The collection efficiency of a fiber is defined as the ratio of the number of particles striking the fiber to the number which would strike it if the streamlines were not diverted [Dorman, 1966]. For particles with dp > 1 pm, the particles are collected primarily by inertial impaction and interception. Collection by diffusion is only important for submicron particles. In the following, we only discuss the methodology of collection efficiency by interception. Details about the filtration of fine and ultrafine powders or granular filtration in general can be found in Davies (1973), Fuchs (1964), Dickey (1961), Matteson and Orr (1987), and Tien (1989).

The objective was to encapsulate a vegetable oil (representing a model for aroma compound) into a powder. The oil (ISI04) (VO) will be at a concentration of 5% TS into a matrix made of maltodex-trin MD (DE 12) and acacia gum (AG) (3/2 MD/AG). The composition of matrix was defined in a previous research work on encapsulation of aroma by spray-drying (Bhandari et al., 1992 Turchiuli et al, 2005 Fuchs et al, 2006).
