ConclusionThe effectiveness of an antioxidant depends on many factors,including the application system, pH, substrate of application, stor-age condition etc. In in vitro studies, Hexyl was the best treatmentfor reducing browning in both the extract and precipitate. How-ever, in in vivo trials with fresh-cut ‘Rojo Brillante’ persimmon,Hexyl-treated samples were the most browned, indicating thatapplication of antioxidants has an effect not only on browning reac-tions, but also on metabolic activity and cell wall changes duringwound-induced reactions.AA and CA were the most effective treatments in reducingenzymatic browning of fresh-cut persimmon, reaching the limit ofmarketability in the range of 5–7 days. In particular, concentrationsof 1.12% AA and 0.21% CA seemed to be the most effective in con-trolling enzymatic browning. CaCl2also contributed to extendingthe shelf-life of persimmon pieces, however its effectiveness waslower than AA and CA.Future work will require a study of the effect of these antioxi-dants on the sensory quality of ‘Rojo Brillante’ persimmon and theircombination with other technologies, such as modified atmospherepackaging and edible coatings.
