How fat level, feed, and breed shape grilled beef flavor
What it found
More marbling in grilled beef meant stronger beefy flavor, more tenderness, and higher levels of certain fats.
Wagyu beef scored higher for flavor and tenderness than Angus beef when fat levels were matched.
What they found
Fat level and flavor
As the amount of fat inside the muscle went up, grilled beef flavor, dairy fat notes, and sweetness increased. Sourness and a dry mouthfeel decreased.
Wagyu versus Angus
When the fat content was matched, Wagyu samples had stronger flavor and were more tender and juicy than grass-fed Angus samples. Differences between grass-fed and grain-fed Angus were small once fat was above about 5%.
Tenderness and juiciness
Both tenderness and juiciness rose as the fat inside the muscle increased. These traits also matched up with standard lab measurements of how much force it took to cut the meat.
Aroma and taste compounds
Flavor differences noticed by the trained tasting panel lined up with changes in aroma chemicals and other flavor compounds in the meat.
Fats that rise with marbling
Certain unsaturated fats, including vaccenic, oleic, and rumenic acids, went up as the marbling level increased. The authors describe these particular fats as having potential health benefits.
What the authors conclude
- They found that the amount of fat inside the muscle is a key driver of flavor, tenderness, and juiciness in grilled beef.
- They note that Wagyu cattle produce meat with stronger flavor and better texture than Angus cattle when the fat content is the same.
- The authors point out that higher marbling also raises the levels of certain unsaturated fats they consider potentially beneficial.
How it was done
The authors wanted to understand how the amount of fat inside the muscle, the type of feed, and the cattle breed change the taste and chemistry of beef from Southern Australia.
They tested 42 grilled beef striploins from different cattle types typical of Southern Australia. These included grass-fed Angus yearlings, grain-fed Angus steers, and grass-fed Wagyu heifers. A trained tasting panel evaluated the meat, and the researchers measured its chemical makeup.
What it can’t tell you
- We summarised it from the abstract only.
- This work looked at taste, texture, and chemistry rather than health outcomes in people who eat the meat.
- It cannot show whether the higher levels of certain fats in well-marbled beef lead to any actual health effects in shoppers.
