Yellowtail Fish
First, we would like to introduce a couple interesting facts about the yellowtail.
The yellowtail is famous for having different names, based on the sizes.
The grown and largest of the fish is called the yellowfish, but the smaller ones have a different name.

|---|---|
| from 20cm | Wakashi |
| from 40cm | Inada |
| from 60cm | Warasa |
| from 80cm and on | Yellowtail |
As listed, the name of the yellowtail varies on the size of the fish.
In the Kansai region it has been called Hamachi, but recently, it is the name given to farmed, smaller fishes.

Rejoice
Yellowtail frozen with liquid based freezer.
As seen in the picture, the freshness of the flesh is completely different.
While surprised with the difference in appearance, I also sampled both contents.
The slow frozen yellowtail had changed in taste, and did not taste good at all. The reason for this deterioration is because with the normal method of freezing, the cells in the inner core of the ingredient is destroyed, and flavor contents are lost.
For the liquid frozen content, there was absolutely no drip outflow, and the appearance and texture did not change from prior to being frozen. I felt that this was by far the best frozen fish I have ever had.
The difference can be clear with the picture, but when actually sampling the tested product, the liquid frozen content tastes much better. Therefore, when freezing fishes like the yellowtail, the Liquid based Freezers are the best.
Additionally, the liquid based freezer, Re・Joice Freezer is said to be the best for freezing fisheries and seafoods. Therefore, for fisheries and seafood such as the yellowfish, the Re・Joice freezer and other liquid based freezers are recommended.
However, the results of how each ingredients correlate with flash freezers interchange with the types. Therefore, for those who are interested in flash freezers, the Mita Exhibition Hall provides test freezes for ingredients brought in by customers. Multiple foods can be brought in for testing, and the prices and freezing ability of different brands can be compared.
In this website, out of the liquid based freezers, the Re・Joice Freezer is recommended.Information on this highly recommended liquid based freezer is available in the article below.
