Isoeugenol
Isoeugenol is a propenyl-substituted guaiacol. A phenylpropanoid, it occurs in the essential oils of plants such as ylang-ylang (''Cananga odorata''), and is a component of wood smoke and liquid smoke. It can be synthesized from eugenol and has been used in the manufacture of vanillin. It may occur as either the cis ''(Z)'' or trans ''(E)'' isomer In chemistry, isomers are molecules or polyatomic ions with identical molecular formula – that is, the same number of atoms of each element (chemistry), element – but distinct arrangements of atoms in space. ''Isomerism'' refers to the exi .... Trans ''(E)'' isoeugenol is crystalline while cis ''(Z)'' isoeugenol is a liquid. Isoeugenol is one of several phenolic compounds responsible for the mold-inhibiting effect of smoke on meats and cheeses. Allergy Some individuals experience a hives-like reaction to long-term exposure to Isoeugenol, which is named as ''Fragrance'' in the ingredients of consumer products such as soaps, sham ...

Eugenol
Eugenol is an allyl chain-substituted guaiacol, a member of the allylbenzene class of chemical compounds. It is a colorless to pale yellow, aromatic oily liquid extracted from certain essential oils especially from clove, nutmeg, cinnamon, basil and bay leaf. It is present in concentrations of 80–90% in clove bud oil and at 82–88% in clove leaf oil. Eugenol has a pleasant, spicy, clove-like scent. The name is derived from ''Eugenia caryophyllata'', the former Linnean nomenclature term for cloves. The currently accepted name is ''Syzygium aromaticum''. Biosynthesis The biosynthesis of eugenol begins with the amino acid tyrosine. L-tyrosine is converted to ''p''-coumaric acid by the enzyme tyrosine ammonia lyase (TAL). From here, ''p''-coumaric acid is converted to caffeic acid by ''p''-coumarate 3-hydroxylase using oxygen and NADPH. ''S''-Adenosyl methionine (SAM) is then used to methylate caffeic acid, forming ferulic acid, which is in turn converted to feruloyl- ...

Vanillin
Vanillin is an organic compound with the molecular formula . It is a phenolic aldehyde. Its functional groups include aldehyde, hydroxyl, and ether. It is the primary component of the ethanolic extract of the vanilla bean. Synthetic vanillin is now used more often than natural vanilla extract as a flavoring in foods, beverages, and pharmaceuticals. Vanillin and ethylvanillin are used by the food industry; ethylvanillin is more expensive, but has a stronger note. It differs from vanillin by having an ethoxy group (−O−CH2CH3) instead of a methoxy group (−O−CH3). Natural vanilla extract is a mixture of several hundred different compounds in addition to vanillin. Artificial vanilla flavoring is often a solution of pure vanillin, usually of synthetic origin. Because of the scarcity and expense of natural vanilla extract, synthetic preparation of its predominant component has long been of interest. The first commercial synthesis of vanillin began with the more readily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guaiacol
Guaiacol () is an organic compound with the formula C6H4(OH)(OCH3). It is a phenolic compound containing a methoxy functional group. Guaiacol appears as a viscous colorless oil, although aged or impure samples are often yellowish. It occurs widely in nature and is a common product of the pyrolysis of wood. Occurrence Guaiacol is usually derived from guaiacum or wood creosote. There also appears to be a petrochemical route to it with great commercial use. It is produced by a variety of plants. It is also found in essential oils from celery seeds, tobacco leaves, orange leaves, and lemon peels. The pure substance is colorless, but samples become yellow upon exposure to air and light. The compound is present in wood smoke, resulting from the pyrolysis of lignin. The compound contributes to the flavor of many substances such as whiskey and roasted coffee. Preparation The compound was first isolated by Otto Unverdorben in 1826. Guaiacol is produced by methylation of ''o''-cat ...

Phenylpropanoid
The phenylpropanoids are a diverse family of organic compounds that are biosynthesized by plants from the amino acids phenylalanine and tyrosine in the shikimic acid pathway. Their name is derived from the six-carbon, aromatic phenyl group and the three-carbon propene tail of coumaric acid, which is the central intermediate in phenylpropanoid biosynthesis. From 4-Coumaroyl-CoA, 4-coumaroyl-CoA emanates the biosynthesis of myriad natural products including Monolignol, lignols (precursors to lignin and lignocellulose), flavonoids, isoflavonoids, coumarins, aurones, stilbenes, catechin, and phenylpropanoids. The coumaroyl component is produced from cinnamic acid. Phenylpropanoids are found throughout the plant kingdom, where they serve as essential components of a number of structural polymers, provide protection from ultraviolet light, defend against herbivores and pathogens, and also mediate plant-pollinator interactions as floral pigments and scent compounds.

Essential Oil
An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove. An essential oil is essential in the sense that it contains the essence of the plant's fragrance—the characteristic fragrance of the plant from which it is derived. The term "essential" used here does ''not'' mean required or usable by the human body, as with the terms essential amino acid or essential fatty acid, which are so called because they are nutritionally required by a living organism. Essential oils are generally extracted by distillation, often by using steam. Other processes include expression, solvent extraction, '' sfumatura'', absolute oil extraction, resin tapping, wax embedding, and cold pressing. They are used in perfumes, cosmetics, soaps, ...

Ylang-ylang
''Cananga odorata'', known as ylang-ylang ( ) or cananga tree, is a tropical tree that is native to the Philippines, Malaysia, Indonesia, New Guinea, the Solomon Islands, and Queensland, Australia. It is also native to parts of Thailand and Vietnam. It is valued for the essential oils extracted from its flowers (also called "ylang-ylang"), which has a strong Floral scent, floral fragrance. Ylang-ylang is one of the most extensively used natural materials in the perfume industry, earning it the name "Queen of Perfumes". The climbing ylang-ylang vine, ''Artabotrys hexapetalus'' (synonym ''A. odoratissimus'') is a woody, evergreen climbing plant in the same family, which is also a source of perfume. Etymology and nomenclature The name ''ylang-ylang'' is the Philippine Spanish, Spanish spelling of the Tagalog language, Tagalog term for the tree, - a reduplication, reduplicative form of the word , meaning "wilderness", alluding to the tree's natural habitat.

Liquid Smoke
Liquid smoke is a water-soluble yellow to red liquid used as a flavoring as a substitute for cooking with wood smoke while retaining a similar flavor. It can be used to flavor any meat or vegetable. It is available as pure condensed smoke from various types of wood, and as derivative formulas containing additives. History Pyrolysis or thermal decomposition of wood in a low oxygen manner originated prehistorically to produce charcoal. Condensates of the vapors eventually were made and found useful as preservatives. For centuries, water-based condensates of wood smoke were popularly called " wood vinegar", presumably due to its use as food vinegar. In 1658, Johann Rudolf Glauber outlined the methods to produce wood vinegar during charcoal making. Further, he described the use of the water insoluble tar fraction as a wood preservative and documented the freezing of the wood vinegar to concentrate it. Use of the term " pyroligneous acid" for wood vinegar emerged by 1788. In the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
