Nearly 10 key compounds have been detected in wagyu beef, which contribute to the delicacy's alluring aroma. Presence of unsaturated fatty acids also enhances aroma.

‘About 10 new odorants identified in wagyu beef and also the presence of a specific unsaturated fatty acid makes the beef alluring.’

Considered by some to be the champagne or caviar of beef, Waygu is one of the rarest and most expensive meats in the world. It comes from Japanese Black cattle which accounts for 95 percent of Wagyu and three other species raised in Japan. 




The meat's distinctive marbling, juiciness and succulent taste are enhanced by its sweet aroma, known as "wagyuko," that has been compared to coconut or fruit. In recent years, scientists have been trying to nail down what makes Wagyu aroma distinctive from other types of beef.
In one study, researchers found that one particular compound appeared to have an important influence on the meat's aroma. But the samples used in that experiment were not cooked at the optimal temperature.
To get a better sense of which odorants are responsible for Wagyu's aroma, Satsuki Inagaki and colleagues decided to try a different approach.
The researchers conducted an aroma extraction dilution analysis of Matsusaka-beef (a kind of Wagyu ribeye) and grass-fed Australia beef (loin).

Several Wagyu compounds were also found in the Australian beef aroma. However, the researchers say they likely don't smell alike because of the differing amounts of these constituents in the meats.

The researchers say that this study not only clarifies which compounds are the main odorants in cooked Wagyu, it also helps confirm that particular types and amounts of unsaturated fatty acids in the beef play a key part in this aromatic process.
