What You Need to Know
The process lowers water activity below 0.6 by evaporative loss, which inhibits microbial growth. Concurrently, phenolic compounds undergo mild oxidation, concentrating sugars and organic acids while degrading heat‑sensitive nutrients such as vitamin C. The resulting product exhibits a denser matrix of sugars, acids, and oxidized polyphenols that contribute to its characteristic taste and aroma.
