A comprehensive story of pea peptides and pea polyphenols: Research status, existing problems, and development trends

Pea peptides and pea polyphenols have gained much attention for their potential nutrition and health benefits, such as antibacterial, antioxidant, anti-inflammatory and hypoglycemic, showing great application potential in developing functional and healthy food. This paper provides a comprehensive review of the preparation technologies, bioactive activities and potential application fields, describing the research status, existing problems and development trends of pea peptides and pea polyphenols. Besides, the antioxidant, antibacterial, antidiabetic, and blood pressure lowering activities of pea peptides, as well as the current research status of delivery systems were mainly summarized and discussed. Additionally, the combination of pea peptides/polyphenols with other nutrients to develop new functional food ingredients will spark a trend in the development of plant-based nutritional health foods. This review will provide clear research ideas for further in-depth research and application of pea peptides and pea polyphenols, and point out the direction for scientific researchers committed to pea research.
