A new device for
detecting woody breast
The system uses machine vision to detect the condition in
breast meat fillets.
AUSTIN ALONZO

U

sing the power of machine vision, a new
device that may soon be on the market can
help poultry processing plants sort out chicken
breast meat exhibiting signs of woody breast syndrome
from normal meat.
Seung-Chul Yoon, Ph.D., a research electronics
engineer in the Quality and Safety Assessment Research
Unit at the U.S. Department of Agriculture-Agricultural
Research Service's (USDA-ARS) U.S. National Poultry
Research Center in Athens, Georgia, developed a system
that uses a machine-vision camera and software platform
to identify breast meat fillets exhibiting signs of the
myopathy. Yoon presented his research on November 6 at
the 2018 Poultry Tech Summit in Atlanta.

How the device works

Austin Alonzo

Woody breast syndrome is a muscle disorder that
causes the breast meat to be abnormally hard and
rigid. Although the exact cause is not well understood,
the myopathy is associated with large, fast-growing
broilers. Information on the incidence rate of this
myopathy is limited, but available reports have shown
that it may occur in 5 to 40 percent of breast fillets
from fast-growing hybrids. Fillets with the myopathy
are being sorted manually based on subjective criteria,
so Yoon set out to develop an objective method for
finding and sorting out woody from normal breast
meat fillets during processing.
The device is based on the basic concept that
woody breast meat is rigid and doesn't bend easily,
whereas normal breast meat is pliable. Using this

principal, Yoon and his team developed a system that
uses machine vision and a custom computer algorithm
to measure how much a breast fillet bends and to signal
whether it's woody or normal.
The system uses a single camera placed at the end of
a conveyor belt, where it can capture a side view of the
fillets falling and analyze how much the meat bends as it
falls off the conveyor. If it bends to a certain degree, it's
identified as a normal piece of chicken. If it doesn't bend
to a pre-set threshold value, it's sorted out as a woody
breast. The vision device runs at about 200 frames per
second and up to the maximum line speed of 40 meters
per minute, so it is able to keep up with current production lines in the U.S.
