Fermented garlic or also referred to as black garlic goes through heating process so that it has antioxidants activity both in vivo and in vitro. Antioxidant activity of black garlic may be affected by the processing method. Black garlic has a dark brown color and fresh sweetness, different from aroma, taste and color, as well as antioxidant potential in garlic. This study was aimed to evaluate antioxidant activity, phenolic and vitamin C content in black garlic after it undergoes drying process at temperature of 60-90°C to improve sensory quality. The method used to determine phenolic content used Folin reagents, antioxidant content with radical scavenging ability DPPH method, and vitamin C level with Iodometric titration. The phenolic content of black garlic and vitamin C at temperature of 80°C showed noticeable difference (P<0.05) with value of 21.0982 ± 0.089 mg GAE/g and 0.5632 ± 0.009 mg/g respectively. Antioxidant activity showed the highest IC50 value at 80°C warming with value of 146.2954 ± 121.849 ppm (P>0.05). It can be concluded that heating affected IC50, phenolic, and vitamin C content of black garlic.
