Effects of Gamma Irradiation on the Extraction Yield and Whitening Activity of Polysaccharides from Undaria pinnatifida Sporophyll

The objective of this study was to evaluate the anti-melanogenic effects of Hizikia fusiforme (HF) fractions in α-melanocyte stimulating hormone-induced B16F10 mouse melanoma cells. Ethanol extractions of Hizikia fusiforme (EEHF) were subjected to fraction by using dichloromethane (CFHF), ethyl acetate (EAFHF), butanol (BFHF), and water (WFHF). EEHF, CFHF, and EAFHF inhibited tyrosinase activity and melanin synthesis in B16F10 mouse melanoma cells in a dose-dependent manner. The melanin contents were inhibited by 40.5% and 33.2% in response to treatment with 50 μg/ml of EEHF and CFHF, respectively. In addition, tyrosinase activities showed a 53.3% and 54.1% reduction in treatment with 50 μg/ml of EEHF and CFHF. Western blotting analysis showed that EEHF, CFHF, and EAFHF inhibited tyrosinase, TRP-1, TRP-2, and MITF expression in a dose-dependent manner. In conclusion, these findings indicate that ethanol and dichloromethane fractions of Hizikia fusiforme, which inhibit melanin synthesis and tyrosinase activity, are effective skin-whitening agents.Key words : Hizikia fusiforme, melanogenesis, tyrosinase *Corresponding author *Tel : +82-51-890-1594, Fax : +82-51-890-2646 *E-mail : hhj2001@deu.ac.kr This is an Open-Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/3.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

In this study we assessed the effects of gamma irradiation (50 kGy) on cookies to which was added various concentrations (1%, 3%, 5%, 7%) of hot water extract from seamustad (Undaria pinnatifida) sporophylls (WEUS) for future industry use. The pH of the dough went down significantly with the addition of WEUS. However, density was not related to that. The spread ratio of the cookies increased significantly as more WEUS was added to the cookie recipe, and cookies containing gamma-irradiated extract were taller than non-irradiated cookies with the same concentration. The loss rate of cookies was the same between control and experiment groups. On the other hand, the leavening rate significantly increased upon the addition of WEUS, and gamma-irradiated cookies were higher than non-irradiated cookies in the same concentration. The L value of cookies was much reduced with higher WEUS content, but the b value showed no significant differences between the control and experiment groups. The a value showed no significant difference for non-irradiated groups, but did for gamma-irradiated groups. Upon the addition of WEUS, hardness was shown to be higher than the control. The antioxidant activity, DPPH radical scavenging, was significantly higher with the control cookies, and upon the addition of WEUS, the gamma-irradiated cookies had higher antioxidant effects than non-irradiated cookies. The sensory evaluation showed that cookies made with WEUS have a positive impact in color, smell, taste, texture, and overall acceptability, but the sensory evaluation worsened with a lot of WEUS. The results of acceptability were higher in cookies with 3% the non-irradiated group and 1% the gamma-irradiated group. These results suggest that the 1% gamma-irradiated group was in the best condition to use in the industry since just a little of it makes exceptional quality, sensory properties, and functionality.
