    Malaysian honey is rich in nutrients and bioactive compounds, which can be a healthy alternative to refined sugar in food production. However, liquid honey’s viscous and sticky nature makes it unpreferable in industrial handling. This study, an atomization system coupled with vacuum drying to produce honey powders to overcome the problem. Three types of Malaysian honey, namely Acacia, Gelam, and Tualang, were encapsulated in Ca-alginate gel beads using the atomization system. The density viscosity, and surface tension of the honey-alginate solutions were measured, and the concentration of honey and alginate influenced the physical properties of the solutions. Honey-encapsulated gel beads in the size range of 2.16-2.92 mm were produced using the atomization system with the air-liquid mass flow rate ratios of 0.22-0.31, Weber number (We) of 112-545, and Ohnersorges number (Oh) of 0.35-10.46. Gel bead diameter can be predicted using a simple mathematical model. After vacuum drying, the honey gel powder produced was in the size range of 1.50-1.79 mm. Results showed that honey gel powders with good encapsulation efficiency and high honey loading could be produced using the atomization system and vacuum drying.

    Azadirachta indica (A. indica) and Clinacanthus nutans (C. nutans) is a traditional medicinal plant with a great medical impact on bacteria inflammation. They are few studies for the phytochemical and antimicrobial were conducted for both types of plants. Phytochemical analysis was performed using classical colorimetric methods, which is the folin-Ciocalteu method and aluminum chloride precipitation were employed for quantitative of total phenolic content (TPC) and total flavonoid content (TFC). Meanwhile, antioxidant activity was estimated by DPPH scavenging value. Antimicrobial activity was determined by using the agar well diffusion method against Escherichia coli (E. coli) and Staphylococcus aureus (Staphy. aureus). The methanol crude extract of A. indica and C. nutans showed low content of phenolic, 1.65 mg GAE/g, 0.18 mg GAE/g; flavonoid content is 43.56 mg QE/g and 26.07 mg QE/g respectively for both extracts. Meanwhile, the percentage of scavenging activity is 87.13% and 34.90% for A. indica and C. nutans. Regarding the antimicrobial activity, the A. indica extract inhibits the growth of target bacteria with a minimum inhibitory concentration of 31.25 mg/ml for both strains and almost no inhibitory concentration for C. nutans. Hence, aim this study is to determine two local plant varieties as a source of antimicrobial agents by used soxhlet extraction method.
