How many types of additives are there in toxic milk powder?
Thread Content
Has anyone studied how many types of additives are actually in the toxic milk powder? Are there any simple ways for us to detect it easily in our daily lives? This post was last edited by zxh6267 on 2009-2-17 08:06.]
I don’t think so. Under the current market economy system, there are too many profit-driven individuals and companies; it’s not just a matter of a lack of awareness of social responsibility. The key is to improve the regulatory framework and enforce laws strictly.
Toxic milk powder is not of a single type either; the toxic milk powder produced by different factories varies. Common methods for detecting it involve checking its odor, color, texture, taste, and solubility, but not all cases of toxic milk powder can be identified in this way. Besides, melamine cannot be detected without specialized testing. The same is true for toxic milk powder; trace amounts of substances added cannot be detected.
Sanlu collapsed, and at the beginning of the year, there were many advertisements for other milk powders on television, including quite a few from CCTV. It’s clear that milk powder is an essential item in daily life! Strict supervision is necessary for such essential goods, but awareness among businesses and the public is even more important! This isn’t just a technical issue!
Toxic milk powder contains not only chemical substances; I’ve seen on the Internet that it also has various viruses and bacteria. Ordinary people simply cannot detect these things in their daily lives. By the time you notice them, it might be too late, and some child’s health could be compromised as a result. In my opinion, it’s the manufacturers who are too greedy; they want to make more profits and seize market share, which results in chaos. I prefer genuine products, but people are greedy for cheap things, which gives merchants an opportunity to take advantage of them.
I think we should address the issue by focusing on the additives used to meet milk powder standards; for example, melamine is used to increase the protein content readings. Other standard experts should take action ahead of merchants in order to prevent problems before they arise
Establishing standards and strengthening supervision are secondary matters; today they add melamine, and tomorrow it might be replaced with something else! As science and technology advance, moral and ethical education must keep up as well.
In many cases, it’s the foreigners who announce something first, and only then do domestic parties follow up!
It is said that urea was used first instead of melamine, and later **specific standards were established: to measure the level of free urea in liquid milk. As the saying goes, for every inch of progress made against evil, there is an equal increase in its strength. Later, people sought expert advice, and that’s when melamine came into play. It first appeared in the Hebei region; the locals there were very conservative, and it took a year or two before it spread to the Northeast region. As a result, there were no problems with milk in the Northeast region
There are many additives that can increase the protein content measured in milk powder; as long as they contain nitrogen, they can raise the measured value. This was a flaw and inconsistency in the testing standards previously in use in our country (the protein content was calculated by converting the nitrogen content using a certain coefficient). Now, liquid chromatography can be used for testing, which is much better
This still relies mainly on regulatory oversight bodies, industry standards, as well as the corporate community’s own ethical norms! It’s difficult to detect without testing equipment
I think it would be best to develop inexpensive test strips or probes and other testing tools, so that ordinary people can afford to check whether the milk powder they purchase is problematic.
