Maybe there was some other form of preservation. Radiation works well,
as does simple heat sterilization.

GDL is commonly found in honey, fruit juices, and wine. Being acidic,
it adds a tangy taste to foods, though it has roughly a third of the
sourness of citric acid. It is metabolized to glucose; one gram of GDL
is equivalent to one gram of sugar.
