Abstract
- To explore the degradation rule of anthocyanin subjected with different environmental factors and food matrices, the effects of different temperatures (4~100 °C), illumination conditions (avoiding light, sunlight, and ultraviolet), freeze-thaw cycles (5 times), sucrose additions (0 ~ 20%) and NaCl additions (0 ~ 5. 0%) on the anthocyanin retention were investigated, and their degradation kinetic models were further established. Results showed that, with the temperature increasing from 4 °C to 100 °C, anthocyanin retention of 10 h decreased significantly from 88. 19% to 28. 10%, and their half-life time (t1/ 2) decreased from 55. 0 h to 5. 9 h(P<0. 05). Com- pared with avoiding light, both anthocyanin retention of 10 h and t1/ 2 under ultraviolet were the lowest (84. 41% and 43. 0 h). After five freeze-thaw cycles, anthocyanin retention of 120 h was reduced to 85. 21% with the corresponding t1/ 2 of 612. 6 h. During 80 °C of stability acceleration experiment, both anthocyanin retention of 10 h and their t1/ 2 reached the highest value (60. 17% and 13. 7 h) with sucrose addition of 10%, and the above values also reached the highest value (54. 63% and 11. 3 h) with NaCl addition of 5%. The storage and processing of anthocyanins should avoid high temperature, ultraviolet and freeze-thaw cycles as much as possible, and appropriate amount of sucrose and NaCl could be added to enhance the stability of antholyanins.
