It can be concluded that a high free fat content in powders
induces coalescence upon reconstitution in water; which lead to
quick destabilization. Further investigation should be done considering the impact of the formulation, especially the protein type, on the free fat content in fines. Nevertheless, in the final product studied here, the amount of fines is too low to have a direct effect on the quality of the final reconstituted emulsion. This is especiallytrue for fines 2 which have the lowest stability
The new instability indexes generated in this article, based on
fat droplet distribution of reconstituted emulsions, could be applied on any kind of liquid emulsions that undergo aggregation and/or coalescence.
