Semi-moist snacks are usually challenging to produce. The wanted hard texture is possible to obtain by using high levels of the starch. However, starch can give high stickiness during production and in some cases an expansion giving the snack a bubbly surface and uneven appearance.

The stickiness of the product during production is among the most significant challenges:

  • Lowers capacity, as it slows down the extruder
  • Causes snacks with uneven shape
  • Sticking after the extruder-die causes the clumping in pneumatic transport causing blockage along the production line
