[0027] The preparation method of a kind of lotus seed mud provided by the invention comprises the following steps:
[0028] Step 1: The white fungus coarse powder that has passed through the 60-mesh sieve is pulverized by an airflow ultrafine pulverizer, and then passed through a 400-600-mesh sieve to obtain the Tremella ultrafine powder, and the Tremella ultrafine powder and distilled water are 1~3:5~ The mass ratio of 15 is naturally swollen for 10 to 20 min after stirring and mixing, and then heated in a water bath for 10 to 20 min to obtain Tremella gel solution;
[0029] Step 2: After blanching the cut papillary dark brown protrusions of fresh lotus seeds for 2~3min, cook at 90~120℃ for 20~40min, then add color-retaining agent for beating, and then add citric acid to adjust to The pH value of the slurry is 4.0~5.5 and continue beating to obtain lotus seed pulp;
[0030] Step 3: add cellulase to the lotus seed pulp in step 2 for enzymatic hydrolysis for 7~9h;
[0031] St...

[0052] A preparation method of lotus seed mud, comprising the following steps:
[0053] Step 1: place the dried tremella in a plant pulverizer for preliminary pulverization, and pass through a 60-mesh sieve to obtain a white fungus coarse powder, and pass the tremella coarse powder through a 60-mesh sieve through an airflow ultrafine pulverizer (the airflow pressure is 0.6MPa). , the feeding speed is 90 kg / h)) after pulverizing, cross a 400-mesh sieve to obtain Tremella ultrafine powder, stir and mix the Tremella ultrafine powder and distilled water at a mass ratio of 1:5 and swell naturally for 10min, then at 70 Under the condition of ℃, heating in a water bath for 10min makes it completely dissolved to obtain Tremella gel solution;
[0054] Step 2: After blanching the cut papillary dark brown protrusions of fresh lotus seeds for 2 minutes, cook at 90°C for 20 minutes, then add 0.15 g / 100 mL of erythorbic acid for beating, and then add citric acid to adjust the pH of the slur...
