Embodiment 1

[0036] The extraction rate of soluble nitrogen-containing compounds in the supernatant obtained in this example reaches 1.35%, which is 175.51% higher than that of the trypsin enzymolysis extraction of lentinus edodes soluble nitrogen-containing compounds in Comparative Example 1, which is higher than that of the comparative example 1 The extraction rate of soluble nitrogen-containing compounds in Lentinus edodes was increased by 28.57% in the ratio 2 of screw extrusion without protease enzymatic hydrolysis.

[0037] Example 2.

Embodiment 2

[0039] The extraction rate of soluble nitrogen-containing compounds in the supernatant obtained in this embodiment reaches 1.64%, which is 234.69% higher than that of the trypsin enzymatic hydrolysis extraction of lentinus edodes soluble nitrogen-containing compounds in Comparative Example 1, which is 234.69% higher than that of the comparative example 1. The soluble nitrogen extraction rate of the soluble nitrogen-containing compounds of Lentinus edodes was increased by 56.19% in ratio 2 by screw extrusion without protease enzymatic hydrolysis.

[0040] Example 3.

Embodiment 3

[0042] The extraction rate of soluble nitrogen-containing compounds in the supernatant obtained in this embodiment reaches 1.34%, which is 173.47% higher than that of the trypsin enzymatic hydrolysis extraction of lentinus edodes soluble nitrogen-containing compounds in Comparative Example 1. The soluble nitrogen extraction rate of the soluble nitrogen-containing compounds of Lentinus edodes was increased by 27.62% in ratio 2 only by screw extrusion without protease enzymatic hydrolysis.

[0043] In Examples 4-6, other edible fungi were selected, and experiments were carried out through the method of extracting soluble nitrogen-containing compounds of Lentinus edodes through screw extrusion combined with enzymatic hydrolysis of the present invention.

Abstract

The invention belongs to the technical field of edible fungus processing, and particularly relates to a method for extracting soluble nitrogen-containing compounds from edible fungi by combining screw extrusion with enzymolysis. The method includes the steps: (a) treating raw materials; (b) performing screw extrusion pretreatment; (c) performing enzymolysis; and (d) performing centrifugal treatment to obtain supernatant liquor of the soluble nitrogen-containing compounds and edible fungus residues. By combining modified wall breaking of screw extrusion with further proteinase enzymolysis, the advantages of modified wall breaking of screw extrusion and enzymolysis are combined, delicious substances in thallus of the edible fungi are effectively released, the extraction rate of the soluble nitrogen-containing compounds of mushrooms is increased, and the method is green and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of edible fungi processing, in particular to a method for extracting soluble nitrogen-containing compounds of edible fungi by screw extrusion combined with enzymatic hydrolysis. Background technique [0002] Edible fungus is recommended as one of the top ten health foods, not only has high nutritional and health value, but also has a unique flavor, which is favored by consumers. For example, Straw Mushroom is delicious and full-bodied, known as "put a piece, fragrant in one pot"; Pleurotus eryngii is named after "the fragrance is strong like almond, and the taste is as delicious as abalone"; wait. As one of the components expressing the unique umami taste of edible fungi, free amino acids account for 25%-35% of the total amino acids in edible fungi. Among them, the content of umami amino acids such as aspartic acid, glutamic acid, glycine, and alanine is extremely rich in edible fungi, especially in shiita...
