The present invention relates to a method for testing oral malodor, in particular oral malodor from onion and garlic. Described herein are methods for testing the efficacy of an oral care composition to reduce oral malodor, the method comprising the steps of: a) cleaning at least a part of the oral cavity with an oral care composition b) testing a first sample of exhaled breath from the cleaned oral cavity to provide a first test result representing a first amount of at least one oral malodor component detected in the exhaled breath c) exposing the oral cavity to an oral malodor material including or capable of forming the at least one oral malodor component and d) testing a second sample of exhaled breath from the oral cavity to provide a second test result representing a second amount of the at least one oral malodor component detected in the exhaled breath.本發明係關於用於測試口臭,特別來自於洋蔥與大蒜之口臭的方法。本文中所說明者為用於測試口腔保健組成物於減少口臭之功效的方法,該方法包含如下之步驟:a)用口腔保健組成物清潔口腔之至少一部分;b)測試來自於經清潔口腔呼出氣味之第一個樣品,以提供第一個試驗結果,其代表於該呼出氣味中所檢測之至少一種口臭組份的第一個量;c)將口腔暴露於包括或能夠形成至少一種口臭組份之口臭物質;且d)測試來自於該口腔呼出氣味之第二個樣品,以提供第二個試驗結果,其代表於該呼出氣味中所檢測之至少一種口臭組份的第二個量。
