FORMULATION
To achieve the desired " flowable gravy " for shredded or
soupy wet pet food products, Bartley said, " binding ingredients
are added to improve the impact the cooking process
has on texture, and ensure the texture stays stable throughout
retort. "
Balchem offers encapsulated calcium lactate and sodium
alginate to aid in water binding and reinforce protein structure,
increasing firmness and improving handleability.
Rough edges
Clearly, achieving the correct product texture is no small
undertaking. Processors face both ingredient and production
challenges along the way.
" Some of the common challenges are the spectrum of
allowable ingredients, target nutrient levels (moisture, fat,
protein), the shape of pet food, labeling, and the type of
equipment and processing conditions used for manufacturing, "
Bartley said. " Many of these challenges are related
and they all manifest themselves differently depending on
the type of product being made. "
As the number of pet food and treat SKUs grows, processors
are posed with increasing ingredient limitations
to create cleaner, more natural, sustainable and, generally,

longer periods of time to deliver consistent quality.
" Glycerin and other types of humectants are important
ingredients in semi-moist products to maintain a chewy
texture while also controlling water activity to optimize
product quality and safety, " McCarthy said.
Mason pointed out the use of gums can also bind water
and improve flowability, helping the product contain
more moisture while lowering water activity. He suggested
" a combination of proteins with grains/legumes to impart
flexibility and allow the proteins - once dried and utilized
humectants - to retain moisture, but still have low water
activities for acceptable shelf-life. "
Oil binding ingredients can also facilitate productive
shearing during processing. For semi-moist pet food and
treats, Fiberstar's Citri-Fi ingredients work to bind both oil
and water and remain thermally stable, ensuring the product
does not dry out prematurely.
Citri-Fi ingredients can bind up to 10 times their weight
in water and eight times their weight in oil, allowing them
to be incorporated in extruded, baked or semi-moist pet
food and product formulations at low usage rates.
Starches and gums also play a key role in determining
the textures of wet pet food products, McCarthy said.
" Wet foods have very high moisture contents and will
utilize a combination of protein sources and starches/gums
to control product firmness and resilience, " Mason said.
" Pâté-style foods are expected to maintain a loaf-like appearance
and have enough body to maintain this shape,
while chunk and gravy should have firmer meat pieces and
a flowable gravy. "

higher-quality products.
" Ingredient restriction is a common challenge in achieving
the right texture, " Liu said. " More often than not, the
formulator is only allowed to use certain ingredients to
deliver specific free-from claims. In addition, the cost, the
order of ingredients in the ingredient statement, as well as
guaranteed analysis are also challenges because of the ingredient
restriction. "
" Using the right starch,
flour, protein or gum in
the right application
can help significantly
in achieving the
right texture. "
Patrick Luchsinger, Ingredion Incorporated
Choosing the right processing aid - and determining
the appropriate amount to be included - is crucial for
product success.
" One of the challenges to achieving the right texture is
incorporating oil into the formula, which can result in process
challenges and separation during shelf life, " Lundberg
said. " On the other hand, not adding enough oil into the
system will cause the pet food to dry out too quickly. "
