Polyphenols are the most important phytochemicals in our diets and have received great attention due to their broad benefits for human health by suppressing oxida- tive stress and playing a protective role in preventing different pathologies such as cardiovascular disease, cancer, diabetes, and obesity.

Abstract

Polyphenols are the most important phytochemicals in our diets and have received great attention due to their broad benefits for human health by suppressing oxida- tive stress and playing a protective role in preventing different pathologies such as cardiovascular disease, cancer, diabetes, and obesity. The stability of polyphenols depends on their environments of processing and storage, such as pH and temperature. A wide range of technologies has been developed to stabilize polyphenols during pro- cessing. This review will provide an overview of the stability of polyphenols in relation to their structure, the factors impacting the stability of polyphenols, the new products deriving from unstable polyphenols, and the effect of a series of technologies for the stabilization of polyphenols, such as chemical modification, nanotechnology, lyophiliza- tion, encapsulation, cold plasma treatment, polyphenol–protein interaction, and emul- sion as a means of improving stability. Finally, the effects of cooking and storage on the stability of polyphenols were discussed.
