Academic Year 2016/2017

  • Teaching Mode: Traditional lectures
  • Campus: Bologna
  • Corso: Second cycle degree programme (LM) in International Horticultural Science (cod. 8883)

Learning outcomes

The course provides specific knowledge to identify and understand the key processing steps occurring in fruit processing. In particular, at the end of the course, the students will be able to: 1) describe the main steps required to produce processed fruits (such as cloud/clear juices, nectars, puree, jams, jellies and marmalades, ciders and distillates) and link them with the main unit operations characterizing hot and cold technologies used in fruit processing, including washing, peeling, enzyme treatments, pasteurization and sterilization. 2) evaluate the mass and energy balance of the main fruit processes. 3) understand the main chemical and microbial changes occurring to processed fruits, such as pectin jellification, yeast fermentation, enzymatic browning, juice sedimentation and the microbial thermal death
