Features of the "Serious Clams Sakamushi" Made by Clam Professionals

✓ Uses large domestic clams from Aichi Prefecture's Atsumi Peninsula

✓ Clams, with thorough quality control, are vacuum-packed. The original umami of the clams is locked in without loss.

✓ Easy to prepare, no need for salt removal or sand removal. Add a dish to your table with no hassle.

Until now, there have been very few authentic retort-pouched clams sakamushi products on the market. The biggest reason for this is that the unique "retort odor" generated by high-temperature, high-pressure sterilization compromises the delicate umami of the clams.

Here are three points of dedication made possible by clam professionals.

1. Original Umami of Ingredients Through Vacuum Packaging Method

In general preservation processing, umami components tend to be lost along with moisture.

Koryo Suisan adopted a vacuum packaging method through repeated trials to maximize the dashi flavor and texture of the clams. The rich aroma that spreads the moment you open the bag and the umami that overflows with every bite have been achieved.

Furthermore, Aichi Prefecture is known as one of Japan's leading clam production areas.

The clams, raised in the sea rich in plankton nurtured by Mikawa Bay and Rokujo Lagoon, are large and thick, almost bursting out of their shells.

This sakamushi has no retort odor and can be stored for a long time.

2. Safety Through Thorough Quality Control

Koryo Suisan thoroughly manages its clams using its own underground purified seawater facility.

By circulating clean seawater in a low-temperature environment maintained below 15 degrees Celsius, the risk of bacterial growth is suppressed. Only clams that meet quality standards are used.

3. Easy Preparation, No Salt or Sand Removal Needed. Add a Dish to Your Table with No Hassle.

This product does not require the hassle of sand removal or salt removal and can be enjoyed immediately after taking it out of the bag.

Simply warm it in the microwave. Authentic taste brought to your home.

Preparation is very simple.

By warming it in the microwave, you can create authentic clams sakamushi that tastes like it's from a specialty store.

It features a presence that overturns the image of ordinary instant foods and a juicy taste without any gaminess. It's finished as a "gourmet sakamushi" that allows you to enjoy even the clam broth.

It can be used not only as a dish for busy days but also as a snack with drinks or as a dish for entertaining guests.

Background of the Development of "Domestic Clams Sakamushi"

CEO Amano decided to develop this product with the desire to "encounter delicious sakamushi." After eating numerous retort-pouched foods and repeating trial and error, the technology arrived at allows customers to enjoy the original taste of clams while also being storable at room temperature for one year.

This project aims not only for product development but also to pass on the region's marine blessings and fishing culture to the next generation.
