Introduction | stone grass oil (Vean oil) is a light yellow brown to light red brown viscous liquid with sweet grass and soil aroma. With similar sandalwood aroma, fragrant and lasting, is one of the important fragrant raw materials, widely used in cosmetics, soap flavor, can also be used as a fixed flavor agent. Natural essential oils, other well-known aromatic essential oils include: rose oil, Jasmine Extract, geranium oil, vanilla oil, patchouli oil, lavender oil, ylang ylang oil, carnan oil, sandalwood oil, perilla oil, rosemary oil, camphor leaf oil, eucalyptus oil, rose oil, etc. |

efficacy and role | the efficacy and role of the root oil: bactericidal anti-inflammatory, promote wound healing, can treat acne, promotes the regeneration and healing of body cells. It is also a well-known sedative oil, balancing the central nervous system, good sedative effect, make people refreshing, improve the pressure, Anxiety, Sleep Initiation and Maintenance Disorders and anxiety and other symptoms. |
application field | Vetiveria zizanioides essential oil is widely used as an additive for high quality spices and food composite spices, and is a kind of expensive perfume oil. The natural flavor of the food is allowed to be added by the state. Vetiveria zizanioides has been successfully widely used in the ecological environment management, but so far, there is little research on deep processing and application of food additives, and the research on extraction and chemical composition analysis of Vetiveria zizanioides is almost blank. |
extraction process | The oil was extracted from the root of cymbidium by steam distillation, the oil yield was 2% to 5%. |
Natural flavor | vetiver oil, also known as vetiver oil, is a kind of natural flavor extracted from vetiver grass, vetiveria zizanioides is native to Sri Lanka and India. Apart from being grown in Indonesia and Haiti, it is also produced in some island states in the Pacific and Caribbean, South America and West Africa. It is said that the best quality of the Veen oil is obtained from the Union, where it is called Bourbon vetiver. A brown or brown-red transparent viscous liquid with a woody aroma, with a relative density of 0.998 to 1.048, a refractive index of 1.521 to 1.531, a rotation of 15 ° to 45 °, and an acid value of less than or equal to 55, ester value> 10. Flash point 130 °c. |
plant morphology | Vetiveria zizanioides, also known as Vetiveria sinensis, is a perennial herb belonging to grass. Fibrous root type, the root of which is large, is considered to be "the longest root in the world". The fibrous roots were light yellow to yellow brown, and the old roots were deep in color, with strong sandalwood aroma, 1~1.5m long, 3~4mm thick, and spread out in the depth of the soil layer 20~25cm. The rod was vertical, coarse, clustered, 1.5~2 m in length. Leaves long and narrow, linear, upright, hard, 0.7~1.5 m long, 7 ~ wide, base extending, flat or slightly folded when dry, leaf sheath flattened with middle ridges, hairless, ligule small, margin membranous. Panicles are terminal, upright, purple or light green, many branches are in rotation, the spindle of the inflorescence is thick, the branches are thin, 5-12cm in length, the sessile spikelets are both hermaphroditic, linear-shaped, the base basin is short hair, the first glume leathery or grass, oblong, folded in the margin, the second glume leathery, the margin is transparent membrane, there are eyelashes, the first lemma is transparent, there are eyelashes, second Lemma apex dentate, indentate; Sessile spikelet male, resembling sessile spikelet. Heading stage in autumn. Vetiveria zizanioides originated in India, Sri Lanka, Malaysia and other countries. It was introduced from Indonesia to China in 1958, and is now planted in Guangdong, Zhejiang, Fujian, Taiwan and other regions. In foreign countries, India, Sri Lanka, Malaysia and other countries are wild; Mene Island, Haiti, Brazil, Indonesia, Java are widely cultivated; Honduras, Guatemala, Mexico and the United States are also cultivated. But the quality of the island of rouniwan is the best. |
Vetiveria zizanioides essential oil market application and extraction technology analysis | Vetiveria zizanioides essential oil development value is extremely high, international and domestic market demand. At present, the domestic research on Vetiveria zizanioides mainly has two main directions:(1) Vetiveria zizanioides essential oil extraction; (2) Vetiveria zizanioides ecological application. The main ingredients of vetiver oil include vetiverenol, vetiverone, terpenes (such as petrolatenes) and sesquiterpene (ENE) compounds, and its active ingredients are mainly used in the prevention or treatment of diseases, for example, it is used as a raw material for cosmetics, medicines, plant insecticides, disinfectants, insect repellents, medicinal tea, medicinal liquor, etc. Vetiveria zizanioides has been successfully widely used in the ecological environment management, but so far, there is little research on deep processing and application of food additives, and the research on extraction and chemical composition analysis of Vetiveria zizanioides is almost blank. In 2004, Ulian et al. analyzed the chemical composition of the root oil, but did not identify the chemical structure of the root oil. In 2004, Huang Jinghua et al analyzed the chemical composition of volatile matter in the root of vanilla grass. The main component of the root is valeriene, the content is 30.36%, and the remaining components are less than 10%, most of which are terpenes, alkenes and alcohols. In 1997, Gong Deshen, Wei Desheng and other conventional methods to extract the root oil, a preliminary analysis of the chemical composition of the root oil, mainly alkene, alcohol, terpene, ketone and other substances, but the structure is unknown. |
Use limit | is moderately limited (FDA,§ 172.510,2000). |
Use | GB 2760-96 specifies the permitted use of flavorants. as a food spice. |
production method | native to Malaysia, Sri Lanka, India, Indonesia: introduced to Taiwan, Guangdong, China, zhejiang and Fujian and other places of Gramineae perennial herbaceous plant vedren as raw material, by pressurized series steam distillation obtained, oil yield of about 4%. The roots of triselium sinensis were washed with water to dry, cut into 2cm long thin sections, charged into a distillation pan in an amount of 60kg/m3, and subjected to 18h of pressure-series distillation. The pressure of the direct steam distillation in the first pot is 350-400kPa, and the direct steam pressure in the second pot is 300-350kPa. The distillation rate is 2.0 to 2.5L/(min · m3) of the distillate. After cooling, the distillate is separated to obtain essential oil, and a small amount of essential oil can be recovered from the distillate by multi-stage sedimentation method. dried grass roots from Vetiveria zizanioides were extracted by steam distillation. The yield ranged from 2% to 5%. |
