The firm adhesion of flavouring particles onto crisp surfaces during coating processes is a major
concern in the snack production industry. Detachment of flavouring powders from products during handling and production stages can lead to substantial financial losses for the industry, in terms of variable flavour performance and extended cleaning down time of fugitive particle build-up on process equipment. Understanding the adhesion strength of applied bulk particulates used for
flavouring formulations will help analysts to evaluate the efficiency of coating processes and potentially enable them to assess the adhesion strength of newly formulated flavouring powder prior to commitment to full scale plant trials.
A rapid prototype of a novel adhesion tester has been designed and constructed. The apparatus
operates according to the principle of impact force acting on particles attached to the surface of the
food substrate. The main component is a circular plate to which four sample holders are attached
and which is subjected to vertical travel down a guide shaft. Several flavouring powders have been tested extensively. By plotting the detachment versus impact
force, the difference obtained between adhesion strength of different flavouring powders (which is a
strong function of particle size) has been discussed.
