It is the national flower of the PhilippinesPowerPoint Presentation: Technical data sheet Jasmine Concrete English name Jasminum officinale Scientific name June – October Harvest time Fresh flowers Used part of plant Extraction of fresh flowers by hexane Producing method 2-3kgs./ton YieldJASMINE EXTRACTION: JASMINE EXTRACTION Jasmine concrete and absolute are the valuable perfumery products used in expensive floral perfumes. Jasmine oil and its synthetic substitutes are extensively used in high grade perfumes. The main buyers being U.S.A,U.K,France,Japan,Holland and Russia.PowerPoint Presentation: CONCRETE: It is a wax like substance containing the natural flower perfume as a volatile oil,together with some plant waxes and albuminous and colouring matter.250-350 gram of concrete is obtained from 100kg of flowers.PowerPoint Presentation: ABSOLUTE: Is a yellowish brown viscous oily substance having the delicate odour of fresh jasmine flowers. The yield of absolute from the concrete varies from 40-60% depending on the quality of the concrete.Traditional methods of extracting essences: Traditional methods of extracting essences Not usually water soluble Macerate (chop) plant parts in hot oil, then extract with alcohol Enfleurage F lowers placed on layer of purified fat or oil T hey are replaced every couple of weeks Y ields outstanding scents, very expensivePowerPoint Presentation: Attars (steam distillates) being prepared in IndiaMETHODS OF EXTRACTION: METHODS OF EXTRACTIONPowerPoint Presentation: Using organic solvents Enfleurage process Steam distillation Other methodsUsing organic solvents: Using organic solvents Equipments involved in this method arePowerPoint Presentation: 1.Extractor 2.Evaporator 3.Condensation 4.DistillationPowerPoint Presentation: Solvents used:PowerPoint Presentation: 1.Food grade Hexane(FGH) 2.Perfumery grade hexane(PGH) 3.Carbontetra chloride(CTC) 4.Petroleum etherPowerPoint Presentation: 1.EXTRACTOR: Harvest the flowers before 9.30 a.m Add 2lit of hexane/kg of flower Soak for 30min Rotation with handle for 20minutes The perfume substances are dissolved in the hexanePowerPoint Presentation: 2.EVAPORATION: Perfume laden solvent is fed into the evaporator Leave it to evaporate at 75*cPowerPoint Presentation: 3.CONDENSATION: The vapour of the solvent is condensed into the liquid The liquid containing the perfume, wax and other pigmentsPowerPoint Presentation: 4.DISTILLATION: The liquid containing the perfume, wax and other pigments is distilled in a vaccum distillation unit for complete removal of solvent.PowerPoint Presentation: CONCRETE YIELD: Jasminum.grandiflorum - 0.25-0.32% Jasminum.sambac - 0.14-0.19% Jasminum.auriculatum - 0.28-0.36% MARKET VALUE: Price of concrete ranges from 30 to 60,000/kgENFLEURAGE METHOD: ENFLEURAGE METHOD In this method animal fats are used for extraction Freshly prepared flowers are placed on layers of fat and the trays are stacked one over the other Leave it for few days and continue the procedure for several weeks until the fat layers are saturated with perfume oil Collect all the fatty layers and then melt it which is then extracted with alcohol.ENFLEURAGE METHOD: ENFLEURAGE METHODPowerPoint Presentation: DISADVANTAGES: Expensive method Time consuming Labouries STEAM DISTILLATION: : STEAM DISTILLATION: In this method, most of the voltile components of the flower evaporate under high temperature involved. Hence, this method is not adopted. STEAM DISTILLATION UNIT : STEAM DISTILLATION UNITPowerPoint Presentation: 4.OTHER METHODS: 1.Super critical extraction method: Recently developed technique using liquid co2 and extraction with hydro flurocarbon -134 a solvent which yield high quality concrete.PowerPoint Presentation: 2.Dynamic adsorption process Perfume of the flowers is voltilized and the vapours are absorbed onto a purified activated charcoal. This method is not employed in India SPECIFICATIONS : SPECIFICATIONS Storage condition: In a dark, cool (Not more than 5ºC), dry and ventilated area Shelf life: 36 months in proper storage. Sensory properties: Appearance : Dark Yellow to Pale Brown Soft Greasy Bulk at20ºC . Odour : Beautiful odor characteristic of live Jasmine flowers. Chemical-physical properties : Chemical-physical properties Impurities : none. Water Content : nil. Hexane Content : traces. Water Solubility : insoluble. Absolute Content : Not Less Than 50% Alcohol Insoluble Mater : Not More Than 50% Melting Point : 47ºC - 55ºC Density 60/20 : 0.8860 - 0.8987 Acid Value : not more than 20 Ester No 68 - 110PowerPoint Presentation: Precautions Jasmine oil is non-toxic, non-irritant and generally non-sensitizing, although some people do have an allergic reaction to the oil. Due to its emmenagogue properties it should not be used in pregnancy. Using too much of this oil could impede concentration, as it is a deeply relaxing oil.PowerPoint Presentation: Therapeutic properties The therapeutic properties of jasmine oil are anti-depressant, antiseptic, aphrodisiac, anti-spasmodic, cicatrisant , expectorant, galactagogue , parturient, sedative and uterine.PowerPoint Presentation: Uses It is a valuable remedy in cases of severe depression and soothes the nerves, producing a feeling of confidence, optimism and euphoria, while revitalizing and restoring energy.PowerPoint Presentation: It has a very beneficial effect on the respiratory system, by soothing irritating coughs and helping with hoarseness and laryngitis. It furthermore helps with muscle pain, sprains, and stiff limbs.PowerPoint Presentation: Jasmine oil blends well with Although essential oils blend well with most other oils, Jasmine oil blends particularly well with Bergamot , Rose , Sandalwood and all Citrus oils.PowerPoint Presentation: Burners and vaporizers In vapor therapy, jasmine oil can be useful for treating addiction, lifting depression, easing nervousness, soothing coughs, promoting relaxation and easing tension. Blended massage oil or in the bath Jasmine oil can be used as a blended massage oil or diluted in the bath, for helping to break addiction, lifting postnatal depression, promoting relaxation, easing muscle pain, soothing coughs, reducing tension, stress and nervousness. Lotion and creams Jasmine oil can be used in a cream or lotion for dry, greasy or sensitive skin, as well as to help reduce stretch marks and other scars.PowerPoint Presentation: THANK YOU You do not have the permission to view this presentation.
