Abstract

This study was carried out to investigate the changes in the antioxidant activity of Cheonggukjang with the addition of hazelnut. The number of Bacillus subtilis and the content of crude fat were increased with the addition of hazelnut. The addition of hazelnut made the color of Cheonggukjang lighter. The flavonoid and polyphenol content were sharply increased in proportion to the addition of hazelnut. The DPPH radical scavenging activity of Cheonggukjang was also increased with the addition of hazelnut. Taken together, it was found that the addition of hazelnut had a positive influence on Cheonggukjang by increasing the antioxidant activity.
