Dear Harro,

All honey samples that we have analized gave results lower thatn -20o/ooo
delta13-C but one, that gave a value of -19.2o/oo.
This sample is suspicious of adulteration. However, there is a second
alternative: The sample comes from the mediterranean coast of Spain, where
citrus plants are abndant. The AOAC admits that citrus honey may be
isotopically heavier that "normal" honey, so the possibility of having
a heavy honey and still be genuine should be considered, as alredy suggested by
other replyies.

However, a -11 0/o/oo honey does seem to be a litle totle too "bitter" to wswallow.

I'm interested in the subject, and I would appreciate being kept informed
omn developments ...
