Abstract
Objectives : To further enhance the business value of domestic Schisandrae Fructus, new products composed of modified Gyeongok-go were developed. Their preferences and antioxidant behaviors were compared under different manufacturing processes. Methods : Sensory evaluation was carried out on a 7-point scale by a taste panel. Additionally, the antioxidant activities were investigated in vitro against ABTS[2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid)] and DPPH(2,2-diphenyl-1-picrylhydrazyl). Results : The differences among each sample were not statistically significant in sensory evaluation. In contrast, the antioxidant properties of each sample can have up to twice effect distinction at a final concentration of 2.5 mg/ml. Conclusions : Manufacturing methods, while having smaller effect on sensory evaluation, greatly affected the antioxidant properties. As a consequence, the optimum manufacture conditions need to be established using different manufacture conditions and activity search methods.
