Irradiation as a novel approach to improve quality of Tropaeolum majus L. flowers: Benefits in phenolic profiles and antioxidant activity

The increasing application of edible plants in several food commodities demands new technological approaches to improve their distribution and marketing as fresh products. Prolonging post-harvest storage, while preserving the whole quality of plants, these facts will benefit their industrial development, as well as the consumers' health. This study applied irradiation technologies, using electron-beam and gamma-irradiation in different doses, to a widespread and highly appreciated edible flower species, T. majus, and demonstrated that these technologies/doses did not compromise the phenolic compounds composition and antioxidant activity.
