Abstract
Excerpts from the report Introduction: It is well known that cranberries keep best at low temperatures (36°-40°F). Previous studies have shown, however, that tight loads of warm (nonprecooled), prepackaged cranberries packed in master cartons cool slowly in transit, especially in the middle layer of the loads. In view of these findings, further tests were conducted in 1957 with the following objectives: (1) To determine the practicability of cooling cranberries before shipment, (2) to compare transit temperatures of precooled and nonprecooled packaged cranberries packed in master cartons, and (3) to determine the effect of precooling on development of decay and on keeping quality. This study is part of a continuing program of research designed to reduce the cost of marketing farm products.
