  1. Data are presented as the mean ± standard deviation for n = 3.
  2. Means with distinct lowercase superscript letters (a–e) in the same column are significantly different (p ≤ 0.05).
  3. Control : soymilk without any encapsulating materials.
  4. MD 100 : encapsulating material containing solely maltodextrin.
  5. AG 100 : encapsulating material containing solely Acacia gum.
  6. MD: AG (40:60) : Maltodextrin and Acacia gum in ratio 40:60.
  7. MD: AG (50:50) : Maltodextrin and Acacia gum in ratio 50:50.
  8. MD: AG (60:40) : Maltodextrin and Acacia gum in ratio 60:40.
