The deodorizing agent is manufactured by extracting ginger as an effective component with methanol or ethanol and water at 20-95 deg.C for 4-24 hr , For an example, 100g of ginger with a size of a 1-2 mm, 500g of methanol(99.9%) and 500g of purified water are distilled at 20-95 deg.C for 4-24 hr, cooled at 30 deg.C, extracted, and filtered with a sieve of 400 mesh. 950g of Filtrate is condensed under vacuum at 40 deg.C to give a 200g of concentrated solution of ginger. The ginger extract is used as a liquid type, a spray type, a powder type, a tablet type, and granule type. The effective concentration of the deodorizing agent is 0.25-5 wt.% as a liquid.
