Measuring the Color of Soy Sauce
Soy sauce, also known as soya sauce, is a staple ingredient in most Asian cuisine. It is commonly used by chefs to enhance the flavor of the dish. Traditionally brewed soy sauce uses the honjozo process (regular fermenting method) and has a clear reddish-brown color. It is well balanced in terms of flavor and aroma. Soy sauce which is produced chemically are darker in color with strong and unpleasant taste.
Both sauces post a big challenge for the food chemist to differentiate their color differences. For instance, light soy sauce can be difficult to judge as they are translucent and are easily influenced by factors such as background lighting.
