Kinetic of Anthocyanin Degradation of Butterfly Pea Petal in Drying Process and Storage
The aim of this research was to determine the kinetics of anthocyanin degradation of butterfly pea petal during drying process and storage stages. Four level of temperatures were used in the drying process. the four temperatures were 40, 50, 60, and 70‚Äö?Ö‚àûC. Along with the determination of the kinetics of anthocyanin degradation, the kinetics of moisture content in drying process was also studied. For the storage stage, 25, 37, and 47‚Äö?Ö‚àûC were used as the storage temperature. the method that was used for the anthocyanin content analysis was the pH differential method. Results showed that the kinetics of moisture content during the constant drying rate followed the zero-order kinetics reaction, while the falling drying rate followed the first-order. the changes in monomeric and polymeric anthocyanin contents did not affected by the drying temperature and time. in the storage stage, the kinetics of monomeric anthocyanin content degradation followed the first-order kinetics reaction. Storage in lower temperature showed higher anthocyanin stability.
