Documented Beef Quality

40 years on, science still backs leading beef brand

 

by Miranda Reiman

For all the talk of fads and changing consumer habits, this remains: what makes a good beef eating experience today is the same as it was 40 years ago.

But a new research report details – and updates – the science that still defines the ideal carcass.

“They continue to research it and we continue to see the same results, that more marbling is better,” says meat scientist Phil “Dr. Phil” Bass.

The 25-page literature review he recently authored for his company is titled, “The scientific basis of the Certified Angus Beef ® (CAB®) brand carcass specifications.” It combines findings of 127 published scientific articles to help explain the technical basis for the brand’s third-party-evaluated criteria.

Those include everything from a “10- to 16-square-inch ribeye” to “no dark cutters.”

It all starts with cattle that are at least 51% black-hided, as a way to identify “Angus-type cattle.”

“It’s amazing the amount of data that’s out there that just shows Angus cattle in general will tend to have better carcass quality,” Bass says, referencing work as old as 1982 and as current as 2014.

“However, merely having an Angus phenotype is only a first step in qualifying for the CAB brand; 10 carcass traits must be evaluated and confirmed within specification prior to formal certification of the carcass,” the paper notes.

Marbling is the No. 1 reason cattle don’t qualify, as that score not only must be Modest or higher, otherwise known as upper two-thirds Choice, but also needs to be evenly distributed with medium to fine texture.

Several studies from Texas and Kansas to Colorado point out the role marbling plays in increasing palatability measures: flavor, juiciness and tenderness.

“Beef with a higher amount of marbling that is known to originate from a grain-finished management system has been described as having a desirable, buttery flavor,” the paper reports, also noting how even distribution influences tenderness.

Not only does the fat melt during the cooking process and help “lubrication,” but also “the less dense marbling dilutes the amount of muscle fiber bundle and thus accounts for an easier bite mechanically.”

Fat that melts during cooking results in “consistent and uniform distribution of perceived juiciness.”

The white paper covers everything from the logic for carcass sizing measures to specifications designed to eliminate defects.

 

Bass says precision and accuracy in meat science have improved as tools for cooking and measuring attributes like color have as well, but the science still proves the late 1970s specifications are just as relevant in 2016.

“We continue to see an increase in quality beef at the packing level,” he says. “That means the farmers and ranchers are doing their job, but I would encourage continued focus and trying to hit more ideal sizes, not just bigger sizes.”

Trying to eliminate stress, selecting for docility and “making sure that the animal is well finished but not over-finished” help avoid discounts.

What’s good for the consumer will bolster profits for the producer, Bass says.
That hasn’t changed either.

More Than Steak and Potatoes

Yesterday’s steak and baked potato is today’s beef brisket from the restaurant downtown. The food scene is changing, driven by a new age of consumers who want more. They seek new flavors and attributes on the packaging, but still expect beef to taste great.

2022 Was as Predicted

2022 Was as Predicted

If there was a lesson in 2022, it was that the beef market is very sensitive to declines in quality grade, as evidenced through price signals. It’s the first time in recent history where we’ve gone backwards — albeit ever so slightly — and customers are telling us they have unfulfilled demand. That’s reflected in the premiums paid, and that’s saying something after two years of extremely high premiums.

Growing Marketability

Growing Marketability

Advertised as the “Best Angus Beef” and “If it’s not Certified, it’s not the Best,” Certified Angus Beef’s reputation claims elite category status. To remain in that position, the brand must continue to deliver on that promise as customer expectations of quality evolve.
