Volatile and semi-volatile components of jetsam ambergris

Natural Product Research, 2019
Volatile and semi-volatile compounds account for the odors, long valued in the perfumery industry, of the natural product, ambergris. Here we demonstrate application of solid phase micro extraction (SPME) and gas chromatography-mass spectrometry (GC-MS) to headspace analysis of the volatiles and semi-volatiles of jetsam ambergris. The samples collected

Volatile components of the frying process

Grasas y Aceites, 1998
In the course of deep fat frying, food contacts oil at about 180 °C and is partially exposed to air for various periods of time. Thus frying, more than any other standard food process or handling method, has the greatest potential for causing chemical ...

On the Consequences of the Detection of an Interstellar Asteroid [PDF]

, 2017
The arrival of the robustly hyperbolic asteroid A/2017 U1 has potentially interesting ramifications for the planet-formation process. Although extrapolations from a sample size of one are necessarily uncertain, order-of-magnitude estimates suggest that ...
