Enrichment of extruded snacks with tomato derivatives enhances
their nutritional attributes by adding lycopene and fibre.
This work has shown that lycopene can be retained in the extruded
snacks. Although the amount of lycopene retained after extrusion
was very low, variation in the chemical composition of the base
ingredients especially increases in the starch content, improved
the retention values. Furthermore, if physically resistant material,such as tomato skin is used as a source of lycopene, higher levels
can be retained in the final product.
