Example Embodiment
[0065] Example 1
[0066] 1. Preparation of activated EM inoculants
[0067] 1A. Add brown sugar to boiled distilled water / or tap water, stir and melt, continue to boil for 15min (usually 10-20min) to achieve the purpose of sterilization, and obtain an aqueous brown sugar solution, wherein the mixture of brown sugar and distilled water / or tap water is obtained. The mass ratio is 1:8 (usually 1:(4-20), preferably 1:(6-10));
[0068] 1B. The brown sugar water is naturally cooled to a temperature lower than 40°C (usually 25-38°C, preferably 30-35°C), and then the EM bacterial agent is added, and the mixture is evenly placed in a sterilized sealed container (and the added EM bacteria The ratio of the volume of the agent-brown sugar mixed solution to the volume of the sealed container is less than 2 / 3); then activated and cultured at 30-38 ° C for 3 days to obtain an activated EM inoculum, wherein the activated EM inoculum is in The number of effective viable bacteria is ≥10 bill...

[0103] Example 2
[0104] 1. Preparation of activated EM bacterial agent
[0105] Except that the mass ratio of brown sugar to distilled water / or tap water is 1:10; the brown sugar water is naturally cooled to below 35°C at room temperature, and then the EM bacterial agent is added; the volume ratio of the added EM bacterial agent to the brown sugar water is 1:15 (usually 1:7-15); EM inoculum-brown sugar mixture is activated and cultured at 30-38°C for 5 days (usually 2-5 days) in a clean sealed container, until the number of effective viable bacteria in the activated EM inoculum is reached ≥10 billion CFU / mL, the pH value of the activated EM inoculum is 4.5, except that the activated EM inoculum is obtained, the rest are the same as in step 1) of Example 1;
[0106] 2. Preparation of fermented rice water
[0107] Except that the mass ratio of rice washing water, EM bacteria agent (or activated EM bacteria agent) and peel powder is 1:0.01:0.05; after 10 days of fermentation ...

[0114] Example 3
[0115] 1. Preparation of activated EM bacterial agent
[0116] Except that the mass ratio of brown sugar to distilled water / or tap water is 1:6; the brown sugar water is naturally cooled to below 25°C at room temperature, and then the EM bacterial agent is added; the volume ratio of the added EM bacterial agent to the brown sugar water is 1:15 ; EM bacterial agent-brown sugar mixture is activated and cultured at 30-38°C for 3 days (usually 2-5 days) in a clean sealed container, until the number of effective viable bacteria in the activated EM bacterial agent is ≥ 10 billion CFU / mL, and the EM is activated. The pH value of the inoculum is 3.5, except that the activated EM inoculum is prepared, the rest are the same as in Example 1;
[0117] 2. Preparation of fermented rice water
[0118] Except that the weight ratio of rice and water is 1:15; the mass ratio of rice washing water, EM inoculant (or activated EM inoculant prepared in step 1) and peel powder is...
