Fragrances peppermint

The flavor and fragrance industry has expanded so much that the plants required to supply the raw materials are now grown on a very large scale. Examples are the peppermint and spearmint plantations in the United States, the lavandin plantations in southern France and the cornmint plantations in China and India. 

A technique known as contingent negative variation (CNV) measures brain-wave reaction to olfaction. These types of studies have shown the eftect of materials such as lavender and nutmeg in reducing stress or anxiety, and the ability of oils such as peppermint to stimulate brainwave activity. CNV research was incorporated into the development of the fragrance for a consumer personal care product launched in the late 1980s. 

Alcohols occur widely in nature. Methanol is also known as wood alcohol because it can be obtained by distilling wood in the absence of air. It is very poisonous and can cause blindness or death if ingested. Ethanol is consumed in alcoholic beverages. Other simple alcohols, such as 2-phenylethanol from roses and menthol from peppermint, are constituents of natural flavors and fragrances. Alcohols are important intermediates in chemical synthesis. They are also commonly used as solvents for various chemical processes. Ethylene glycol is used in antifreeze and in the preparation of polymers such as Dacron. 

Therea renumerous species of mint including peppermint, Mcnf/zapipenta, spearmint, Mentha spicata, and cornmint, Mentha arvensis. Mentha piperita is actually a hybrid species bred from spearmint Mentha spicata and watermint Mentha aquatica. They all contain subspecies and chemotypes. Mints have a long tradition of culinary, fragrance, cosmetic and therapeutic applications. 

Citral is an example of a very large group of natural products called terpenes. They are responsible for the characteristic odors of plants such as eucalyptus, pine, mint, peppermint, and lemon. The odors of camphor, menthol, lavender, rose, and hundreds of other fragrances are due to terpenes, which have ten carbon atoms with double bonds, and aldehyde, ketone, or alcohol functional groups.

With the advent of hydrophobic cyclodextrin derivatives, many chiral constituents of essential oils became the subject of a detailed investigation of their enantiomeric composition. Several essential oils are used as additives in pharmaceutical formulations, for example, pine needle oil or peppermint oil. They are not only used for their pleasant flavor or fragrance, monoterpene hydrocarbons like a-pinene 18], p-pinene [9], and... 

Pure peppermint essential oil In research, peppermint oil has been shown to provide a quick boost of energy when inhaled. Put a few drops of the oil on a handkerchief and inhale, or add a few drops to an aromatherapy diffuser and breathe deeply. Make sure you re using pure peppermint essential oil and not "fragrance" oil, which is synthetic and usually contains toxic ingredients. 

Derivation (1) Lemon, bergamot, caraway, orange, and other oils, (2) peppermint and spearmint oils. Use Flavoring, fragrance and perfume materials, solvent, wetting agent, resin manufacture. 

Extraction of Essential Oils from Plants. Essential oils are aromatic substances widely used in the perfume industry, the pharmaceutical sector, and the food and human nutrition field. They are mixtures of more than 200 compounds that can be grouped basically into two fractions a volatile fraction, which constitutes 90-95% of the whole oil, and a nonvolatile residue, which constitutes the remaining 5-10%. The isolation, concentration, and purification of essential oils have been important processes for many years, as a consequence of the widespread use of these compounds. The common methods used are mainly based on solvent extraction and steam distillation. SFE has been used for the extraction of essential oils from plants, in an attempt to avoid the drawbacks linked to conventional techniques (57). Such is the case with the extraction of flavor and fragrance compounds, such as those from rose (58), rosemary (59), peppermint (60), eucalyptus (61), and guajava (62). The on-line coupling of the extraction and separation ietermi-nation steps (by SFE-GC-FID) has been proposed successfully for the analysis of herbs (63) and for vetiver essential oil (64).

Procedure Mix surfactant and fragrance oil with enough heat to make a clear solution. Add water slowly with stirring. This procedure can also be used to solubilize the flavor oils methyl salicylate, peppermint oil, or spearmint oil in water (5, 7, 5 g, respectively, of polysorbate-80 per gram of oil) for mouthwash. 

Menthan-3-ol forms four pairs of enantiomers. The levorotatory (1J ,3R,45)-enantiomer referred to as (-)-menthol represents the most significant. It is the major component of peppermint oil obtained from the fresh-flowering plant Mentha piperita (Labiatae), and is widely used for flavoring and as fragrance in confectionery and perfumery.
