This study examines the physicochemical properties of stingless bee honey from SE Asia (Thailand). Twenty-eight stingless bee honey samples, from 11 stingless bee species, were examined. Results reveal an average color (67 ± 19 mm Pfund), moisture (31 ± 5.4 g/100 g), ash (0.531 ± 0.632 g/100 g), electrical conductivity (1.1 ± 0.780 ms/cm), pH of (3.6 ± 0.198), total acidity (164 ± 162 meq/kg), diastase activity (1.5 ± 1.6 °Gothe) and hydroxymethylfurfural (8.7 ± 12 mg/kg). The carbohydrate profile is: total sugar (51 ± 21 g/100 g), fructose (17 ± 9.7 g/100 g), glucose (14 ± 8.6 g/100 g), maltose (41 ± 15 g/100 g) and sucrose (1.2 ± 2.7 g/100 g). These findings are not dissimilar to those reported for stingless bee honeys from the neo-tropics. When compared with the Apis mellifera standard, stingless bee honey is characterized as possessing higher moisture content, acidity, ash and HMF but a lower level of total sugars.

Invited for a cover feature this month is the research group of Asst. Prof. Dr. Chularat Wattanakit from School of Energy Science and Engineering, Vidyasirimedhi Institute of Science and Technology (VISTEC), Thailand. The cover picture shows the facile synthesis of Sn, Ge, and Zr isomorphously substituted MFI with hierarchical structures by a one‐pot hydrothermal process. These designed materials illustrate the promising catalytic performance in glucose isomerization to fructose. More information can be found in theFull Paper by Chularat Wattanakit, and co‐workers.
