There is a rising number of visitors to Benefits of Honey writing to me and asking this question. Unfortunately, I don't really have a clear answer to this, but would like to share my experience and thoughts about this issue from a honey consumer perspective.
The term "adulterated honey" implies that the honey has been added glucose, dextrose, molasses, corn syrup, sugar syrup, invert sugar, flour, starch, or any other similar product, other than the floral nectar gathered, processed, and stored in the comb by honey bees. Legal standards and requirements for foods, including honey quality, and tests for honey adulteration vary widely amongst countries and some may not meet the wish of every consumer around the world.
food and nutrition labels. My take is always -- go for the trusted or more known brands. We all know that a "pure honey" label doesn't guarantee at all that it is not diluted with water and further sweetened with corn syrup; it just promises that there is real pure honey inside, with no suggestion of its amount. The law does not require a "pure honey" label to say how much pure honey is in the bottle. Also, prices are not always a good indication of quality honey. In food fraud cases, which happen a lot with Chinese honey, manufacturers can mix different honey floral blends and sell it as more expensive varieties such as Manuka honey. And so-called "local honey" may not be locally produced and processed local honey but cheap, low quality honey imported from other countries and then bottled and distributed locally.
Personally, when selecting honey in the shop, I think it's almost impossible to tell the bad from the good by just looking at the honey content through the bottle or studying its

Some of my web visitors strongly believe and teach that ants don't fancy pure honey and will not hover around it. It's hard to understand or believe this as there seems to be no reason why ants should favour processed sugar over honey and ants may not always be "available" at all places for a honey assessment ("no ants observed" may not necessarily mean pure honey). The reason why a sweet liquid is more attractive than another for the ants could also be due to other factors such as liquid density, flavors which vary depending on the floral types. Another test that is commonly discussed over the internet is the flame test which involves lighting up a cotton bud dipped into the honey with a match-stick flame. It's believed that the honey will burn if it's pure. I have tried this method many times using different types of honey, some of which I was very sure they're pure honey (e.g honeycomb honey), but the result I got was never consistent, and it seemed to depend very much on how much honey was dipped and how long the honey was exposed to the flame.
There's another simple way which I have tried to verify the purity of honey: Observe how liquid honey comes down into a glass of water. Pure honey does not immediately dissolve in water; you will notice that it takes a bit of effort to stir it in the water to dissolve the lumpy bits, whereas sugar tends to dissolve easily in a jiggery as you drop them into the water. However, test result is sometimes not that clear because different honey varieties have different viscosity, some are denser and thicker than others, and obviously honey in cream form, even if it's adulterated with other substance, will not dissolve as easy as liquid honey in water.
It is suggested that people who are used to tasting honey may be easier to detect any added sugar. But frankly, because there are just too many floral varieties and blends, and the amount of adulteration may not be sufficient to affect the taste and aroma of the honey, even though I frequently take honey, I am still not 100% certain about my suspicion
