Quality evaluation of the Atlantic Bluefin Tuna

Quality evaluation

3 factors that determine value

1 : Freshness
2 : Fat
3 : Colour


How to check freshness.
Tuna that has been frozen before rigor mortis will shrink.
Japanese said “CHIJIMI”.

Freshness also affects how much colour can be kept.


How to check fat.
There are 2 factors.

1 : Fat amount.
The height of fat from the skin.

2 : Fat quality.
The finer fat is the better with texture.


Needless to say.
Beautiful scarlet colour.

All of this affects the price of tuna.
The last is the taste of sushi shokunin.
