Abstract: A method for obscuring or masking the odor of p-cresol using olfactory receptor antagonism without affecting the flavor of a food or beverage is provided. The method includes the use of a specific concentration of ambrettolide, isoambrettolide, pentalide, muscone, civetone, ?-2-decenolactone, cinnamic aldehyde, (3-caryophyllene oxide, sclareolide, and ethyl maltol in a food or beverage. A citral-containing product containing one or more of ambrettolide, isoambrettolide, pentalide, muscone, civetone, ?-2-decenolactone, cinnamic aldehyde, (3-caryophyllene oxide, sclareolide, and ethyl maltol, and a flavor composition are provided.

Abstract: The present invention relates to a screening method for materials that suppress the characteristic body odor of elderly people.

Abstract: The present invention relates to a screening method for materials suppressing one or more offensive odors selected from the group consisting of a 1-octen-3-one odor, a 1,5-octadien-3-one odor, a 1-octen-3-ol odor and a 1,5-octadien-3-ol odor, an offensive odor-suppressing composition for reducing the offensiveness of age-related body odors and/or underarm odors, as well as a flavor composition for reducing off-flavors derived from food and beverage products. By using the screening method of the present invention, candidate substances for materials suppressing a 1-octen-3-one odor, a 1,5-octadien-3-one odor, a 1-octen-3-ol odor and a 1,5-octadien-3-ol odor can be selected respectively from among many test substances.

Abstract: The present invention relates to a fragrance or flavor composition comprising a fragrance or flavor component acting on at least one olfactory receptor polypeptide selected from the group consisting of (a) OR2C1 and OR4Q3, and (b) polypeptides which comprise an amino acid sequence sharing an identity of at least 80% with the amino acid sequence of any of the polypeptides in (a) and which are responsive to at least one offensive odor-causing substance selected from the group consisting of trans-2-nonenal, trans-2-octenal, 1-octen-3-one, 1,5-octadien-3-one, 1-octen-3-ol and 1,5-octadien-3-ol to suppress the response intensity of the olfactory receptor polypeptide(s) to at least one of the offensive odor-causing substances, and also relates to a product comprising this fragrance or flavor composition and a method for suppressing offensive odors.
