significant part of expanded food snacks have formulations,
which are based on potato ingredients. While there is a vast collection
of patents on these snacks, hardly any scientific research has
been performed on this subject. However, the making of expanded
potato snacks is quite reminiscent to the making of cereal-based
expanded snacks, and other processes involving the creation of vapour
bubbles in food via intensive heating, i.e. baking or puffing.
These related processes have been investigated more regularly in
the scientific literature (Moraru and Kokini, 2006). On their part,
expansion of food snacks is just one example within the larger research
area of food structuring
