Cornelian cherry was dehydrated using different drying techniques: namely natural, microwave, convective, and combined drying. The moisture content of cornelian cherry was reduced from 72.56% to 10.27%. The color parameters closest to the fresh samples were measured at 50 °C, 70 °C, 90 °C, and at 100 and 300 W. Both fresh and dried cornelian cherries show high antioxidant capacity and comprise of various polyphenolic compounds. TEAC is the most suitable method for determining the total antioxidant capacity of cornelian cherry. We measured the total anthocyanin content closest to the fresh cornelian cherry with 2.62 and 2.11 mg (CDE) g (dw) at 70 °C and 300 W. Also, we found the closest vitamin C to the fresh ones with values of 25.02 and 20.08 mg 100 g (fw) at 300 and 500 W. Generally, the suitable drying technique in terms of physical parameters and phytochemical compounds was the microwave drying at 300 W.
即自然干燥、微波干燥、对流干燥和联合干燥。欧洲酸樱桃的水分含量从72.56%降至10.27%。在50°C、70°C、90°C以及100瓦和300瓦功率条件下测量了与新鲜样品最接近的颜色参数。新鲜和干燥的欧洲酸樱桃均具有较高的抗氧化能力，且含有多种多酚类化合物。TEAC是测定欧洲酸樱桃总抗氧化能力最合适的方法。我们在70°C和300瓦功率条件下测得与新鲜欧洲酸樱桃最接近的总花青素含量为2.62和2.11毫克（矢车菊素-3-葡萄糖苷）/克（干重）。此外，我们发现在300瓦和500瓦功率条件下与新鲜欧洲酸樱桃最接近的维生素C含量分别为25.02和20.08毫克/100克（鲜重）。总体而言，就物理参数和植物化学化合物而言，合适的干燥技术是300瓦的微波干燥。
