The higher firmness of muffins
with inulin added as powder might be attributable to
insufficient gel structure formation, shown for wheat
bread by O’Brien et al. (2003). Cohesivity, which is the
force fraction that is necessary to compress the crumb to
a predefined deformation level (Baixauli et al., 2008a),
was lowest for the formulation containing the gelled
inulin and highest when Fibruline S20 was used.
