摘要:
A method of dewaxing a citrus oil by subjecting the oil to a filtration process, in which the oil is caused to flow parallel to a porous membrane during which process it is maintained at a temperature of less than about 11° C., said membrane having an average pore size of from about 0.05-5 micrometres. The method produces citrus oils that are dewaxed to an unusually high extent.
摘要:
A tobacco odor deodorizing perfume composition contains a mandarin orange essential oil or a mandarin orange essential oil fraction having its terpene hydrocarbons substantially removed therefrom.
摘要:
Citrus washed oil flavors can be formulated by a process which includes treating a citrus oil with a mixture of propylene glycol and an alkanol from C1 to C4. The resulting washed oil flavors can be used as flavoring ingredients, notably for clear beverages.
摘要:
A method for the preparation of a first-pass effective citrus derived substance. First, the concentration of volatile components is reduced. Then, the material is extracted with a 60/40 to 40/60 vol/vol mixture of alcohol and water.
摘要:
A flavor extract is prepared by extraction of coca leaves to form a raw extract and treatment of the raw extract with an ion exchange resin to remove cocaine and ecgonine. The resulting flavor extract has excellent organolyptic properties.
摘要:
A reformed vetiverol comprising 40% by weight or more of khusimol and 10% by weight or less of isovalencenol is disclosed. The vetiverol, containing a small amount of isovalencenol and a large amount of khusimol imparts a milder and more elegant odor than conventional vetiver oils or vetiverols. The reformed vetiverol can be prepared by a process comprising: esterifying alcohol components in a vetiver oil or a vetiverol, heating the esterified vetiver oil or a vetiverol to thermally decompose isovalencenol esters, hydrolyzing the remaining esters into alcohols, and separating the formed alcohols.
摘要:
Crystal-clear peppermint oil maintaining its noble character and having a reduced pulegone content, enhanced menthone and menthol content, and improved stability against menthofuran oxidation breakdown is produced by a stereospecific method of reduction by hydrogenation of pulegone in situ using a saturated aqueous solution of sodium sulfite in the presence of glacial acetic acid at approximately neutral pH.
摘要:
Hypo-allergenic moss oil from which ethyl hematommate and/or ethyl chlorohematommate or atranorin and/or chloroatranorin are substantially removed. This hypo-allergenic moss oil can be produced by chromatography separation, solvent extraction, countercurrent partition, and/or membrane separation or catalytic hydrogenation treatment and/or alkaline treatment.
摘要:
A peppermint oil flavored chewing gum or confectionery composition, having incorporated therein between about 0.01% and about 5.0% by weight of the final composition of a stabilized peppermint oil having a reduced menthofuran content of from about 0.8% to about 2.0% by weight based on the weight of peppermint oil.
摘要:
Peppermint oil containing a reduced menthofuran content is prepared by reacting the peppermint oil with about 0.5% to about 15% by weight maleic anhydride, based on the weight of peppermint oil to selectively form a menthofuran-maleic anhydride adduct without otherwise affecting the flavoring agent properties of the remaining peppermint oil constituents and recovering the peppermint oil therefrom.
