Suitable coating material for microencapsulation of spray-dried fish oil
This study was conducted to screen the most suitable coating material for the production of microencapsulated fish oil powder using ternary blends of maltodextrin (15, 25% w/w), Arabic gum (2.5, 7.5% w/w), and methylcellulose (0.5, 1.5 % w/w). The physical properties of fish oil emulsion and en...

| Summary: | This study was conducted to screen the most suitable
coating material for the production of microencapsulated
fish oil powder using ternary blends of maltodextrin (15, 25%
w/w), Arabic gum (2.5, 7.5% w/w), and methylcellulose (0.5,
1.5 % w/w). The physical properties of fish oil emulsion and
encapsulated powders were evaluated. Arabic gum (5% w/w)
showed the most significant (p<0.05) effect on the surface
mean diameter of the droplets in the emulsion. Maltodextrin
had the most significant (p<0.05) effect on the centrifuge
stability of the emulsion and the amount of surface oil of the powder at 15 and 20 % (w/w) respectively, whereas methylcellulose (0.5%w/w) had the most significant (p<0.05) effect on the width distribution of the droplets in the emulsion. The total optimal area leading to the formation of coating material with desirable physical properties was expected to be obtained by the combination of 16 % (w/w) maltodextrin, 6.5 % (w/w)Arabic gum, and 0.88 % (w/w) methylcellulose respectively. |
