Stingless bee (Tetragonula biroi Friese) honey from four provinces of the Philippines - namely, Batangas, Laguna, Quezon, and Albay - were characterized by their physico-chemical properties and botanical origin. Determination of color, moisture, electrical conductivity, ash, pH, acidity, hydroxymethylfurfural (HMF), total reducing sugars (TRS), sucrose, and melissopalynological analysis was done on honey samples. The color of the honey samples ranged from extra light amber to dark amber. The percentage moisture of the samples ranged from 22.0 ± 0.0 to 25.8 ± 0.3%; electrical conductivity ranged from 1.28 ± 0.10 to 2.52 ± 0.06 mS/cm; ash content ranged from 0.36 ± 0.05 to 1.27 ± 0.06%; pH values ranged from 3.7 ± 0.0 to 4.0 ± 0.0; total acidity ranged from 149.95 ± 3.45 to 264.44 ± 1.76 meq/kg; HMF content ranged from 18.39 ± 1.18 to 33.10 ± 0.61 mg/kg; TRS ranged from 34.90 ± 0.37 to 39.72 ± 0.07%; the sucrose content ranged from 1.09 ± 0.27 to 10.41 ± 0.26%. Results of the melissopalynological analysis showed 21 pollen types. The properties of honey significantly differ based on location and botanical origin. [ABSTRACT FROM AUTHOR] |
