Oleic acid and melting point. Why Wagyu fat melts at a lower temperature.
That melt-in-your-mouth feeling when you enjoy Wagyu? Part of the secret lies in the temperature at which its fat melts.
“Melting point” is the temperature at which solid fat turns liquid.
While ordinary beef fat typically melts at around 40–50°C, Wagyu fat often melts at around 20–30°C.
This varies between animals and cuts, but fat that melts below body temperature contributes to Wagyu’s smooth mouthfeel.
One of the reasons for this difference is oleic acid.
Oleic acid is a monounsaturated fatty acid also found in olive oil. Japanese Wagyu, particularly Japanese Black cattle, tends to have a higher proportion of it in its fat. This balance of fatty acids helps lower the melting point, contributing to that delicate, melting texture.
When choosing Wagyu, it’s easy to focus on how much marbling we can see.
But the amount of fat is only part of the story. The quality of that fat matters too—and it’s another reason Wagyu is so enjoyable.
