Sterilization is a critical step in the manufacture of wet petfood. Its aim is to guarantee the microbiological safety of products during their shelf life. Sterilization also has a great influence on flavor development (mainly through Maillard reactions) or off-flavor generation. Thus, sterilization is considered a key factor for wet petfood palatability.
