The invention discloses a production method for
brewing mushroom soy sauce. According to the method, 30-35% of
mushroom legs (dried mushrooms), 35-45% of soybeans and 25-35% of wheat in a
mass proportion are adopted as raw materials for
brewing via basic technologies of making
yeast via a traditional method and natural
fermentation. The method includes the steps of
raw material treatment, sterilization,
yeast making,
fermentation, oil spraying, airing, preparation and blending, sterilization before filling, and the like. The
mushroom soy sauce prepared by the method is 1.142g / 100mL in AN (
amino acid nitrogen) content and 35.12g / 100mL in soluble salt-free
solid content, and reaches special-grade standards;
bioactive substance lentinan reaches 0.245g / 100mL, and
Fe content is about 22.83mg / 100mL; total content of
free amino acid in important flavoring materials is 4.78mg / 100mL and higher than that of ordinary soy sauce by 1.4mg / 100mL, and product yield is up to 86.6%; the mushroom soy sauce is nutritional, health caring and delicious in taste.
