Latest Patents

Hale's latest patents include a process for isolating plant extract fractions, particularly focusing on essentially nicotine-free tobacco extracts. These extracts serve as tobacco flavorants and are described as stable, non-volatile, and relatively odorless under typical conditions. However, when thermally provoked, they deliver the characteristic flavor associated with tobacco. The preparation of these fractionated extracts involves contacting plant matter with a solvent to create a crude extract, followed by solvent removal and isolation of a fraction that provides the desired aroma and flavor through size exclusion chromatography. Additionally, he has developed a method to improve the sensory effect of cigarette smoke by using a disc to shape the smoke flow into a divergent pattern, enhancing the perceived flavor, especially in cigarettes with low particulate matter delivery.
