ESSENTIAL OILS -SPICE OILS-CARRIER OILS
Supply,details and cultivation
The essential oils are derived from plant origins and are steam distilled from the parts of the plant, root or flower.
Essential oils are the volatile, powerfully concentrated essences of plants. They are found in a variety of plant parts, including roots (as in vetiver), leaves (as in patchouli), flowers (as in lotus), citrus fruits (as in lemon) and seeds (as in fennel).Essential oils contain hundreds of organic constituents, including hormones, vitamins and other natural elements that work on many levels. They are 75 to 100 times more concentrated than the oils in dried herbs.

Base oils, Carrier Oils, Spice oils
The Base oils or carrier oils are those which are mostly vegetable based oils that are used in various blends in aromatherapy.
Different carrier oils offer different properties and the choice of carrier oil can depend on the therapeutic benefit being sought.
Carrier oils are cold-pressed vegetable oils derived from the fatty portions of the plant. Unlike essential oils that evaporate and have a concentrated aroma, carrier oils do not evaporate or impart their aroma as strongly as essential oils.
Bergamot Oil, Lemon Oil, Neroli Oil, Chamomile oil (Blue), Carrot Seed Oil, Apricot Kernel Oil, Avacado Oil, Jojoba Oil, Grapeseed Oil, Peanut Oil, Wheatgerm Oil, Evening primrose Oil, Macadamia Oil, Walnut Oil, Sesame Seed Oil, Sunflower Non refined oil, Castor Oil, Canola Oil, Borage Oil , Pure Virgin Coconut oil.
Examples of carrier oils are sweet almond, apricot kernel, grapeseed, avocado, peanut, olive, pecan, macadamia nut, sesame, evening primrose, walnut and wheat germ. Most oils bought in the grocery store are not cold-pressed. Instead, the oils are heated and therefore have less therapeutic benefit. Mineral oil is not used in aromatherapy because mineral oil is not a natural product. It is also said that mineral oil can prevent essential oil absorption into the skin.
Most of our carrier oils are designed for blending and comes with vitamin E added to prevent it from going rancid. They are custom cold pressed and natural.
On steam Distillation the spices yield their volatile consttuents. The essential oils thus obtained are endowed with the major part of the spice flavour and fragrance properties.
The spice oils although charecterised on the basis of their physico chemical properties, including GLC and spectrophotometric charecteristics, are ultimately judged by sensory and oleofactory evaluation.
The Oleoresins, containing all the volatile as well as nonvolatile constituents of the spices, most closely resemble the total flavour of the fresh spice in a highly concentarted form.The oleoresins are manufactured by the extraction of the dry spices with an organic solvent or solvent mixture.
Spice oils and oleoresins can be used to advantage wherever spices are used, except in those applications where the appearance or the filleraspect of the spice is of importance.

OIL PRODUCTION METHODS-TYPES
Essential oils -Natural Plant and botanical derivatives from Plant Leaves, bark, roots ,fruits and flowers or seeds.
Spice oils are basically extracts from the spice seeds or spice plant parts... and they are 100 percent pure extracts that retain the full body and flavor profile of the particular spice.
Essential Oils Production:
Different processing methods are required to extract essential oils from different plants.
Cold Press extract:
This method uses pressure to physically squeeze the oil from the plant tissue. This method is practical for fruits and seeds because of the unique oil bearing structure of the fruits and seeds.
Steam Distillation :
A large selection of oils are extracted using steam distillation, during which the plant material is processed with steam. As the plant tissues break down, the essential oils and water vapor are released, which are condensed and cooled. The volatile essential oil condenses, separates and is isolated through the seperators.
Several Methods are used to purify the oil mixture to get to the 99and above purity percentages.
Solvent extraction is used when the odorous properties of delicate flower and plant material would be altered or destroyed by steam or water distillation or when a plant, for instance rose absolute and jasmine contains very little oil, making steam or water distillation impractical. Solvent extraction produces a concrete which in turn is refined into an absolute.
To produce a concrete, the plant material is gradually saturated with a hydrocarbon solvent. The solvent dissolves the plants constituents including essential oils, fatty acids and waxes. After the solvent is distilled off the remaining constituents make up the concrete. The essential oil is extracted from the other constituents with alcohol. The fatty acids and waxes are not alcohol soluble so they're left behind. A secondary distillation then removes the alcohol, leaving the absolute oil behind.
Among the latest entry into the segment of extraction to provide absolute pure botanical oils is the carbon di oxide extraction process. In this process CO-2 in liquified form is passed through the plant tissue under pressure and the extracted product is allowed to pass through fractionating columns where CO-2 is removed to produce an absolute pure extract.
