Steps in the Koji-Making Process

Koji-making process starts with the selection and rinsing of a suitable grain, commonly rice, barley, or soy. The quality of the grain is critical; it should be without blemishes and of good quality to enhance the growth of Koji mold, Aspergillus oryzae. The grain is then soaked in water, varying from a few hours to overnight, before it is steamed. Steaming is preferable over boiling as it leaves the grains intact and ensures better mold penetration. Once the grains are cooled to room temperature, they are inoculated with Koji spores through a process known as 'tane-koji.’ This master seed, a mixture of fungal spores and rice flour, is spread uniformly over the steamed grains to minimize clumping and promote even mold growth. To ensure Koji's optimal growth, a temperature between 85 to 100 degrees Fahrenheit and a humidity level of at least 70% is maintained. Considered the most crucial phase, the incubation period typically lasts for 36 to 48 hours. During this period, the grains are left to ferment, becoming covered in a fine, white mycelium. The Koji mold's enzymes break down the grains’ starches into sugars, proteins into amino acids, and lipids into simpler fatty acids. This biochemical process gives rise to the unique flavor and aroma associated with Koji. After the incubation, the Koji is ready to be harvested. Harvest involves reducing the grain’s temperature to stop further growth and drying it to prolong shelf life. This fine white mold that coats the grains, the Koji, is the end product used to make several traditional Japanese ingredients such as miso, soy sauce, and sake. Understanding the intricate process of Koji production is vital as each step influences the final product's quality.
