Embodiment Construction
[0048] The present invention will be described in further detail below in conjunction with specific examples. This example is only to illustrate the present invention more clearly, rather than to limit the present invention.
[0049] 1. Preparation of fermentation agent
[0050] Inoculate the fermented strains of lactic acid bacteria (Streptococcus faecalis), Bacillus subtilis (Bscillus subiilis), Aspergillus niger (Aspergillus niger) and yeast (Saccharomyces cerevisiae) into the expanded culture medium respectively, and expand under aerobic conditions at 30-38°C. Cultivate until the number of effective bacteria is greater than 100 million / g.
[0051] The expanded culture fluid is respectively:
[0052] Lactic acid bacteria: yeast powder 10g / L, peptone 15g / L, glucose 6g / L, magnesium sulfate 0.2g / L, manganese sulfate 0.05g / L, potassium hydrogen phosphate 0.2g / L, adjust pH to 6.2-6.4, steam at 121°C Sterilize for 20 minutes, that is.
[0053] Bacillus subtilis: glucose 20g / L, p...
