Foreign Body Detection
If you’re a food manufacturer chances are you’re concerned with foreign body detection. Foreign body detection is a key component of any trusted food manufacturer’s quality inspection processes.
The successful detection of foreign bodies is a priority for all food and beverage producers and manufacturers, and involves identifying risks and establishing plant-wide protocols for preventing contamination.
Types of Hazards
There are three main categories of hazard type when it comes to food manufacturing: biological, chemical & physical.
- Biological: these include certain viruses, bacteria and other pathogenic microorganisms.
- Chemical: these include mycotoxins, pesticide residues, industrial and environmental contaminants.
- Physical: these include physical objects such as metal, wood, glass, machine filings, stones, personal effects such as jewellery, buttons, nail fragments, nail varnish, and hair.
Technology for Detection of Foreign Particles
Every food product comes with its own unique technological challenges when it comes to quality inspection and foreign body detection. But no matter what products you manufacture, there are two primary and proven means of foreign body detection in the food industry.
- Metal Detectors: Metal detectors have the ability to find splinters from machinery, fractions of broken cutters and blades, needles, screws or other metal fragments.
- X-Ray Detectors: State of the art food x-ray detectors respond to metal, stone, bone, plastics and even Teflon. While both x-ray and metal detector systems have the ability to screen the product after the filling procedure, x-ray detectors have a much broader application.
