iron deficiency" among some people. They think that the human body does not need iron supplementation? In flour, glutinous rice flour, fast food corn flour contains a certain amount of iron shavings, eat "good and harmless," and therefore do not want to actively remove iron scraps in food. This is because they do not know that the iron needed by our body is mainly composed of liver, lean meat, egg yolk, beans and fish in plants, and some vegetables (such as spinach and celery) that are rich in organic molecules. Ingestion of iron compounds is not the iron of the machine.
The use of magnetic metal detectors found that, in view of the above situation, all levels of quality and technical supervision and the competent authorities should specify the relevant quality supervision and inspection stations (institutions) for each production plant and in the market season to carry out the development of powder Special inspections of magnetic metal products for grain products, if any do not meet the standards, shall be ordered to suspend production for rectification, and the market shall prohibit sales; each powdered grain product manufacturing plant shall be equipped with advanced and powerful magnetic metal detection instruments and shall be tested as required. Quality control, and rational placement of reliable and powerful magnetic separation iron removal equipment. We strive to effectively remove iron swarf in the production process to ensure the quality of powdered food; the quality supervision, consumer associations and the main needle department of the production enterprises adhere to supervision. At the same time, inspecting, vigorously publicizing the magnetic metal is a foreign matter impurity. Excessive harm to the body. Increase the scientific knowledge of people and consciously safeguard the people's health.
