 Transit Temperatures of California Mature-Green Tomatoes Shipped by RailW. R. Barger, J. M. Harvey and S. M. Ringel No 311190, Marketing Research Reports from United States Department of Agriculture, Agricultural Marketing Service, Transportation and Marketing Program Abstract: Excerpts from the report Summary: Transit temperatures of mature-green tomatoes were compared in a conventional ice-bunker car equipped with electric fans, a Cargotemp car, and a mechanically refrigerated car. The Cargotemp car is a modified ice-bunker car equipped with a small diesel engine to power thermostatically controlled fans. Loads in all the cars were heavy enough to qualify for reduced freight rates. Temperatures fluctuated more in the conventional car than in the other two cars and approached the chilling point (50° F.) in the coldest positions in the load. Temperatures in the Cargotemp and mechanically refrigerated cars remained close to the thermostat settings of 55° F. Ripening in transit in the Cargotemp and mechanical cars was uniform and sufficient to permit marketing within a few days of arrival at the terminal market. The colder temperatures in the conventional car retarded ripening and reduced the percentage of salable fruit Keywords: Crop Production/Industries; Marketing; Research and Development/Tech Change/Emerging Technologies (search for similar items in EconPapers) Downloads: (external link) Related works: Export reference: BibTeX RIS (EndNote, ProCite, RefMan) HTML/Text Persistent link: https://EconPapers.repec.org/RePEc:ags:uamsmr:311190 Access Statistics for this paper More papers in Marketing Research Reports from United States Department of Agriculture, Agricultural Marketing Service, Transportation and Marketing Program Contact information at EDIRC. |
