  Improved aromachemical derivatives, and fragrances and flavorings including the derivatives, that have a longer useful shelf life than the aromachemicals from which they can be derived, are disclosed. In particular, the derivatives maintain the fragrance characteristics of the aromachemicals, while lowering the allergic properties, increasing the stability, and/or increasing the odor intensity. Also disclosed are methods of making the derivatives, and articles of manufacture including the derivatives. In one embodiment, the derivatives are prepared by replacing one or more double bonds in citral with a thioether, cyclopropyl, oxirane, or thiirane group. The cyclopropane ring can be unsubstituted, or substituted with one or two lower alkyl, preferably methyl groups. The alkyl groups can optionally be substituted, for example, with electron donating groups, electron with drawing groups, groups which increase the hydrophilicity or hydrophobocity, and the like. In another embodiment, the derivatives are prepared by replacing the aldehyde group in the essential oil with a nitrile, methyl ether or acetal group. The acetal groups can provide the compounds with a long lasting flavor or fragrance, where the acetals slowly hydrolyze to provide the aldehyde group in the parent essential oil. In some embodiments, both the aldehyde and at least one of the double bond functional groups are both derivatized as described herein. Examples of suitable articles of manufacture include candles, air fresheners, perfumes, disinfectant compositions, hypochlorite (bleach) compositions, beverages such as beer and soda, denture cleanser tablets and flavored orally-delivered products such as lozenges, candies, and the like.

  本发明公开了改良的芳香化学衍生物，以及包含这些衍生物的香料和调味料，它们的有效货架寿命比它们可以衍生的芳香化学品更长。特别是，这些衍生物保持了芳香化学品的香气特性，同时降低了过敏性，增加了稳定性和/或增加了气味强度。本发明还公开了制备这些衍生物的方法以及包括这些衍生物的制品。在一个实施例中，这些衍生物是通过用硫醚、环丙基、环氧烷或硫代环氧烷基取代柠檬醛中的一个或多个双键来制备的。环丙烷环可以是未取代的，或者用一个或两个较低的烷基，优选是甲基基取代。烷基可以选择性地被取代，例如，用电子给予基团，电子吸引基团，增加亲水性或疏水性的基团等。在另一个实施例中，这些衍生物是通过用腈、甲醚或缩醛基取代精油中的醛基来制备的。缩醛基可以为化合物提供持久的风味或香气，其中缩醛缓慢水解以提供母体精油中的醛基。在一些实施例中，醛基和至少一个双键官能团都是根据本文所述进行衍生的。适当的制品包括蜡烛、空气清新剂、香水、消毒剂组合物、次氯酸盐（漂白剂）组合物、啤酒和苏打水等饮料、假牙清洁剂片和口味制品，例如含片、糖果等。

  It is intended to provide a novel deodorant composition which is excellent in the deodorizing effect, is capable of affording a deodorant composition by a convenient method, and shows no decrease in the deodorizing performance even after a long period of time, once the deodorant being prepared. Specifically, there is provided a deodorant composition containing, as the active component, a colored compound obtainable by reacting a polyphenol in a solvent showing alkalinity in the coexistence of an oxygen molecule at a reaction pH value of 6.5 or more. As a substitute for a polyphenol, use can be made of a plant extract containing a polyphenol but containing substantially no amino acid. It is also possible to further employ an amino acid. Furthermore, use can be made of a plant extract and/or a plant body containing a polyphenol and an amino acid.

  本发明旨在提供一种新型除臭剂组合物，该除臭剂组合物除臭效果极佳，能够通过简便的方法获得除臭剂组合物，并且在制备除臭剂后，即使经过很长时间，除臭效果也不会降低。具体来说，本发明提供了一种除臭剂组合物，该组合物含有一种有色化合物作为活性成分，该有色化合物可通过在反应 pH 值为 6.5 或更高时，使多酚在与氧分子共存的显碱性溶剂中发生反应而获得。作为多酚的替代品，可以使用含有多酚但基本上不含氨基酸的植物提取物。也可以进一步使用氨基酸。此外，还可以使用含有多酚和氨基酸的植物提取物和/或植物体。
