Physical and Chemical Properties | Light yellow to light brown liquid, sweet lemon and herb aroma. Miscible in benzyl benzoate, diethyl phthalate, vegetable oil and propylene glycol, insoluble in glycerol and water, the East Indian type is easily dissolved in ethanol, but the West Indian type can produce turbidity. Partial destruction can occur under alkaline conditions, and inorganic acids can be polymerized and stabilized against weak organic acids. |
Use | Used as a flavoring agent, aroma flavoring agent |

content analysis | a sample of 50.0 was mixed with mg of tartaric acid 1. After shaking for 5min, filtration was performed. The filtered oil was dried over anhydrous sodium sulfate, taken up in 10.0ml and transferred into a ml graduated fine-necked flask. The remaining oil sample was stored for use in the steam distillate oil test described below. 75ml of 30% sodium bisulfite solution was added, the cap was plugged tightly and shaken until sodium bisulfite produced an adduct as a semi-solid to solid. The flask was allowed to stand at room temperature for 5min, the stopper was relaxed, and the flask was immersed in a water bath and heated to 85-90 °c. The water bath temperature was maintained with occasional shaking of the flask until the adduct was dissolved, followed by continuous heating and intermittent shaking for 30min. When the two liquid layers are completely stratified, add enough sodium bisulfite solution to make the oil layer level rise to the scale of the bottleneck. The volume percentage of citral was then determined by the following equation: X = 100-(v× 10) where V-volume number of oil layer in the fine neck flask, ml. |

Use | China GB 2760-96 for the permitted use of edible spices. Widely used in a variety of food. |
production method | from the herb citronella (Cymbopogon citronatus; Adapted name: West India) grown in tropical and subtropical regions or serpentine citronella (C. flexuosus; Adapted to name East Indian lemon grass) fresh or micro-dried whole plant, obtained by cutting and steam distillation. The yield was 0.2%-0.8%. The East Indian type is mainly produced in India, and the yield is small. The West Indian type is produced in Haiti, Honduras, Costa Rica, Brazil, etc. China's Guangdong, Fujian, Guangxi, Yunnan, Sichuan, Zhejiang, Taiwan and other places also produced. |
