Next is waiting for the \u201cyoung\u201d meat, not yet suitable for eating, to mature. The number of days the fish will be rested depends on the size of the fish and the temperature. The smaller the cut and the warmer the temperature, the shorter the rest time. Generally the time is from 3-14 days.<\/p>\n

The tuna wholesaler may also decide on the aging period independently. There is no right answer for this aging period, and it is decided based on the experience of the sushi chef.<\/p>\n

This \u201cyoung\u201d fish not ready for consumption is a fresh, deep color but as it matures the color darkens, the fat is brought out and becomes a fleshy color. Proper care must be taken because if it\u2019s rested for too long, the color changes too quickly.<\/p>\n

As an aside, right after the tuna cutting show<\/a><\/span>, it has not yet aged enough to be delicious. The color is light, and the production of umami ingredients such as inosinic acid is not sufficient. This is a show for advertising purposes.<\/p>\n
