Application of Polyamines to Maintain Functional Properties in Stored Fruits

Polyamines are natural compounds involved in many growth and developmental processes with ubiquitous presence in all cells. Research in fruits has been developed to get a better understanding of the role of polyamines, both endogenous and exogenous, especially during the ripening and senescence processes. However, in recent years and given the relationship between fruit consumption and human health, the study of antioxidant compounds responsible for these beneficial effects is of increasing interest.This chapter focuses on the role of polyamines on the content of bioactive compounds with antioxidant activity as well as in the activities of the main antioxidant enzymes in fruits.
