煮干し / いりこ (Niboshi / Iriko)

Seto Inland Sea production has 100+ years of grading and curing tradition; Iyo-nada iriko is the gold standard in Japanese ramen kitchens.
Protein 60-70% dry weight; calcium 2,200–2,500 mg/100g; dashi extraction yield 25-35%.
Premium ramen broth bases, dashi packets, calcium-fortified functional foods.
Boiled-and-dried small sardines (typically Japanese anchovy, Engraulis japonicus) used as a dashi base distinct from kombu/katsuobushi. The Seto Inland Sea (especially Iyo-nada) is the primary production region, where 'iriko' is the local name. Niboshi-based dashi is the foundation of regional ramen broths (especially Tsukemen), miso soup in many Japanese homes, and increasingly export-grade premium dashi packets. Calcium content makes niboshi a target for functional food positioning.
