Subject: [BEE-L] The origin of methylglyoxal in New Zealand manuka (Leptospermum scoparium) honey



interesting, so it is just a matter of adding some dihydroxyacetone to the

syrup to make any honey to be Manuka factorizable ...

Abstract



Methylglyoxal in New Zealand manuka honey has been shown to originate from

dihydroxyacetone, which is present in the nectar of manuka flowers in

varying amounts. Manuka honey, which was freshly produced by bees,

contained low levels of methylglyoxal and high levels of dihydroxyacetone.

Storage of these honeys at 37 degrees C led to a decrease in the

dihydroxyacetone content and a related increase in methylglyoxal. *Addition

of dihydroxyacetone to clover honey followed by incubation resulted in

methylglyoxal levels similar to those found in manuka honey.* Nectar washed

from manuka flowers contained high levels of dihydroxyacetone and no

detectable methylglyoxal.
