Initially the total antioxidant activity, the total flavonoid contents, the total phenolic contents and the ascorbic acid were measured in fresh fruits. Then samples for freezing and vacuum freeze-drying were frozen what led to a decrease in total antioxidant activity by 11% (persimmon) - 28% (kiwi fruit), a reduction of total phenolic and total flavonoid contents for about 10% and the content of ascorbic acid decreases by 8% (kiwi fruit) - 30% (apple). The remaining frozen purees were…

Changes of hydrogen peroxide and radical-scavenging activity of raspberry during osmotic, convective, and freeze-drying.

Comparison and evaluation of drying methods confirmed superiority of freeze-drying; convective drying caused slight changes while osmotic dehydration showed a significant decrease of phenolic compounds and AO activity.

Dried Fruits: Excellent in Vitro and in Vivo Antioxidants

Dried fruits, especially figs, are a convenient and superior source of some nutrients, but in the American diet amount to less than 1% of total fruit consumed, the findings suggest that dried fruits should be a greater part of the diet as they are dense in phenol antioxidants and nutrients, most notably fiber.
