FORMULATION

"In dry pet foods, the water activity is low enough not to
be much of a concern for shelf life. In canned pet foods,
the water activity is important not only for shelf life and
palatability, but also because of syneresis or separation
issues that can occur if there is variable water activity
without an effective stabilizing system in place."

activity are necessary

product quality.

Right: Reaching the
desired moisture level
at the end of a production line requires
moisture data for all dry
ingredients and at each
step of processing.

Moisture measurement is critical in all aspects of the
materials process. Thus, manufacturing companies are
constantly adjusting moisture to maintain the quality of
their product. Advances in real-time sensing, data collection, and data analysis and interpretation help to determine the characteristics of the materials prior to processing, providing process efficiency and optimization.
The first step for pet food manufacturers to manage
water activity properly is to check it frequently and provide feedback to production managers if product is not
meeting specification. This can be caused by non-optimal equipment settings or by variability in ingredients.
Spot checking incoming ingredients for changes in
water activity can also be helpful to identify when variability in ingredients could cause finished product to be
out of specification.
"The water activity of the product over time will be dictated by the combination of packaging and storage conditions," Carter said. "So, understanding how quickly the
water activity will change to unsafe levels in the current
packaging will allow manufacturers to determine if their
current package is sufficient or if a lower cost packaging
could be utilized. This can be done through modeling
when the package moisture barrier properties are known."

Moisture measurement during the production of animal feed is desirable at numerous stages throughout the
manufacturing process.
"With varying moisture content in raw materials,
on-line near-infrared (NIR) measurement is a key tool
in ensuring optimum efficiency and quality control,"

"Managing water
activity is the most
important monitoring
tool that can be used
for pet food safety
and quality."
Brady Carter, Ph.D., Neutec Group, Inc.
Hammond said. "The ability to measure moisture and
make process adjustments during the production cycle is
key. The MoistTech Online sensors can be installed into
any hopper, silo, material line, belt or screw conveyor
and the moisture results are displayed on a color touch
screen or output on any of our many signal options."
Animal food that is too wet or too dry can result in
the loss of a manufacturer's time and money, as well as
impact the quality of the end-product.
"Stable, fixed moisture levels, however, ensure that animal food products maintain consistency, and that product
waste is minimized," Hammond said.
