Skim milk showed the same rates of cohesion and adhesion. However, the maltodextrin (DE 18) showed lower overall deposition rates than for skim milk, and particularly a lower rate of adhesion than for the subsequent cohesion of particles to each other after the initial spraying period. Previous workers have also noted the differences in the cohesiveness and adhesiveness of maltodextrin. The higher glass transition temperature for dry maltodextrin than for dry skim milk is also consistent with the lower deposition rates with maltodextrin.
