Polymorphism, microstructure and rheology of butter. Effects of cream heat treatment.

The effect of cream heat treatment prior to butter manufacturing, fluctuating temperatures during storage and presence of fat globules vs. no fat globules was examined in laboratory scale produced butter. X-ray diffraction and differential scanning calorimetry was used to study crystallization behaviour and nuclear magnetic resonance to measure solid fat content and water droplet size distribution.

Reduction of salt in pork sausages by the addition of carrot fibre or potato starch and high pressure treatment.

The combined effect of high pressure processing (HPP) (400, 600 and 800 MPa) and carrot fibre (CF) and potato starch (PS) on low salt (1.2%) pork sausages was investigated and compared with high (1.8%) salt sausages.

Synergistic cooperation of high pressure and carrot dietary fibre on texture and colour of pork sausages.

In order to investigate the synergistic cooperation between high pressure treatment (HP) and carrot dietary fibre, two formulations of pork sausages containing different percentage of carrot dietary fibre were pressurized at 500 and 600 MPa, for 1 second, 3, 6, and 9 min at 40, 50, and 60 °C. HP treatments significantly increase Young's Modulus and affect Hencky strain values. We conclude that HP processing and carrot dietary fibre markedly improved emulsion strength resulting in firm sausages.
