Whitening is inhibitory activity of the melanin synthesis of melanocytes. Recently, whitening materials have been developed on natural materials because of its side effects on skin. Figs (Ficus Carica L.) is a fruit belonging to the Moraceae family and whitening activity was reported in focusing on the fig's stem and leaf components, but whitening activity of the figs fruit was not known. Thus, in this study, we tried to observe its anti-melanogenesis as well as antioxidant and anti-inflammation. The radical scavenging activity of figs fruits extract (FFE) was observed as the level of 34.52±1.98%/60.71±1.26% compared to the control in the its maximum concentration in the DPPH/ABTS assay. Cytotoxicity of FFE was observed at 10% concentration by CCK-8 assay, so the maximum concentration was set at 5% and applied to all experiments. FFE concentration dependently decreased NO production associated with inducible nitric oxide synthase, cyclooxygenase-2, interleukin-6 and tumor necrosis factor-α gene expression, these strongly suggesting anti-inflammatory activity.In melanin contents assay, FFE significantly down-regulated melanin production in α-MSH-stimulated B16F10 cell as well as tyrosinase inhibition in vitro. In addition, FFE decreased the Microphthalmia-associated transcription factor (MITF) mRNA expression about 94.34% compared to the α-MSH treatment group in RT-PCR. Finally, FFE significantly reduced the MITF, cAMP response element-binding protein and tyrosinase protein expression in the α-MSH stimulated B16F10 cell. Through these results, we found that FFE can not only directly inhibit tyrosinase enzyme activity but also suppress melanogenesis through regulation of MITF gene expression in α-MSH signal transduction.

This study aimed to investigate the quality characteristics of sourdough produced using a banana starter. The contents of sugar and alcohol of the banana fermented broth increased significantly as the fermentation date increased (p<0.05), and the pH tended to decrease. The titratable acidity of the fermentation broth increased significantly from the 2nd day of fermentation and remained high until the 4th day (p<0.05). The pH of dough and bread decreased as the amount of sour starter added increased (p<0.05), and there was no significant difference in titratable acidity of dough and bread as well as the amount of starter. According to the added amount of banana sour, the moisture content of the bread increased, the crude fat and crude flour content decreased, and the crude protein content hardly changed. The height of bread increased in proportion to the increase in the amount of sour starter added. As for the internal color of the bread, the brightness and yellowness decreased as the addition amount increased, and the redness increased. It was found that the volume, specific volume and baking loss rate of bread increased as the amount of sour starter added increased. In the texture of bread, elasticity and adhesion increased as the amount added increased, but gumminess, brittleness and hardness decreased as the amount added increased. From the above results, it is expected that the banana starter will be used as a useful ingredient in the development of sourdough bread products.
