Salts were coated on a variety of thick food targets. The best transfer efficiency, adhesion (>70%), and percent side coverage (100%) were obtained when small (<200 μm) and cohesive (Hausner ratio > 1.20) salt was used with electrostatic coating on targets with high aw (>0.7), low resistivity (<9 × 108 Ωm), and short charge decay time (<3.8 s). Shape of salt also affected the coating performance; porous cube provided significantly better transfer efficiency and adhesion than flake salt on some targets. There was no significant effect of KCl content on coating performance.
► Salts were coated onto foods and other targets. ► The best coating was from electrostatically coated small, cohesive salt. ► The best targets had high aw, low resistivity, and short charge decay time. ► Shape of salt also affected the coating performance. ► There was no significant effect of KCl content on coating performance.
