Although the legal limit for CaCl2 in processed vegetable
products is 0.4 g/100 g, the levels used in this study were
selected to interact at the customary levels of NaCl
currently used. In this study, the addition of calcium in
the form of CaCl2 at 8 or 15 g/100 g affected the
fermentation of pepper mash by releasing more soluble
sugars, increasing alcohol and decreasing pH compared to
control or other treatments. These effects were immediate
upon the addition of CaCl2 to the pepper mash which was
apparent when these treatments resulted in increased
temperature (not measured—hot to the touch) during
formulation. The heat of hydration for CaCl2 is 395 kcal/
mol compared to 104 kcal/mol for NaCl (Whitten &
Gailey, 1981, Chapter 10). Although PE activity and
temperature was not directly measured in this study, PE
activity was higher for CaCl2 treatment demonstrated by a
higher concentration of alcohol and acid (Pe´rez-Alema´ n,
et al., 2005).
