POST HARVEST – PRODUCT INTEGRITY through the CHAIN PROGRAMME

HORTGROscience 2014 Product Integrity through the Chain (Post-Harvest) Programme is managed by Richard Hurndall.

The essence of this programme is to support and enhance the processes across the supply-chain to ensure that intrinsic product integrity is maintained, and that a quality product is available to the end-consumer in local and distant global markets. The objective of this Investment Focus Area (IFA) is to increase the marketable tons of fruit delivered per ton of fruit loaded.

The themes of this programme include:

  • Protocols and fruit quality maintenance
  • Storage techniques
  • Market access
  • Decay control
  • Fruit quality prediction
  • Chemical residue reduction/alternatives
  • Packaging
  • Transportation systems

FEMA – A Blushing Success

The Forelle Early Market Access (FEMA) programme is one of South Africa’s great export stories. Today South Africa has a virtual monopoly on the “blush” pear industry, with the Forelle as the second most produced pear per volume in South Africa. Read all about this phenomenal journey and the incredible return on investment that researchers brought about for the industry.

BRUISING AND ITS CONTROL
Bruising or physical damage to the apple causes unnecessary losses to the grower. With good management, this can be almost totally controlled.

IDENTIFICATION OF BITTER PIT IN APPLES
Most of the research in this area attributes bitter pit to a lack of sufficient Ca (calcium) (2; 1), but there are reports indicating the probability that bitter pit is due to excess Ca in the cell (8). A deficiency in Ca in the fruit can be due to cultural practices, hormonal regulation via fruit-shoot competition, as well as morphological factors and Ca transport in the plant. This has been reported on comprehensively by various researchers (2; 11).
