This paper investigates the antioxidant activity and quality characteristics of yanggaeng containing white ginseng and red ginseng extracts and their enzyme hydrolysates that were produced for the purpose of the study. White and red ginseng extracts were hydrolyzed using Rapidase C80 max, Pyr-flo, and Ultimase MFC. Ginsenoside F2 and compound K (CK) were not detected in white and red ginseng before enzymic reaction but were detected in white and red ginseng hydrolyzed through Rapidase C80 max, Pyr-flo, and Ultimase MFC, and the content of CK was the highest in the second enzymic reaction group of red ginseng. Upon preparing yanggaeng containing white and red ginseng before or after enzymatic hydrolysis, the polyphenol content and antioxidant abilities were analyzed. The yanggaeng containing enzyme-hydrolyzed white ginseng and red ginseng showed greater total polyphenol content, superior DPPH radical scavenging activity, superior ABTS radical scavenging activity, and superior FRAP analysis results compared to the yanggaeng that doesn’t contain white or red ginseng. As the enzymic reaction was performed in the added white and red ginseng, the antioxidant activity increased significantly (P<0.05). In brightness( L*), non-additive yanggaeng (control group) was the highest, red ginseng yanggaeng (RG) showed the highest redness(a*), and the white ginseng yanggaeng (WG) showed the highest yellowness(b*). In terms of texture, the yanggaeng containing red ginseng with second hydrolysis (RG-T2) showed significantly high results in hardness, springiness, chewiness, cohesiveness, and gumminess (P<0.05). In conclusion, treating white and red ginseng with Rapidase C80 max, Pyr-flo, and Ultimase MFC is very useful in ginsenoside deglycosylation and will produce CK with excellent biological activity. It can also be seen that yanggaeng containing white and red ginseng hydrolyzed with enzymes significantly increase total polyphenol and antioxidant activity compared to the control group (yanggaeng with no added ginseng). These results will be useful as excellent foundational data for the production of functional yanggaeng in the future.
