| Summary: | Spray drying is an important method in the food industry for the production of
encapsulated oil to improve the handling and flow properties of the powder. In
this study, the effect of mixture of polymers on the encapsulation of fish oil by
spray drying was investigated. Fish oil powder were produced using different
ratios of mixtures of hydroxypropyl methylcellulose (HPMC) 15 cps and HPMC
5 cps. Scanning electron microscopy and the amount of extracted oil from the
surface revealed that the formulation containing high concentration of polymer
mixture provided the highest protective and prolonged effect on the covering of
fish oil. The particle sizes of less than 60 μm were obtained for all the formulations.
The powder density was very suitable, which improves the flowability of the
powder. Microencapsulation efficiency (69.16–74.75%) and surface morphology
of encapsulated oil showed that the stability was increased and hence increased its
acceptability as alternative primary polymers |
