The invention discloses a composite dried collybia albuminosa sauce and a preparation method thereof. The preparation method comprises the following steps: (1) screening and cleaning dried collybia albuminosa; (2) soaking the cleaned collybia albuminosa; (3) draining the soaked collybia albuminosa; (4) mashing the drained collybia albuminosa to obtain collybia albuminosa pulp; (5) performing enzymatic hydrolysis on the collybia albuminosa pulp, regulating the pH value to enable the pH of the pulp to be 5.5, and then adding cellulase, wherein the enzymatic hydrolysis temperature is 55-60 DEG C, the enzymatic hydrolysis time is 1 hour; then adding papain and flavored protease, wherein the enzymatic hydrolysis temperature is 50-60 DEG C, and the enzymatic hydrolysis time is 2 hours; (6) performing enzymic inactivation on enzymatic hydrolysate; (7) filtering the enzymatic hydrolysis on which the enzymic inactivation is performed; (8) seasoning the filtered enzymatic hydrolysis: adding table salt, white granulated sugar, gourmet powder, I+G, yeast extracts, dried scallop quality, ethyl maltol, ginger powder, pepper powder and sodium benzoate to the obtained enzymatic hydrolysate in the step (7), and stirring the materials of the enzymatic hydrolysate, the table salt, the white granulated sugar, the gourmet powder, the I+G, the yeast extracts, the dried scallop quality, the ethyl maltol, the ginger powder, the pepper powder and the sodium benzoate to enable the materials to be dissolved; (9) thickening the dissolved materials obtained in the step (8); and (10) filling the thickened materials in bottles, and disinfecting the bottles with the thickened materials. According to the composite dried termitomyces albuminosus sauce disclosed by the invention, the enzymatic hydrolysis time is shortened, the energy consumption is reduced, the stability of products is improved, and the prepared composite dried termitomyces albuminosus sauce is safe, healthy and rich in nutrition.
