Raw shirasu is conventionally a difficult product to distribute because of its rapid quality deterioration. Raw shirasu landed at the beach can only be tasted at the beach.
Proton freezing prevents deterioration and perfectly reproduces fresh baby sardines. This enables the distribution of raw baby sardines, which was said to be impossible in the past, and enables us to expand our sales nationwide. In addition, in recent years, the price of baby sardines has been unstable due to the uneven amount of landings, but storing them in proton freezer will help stabilize the price.
