As a result, antioxidant capabilities of tomatoes and ginger were
significantly affected by all of the drying techniques. The three drying
methods in which heat was applied caused more losses when
compared to the freeze drying method (Table 1). Unfortunately,
freeze drying is a costly procedure that limits its usage in the food
industry. Because fresh tomatoes and ginger are excellent sources
of antioxidants, the antioxidants in tomatoes and ginger should be
maintained by minimising the adverse effects of all technological
processes. This study aims to make consumers aware of the effects
of drying and that they should become accustomed to eating seasonal
fresh fruits and vegetables. Besides, antioxidant-rich freeze
dried tomatoes and ginger are becoming important sources for
functional foods that are increasingly popular today.
