Processing tomato is an important crop in California, where more than 100,000 ha are produced annually ( Hartz et al., 2008 ). In recent years, drip irrigation has revolutionized production and increased fruit yield expectations; some California

Oregon and Washington produce 30% of the U.S. processed sweet corn with a 2009 farm market value of $120,512,000 ( U.S. Department of Agriculture, 2009 ). The majority is produced in the Columbia Basin (central Washington and north–central Oregon

The development of dark color is often a major problem in the processing of potatoes. This is due, in large part, to the reaction of reducing sugars with amino acids upon the application of heat during processing. Several chemicals have been shown which, when applied to foliage in the field, will decrease reducing sugars and dark color in processed potatoes.

Organic foods are produced using agricultural practices that emphasize renewable resources and conservation of soil and water. Horticultural crops are grown and processed without synthetic fertilizers, pesticides, ingredients and processing aids. Crops or ingredients derived from genetic engineering, and use of ionizing radiation are prohibited in organic production. The challenge is to deliver produce that has the same safety, quality and shelf life as conventional products, with a limited array of tools available for sanitation and postharvest treatments. Organic operators, professionals servicing the industry, as well as researchers involved in organic production practices, should be aware of all the points in the process of storing, handling and transforming horticultural crops where accidental contamination could occur, and thus compromise organic integrity. This presentation summarizes the major points of the National Organic Program for processing and handling, and gives suggestions for postharvest research. For example, finding organic alternatives for postharvest decay control is critical to maintain food safety. Additionally, ingredients compatible for fresh cut and produce coatings must be developed for the organic market for food safety and competitiveness.
