is a plant essential oil extracted from the ripe fruit of the Magnoliaceae plant star anise (commonly known as anise). Below 20 ℃, it is colorless to light yellow oily liquid with special aroma of fennel. When the temperature drops, there will be Flake crystal precipitation, and the freezing point is about 15 ℃. The relative density is 0.979~0.987, the refractive index is 1. 5525~1.5600, and the specific rotation is -2. ~ 2.. Slightly soluble in water, soluble in ethanol, ethyl ether, ethyl acetate, chloroform and other organic solvents.
It is mainly extracted from the mature dried fruit of star anise, and the yield can reach 8%~ 12%. If extracted from fresh fruit, the yield is generally 2%~ 3%.
The content of anethole in star anise oil is over 80%, and the highest content is 95%. It is the most basic raw material for extracting anethole. In addition, star anise oil as a natural flavor can be directly applied to the food industry and daily chemical industry.

Use | spices. The whole grain is used for cooking, seasoning, soup; Powder is used for meat products. Also for the extraction of essential oils. spices. It is mainly used directly for cooking and flavoring, and is also an important raw material for the preparation of spiced powder, or for the extraction of essential oils. It is mainly used for the preparation of anethole, and also used for the preparation of flavoring agents for beverages, foods, tobacco, etc., as well as in the field of medicine GB 2760-96 in China provides edible spices that are allowed to be used. It is mainly used in baked food, candy, wine, carbonated drinks and tobacco, etc. It is also the raw material of edible anethole and anisaldehyde. as a food spice. Can be used for baking food, candy, carbonated drinks, alcohol, toothpaste and tobacco. The dosage was 230mg/kg in baked food, 190mg/kg in candy, 98mg/kg in cold beverage, 50mg/kg in alcoholic beverage, 20~55mg/kg in meat; 12mg/kg in beverage; 8.0mg/kg in syrup. In fact, the most important use is to separate anethole from it and further process it into anisaldehyde and anisol. |
production method | The Magnoliaceae plant octaginatkind fruit mainly produced in Guangdong, Guangxi, Guizhou, Yunnan and other places in China is used as raw material, often pressure direct water vapor distillation obtained, fresh fruit to oil rate of about 2%~ 3%, dry fruit is 8%~ 12%. The amount of 160~180kg/m3 is charged into the distillation pan, and the distillation is carried out directly at atmospheric pressure for 5h, and the distillate is controlled to 1l/(min · m3) in the first ~ 4H, the 5th h distillate amount was 1.2L/(min · m3). Distillate by cooling, clarification, oil-water separation, vacuum dehydration of star anise oil product, the outflow of water re-steaming, also can recover a small amount of essential oil. obtained from fresh branches and leaves or mature fruits of the Magnoliaceae plant Illicium verum by steam distillation after crushing. Yield 8.5% ~ 9%(dry) or 1.8% ~ 5%(fresh). Mainly produced in China's Guangxi, Guangdong, Yunnan, Guizhou and Vietnam. |
