        Fermented halla gold kiwifruit (FHK) was prepared with Lactobacillus plantarum CK10, a bacterium derived from kimchi. We investigated the quality characteristics and antioxidative activity of madeleine added with FHK. The madeleine dough was prepared by mixing flour, sugar, baking powder, and then followed by adding salt, rum, different amount of the FHK (0, 1, and 3%) and butter. The total titratable acidity of madeleine increased significantly with the amounts of added FHK (p<0.05), while the pH value and total soluble solids showed the reverse trend. The color of madeleine became substantially redder with increasing amounts of FHK (p<0.05), and it appeared darker and less yellow at the same time. The total polyphenol contents of madeleines increased significantly with increasing amounts of FHK (p<0.05), but there was little difference in the total flavonoid content. When the antioxidant activities were measured in terms of 2,2-diphenyl-1-picrylhydrazyl (DPPH)- and 2,2’-azino-bis-3-ethylbenzothiazoline- 6-sulfonic acid-diammonium salt (ABTS)- radical scavenging, both measured activities of madeleines increased dramatically with added FHK in a dose-dependent manner. Our results suggested that the acidity, color, polyphenol content, and antioxidant activities of madeleines can be improved by adding the fermented gold kiwifruit.

        In this study, antioxidant activities and physicochemical properties of chocolate fermented with Lactobacillus plantarum CK10 were investigated. The pH level decreased from 5.26±0.02 to 3.98±0.06 during fermentation while titratable acidity increased from 5.36±0.19 to 13.31±0.34. The total polyphenol and flavonoid contents slightly increased during fermentation, but it was numerically negligible. Slight increase and decrease in the radical scavenging activities of chocolate, against DPPH-, ABTS-, and alkyl- radical, were observed during 32 hr of fermentation, but the changes were not statistically relevant. Composition ratios (% area by GC analysis) of lactic acid, xanthosine, and theobromine increased with fermentation time while hydroxymethylfurfural (HMF) and caffeine decreased after 32 hr of fermentation, in the order of xanthine (22.7%), theobrome (20.0%), lactic acid (14.9%), HMF (9.1%) and caffeine (9.0%). However, there was no remarkable changes in theobromine and caffeine contents in chocolate during fermentation.
