Modeling Blueberry Firmness and Mass Loss During Cooling Delays and StoragePublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Paper number 026009, 2002 ASAE Annual Meeting . (doi: 10.13031/2013.9712) @2002Authors: Mark K. Tetteh, Stanley E. Prussia, D. Scott Nesmith, Brahm P. Verma Keywords: Postharvest, storage, marketing, prediction Blueberry mass and firmness losses in postharvest environments were measured to determine the effect of cooling delays at selected temperatures. Models were developed from the slopes of mass and firmness values plotted against time for four temperatures (4, 21, 27 and 32 C). The models were evaluated by holding other sets of blueberries at three temperatures (21, 27 and 32 C) and at high relative humidity (95 %) for cooling delays of 0, 2, 4, 8, 12 and 24 hours before storage at 4 C for 24 or 96 hours. Good correlations among predicted versus observed data showed that it was possible to model the mass and firmness losses of blueberries at different temperatures and cooling delays. The impact of cooling delays was less than expected when compared with losses caused by low temperature storage for only four days. (Download PDF) (Export to EndNotes)
