Pet Food Processing
Applying polymer science to petfood production
Polymer science — the study of the glass and melt transitions of polymers — has been developed and used by the synthetic polymer industry for many years. In recent years, the principles of polymer science have been applied to the petfood extrusion process to better understand and predict processing effects.
Understanding a raw material’s transition temperatures can be useful in predicting how a given ingredient might affect the petfood extrusion process.

The particle size and pre-grinding of raw materials is especially critical if the final product is a delicate shape. The samples on the left were ground through a 0.8 mm hammermill screen, the ones on the right through a 1.5 mm hammermill screen.
