Abstract: The measurement of the refractive index of sugar solutions is used as a rapid method for the approximate* determination of dry substance content.
The method can be used with plant juices, syrups, marmalades and jams.
In high purity sugar solutions, it is used as a measure of sugar content.
*NOTE - For a pure solution of known composition, the refractive index measurement gives the exact dry substance content of the relevant sugar.
For technical solutions which have additions of unknown non-sugars, the refractive index measurement gives the dry substance content in a more
or less good approximation, depending on the purity of the solution.
