Missing ingredient

[limyw]

I sent my honey for analysis last week, and got the report this afternoon. Water 18.1%, sugar 62%, both made up about 80%. There is still 20% of content missing. What would be the likely ingredient that not being find out? To my understanding, honey only contains less then 1% of ash, and very low percentage of mineral and vitamin. They unlikely to be that 20%!
:idea:

I extracted the honey myself, using honey ectractor,  and very sure it does not comteminated, or added with other things. A polyesther screen was used to filter the honey.

That does not sound correct.  Here's a typical breakdown:

http://www.nhb.org/honmon/nutri.html

"17.1% water, 82.4 % total carbohydrate and 0.5% proteins, amino acids, vitamins and minerals. The average carbohydrate content is mainly fructose (38.5%) and glucose (31.0%). The remaining 12.9% of carbohydrate is made up of maltose, sucrose and other sugars."

Maybe that's a typo?
