Specifities of postharvest technology of fruit crops (152073)
Course coordinator
Course description
On this module student acquire knowledge of physiological and biochemical processes in fruits after harvest of main fruit species. This module deals with cooling procedures, postharvest treatments in purpose of maintaining fruit quality and improvement of storability, physiological disorders that occur during storage, sorting and packing. On exercises students will learn how to recognize physiological disorders for specific fruit species. They will also visit cold storage facility where they will be familiarized with technological processes of storage and packing fruits.
