PURPOSE: To obtain ASAZUKE UME keeping the color of fresh UME and taste using microorganism-removing solution and microbicidal solution which are harmless to human bodies by preparing specific microorganism-removing solution and microbicidal solution, removing microorganisms from the fruits and the pickling tools and pickling them as adding the microbicidal solution.

CONSTITUTION: (A) (i) 8W12wt.% of sucrose fatty acid ester, (ii)18W22wt.% of ethanol and (iii)68W72wt.% of water are mixed and the solution is diluted with water 180W200-fold to prepare the microorganism-removing solution. Raw plum fruits and pickling tools are dipped in the solution for 3W6 hours, rinsed with water and drained. On the other hand, (C) (i) 45W55wt.% of ethanol, (ii)45W55wt.% of sodium hypochlorite are mixed and diluted with water 180W200-fold to prepare a microbicidal solution. Then, the barrel is filled with the plums B in stacked layers, as (D) 3W5wt.%, based on the component B, of salt and 3W6wt.% of component C are sprayed, to prepare the ASAZUKE UME.
