Abstract

Microfibrillated cellulose (MFC) with and without added CMC was exposed
to short-term dynamic thermal treatment using a steam jet cooker. The
effects of the elevated temperature (130 °C, ∼3 bar) and shear forces on
the rheology, crystallinity index, UV/VIS adsorption and water
retention were measured. Jet cooking increased the viscosity and gel
strength of the MFC and MFC/CMC mixture but with CMC alone a slight
decrease in viscosity was observed. The water retention capacity and
crystalline indices of the MFC were not greatly affected by the
short-term thermal treatment and shear forces, although a slight
increase in the UV/VIS absorbance was observed.
