Excerpts from the report: Bruising injury is a major problem in marketing fresh tomatoes. The problem is aggravated by the numerous handling operations necessary in marketing; also, the obscurity of symptoms of internal bruising has tended to conceal the importance of the damage. The purpose of this study was to determine the nature and symptoms of bruising injury, to determine the extent of damage under laboratory-controlled treatments, and to report the amount of bruising injury found in a limited survey of commercially handled tomatoes at the time of unloading at a terminal market and during ripening and repacking.
