[Abstract] In this examination, antioxidant activities and whitening effects of yuzu(Citrus junos Sieb.ex Tanaka ) and lime(Citrus aurantifolia S.) essencial oils which are widely used in food flavors were studied. As a result, we found out that 1% to 2% concentration yuzu essencial oil contains equal antioxidant activity to □-tocopherol which is a substance commercially used as antioxidant. Also, from the result of tyrosinase activity inhibition test, an evaluation test on whitening effects, we found out that 1% to 2% concentration lime essencial oil contains higher inhibiting activation than arbutin which is a substance highly used in commercial cosmetics.
