The invention discloses a method for brewing composite selenium-enriched mushroom nutritious soy sauce. The method takes mushroom leftovers to partly replace soybean cakes for making starters and hydrolyzes the other part of the mushroom leftovers through proteinase; then the hydrolysate solution and the starters are mixed round and are fermented so that the rich protein, amino acid, flavor developing ribonucleotide, mushroom amylase and vitamins can thoroughly enter the soy sauce mash; and active slenium ferment rich in organic selenium is added into the soy sauce mash in the post-maturation process. A small amount of aroma-enhancing substances like ethanol and ester are produced during the fermentation process and the slenium ferment is totally autolyzed in the soy sauce mash. In this way, characteristic high-quality soy sauce can be prepared, which is rich in biologic selenium, amino acid, ribonucleotide, mushroom amylase and microelements and has the unique flavor of mushroom. Meanwhile, the method is good for recovering mushroom leftovers, thus reducing environment pollution and saving a large amount of soybean material.
