Physico-chemical parameters such as melting point, density, acid value, iodine absorption number, and saponification value were determined for different beeswax samples extracted from the honey combs of Apis mellifera Linneaus, A. Cerana Fabricius, A. Dorsata Fabricius, and A. Breviligula Maa taken from three different locations in the Philippines. The average mean values calculated from A. Mellifera, A. Cerana, A. Dorsata, and A. Breviligula, respectively, are as follows : melting point (in deg C): 62.81 ± 0.18, 64.35 ± 0.17, 59.28 ± 0.18, and 59.44 ± 0.24; density (in g/mL) : 0.9546 ± 0.0035, 0.9611 ± 0.0092, 0.9838 ± 0.0167, and 0.9691 ± 0.0109; acid value (in mg KOH/g) sample) : 16.22 ± 0.23, 5.90 ± 032, 5.21 ± 0.28, and 4.68 ± 0.25; iodine absorption number (in g/100 g sample) : 4.35 ± 0.39, 4.70 ± 0.42, 4.52 ± 0.38, and 5.41 ± 0.23; and saponification value (in mg KOH/g sample) : 94.20 ± 4.92, 99.2 ± 2.2, and 94.9 ± 3.9.
