content analysis	determined by total alcohol content determination method (OT-5). The sample amount taken is 1.2g. The equivalent factor (e) in the calculation is 78.14.
toxicity	GRAS(FEMA). LD50 4000mg/kg (mouse, subcutaneous).
usage limit	FEMA(mg/kg): soft drink 2.0; Cold drink 2.1; Candy 7.5; Baked food 8.1; Pudding 2.9; Gum candy 31; Jelly 0.92. Moderates are limited (FDA § 172.515,2000).
use	GB 2760-1996 stipulates that those who are separated from geranium oil are allowed to use edible spices. Mainly used to prepare strawberries, ginger, preserves, grapes, grapefruit, chocolate and tobacco and other flavors.
production method	mostly obtained from geranium oil fractionation alone (geranium oil alone is limited in China). It contains geraniol and a small amount of citronellol. It can be further made into vanilla phosphate by the phosphorus trichloride method to separate geraniol and other terpene alcohols. Or heat treatment with formic acid to decompose geraniol, while citronellol produces citronella formate, which is then saponified to obtain pure product.
