Sugar levels in senescent leaf…

I found this post and screenshot recorded it. Fully yellowing Prilep on the plant followed by an oven stem-kill resulted in very sweet leaf…
Then I looked up some research papers and found this article:

Comprehensive investigation of tobacco leaves during natural early senescence via multi-platform metabolomics analyses​

Comprehensive investigation of tobacco leaves during natural early senescence via multi-platform metabolomics analyses - Scientific Reports

Senescence is the final stage of leaf growth and development. Many different physiological activities occur during this process. A comprehensive metabolomics analysis of tobacco middle leaves at 5 different developmental stages was implemented through multi-platform methods based on liquid...

It states that sugar levels seem to drop of as ripening progresses, but then rises sharply at full yellowing on the stalk.
Could “tobacco candy” be possible for anyone with patience, and no flue curing system?

If you pick it at the max sugar content, then denature the amylases that break down carbohydrates, it will be sweet tobacco. What is the minimum temperature for that? Probably talk to a brewer. I think it's around 165°F.

Without heating the tobacco, whether it's on the plant or not, the amylases will continue to break down starch into sugar, and sugar into carbon dioxide.

165? (Sounds about right-haven’t brewed in 10 years)
An oven or hot water bath (with plastic bagged leaves) could do that in any kitchen.

Tekst from a turkish farmer. (and google translate )

From sunrise in the morning to sunset in the evening, the leaf mixes the light, CO2 and nutrients it receives from the roots and soil and through its pores and stores them in the leaf. After the sun goes down, it begins to digest them one by one and puts them in a useful form. If we break tobacco in the middle of the day and in the evening, the nutrients in the leaf have not yet been digested, so when they are dried, they have a negative effect on the quality. However, since the nutrients in the leaves are well digested at the time when night turns to morning, the leaves broken in this way are better qualified when dry.

Has anyone tried this theory ??? Is there a difference if only air cured and exposed for sun. ??
