The present invention relates to a mutant strain of Aspergillus sojae with an enhanced protease activity and a preparation method of a natural taste enhancer using the same. More specifically, the present invention relates to the mutant strain of Aspergillus sojae with an enhanced protease activity is obtained by selecting a strain with high protease activity and treating it with N-methyl-N′-Nitroso-N-nitrosoguanidine (NTG) and inducing a mutation through irradiating, and a preparation method of a natural taste enhancer using protein hydrolysate obtained by hydrolyzing the protein sources with their cultures.
