Magnetic bars are ubiquitous in the food industry. Whether it's agricultural products such as tea and soybeans, dry powder products such as flour and baking ingredients, or even fluid products such as sauces and chocolates as well as beverages, magnetic rods play a vital role in controlling foreign objects. However, the adsorption strength of the magnetic bar is an important indicator of its quality. At present, we choose the magnetic bar adsorption strength should not be less than 8000GS. some big international famous food enterprise customers are more strict, the strength required to reach 12000GS or more, for 8000GS we have no source? Or 8000GS can adsorb how much iron filings, there is no relevant basis? Or is it just the experience of everyone, is the result of experience supported by data?

Thank You!

Is this a standard that your company is setting? If so, then you should provide the justification for that.

 

I am curious where you read that 8000 GS is the standard. I have never heard that before. At least with SGS, I am pretty sure there is no such standard but with BRCGS, they might recommend that.

 

Similarly, for dietary supplement manufacturing in the United States, in 21 CFR Part 111, the magnets need to effectively prevent metal inclusion, so therefore they need to have whatever minimum strength will effectively perform that task.

What precautions must you take to prevent contamination?You must take all the necessary precautions during the manufacture of a dietary supplement to prevent contamination of components or dietary supplements. These precautions include:

(i) Using effective measures to protect against the inclusion of metal or other foreign material in components or dietary supplements, by, for example:

(3) Magnets, or

Perhaps you can find some answers in the attached article.

 

It says 10.000 GS minimum

Thank you for your answer. For why is 8000gs, I also have questions, in China many factories are set up this way, but I do not know the source of this data, I consulted many experts, the answer I was given is based on experience
