tional restaurant chain that prepares loaves
of bread in 50 of its own central bakeries for
finished baking in its locations.
"In recent years the company installed approximately 60 Mettler Toledo metal detectors in those bakeries to inspect for metal
contaminants," Sanchez says. "Originally
these were basic model detectors, but more
recently the company has begun replacing
those detectors with Mettler Toledo's Profile
Advantage metal detectors, the most sensitive equipment."
The Profile Advantage, according to the
company, incorporates a "revolutionary
breakthrough" in metal detection sensitivity.
A multi-simultaneous frequency technology
helps deliver sensitivity that maximizes detection and can ensure end-user brand protection.

"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."

"This equipment features multiple frequency
detection, which enables the systems to detect metal even in warm and moist bread,
where the bread's increased conductivity can defeat typical metal detectors," says
Sanchez.

Multi-simultaneous frequency technology
analyzes product signal data captured across
a wide spectrum of frequencies simultaneously. This is processed by the company's
3S software algorithm in real time, which
results in a 30 to 50 percent higher sensitivity than competing technologies, Mettler Toledo says.
In addition, Product Signal Suppression
technology virtually eliminates the incidence of false triggering by suppressing the
active and unwanted product signals often
produced by what the company calls the
"Product Effect" -- signals produced by
the products themselves, particularly highmoisture products and products that change
temperature during the production cycle.
The benefits to the user are lower running
costs and a dramatic reduction in product
waste.

According to Bob Ries, lead product manager of x-ray inspection and metal detection
for Thermo Fisher, limitations in conventional metal detection are typically the result of using only one or two frequencies to
detect any type, size or shape of metal inside
dry or wet products.
"The latest technological breakthrough,
however, has allowed manufacturers to find
metal types and sizes previously undetectable, bringing more predictability to the process," he says. "This innovation - multiscan
technology - is poised to revolutionize metal detection and food safety, eliminating the
need for manufacturers to compromise, and
reducing their risk of costly recalls."
According to Thermo Fisher, when tested
over a wide range of products, the multiscan
detector typically picked up foreign metal
objects that were 49 percent smaller in volume and, in the most extreme case, could
even detect metal up to 70 percent smaller
in volume.

Sanchez says another trend Mettler Toledo
has observed is that school districts and other education centers that provide lunches

have also become more aware of food safety
issues.

"A school district in Texas uses Mettler Toledo's Profile Advantage to inspect foods from
sandwiches to salads for metal contamination before they are distributed," he says.
"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."
