The effects of temperature and pressure on the % AA are complex.
While at 40 and 60 ◦C the % AA increases with pressure from
10 to 20 MPa, the ANOVA data show significant differences from
these data. At 50 ◦C, no detectable pressure effect was observed by
ANOVA evaluation. Also, the maximum % AA value was detected at
60 ◦C and 20 MPa. An increase in % AA was observed at 20MPa with
enhancing temperature, while at 30MPa the % AA decreased with
temperature, although all treatments are statistically equals.
