The invention discloses a fermented condiment vegetable liquid, a fermented condiment vegetable 
powder and a preparation method and application of the fermented liquid and the fermented 
powder. The preparation method of the fermented condiment vegetables liquid comprises the following steps: activating 
yeast, adding the 
yeast to condiment vegetables, adjusting 
sugar degree, and conducting 
fermentation for 3-4 weeks so as to obtain the condiment vegetable 
fermentation liquor, wherein the 
yeast is comprised of 
pichia guilliermondii, 
Wickerhamomyces anomalus and brewer's yeast; and sterilizing part of the 
fermentation liquor, inoculating the fermentation liquor with 
lactobacillus and 
acetic acid bacteria, conducting sealing culturing, pouring the cultured liquid into the rest condiment vegetable fermentation liquor which is free from sterilization, conducting sealing fermentation, wherein the supernatant of the obtained fermentation liquor is the fermented condiment vegetable liquid, andthe precipitate of the fermentation liquor is 
fiber residues. The fermented condiment vegetable liquid and the 
fiber residues are subjected to 
spray drying so as to obtain the fermented condiment vegetable 
powder. The method adopts a mixed fermentation method by using non-brewer's yeast and the brewer's yeast, and the non-brewer's yeast can improve the 
flavor of the fermented liquid, and endow thefermented liquid with rich typicality and 
aroma; and simultaneously, the brewer's yeast is added to ensure that sufficient 
ethanol appears to be decomposed by the 
acetic acid bacteria and the 
lactobacillus.
