おから (Okara)

Japanese tofu industry's mass volume produces the cleanest, most consistent okara supply globally; specialty upcyclers have built export-grade processing infrastructure.
Dietary fibre 40-55% dry weight; protein 25-30%; isoflavone content carries over from soy.
Plant-based meat alternative ingredient, gluten-free baking flour, high-fibre meal-replacement products.
Insoluble fibre and protein residue from soy-milk and tofu production. Long treated as feed/fertiliser in Japan, modern upcycling has converted okara into a high-fibre, high-protein functional food ingredient — used in plant-based meat alternatives, gluten-free baking, fibre-fortified supplements, and increasingly in cosmetic exfoliating formulations. Aichi, Niigata, and the broader tofu production heartland produce the largest volumes; specialty processors offer dried, defatted, and protein-isolate grades. Marketed as an upcycling success story aligning with sustainability and zero-waste retail trends.
