In this study, the emulsification properties of a native biopolymer namely Angum gum (Ang) for use as a
food flavor encapsulant in spray drying encapsulation was investigated and the results were compared
with Arabic gum (Arg) stabilized emulsions. After gum extraction, gum dispersions with maltodextrin
were prepared in water (in 1–5% concentrations) and emulsified with 5 and 10% d-limonene using high
pressure homogenization. Statistical analysis of emulsion droplet size data revealed a significant difference
between flavor level, gum type and droplet size at ˛ = 0.05. The results showed that increasing the
Arg level leads to a decrease in emulsion droplet size, while increasing Ang content results in bigger
droplet sizes. However, no significant differences were observed in droplet size. Also, droplet size data
revealed that Ang-emulsified droplets at 2% gum and 5% flavor level had the lowest d32, d43 and the
highest specific surface area by high-pressure homogenizer which could be mentioned as the optimum
level of this native gum.
