INDEX SUBSTANCE FOR DETERMINING STALE FLAVOR OF CONSUMER GOODS

To provide an index substance for determining a stale flavor of consumer goods containing vitamin C.SOLUTION: There is provided an index substance for determining a stale flavor of consumer goods containing vitamin C, wherein the index substance for determining a stale flavor of the consumer goods comprises 1,3-di(furan-2-yl)propan-1-one. There is also provided a pseudo-stale flavor composition of vitamin C comprising 1,3-di(furan-2-yl)propan-1-one, and in the pseudo-stale flavor composition of vitamin C, the pseudo-stale flavor composition of vitamin C further comprises 4-hydroxy-2,5-dimethyl-3(2H)-furanone. There is also provided a method for determining a stale flavor of the consumer goods containing vitamin C, wherein the method for determining a stale flavor of the consumer goods uses a substance containing a 1,3-di(furan-2-yl)propan-1-one as an indicator. There is also provided a method for evaluating a stale flavor of the consumer goods containing vitamin C, wherein the method for evaluating a stale flavor comprises (a) quantifying 1,3-di(furan-2-yl)propan-1-one in a consumer goods.SELECTED DRAWING: None 【課題】ビタミンＣを含有する消費財の劣化臭判定用指標物質を提供する。【解決手段】ビタミンＣを含有する消費財の劣化臭判定用指標物質であって、１，３－ジ（フラン－２－イル）プロパン－１－オンを含む、消費財の劣化臭判定用指標物質。１，３－ジ（フラン－２－イル）プロパン－１－オンを含む、ビタミンＣの疑似劣化臭組成物、当該ビタミンＣの疑似劣化臭組成物において、４－ヒドロキシ－２，５－ジメチル－３（２Ｈ）－フラノンをさらに含む、ビタミンＣの疑似劣化臭組成物。ビタミンＣを含有する消費財の劣化臭判定方法であって、１，３－ジ（フラン－２－イル）プロパン－１－オンを含む物質を指標とする、消費財の劣化臭判定方法。ビタミンＣを含有する消費財の劣化臭評価方法であって、（ａ）消費財中の１，３－ジ（フラン－２－イル）プロパン－１－オンを定量する工程、を含む、消費財の劣化臭評価方法。【選択図】なし
