Embodiment 1
[0023] Mulberry fast biological degumming process, its steps are as follows:
[0024] (1) Preprocessing:
[0025] The mulberry bark that is picked is carried out pretreatment, and processing technology is: tea saponin 4g / L, time 3h, temperature 80 ℃, bath ratio 1:18;
[0026] (2) Microbial treatment:
[0027] Bacillus licheniformis, Bacillus subtilis, and EM bacteria are prepared according to the quantitative ratio of 1:0.2:0.5 to make a composite bacterial agent;
[0028] Spray the pretreated mulberry bark evenly with bacteria agent, ferment at 38°C for 8 hours, quickly raise the temperature to 45°C and maintain it for 2 seconds, then quickly cool down to 39°C and continue to ferment for 3 hours. After the fermentation is over, wash it with warm water;
[0029] (3) Enzyme treatment:
[0030] Equipped with enzyme solution: alkaline pectinase 1 g / L, neutral protease 0.7g / L, cellulase 0.2g / L;
[0031] The enzyme activity of the alkaline pectinase is 350 U / g, the enzyme activ...
