Question

why wheat flour is usually passed near a magnet before being packed?​

Answer 1

Answer:

A lot of food is passed through metal detectors/ magnetic fields to ensure that no metal has ended up in there during the manufacturing process.

Answer 2

Wheat flour is usually passed near a magnet to remove any remaining tiny metallic pieces before being packed.

• Wheat is processed in flour mills made up of different types of metals.

• During the flour processing, there is a chance that some tiny bits of metal end up mixing with the wheat flour making it harmful to consume.
• Therefore to protect the consumers from consuming flour mixed with metal bits, it is passed under a magnet so that it removes the metal pieces making it safe to consume.
