“…Nutritionally, eggplant fruits constitute a valuable source of essential nutrients, including vitamins, minerals, and proteins, along with bioactive compounds like phenolic acids and flavonoids, which offer several health benefits [ 6 ]. Chlorogenic acid (5-O-caffeoyl-quinic acid; CGA) is the predominant phenolic acid in eggplant [ 7 , 8 ], noted for its potential health-promoting properties, including antioxidant, anti-carcinogenic, anti-inflammatory, analgesic, antibacterial, cardioprotective, and anti-diabetic properties [ 9 , 10 ]. However, the presence of CGA and other phenolic compounds plays a critical role in the postharvest quality of eggplant due to their susceptibility to enzymatic browning.…”

Eggplant (Solanum melongena L.) breeding for fruit quality has mostly focused on visual traits and nutritional and bioactive compounds, including chlorogenic acid. However, higher contents of chlorogenic acid may lead to more pronounced fruit flesh browning. We examined a diverse collection of 59 eggplant accessions across five varietal types (‘black oval’, ‘striped’, ‘anthocyanin-free’, ‘purple’, and ‘black elongated’) to evaluate the degree of browning, polyphenol oxidase (PPO) activity, and chlorogenic acid (CGA) content. The results reveal moderate correlations among these traits, with no clear differences among the varietal types, suggesting that other factors, including genetic variation, might significantly influence these traits. Notably, ‘black oval’ accessions demonstrated higher browning and PPO activity, whereas ‘striped’ accessions showed low variability. The identification of genotypes with lower browning and higher CGA content highlights opportunities for targeted genotype selection to improve eggplant chlorogenic acid content while maintaining low or moderate browning, pointing towards the importance of genetic considerations in breeding strategies to reduce browning and enhance nutritional value.
