In the overcooking tests conducted in this study, calcium
salts were not effective in preventing the formation of acrylamide
in deep-fried shrimp chips, except with 0.1% calcium
lactate. The addition of 1% calcium acetate actually enhanced
the formation of acrylamide (Fig. 4); therefore, the addition of
calcium salts seems to be a less important factor in preventing
acrylamide formation than are the choice of puffing method
and the avoidance of overcooking. Acar et al [8] observed that
a lower amount of calcium and a higher amount of lactate
increased acrylamide formation. Raw shrimp chips fortified
with 0.1% and 0.5% calcium salts had an increased tendency to
form acrylamide during deep-frying (p > 0.05).
