In this study, the effects of four different drying processes, sun drying (SD), oven drying (OD), vacuum
oven drying (VOD) and freeze drying (FD) for tomatoes (Solanum lycopersicum) and ginger (Zingiber officinale)
in terms of thiolic and phenolic contents have been studied. Thiol content, total phenolic content
(TPC), ascorbic acid (AA) content, and cupric ion reducing antioxidant capacity (CUPRAC) were determined
in fresh and dried samples. Glutathione (GSH) and cysteine (Cys) were determined as the thiol
contents of tomatoes and ginger.
