Polyphenol Degradation Kinetics of Specialty Coffee in Different Presentations

Polyphenols are chemical compounds found in plants, and coffee is an important source of them. The objective of the study was to evaluate the kinetics of polyphenol degradation in a blend of specialty coffee (green, roasted and roasted–ground beans), packaged in eight different packages, under accelerated storage conditions. The samples were stored at 40, 50 and 60 ◦C for 12, 8 and 4 days, respectively. The degradation kinetics were modelled based on chemical kinetics and determination of the...
