Manufacturing：Baeyer
isolated and did the structure identification for the pure
Terpinolene; and the Terpinolene can be manufactured from pinene being processed by sulfuric
acid ethanol solvent.
Natural existence：
According to report, small amounts of the Terpinolene exist in a few
kinds of essential oils, e.g., Manila elemi, a few kinds of pines
and firs, and Nectandra elaiophora, Dacrydium colensoi, etc..

64ppm
Confection: 0.12 ~ 48 ppm
Roasted food: 49 ppm
Supervision：FDA

Regulation：
Terpinolene is recognized by
FEMA（1965）
as GRAS，and
is approved by FDA to be edible（21，CFR
121.1164）.
The Council of Europe (1974)
enlisted the terpinolene into the Synthetic Aroma Substance
Inventory that can be temporarily added into the food and that does
