The aim of the research was comparison of microwave-convective and convective (at temp. 70ºC) drying influence on radical scavenging activity and polyphenols content of dried apples. Microwave drying shortened the time of drying even of 63% in comparison to convective drying. Radical scavenging activity and polyphenols content in the dried material, received with the use of 300 W microwave power, were similar or even higher level than in the raw apple. Significant decrease of the radical scavenging activity of 21-26% and polyphenols content was caused by the use of lower microwave power (150 W), but the value was quite lower than in case of apples received by the convective drying.
