    • PURPOSE:To obtain a light-colored soy sauce having improved luster and color efficiently, by heating a raw stock of soy sauce to a given temperature as rapidly as possible, keeping the stock at this temperature for a little while, and quickly cooling the stock to a specific temperature or below. CONSTITUTION:A soy sauce stock solution consisting of a raw soy sauce for soy sauces, e.g. deep-colored, light-colored, low salt, white or TAMARI (sauce from refined soy) is heated to 90-130 deg.C, preferably 105-125 deg.C, as rapidly as possible with a plate type heat exchanger, etc., and the soy sauce stock solution is kept in the temperature region within 5min, and then cooled rapidly to 60 deg.C or below, preferably 45-55 deg.C. The cooling operation in this case is particularly important, enhances the luster and color stability of the product in the storage and further prevents the formation of sediments almost completely or entirely, and the resultant sediments are removed by the conventional stationary settling or filtering of the cooled stock solution with a filter aid, e.g. diatomaceous earth or perlite, to give the aimed product soy sauce.
