Origin fermentation method and origin fermentation product prepared by same

The invention relates to the field of biological fermentation and in particular relates to an origin fermentation method and an origin fermentation product prepared by the same. The origin fermentation method comprises the following steps: acquiring fresh leaves, pulping and crushing to obtain a leaf slurry; placing the leaf slurry into a fermentation tank, adding sterilized ammonium sulphate, ammonium dihydrogen phosphate, ammonium hydrogen carbonate and an aqueous solution of corn steep liquor dry powder into a fermentation tank so as to be fermented; carrying out cell breakage, ultrafiltration, low-temperature drying and concentrating on a fermentation product, and packaging, so that the origin fermentation product is obtained. The origin fermentation method provided by the invention has the advantages that fresh leaves are crushed, bacteria and enzymes carried by the leaves are directly utilized for carrying out fermentation, no organic solvent, saccharifying enzyme or yeast is added in a fermentation process, the fermentation time is short, main ingredients of the obtained origin fermentation product are active substances beneficial to skin, such as micromolecule plant proteins, plant growth factors, plant activity auxin and part of cell growth factors, and the quality of the obtained origin fermentation product is high.
