In fact, the Spanish
chorizo studied in this paper (chorizo from northern Spain) is used
as an ingredient in typical Spanish stews with a long cooking time,
such as “fabada” (about 3 h). For this reason, this kind of chorizo
should not be too hard before cooking so as to allow its ingredients
to provide a good taste to the final dish. Synthetic casing
could hence reduce processing time to obtain the same hardness
as that of ChN.
