Excerpts from the report Summary: As recently as 1951, a scant 1 percent of the fresh carrots marketed were sold in prepackaged form. By 1956, about 85 percent were prepackaged. The change has resulted in substantial reductions in transportation charges, less spoilage, and better salability of the vegetable. This rapid shift grew at least in part from 10 years of economic and engineering research conducted by the U. S. Department of Agriculture and the industry. Most of the research has never been published, although much of it was demonstrational in character and has influenced many improvements in practices within the industry. This report describes the studies and findings in some detail, for the guidance of the carrot industry and for other industries that might find similar practices useful. The objectives of the research were (1) to reduce the cost of marketing carrots, and (2) to improve their salability.
