commercial natto
Rich in vitamin K2 and nattokinase enzyme; provides complete plant-based protein and isoflavones from fermented soybeans. The fermentation process enhances bioavailability of minerals and produces beneficial probiotics.
About
Natto is a traditional Japanese fermented soybean product made by inoculating cooked soybeans with Bacillus subtilis (nattō-kin), a beneficial bacterium, and allowing them to ferment for 24 hours at controlled temperatures. The result is a sticky, ammonia-scented preparation with a distinctive umami flavor and characteristic stringy, mucilaginous texture created by bacterial polysaccharide production.
Commercial natto is typically sold in small styrofoam containers with attached packets of tare (sauce) and mustard, designed for immediate consumption or refrigeration. The fermentation process produces nattokinase, an enzyme with notable biochemical properties, and increases bioavailability of soy nutrients. Natto's flavor profile is assertively earthy, slightly sweet, and pungently aromatic, with variations depending on fermentation duration and bacterial strain.
Culinary Uses
Natto is most commonly consumed in Japanese cuisine as a breakfast or rice topping (nattō gohan), where it is mixed into hot steamed rice with soy sauce and mustard. It also features in sushi rolls (nattō maki), pasta dishes, omelets, and vegetable preparations. The sticky texture and strong umami character make it a potent flavoring agent—small quantities can significantly enhance broths, noodle dishes, and vegetable sides. Natto is typically stirred vigorously before serving to maximize its characteristic stringiness. Outside Japan, it has gained popularity in contemporary fusion cooking as a umami element and textural accent in non-traditional applications.
