Consideration of the interactions between decisions made at one point in the supply chain and its effects on the subsequent stages is the core concept of a systems approach. Postharvest Handling is unique in its application of this systems approach to the handling of fruits and vegetables, exploring multiple aspects of this important process through chapters written by experts from a variety of backgrounds.

Newly updated and revised, this second edition includes coverage of the logistics of fresh produce from multiple perspectives, postharvest handing under varying weather conditions, quality control, changes in consumer eating habits and other factors key to successful postharvest handling.

The ideal book for understanding the economic as well as physical impacts of postharvest handling decisions.

Key Features:
*Features contributions from leading experts providing a variety of perspectives
*Updated with 12 new chapters
*Focuses on application-based information for practical implementation
*System approach is unique in the handling of fruits and vegetables
