Hi,

There may be different standards in different parts of the world so it will depend on where you export to. Currently EU maximum limits for environmental contaminants are reviewed on a regular basis, and are subject to future revision to take account of the latest evidence and data, but there are currently no maximum regulatory limits in Europe for arsenic or mercury in cocoa products. Please see this document for more information on quality standard for cocoa: http://www.cocoaqual...pr 2016_En.pdf 

 

Best,

Ren

Hi Purnama,

 

I don't have knowledge or experience of cocoa and/or magnets myself but the below threads may offer some guidance into the area.

As a raw material or a finished good?


Because we always have is never an appropriate response!

Hi purnama,

 

As per previous posts, yr query lacks context..

 

What do you mean by "metal" ?????

 

A trivial answer to yr OP is that "magnets" will only detect sufficiently magnetic metals, eg from google - 
 

Magnetic metals include iron, nickel, cobalt and most of their alloys.

Some forms of steel are magnetic, while others are not. Non magnetic metals include aluminium, copper, lead, tin, titanium and zinc, and alloys such as brass and bronze.

Precious metals such as gold and silver are not magnetic

 

 

Is there a specific reason/specification for yr query ?


Kind Regards,

 

Charles.C
