Suppliers offer an array of clean-label antioxidants
with various concentrations of active compounds. Usage
level depends upon the product formula, storage conditions
and desired shelf life.
" Antioxidants have the flexibility of being applied at
any stage of a process, " Senanayake said. " Liquid products
can be either oil- or water-soluble. Oil soluble antioxidants
can be easily incorporated into the oil phase of
the formulations. The powder form of antioxidants may
be preferred for certain formulations containing dry ingredients,
as they facilitate easier blending. "
Fernandez said, " Botanical extract solutions combine
ingredients that have different mechanisms of anti-oxidation
at various points of the oxidative chain, resulting
in enhanced efficacy through synergies to slow spoilage
and protect the substrate, thereby extending shelf life
and helping to reduce food waste. "
In addition to adding antioxidants to delay lipid oxidation,
it is often necessary to use specially treated nutrients.
This includes essential minerals that participate in
metal-induced oxidation.
" Manufacturers should
consider secondary shelf
life and the consequences
of packaging failures. "

" Providing a complete-and-balanced diet to pets
means that manufacturers include vitamins and trace
metals into pet food, " said Tayler Hansen, Ph.D., companion
animal nutritionist, Trouw Nutrition USA,
Highland, Ill. " Trace metals are highly reactive and have
a strong redox potential. They can oxidize other ingredients
like vitamins and fat, reducing product shelf life. "
Trouw Nutrition helps pet manufactures balance the
reactivity of ingredients with the nutritional needs of the
pet. This includes offering chelated organic trace minerals
to minimize reactions.
" The reactive trace metal is bound to a partner like an
amino acid, " Hansen said. " When this bond is strong, the
trace metal is less likely to interact with other ingredients
in pet food, which improves product shelf life. "

Leaders in Moisture Measurement & Control
non contact. instant. accurate.
With varying moisture content in raw materials, on-line NIR
measurement is a key tool in ensuring optimum efficiency
and quality control. The ability to measure moisture and
make process adjustments during the production cycle is
key.
Monitoring the moisture in the raw materials, controlling the
mixing/blending process and moisture of the feed not only
ensures the final product with consistent quality, but
will enable substantial savings to be achieved in the
production process. The user will know the levels of
moisture in the raw material and will be able to accurately
calculate the amount of moisture that needs to be added to
the mix to achieve the correct consistency of the product.
