FOOD SAFETY

Upping the detection systems game
by Ryan Atkinson

C

ommissaries, central kitchens and intermediate wholesale bakeries have
long fought the detection battle. Identifying hazards, implementing processes and
ensuring corrective actions are taken isn't
just good business practice, it's now a FSMA
Preventative Controls rule.
Food safety is at the top of everyone's mind:
the producer, the consumer and the government.
"In commercial baking operations where
bread is being prepared for baking at local
stores, or being baked, Mettler Toledo specialists have found an increase in not only
inspecting products for potential contaminants such as metals, but also an increase in

the degree of those inspections," says Camilo Sanchez, metal detector product manager
for Mettler Toledo. "Food safety has become
a significant concern."

"Since it already supplies inspection
equipment to governmental agencies,
Mettler Toledo also has staﬀ in-house
trained in completing and managing
the complex contracts that government
groups often require."

many facilities are increasing their detection capabilities. Sanchez notes a large na-

How it works
Bob Ries, with Thermo Fisher
Scientiﬁc, details how metal
detectors and x-ray inspection
systems work.
Metal detectors ﬁnd small particles
of nonferrous and stainless steel
using coils wound on a nonmetallic
frame and connected to a highfrequency radio transmitter. When
a particle of metal passes through
the coils of a metal detector, the
high-frequency ﬁeld is disturbed
under one coil, changing the
voltage by a few microvolts. The
output is used to detect metal.
Multiple transmit coils can be
conﬁgured to yield a more eﬀective
magnetic ﬁeld and much improved
sensitivity so that metal spheres
up to 20% smaller in diameter
can be detected reliably. Below is
an illustration of a typical metal
detector coil system.
X-ray inspection systems are based
on the density of the product
and the contaminant. X-rays are
simply light waves that we can't
see. X-rays have a very short
wavelength, which corresponds
to very high energy. As an X-ray
penetrates a food product, it loses
some of its energy. A dense area,
such as a contaminant, will reduce
the energy even further. As the
X-ray exits the product, it reaches
a sensor. The sensor then converts
the energy signal into an image of
the interior of the food product.
