Module Contributor:Eamon Kealy
Module Description:The aim of this module is to provide the learner with the fundamental knowledge and skills to manage horticultural crops post-harvest. Learners will study keys topics such as pre and post-harvest physiology, eating quality and it's retention, controlled atmospheric storage, modified atmospheric packaging and post-harvest pests and diseases.
Learning Outcomes:
On successful completion of this module the learner will be able to
  1. Explain the importance of pre-harvest physiology for fruit and vegetables on the long term storage of horticultural crops.
  2. Deduce the importance of atmospheric composition on the eating quality and shelf life of horticultural crops.
  3. Evaluate the damage caused by post-harvest pest and diseases under different storage regimes.
  4. Contrast the design of controlled atmosphere stores and modified atmosphere packaging.
