Domestic black-rice cultivation provides traceability and arsenic-control profiles unavailable in mass-volume Asian supply.
Anthocyanin (cyanidin-3-glucoside) 100-300 mg/100g dry; protein 8-10%; bran-derived dietary fibre elevated.
Anthocyanin FFC supplements, kuromai-cha for export retail, premium blend rice.
Pigmented ancient rice variety with anthocyanin-rich black bran. Japanese cultivation centres on Hokkaido, Akita, and Niigata under FFC and functional-food positioning. The seed coat carries cyanidin-3-glucoside concentrations 10-50× higher than common white rice. Used as a 5-10% blend in white-rice cooking (gives a purple tint), in onigiri, and as a stand-alone supplement / kuromai-cha (black-rice tea). Distinct from kuromame (black soybean) and existing white-rice / mochigome entries.

Hokuren Federation of Agricultural Cooperatives
ホクレン農業協同組合連合会
Hokkaido's federation of agricultural cooperatives, founded 1919. Aggregates supply for over 90% of Hokkaido's agricultural and dairy production: azuki beans, hokkaido scallops, dairy, beet sugar, soy and grain products, and increasingly potato- and beet-derived functional ingredient feedstock. The export division manages overseas sourcing relationships for fresh, frozen, and processed Hokkaido-origin agri-products. The aggregation tier means many overseas buyers reach individual Hokkaido producers via Hokuren first.
