Typical properties and quality of essential oils

Typical properties and quality of essential oils can change from oil that is still in the oil-containing material, during the process of extraction, storage and marketing. For it should be noted ranging from raw material handling techniques to the storage of essential oils.GLOBALBOLA.COM AGEN BOLA PIALA DUNIA 2014 SBOBET IBCBET CASINO POKER Another difficulty in analyzing the oil is because most of the components is a liquid, so that the necessary fractionation techniques. Factors affecting the yield of coriander oil is affected by (1) the drying temperature, dried with a dryer should be no more than 40 º C, (2) the level of ripeness of the fruit of coriander, coriander immature fruit will produce quality and low oil yield. Mature coriander and immediately distilled, producing oil yield of approximately 0.83%. Ripening of fruit is not the same but gradually it takes for an assessment to determine the optimal harvest time. Setyaningsih research results (1992), suggests that physiology is reached when cooking coriander fruit is yellow to brown (about 4-6 months after planting) begins with an umbrella stem drying followed by a hardening of the base of the stalk attachment to the fruits and the fruits of his umbrella in the umbrella has changed color from green to golden brown, (3) the land where grown, coriander plants suited to the soil at planting rather clay, (4) climate, (5) the size of the shape of fruits coriander, cilantro small fruit yield a higher oil yield than fruits are large and (6) refining techniques, on steam distillation, the amount of water in direct contact with the material refined, cultivated as little as possible, but water must be there to help smooth the process of diffusion, (7) varieties of coriander, Coriandrum sativum var varieties. DC microcarpum fruit diameter ranged from 1.5 to 3 mm smaller volatile oil content is higher than the Coriandrum sativum var. Alet vulgare fruit diameters ranging from 3-6 mm (Ketaren, 1985; Guenther, 1987; Purseglove et al., 1981; Hadipoentyanti and Udarno, 2002). Linaool is the main constituent of coriander oil, coriander oil linalool contained approximately 60-70%, linalool terpenoid compounds including alcohols, liquid, colorless and scented. Linalool has the empirical formula CHO structural formula 3,7-dimethyl-3 10 181.6 oktadien-ol, linalool is not cyclic alcohol compound (straight) (http://chemicalland 21.com/specialty-chem/perchem/linalool. Htm ). Linalool can be made of natural and synthetic, naturally derived from the flowers of lavender, bergamot, rose wood, lemongrass, lime leaves and flowers. While the synthesis of linalool obtained from and - pinene and processed etimilasi with acetylene into dehidrolinalool catalyst, produces linalool through the process of a triple bond hydrogenasi with other carbon palladium catalysts. Compound synthesis components like linalool linalool a natural, soft fragrant scent like bergamot (http://www.Leffing-well.com/bacis/bnb 99 081. Html). 2 contains linalool antipode enantiomer or a circle that has a name (R) (-) linalool or likareol and (S) (+) linalool or koriandrol. Likareol contained in lavender while koriandrol contained in cilantro that produces fragrant aroma. Compound linalool are components that determine the intensity of the fragrance, so that coriander oil can be used as raw material of perfume, scent like lavender or bergamot oil. Linalool is widely used in the pharmaceutical industry as an analgesic drug (drugs suppress pain), perfume, the smell of food and beverages, soap, wax base material, laundry soap, synthetic vitamin E and warehouse pests and pesticides insektida to destroy cockroaches and mosquitoes. Coriander usefulness as a diuretic drugs, among other things (urine laxative), antipyretic (fever-reducing), stomatik (amplifier stomach), stimulants (stimulant), laxatif (purgatives), antelmintif (issued worms), increase appetite, treat sick bile and bronchitis (Wahab and Hasanah, 1996). Identification of linalool in the oil carried by the gas ABCBOLA.COM Agen Judi Bola Terpercaya Piala Dunia 2014  chromatography method and using an authentic standard material linalool. Analysis by gas chromatography methods provide qualitative and quantitative information about the major components in the oil. Besides, the results of gas chromatography is also a fingerprint (fingger print) that can rapidly demonstrate the quality and purity of an essential oil.
