Honey and sugar syrups demonstrate several thermal or thermo-chemical parameters (phenomena), such as the glass transition temperature (Tg), along with their respective changes in enthalpy of fusion (?Hfus), and heat capacity (?Cp) which could be determined by DSC. The glass transition temperature (Tg) is an important physical parameter for determination of food adulteration and has been defined as the midpoint temperature in the range over which the transformation from liquid to amorphous state occurs at a given scan rate. This parameter is specific to each food component and product, although it may vary slightly depending on the thermal history of the material (as in the case of honey that has been warmed to a certain temperature to lower its viscosity). Tg values are strongly dependent on the amorphous phases of the material and respond to modification caused by the addition of an exogenous compound.
