Abstract
A method of manufacturing soy sauce comprises the steps of sampling a portion of a prescribed amount of raw soy sauce and simultaneously analyzing the concentrations of at least two ingredients of the sampled portion of the raw soy sauce, calculating the amount to be added of at least one controlling element in order to adjust the concentrations of the at least two ingredients to target values according to analytic results, and adding the calculated amount of the at least one controlling element to the prescribed amount of raw soy sauce. An apparatus for manufacturing soy sauce comprises a sampling mechanism for sampling a portion of a prescribed amount of raw soy sauce stored in at least one storage tank, and an automatic multiple analyzer for receiving the portion of the prescribed amount of raw soy sauce from the sampling mechanism and simultaneously analyzing the concentrations of at least two ingredients of the sampled portion of the raw soy sauce. The apparatus also includes at least one control tank operatively communicating with the storage tank for supplying at least one controlling element to the raw soy sauce in the storage tank, and a control mechanism for selectively o…
