The extent of color degradation during thermal processing provides
the stability and acceptability of any green vegetables. The
rate of color degradation of the puree (leaf with and without stem)
was determined by linear regression of ln (1 f) vs. heating time at
selected temperatures. Green color degradation kinetics of leaf puree is illustrated in Fig. 1. It is evident from the figure that the
color degradation of rocket leaves puree followed first order reaction
kinetics adequately. The R2 values were greater than 0.98, and
the standard error was less than 0.09 in all the cases.
