assignment

I want to reduce waste loss due to freezing.

Background of considering the introduction of rapid freezer

Regulations changed and we had to freeze horse meat, which caused a lot of waste and was a problem.

In the past, we used to serve horse meat raw to customers, but the health center regulations changed and we now have to freeze it at -20℃ for 48 hours or -30℃ for 18 hours to kill parasites. I did.

Therefore, before the introduction of rapid freezer, horsemeat was aged and then frozen in regular commercial freezers. However, horsemeat has a higher moisture content than other meats, so it will inevitably drip when frozen.

In addition, when thawing the food, the surface would change color, making that part unusable and resulting in waste, which was a problem.

At that time, I learned of the existence of rapid freezer that can minimize drips, so I consulted with Daybreak.

After actually doing a freezing test, I found out that rapid freezer is the most compatible because it can efficiently freeze large chunks of meat by blowing cold air all over it, so I decided to purchase it.

Effects after introducing rapid freezer

The waste loss of horsemeat has returned to the level when it was not frozen.

After introducing rapid freezer, the waste loss of horsemeat returned to the level that would be achieved without freezing.

This is because the quality of the product, which had deteriorated due to discoloration during freezing, has now almost completely disappeared.

Regarding the quality of frozen products, we have not heard from customers that the taste has changed.

However, as someone who cooks it, I feel that it has become a little softer, but I think that if the vacuum packaging method were improved, the quality of frozen food could be improved even more.

Future outlook

We would like to reduce waste loss during aging by introducing ice storage.

With the introduction of rapid freezer, we have been able to significantly reduce waste loss during freezing.

However, there is still a lot of waste loss during the aging process before freezing, so we would like to solve this problem by introducing an ice chamber in a special refrigerator.

We would like to continue to ask Daybreak to introduce the ice storage.
