    摘要: The present application provides a synthetic spilanthol flavor composition that includes (2E,6Z,8E)-N-(2-methylpropyl)-2,6,8-decatrienamide. The synthetic spilanthol composition can also contain, and at least one of (2E,6E,8E)-N-(2-methylpropyl)-2,6,8-decatrienamide and (2E,6Z,8Z)—N-(2-methylpropyl)-2,6,8-decatrienamide, the (N-(2-methylpropyl)-2,6,8-decatrienamide being present in amounts effective to impart a salivating or tingle effect while reducing the perception of off notes, as compared to the off-notes perceived upon consumption of natural spilanthol (e.g. spilanthol obtained from jambu oleoresin). Methods of increasing salivation and/or providing a tingling sensation upon consuming an orally consumable product that include adding to the product a synthetic spilanthol flavor composition are also provided. Synthetic spilanthol flavor compositions can be added to orally consumed products, such as, but not limited to, foods, beverages, pharmaceuticals, nutraceuticals, or therapeutic compositions, oral personal care products, gums (e.g. chewing gum or bubble gum), candy or lozenges.

    摘要: Provided is a method for producing an optically active ceramide by an N-acylation (amidation) reaction of an optically active aminodiol, wherein a crude ceramide produced therein is purified by an industrially advantageous process. Namely, provided is a method for producing a high-purity ceramide that has high diastereo purity with high yield. A high-purity ceramide is produced by: a step wherein a ceramide represented by general formula (1) is produced by reacting an aminodiol with an alkyl ester having 1-5 carbon atoms of an aliphatic carboxylic acid having 12-24 carbon atoms, said aliphatic carboxylic acid optionally having a hydroxyl group, in a hydrocarbon solvent having 5-10 carbon atoms; and a step wherein an alcohol having 1-3 carbon atoms is added into the reaction mixture obtained in the preceding step, thereby causing crystals to precipitate. (In the formula, R1 represents an alkyl group which has 13-17 carbon atoms and optionally has a carbon-carbon unsaturated bond; R2 represents an alkyl group which has 11-23 carbon atoms and optionally has a hydroxyl group; and * represents an optically active state.).
