Effects of different drying methods and storage time on free radical scavenging activity and total phenolic content of cosmos caudatus

Effects of different drying methods and storage time on free radical scavenging activity and total phenolic content of cosmos caudatus

The present study was conducted to determine the effect of air (AD), oven (OD) and freeze drying (FD) on the free radical scavenging activity and total phenolic content (TPC) of Cosmos caudatus and the effect of storage time by the comparison with a fresh sample (FS). Among the three drying metho...
