sive, stable and concentrated protein source, " Hubbard
said. " In the current market, it would likely be impossible
to find a sustainable and cost-effective alternative
to animal-based rendered proteins for the production of
finished kibble. While it is possible to use other sources
of protein, such as high-protein vegetables or legumes,
in pet food formulations in the place of rendered meals,
doing so is not currently economically viable at scale.
Another drawback to alternatives to meat-based proteins
is that they do not have the same nutritional benefits
as meat-based proteins and are less digestible. "
Meat-based rendered ingredients, for example, are
considered complete proteins. This means they provide
all the essential amino acids pets need at the correct ratios.
Most plant proteins are not considered complete, as
they either lack certain amino acids or do not contain
them in sufficient quantities.
Safety first
" Anyone avoiding rendered products for reasons of quality,
nutrition or reputation should take another look, "
Meeker said. " Rendered ingredients are not only sustainable,
but also safe due to the enforcement of strict
safety guidelines. "
Mary Landis, industry sales manager for feed, grain
and oils, Foss North America, Eden Prairie, Minn., said,
" Both bench-top and on-line near infrared (NIR) analysis
is used to meet and verify specifications. "
Such NIR analysis is an accurate and rapid method
for quantitative determination of the major constituents
in most types of food and agricultural products, including
pet foods. It's commonly used to help screen materials
for quality assurance purposes. The NIR equipment
can also give an approximate reading for protein, moisture
and fat content.

Integrated Proteins specializes in poultry meals, but
also supplies fish meals, specialty animal-based protein
meals and other specialty ingredients. The company uses
a proprietary process to refine already-rendered meals
in order to improve their quality and safety prior to inclusion
a finished pet food.
" Despite renderers' reasonable best efforts, rendered
materials contain foreign matter inherent in the rendering
process, " Hubbard said. " We use selectively applied
separation techniques to remove foreign matter and
other non-digestible particles. This process makes meals
safer for pets and more digestible by removing what
should not be in the meal without compromising the
protein levels or overall nutritional profile of the meal. "
Tomra Food, Madrid, Spain, markets optical sorting
technologies to renderers to maximize efficiency and
minimize waste. Rendered ingredients for pet food is a
higher-value use of meat and bone materials than rendering
for alternatives, such as fuels or fertilizer.
" But achieving higher commercial values requires
higher standards, necessitating the detection and removal
of the smallest fragments of foreign material
from the product mix, " said Lars Povlsen, global sales
manager of proteins, Tomra Food. " In addition to the
economic benefits, improving rendering efficiency is
also good for the environment. As the world moves
toward a circular economy, with the urgent need to reduce
greenhouse gas emissions and landfill waste, it is
worth remembering that rendering is essentially recycling.
This is important because approximately 50% of
the animal is considered inedible by human consumers
and, without rendering for other uses, would otherwise
be wasted. "
Such optical sorting technologies assist with identifying
the foreign materials often accidentally introduced
