>How does one go about measuring electrical conductivity in honey or honeydew?
I found this. It involves the use of a conductometer. The test subject is diluted with water at a controlled temperature and a probe from the conductometer is placed in the solution.
> After the probe is placed in the liquid to be measured, the meter applies voltage between two electrodes inside the probe. Electrical resistance from the solution causes a drop in voltage, which is read by the meter. The meter converts this reading to milli- or micromhos or milli- or microSiemens per centimeter.
Forest honey, aka honeydew, has high electrical conductivity.
>The conductivity is very often used in routine honey quality control. This property of honey is considered very good criterion for assessment of botanical
origin and purity of honey. Among other things, honey contains components such as organic acids and minerals, which in an aqueous solution have the
ability to dissociate into the ions or to conduct an electric power. The bright colour of honey usually points to a lower conductivity than dark colour of
honey (Kropf et al., 2008). The electrical conductivity of honey is defined as that of a 20% weight in volume solution in water at 20° C, where the 20% refers
to honey dry matter (International Honey Commission, 2009). The measurement of electrical conductivity points indirectly to the ashes content of honey
(Accorti et al., 1987). The ashes of honey give an indication of environmental pollution and hence also an indication of geographical origin. The electrical
conductivity of the honey is related to the concentration of mineral salts, organic acid and proteins and proved to be useful for discriminating honeys of
different floral origins.
> The data indicated lowest conductivity in acacia honey samples, while the
highest conductivity is found in samples of forest and linden honey.
