- Resumen
High pressure processing is a food preservation technique which can be an alternative to heat treatment. Pressurization, in theory, produces changes in organoleptic properties and antioxidant compounds to a lesser extent. The objective of the present dissertation has been to study the effect of high pressure processing on oxidative processes and their relation to the organoleptic qualities of diced swede and packaged sliced ham. The results have pointed to pressurization at 600 MPa, and produce an effective decontamination is that which causes less loss of compounds or antioxidant properties. For swede, this pressure level also caused a minor modification of the organoleptic qualities. This dissertation has also shown that depending on feed composition, the effect of pressurization on the organoleptic qualities can be diametrically opposite.
