flash freezing demo Ayu

This time, we conducted a demonstration experiment using "Ayu"!

In this article, we reported on the results of ayu frozen using the Artlock Freezer and returned to customers for tasting and sensory evaluation.

Handling river fish (freshwater fish) is considered to be one of the most difficult types of fish, and if you leave them unattended after tightening them or handle them incorrectly during frozen storage, thawing, or after thawing,

It will immediately begin to emit a fishy odor, leading to a decrease in product value!

The Artlock Freezer we used for freezing is rapid freezer that received feedback from customers that `` I didn't notice any internal odor even after freezing and thawing.''

We conducted an experiment to find better conditions for pretreatment, freezing, and thawing using the Artlock Freezer, which is capable of freezing ayu with high commercial value and no fishy odor.

"We want to deliver our products to consumers without any problems in terms of hygiene or aroma, even after the process of freezing, storing, and thawing."

This is the result of an experiment conducted jointly with a customer who has this idea and researched the process of freezing, storage, and thawing!

The customer who requested this time sent us a live young sweetfish by mail.

ice tightening

When we tried a special processing method discovered through joint research regarding the process of freezing after ice tightening, we were able to improve the fishy odor even more than with normal freezing!

If you would like to know more about our joint research, please contact us!

freezing pattern

1. Freeze raw food
2. Freeze after special treatment ①
3. Freeze after special treatment ②

Vacuum after freezing

If the fins break, the appearance will change and the product value will decrease, so we vacuumed the fins at 95% to prevent them from breaking!
For vacuum storage, we use high-barrier (low oxygen permeability) vacuum bags that allow for the highest quality frozen storage.

Conclusion

This time, we reported on the results of a freezing and thawing experiment on ``Ayu.''

We tested three freezing patterns: one that freezes immediately after being iced, and one that freezes after undergoing special processing.

As a result of this experiment,

[Pattern 1 (immediately after freezing)] The freezing time of the ayu was 15 minutes!

[Pattern 2 (immediately after special treatment ①)] The freezing time of Ayu was 20 minutes!

[Pattern 3 (immediately after special treatment ②)] The freezing time of Ayu was 20 minutes!

Because both patterns use young sweetfish, they are small in size and can be frozen in a relatively short time.

From our customers,

​``Ayu frozen in Artlock has less fishy odor and is of much better quality (compared to regular freezing).''

We received feedback like this!
It seems that when frozen with Art Rock, there was no odor of internal organs.

In addition, young ayu is an ingredient that can be enjoyed for its beautiful appearance by cooking it whole, such as grilled with salt or in tempura.

By freezing the fish in the Artrock freezer used in the experiment, it is possible to easily freeze the fish while preserving its shape, allowing it to be delivered to customers without reducing its product value.

In addition to conducting demonstration experiments, the Daybreak Lab team, like this time, also conducts joint research based on the wishes of each customer.

Please take a look at this experiment and if you have any concerns or improvements you would like to make regarding the freezing, preservation, and thawing of foods, please contact us!
