The stability of purple carrots anthocyanin on duration time at various temperatures ranged between 80 °C and 100 °C is evident in Table 7. Results indicated that little changes in anthocyanin extracted from purple carrots was observed after 90 min at 80 °C, and the destruction of anthocyanin was 9.0% at 90 °C after holding for 90 min at 90 °C. On the other hand, the remaining of anthocyanin were being 85.0% of the total anthocyanin pigments after holding for 180 min at 100 °C. Consequently, the holding of pigments at 80, 90 and 100 °C for 120 min caused a reduction of 6.0, 10. 0 and 12.0% while the corresponding results were 7.0, 12.0 and 15.0% after 180 min for the total anthocyanin pigments respectively.
