The sorption properties of yapunyah (Eucalyptus chropholia) and yellow box (Eucalyptus melliodora) honeys (Australian unifloral honeys) were investigated in a controlled relative humidity (RH) environment at 30 ◦C for 71 days. The original water activity of the honeys affected the sorption properties. These two honeys absorbed moisture at and above 67.9% RH and desorbed moisture at and below 51.4% RH. The crystallisation behaviour of tea tree (Melaleuca quinquenervia) and yapunyah honeys was studied during storage at 13 and 23◦C. The degree of crystallisation wasmonitored by measuring the absorbance at 660 and 665nm using a spectrophotometer. The heat-treated honeys did not show any sign of crystallisation after 5months, whereas a seeding with precrystallised honey induced crystallisation of the same honeys. This crystallisation was more rapid at 13 than at 23 ◦C.
