The extrusion process can involve simple formulations such as the ones used for snack foods consisting of simple starch or very complex formulations as the ones used in pet food diets which involve several ingredients. The latter are designed specifically to meet the nutritional requirements of the target species. In contrast, snack foods are designed to indulge the consumer. Not only does each ingredient in the formula play an important role in the amount of nutrients it supplies, but each also interacts with others during the process to produce the final product. Depending on the processing conditions and the ingredients used, different products can have an effect on the physical attributes (e.g. expansion) of the finished product as well as organoleptic properties (e.g. texture, flavour, mouth feel etc.).
