  • The skin whitening effects of pine needle extract, hop extract and chestnut inner shell extract were evaluated both in vitro and in B 16 mouse melanoma cell lines. Each extracts significantly inhibited tyrosinase activity, dopa auto-oxidation and melanin biosynthesis in vitro and in B 16 cell lines. In vitro, hop extract inhibited melanin biosynthesis 15 times stronger than kojic acid at $10{\;}\mu\textrm{g}/ml$ concentration. Each extracts were stronger inhibitors of melanin biosynthesis than kojic acid in B 16 mouse melanoma cell at less than $4{\;}\mu\textrm{g}/ml$ concentration. These results show that extracts fo pine needle, hop and chestnut inner shell could be developed as skin whitening component of cosmetics.

  • This research was carried out to find the dyeabilities and mordants effects of cow leather dyed with Lac powder. They were examined by changing dye concentration, dyeing temperature, bath ratio, dyeing time, and dyeing repetition. And K/S values and surface color changes were evaluated by various mordanting conditions. The optimum dyeing conditions of the cow leather dyed with Lac powder were 30%, $40^{\circ}C$, 30:1, 30minutes, and 4 repetitions. The K/S values were higher in post mordant than pre mordanting condition. The surface colors of dyed cow leathers were R and RP. The dye fastnesses increased in post Cu and Fe mordanting, as decreased in gallnut and chestnut's skin conditions.

  • This study investigated the influence of incorporating chestnut inner shell powder (CISP) at varying levels (0%, 3%, 6%, 9%, and 12% w/w) on the quality, antioxidant potential, and consumer preference of garaetteok, a Korean rice cake. Findings revealed a decrease in moisture content and pH with increasing CISP content. Color analysis indicated a reduction in lightness (L) and yellowness (b) values, while redness (a) values increased. Textural properties displayed an increase in hardness, chewiness, and gumminess, but a decrease in springiness, adhesiveness, and cohesiveness with increasing CISP levels. Sensory evaluation for appearance, taste, flavor, texture, and overall preference revealed the sample containing 6% CISP to be the most favorable. Moreover, the antioxidant activity of the garaetteok exhibited a positive correlation with increasing CISP content. In conclusion, incorporating 6% CISP resulted in improved quality characteristics for garaetteok development, offering enhanced nutritional value, antioxidant properties, and overall consumer preference.

  • 본 연구는 항산화성이 우수하나 버려지는 율피의 이용 증대를 위해 숙성시켜 파우더로 만든 후 쿠키에 첨가(0.25%, 0.5%, 1%)하여 품질 특성 및 항산화성을 분석하였다. 숙성 흑율피 첨가 쿠키의 수분 함량은 숙성 흑율피의 첨가량이 증가할수록 수분 함량도 같이 증가하였다. 가용성 고형물 함량과 환원당 함량은 숙성 흑율피의 첨가량이 증가할수록 높아졌다. 명도는 숙성 흑율피 첨가량이 증가할수록 낮아지는 경향을 보였으며, 적색도는 숙성 흑율피 첨가량에 따라 증가하였다. 황색도는 숙성 흑율피 첨가량에 따라 낮아지는 경향을 보였다. pH는 숙성 흑율피의 첨가량이 증가할수록 낮아졌으며 산도는 높아지는 경향을 보였다. 숙성 흑율피 쿠키의 조직감은 강도에서만 각각에 유의적이 차이를 보였으며 씹힘성에서는 유의적 차이를 보이지 않았다. 총페놀의 함량은 숙성 흑율피의 첨가량이 증가함에 따라 증가하였다. DPPH 라디칼 및 hydroxyl 라디칼 소거능은 숙성 흑율피 첨가량이 증가할수록 $IC_{50}$ 값이 낮게 나타나 항산화능이 증가하였다. 관능검사 결과 색상, 거침성, 숙성 흑율피의 이질성, 숙성 흑율피의 향, 숙성 흑율피의 맛은 숙성 흑율피의 첨가량이 증가할수록 높은 점수를 받았으며, 버터향과 단맛은 숙성 흑율피의 첨가량이 많을수록 낮게 나타났다. 기호도 특성 결과 전체적인 기호도와 구매의향은 0.5%의 숙성 흑율피를 첨가하였을 때 가장 높게 나왔다. 이상의 결과로부터 숙성 흑율피를 쿠키에 첨가 시 0.5% 수준으로 첨가하는 것이 바람직한 것으로 생각되며, 폐기하던 율피의 이용도를 증대할 수 있는 바람직한 방법이라 생각한다.

  • Obesity occurred by energy imbalance, is increasing regardless of race, sex, age, and related to the metabolic syndrome, diabetes and cardiovascular disease. Since adipose tissue plays a critical role in regulating energy homeostasis, understanding of adipogenesis pathway and finding of regulatory mechanism for adipogenesis can be helpful to manage obesity as well as obesity-related diseases. In this study, to investigate the effects of Chestnut Inner Shell(CIS) extract on the adipogenesis in 3T3-L1 preadipocytes, 3T3-L1 preadipocytes were differentiated with adipogenic reagents for 9 days in the absence or presence of CIS extract ranging from 10 - 100 ${\mu}g/m{\ell}$. The effect of CIS extract on 3T3-L1 differentiation was examined by measuring intracelluar lipid droplet and triglyceride contents. CIS extract remarkably inhibited lipid accumulation(about 45% inhibition at 100 ${\mu}g/m{\ell}$ of CIS extract) and slightly decreased triglyceride contents(about 15% decrease at 100 ${\mu}g/m{\ell}$ of CIS extract) in 3T3-L1 preadipocytes at the concentration showing no cytotoxicity. These results demonstrated that CIS extract significantly inhibit adipogenesis and can be used for the regulation of obesity.

  • This study was conducted to investigate the effect of chestnut inner shell powder on antioxidant activity and the quality characteristics of cookies. Cookies were prepared with different amounts of chestnut inner shell powder(in ratios of 0, 0.5, 1, 3 and 5% to the flour quantity). The antioxidant activity was estimated by DPPH free radical scavenging activity and the total phenol content in chestnut inner shell powder and cookies. For analyzing quality characteristics, bulk density and pH of the dough, spread factor, loss rate, leavening rate, color, texture profile analysis, and sensory evaluations were measured. The spread ratio, a values, total phenol contents and DPPH free radical scavenging activity of cookies significantly increased with increasing chestnut inner shell powder(p<0.001), while the pH of the dough, L values and b values of the cookies significantly decreased with increasing chestnut inner shell powder content(p<0.001). The consumer acceptability score for the 3% chestnut inner shell cookie groups ranked significantly higher(p<0.01) than those of the other groups in overall preference, flavor, taste and color. From these results, we suggest that chestnut inner shell is a good ingredient for increasing the consumer acceptability and the functionality of cookies.

  • Objectives : Cleanser is the most basic tools used in daily skin care. I made a cold process soap using Castanea crenata inner shell (CCIS). I'd like to study the effect of face wash using CCIS cold process (CP) soap on the skin. Methods : The same water and towel were used at the same place in order to examine the skin change state immediately before and after washing face. The skin test was performed before and after 10 minutes washing the face in order to remove these external environmental factors, such as lifestyle, alcohol, tobacco, and stress etc. As a control group, the cases of washing with water and foam cleanser (F/C), which is a popular commercial product, were set. Three cases were compared and analyzed. Results : In the case of water washing, there was a significant decrease in oil (U-zone) but that was not good effect. In the case of F/C and CCIS washing, there were significant decrease in oil (T-zone), pores and pigmentation, but the significance was bigger in CCIS washing. In the case of pores, there was a significant decrease in all three cases. Conclusion : In the case of F/C and CCIS washing, it showed the effect of reducing T-zone oil, pores and pigmentation. But the significance was greater in CCIS case than in F/C case. CCIS cp soap is considered as a form of face wash that is suitable for skin care.

  • Objectives : The purpose of this research was to find out the efficacy of Castanea crenata Inner Shell (CCIS) on the skin by comparing the difference effect between only MTS (microneedle therapy system) and the CCIS essence application after MTS treatment. Methods : The present author performed once a week and total 3 times of MTS treatment. The treatment time took about 5 ~ 10 minutes and the depth of the needle was adjusted according to the participant's skin condition. In the control group, essence base was applied after MTS and in the experimental group, CCIS powder dissolved essence was applied. One week after each treatment, the change of skin condition was measured. Two weeks after the end of the clinical trial, the skin condition was checked again. Results : In the case of the test group and the control group, there was a significant decrease in thermography temperature and there was a significant increase in skin tone. In the case of pores and pigmentation, there was no significant difference on both group. In the case of moisture, there was a significant increase only in the test group. Conclusion : The MTS treatment itself showed good effects on thermography temperature and skin tone. But in the case of the moisture effect, it was much better when the CCIS essence was applied to the skin after MTS treatment. This study suggests that CCIS essence increases the efficacy of MTS on the point of moisture.
