Abstract

Differential scanning calorimetry (DSC) has been used to determine the oilcontent in dried olive pulp of Cassanese and Carolea tree cultivars and tofollow their inoliation trends from September to January. DSC was performed by cooling samples of olive dried pulp from -10 to -60 degreesC at 1 degreesC/min and the amount of oil calculated from the peak area obtained. The enthalpy and temperature range of the crystallization peak far the pure oilwere 61 J/g and -34 to -40 degreesC for the first cultivar and 54 J/g and -35 to -42 degreesC for the second one. The proposed DSC method is fast, specific, and reliable. It does not use solvents, requires smaller samples (<100 mg) than conventional solvent methods, and can detect real absence of water in the sample.
