Osmotic Dehydration of Apple Slices Using a Sucrose/CaCl_2 Combination To Control Spoilage Caused by Botrytis cinerea, Colletotrichum acutatum, and Penicillium expansum

摘要

The efficacy of sucrose combined with CaCl_2 during osmotic dehydration (OD) was tested for the control of Botrytis cinerea, Colletotrichum acutatum, and Penicillium expansum growth on lightly processed apple slices. The objective of this work was to determine whether the addition of CaCl_2 in the osmotic solutions would limit the proliferation of fungal decay organisms. Slices were submitted to OD for 1 h at 25 deg. C in solutions containing 5 to 65/100 sucrose. Calcium chloride was added to a similar set of sucrose solutions at 0 to 8/100.
