At the commercial harvest time (FFDS), ‘Aori27’ showed the lowest PPO activity among all cultivars, and no statistical differences were observed among ‘Elstar’, ‘Fuji’, and ‘Mellow’ (Table 1). Browning is an important factor in terms of quality loss during post-harvest storage of lettuce heads and minimally processed lettuce [1,2].
The effect of continuous high intensity light (HIL, 2500 lx), low intensity light (LIL, 500 lx), and darkness on FRL browning and quality was studied upon 7 d cold storage. The quality of iceberg lettuce is directly linked to this discoloration.
Profile, antioxidant potential, and applicability of phenolic compounds extracted from Spirulina platensis.
In conclusion, under the scope of this study, the results showed that among the studied cultivars, ‘Fuji’ is the most suitable for fresh consumption as a result of its higher phenolic content at commercial harvest time, and ‘Aori27’ is the best for fruit processing as a result of its low enzymatic browning (associated to the lowest PPO activity and the lowest polyphenol content).
