The shelf life of horticultural produce can be extended by cooling it as soon after harvest as possible. A convenient way of cooling fruit and vegetables is to spray them with chilled water in devices known as hydrocoolers. However, to conserve water and energy the water must be recirculated around the system and the water contacting the produce is mandated to be potable. As a result, an effective water treatment system must be incorporated into hydrocoolers, and it is noted that a program of testing the water must be implemented. It is also reported how engineering science can be used to improve the design of hydrocoolers. 2006-09-26 published public lecture 5 VicWater Annual Conference Geelong, Victoria, Australia 28-29 September 2006 conference UNSPECIFIED FALSE ACIAR (2004) Reducing spoilage and contamination risks of fresh vegetables in China and Australia (ACIAR project PHT/1999/081) reported in http://www.linkingfarmerswithmarkets.net/ ADWG (2004) Australian Drinking Water Guidelines, National Health and Medical Research Council, Australian Government, Canberra, Australia AFFA (2001) Guidelines for on-farm food safety for fresh produce, Department of Agriculture, Food and Fisheries - Australia, Australian Government, Canberra DPI (2005) Priorities for action: Victoria- horticultural industries 2005-2008.
