ELABORATION PROCESS
The first step is to prepare the soybeans and wheat to make koji. The soybeans are steamed until soft enough to be easily squashed between the thumb and middle finger, but firm enough to hold its shape. The wheat is roasted on hot sand until it achieves a brownish-brown color and a very characteristic aroma. It is then roughly ground, like cracked wheat. Soy and wheat are mixed and koji seed is added.
The role of the koji seed is to activate fermentation. During its growth, the koji seed produces proteolytic, lipolytic and amylolytic enzymes that convert proteins, fats and starches into simpler and more easily fermentable substances.
Fermentation is a complex process that involves molds, yeasts, and lactic acid bacteria. The enzymes released by koji convert starches into simple sugars. Natural yeast, including Saccharomyces rouxii, converts these sugars into alcohol and esters, which give soy sauce its distinctive aroma. Other enzymes, particularly diastase, break proteins down into amino acids. The lactic acid bacteria then spread, producing lactic acid.
