The aim of this study was to assess the effect of chemical composition of honey and environmental
factors such as pH, storage temperature and ionic strength on cream formation in honey lemon tea drink. The
results showed that minerals, Ca2+ and Mg2+ were involved in cream formation while Fe2+ participated in
changing color to tar black at pH 4.12 and above. Honey rich in polyphenols and proteins increased the cream
to 2.51%. High proline content (0.506 mg/g) induced creaming in GH (Germany Honey) infusion while Ca2+
and Mg2+ were responsible for creaming in CH (Chinese Honey) infusion. The higher the amount of the total
solids in honey, the higher the amount of cream formed. Honey lemon tea creaming can be reduced by
controlling interaction between proteins and polyphenols, by pre-treatment of honey (i.e., to remove colloidal
matters) or by removing Ca2+ or Mg2+.
