A method for producing an organic acid, the method comprising:

• inoculating a raw material with a Lactobacillus paracasei and fermenting said raw material and said Lactobacillus paracasei to produce said organic acid, wherein said fermenting is at a temperature of 20-35° C., a rotation speed of 60-150 r/min, and a fermentation period of 7-30 days;
• wherein said Lactobacillus paracasei has a deposit number of CGMCC No. 14813, wherein said organic acid produced by said Lactobacillus paracasei with the deposit number of CGMCC No. 14813 has an increased total content of an organic acid, as compared to an organic acid produced by an Lactobacillus paracasei strain ATCC 25302, and wherein said organic acid comprises at least three of lactic acid, acetic acid, propionic acid, butyric acid, malic acid, tartaric acid, oxalic acid, and citric acid.
