Impact of air- and freeze-drying methods on total phenolic content and antioxidant activity of Fistulina antarctica and Ramaria patagonica fructification
Fistulina antarctica and Ramaria patagonica are wild edible fungi from Patagonia, which produce mushrooms that have been consumed since ancient times by those in local communities. Both species possess high protein and low fat contents and other bioactive compounds with remarkable antioxidant activi...

Fistulina antarctica and Ramaria patagonica are wild edible fungi from Patagonia, which produce mushrooms that have been consumed since ancient times by those in local communities. Both species possess high protein and low fat contents and other bioactive compounds with remarkable antioxidant activity. Drying is a widely and commonly practiced preservation technique that is cost-effective. However, the process of drying can have an impact on the levels of bioactive compounds. In this study, the effects of drying methods on the total phenolic content (TPC) and antioxidant activity in the fructification of F. antarctica and R. patagonica were estimated. The analysis was conducted using fructifications that were fresh-frozen, dried at 50, 60, and 70 & DEG;C, and freeze-dried. The TPC was significantly higher for the fructifications that were fresh-frozen and dried at 60 & DEG;C in R. patagonica (with values of 14.78 and 13.67 mg GAE/mg of extract, respectively).
