Our Newest Challenge – First in Japan! Underground Seawater Nori -
Before putting nori into the dryer, we use 100% underground seawater to clean our nori. Seawater, which has been traditionally used to clean nori, contains more than a few impurities. It is also unstable in that the water quality fluctuates depending on the weather. In that respect underground-seawater is almost aseptic and the water quality is stable. This significantly contributes to the hygienic improvement of nori quality. Underground seawater has less dissolved oxygen and more amino acids, so nori processed with the water is considered to have more umami and taste better.
What is underground seawater?
Underground-seawater is naturally purified seawater that has permeated underground. Filtered through tidelands and sandy soils, It is virtually free of microorganisms and is stable throughout the year. It is also called underground permeated seawater.
