Four different spices (herbs) including rosemary, oregano, basil & sage and green tea were added individually to the ground pork or ground chicken with different percentages of 0.5, 1.0, and 1.5, respectively. The consumer sensory qualities of the five natural herbs and their antioxidant effects were evaluated using pork- and chicken-Yukwonjeon. In our consumer sensory evaluation, the 0.5% herb addition and control groups had generally better acceptability than the higher addition groups. In particular, pork-Yukwonjeon with the addition of 0.5% of green tea or oregano and chicken-Yukwonjeon with the addition of 0.5% of green tea or rosemary 0.5% were generally preferred more profoundly on the acceptance and ranking tests. However, sensory differences, especially in texture, among the different samples were reduced after storage. With regard to the results of lipid oxidation without storage, the TBARS values of the herb addition groups were slightly lower than those of the control group, but not significantly so (p>0.05). The antioxidant effects of each herb achieved higher values at longer storage times and with higher levels of added herbs. The antioxidant effects differed with different kinds of meat. The addition of the herb samples resulted in TBARS value reductions of $15.0{\sim}45.8%$ and $9.5{\sim}31.0%$, respectively, in the pork and chicken-Yukwonjeon stored at $6^{\circ}C$. Furthermore, the antioxidant effects of herbs during storage at $-20^{\circ}C$ were observed as reducing in the TBARS values of $8.4{\sim}31.7%$ and $19.0{\sim}33.0%$ in the pork-and chicken-Yukwonjeon, respectively. Green tea evidenced the highest levels of antioxidant activity on lipid oxidation, as it was acceptable even at higher concentrations according to our sensory evaluations. These results illustrate the possibility of producing superior Yukwongen with green tea and herbs, according to the different kinds of meat used.

The purpose of this study was to develop value-added seasoning products with Korean advanced chile peppers (Capsicum annuum L.) and investigate their physicochemical characteristics based on sensory evaluation. Ninety-seven chile pepper-related products were collected from American local favorites and analyzed based on their compositions. Yeongyang's chile pepper powders were prepared to develop Korean chile pepper seasoning products and measured for total microbial content (3.36 log CFU/g), moisture content (12.43%), total carotenoids (223.46 mg/100 g), vitamin C (290.33 mg/100 g), ASTA color value (149.37), and capsaicinoids (4.06 mg/100 g). Korean chile pepper seasoning samples for beef showed higher overall acceptability compared to American local favorite seasonings. Completed Korean chile pepper seasoning products contained red pepper (20%), various herbs (26.1%), salt (11.4%), dried mushroom (8.5%), garlic (8.5%), black pepper, curry, paprika, sweet pumpkin (5.7%), and citron (2.8%). This result might show the possibility of replacing mixed seasoning products from foreign countries (USA and Europe).

This study was carried out to investigate the effect of Origanum vulgare extracts on cell proliferation of human hair dermal papilla cell (HHDPC) using sulforhodamine B (SRB) assay, antioxidant activity by 1,1-diphenyl-2-picryl hydrazyl (DPPH) method, expression of insulin-like growth factor-1 (IGF-1) by analyzing reverse transcriptase polymerase chain reaction (RT-PCR) and hair growth in a shaving animal model of C57BL/6 mice topically applying with an amount of 0.1 mL once a day for 3 weeks. The mice were divided into 4 groups including normal group (saline, N), negative control group (dimethyl sulfoxide, NC), positive control group (5 mg/mL minoxidil, PC), and experimental group (Origanum vulgare extracts, OV). Treatment of OV didn't show cytotoxicity in HHDPC up to 10 ${\mu}g/mL$ and exhibited antioxidant activity with $IC_{50}$ of 31.0 ${\mu}g/mL$. IGF-1 expression in the skin was significantly (p<0.05) increased in the PC and OV compared to the N or NC. PC and OV also showed a prominently promoted hair regrowth compared to the N or NC in hair growth observation. The hair regrowth of OV was significantly higher than that of PC (p<0.05). Therefore, these results indicate that O. vulgare extracts effectively stimulated hair growth in an animal model.

This study aimed to determine the physicochemical, microbiological, and sensory qualityies of steamed chicken samples by prepared with combined additions of oregano-allspice and Ascorbic acid (OA/AA), and processed by a sous-vide cook - chill system. The hurdle effect of the OA/AA addition was examined in terms of microbial stability improvements and their effects on sensory were also evaluated. First, the microbial risk was lowered and chicken quality was good with the addition of the OA/AA hurdle as compared to the control. Second, over various days of storage, the microbial quality of the OA/AA samples was relatively high. In standard plate counts, the control group presented a bacteria level of 2.75 LogCFU/g at 10 days of storage, but the OA/AA groups were had counts of 2.38, 1.89 and 1.81 LogCFU/g, respectively. And at 15 days of storage, the control group had a level of 3.65 LogCFU/g whereas the OA/AA groups had counts of 3.55, 3.54, and 3.24 LogCFU/g, respectively. Lastly, the sensory scores of the OA/AA groups were higher than those of the control group. Accordingly, overall microbial and sensory characteristics were better in the OA/AA hurdle groupsf than in the control group. Thus, the combined addition of Oregano-allspice and Ascorbic acid may be and alternative means for extending shelf - life.

Skin wrinkles typically appear as a result of aging processes. One of causes may be the nonenzymatic glycation followed formation of browning products called advanced glycation endproducts (AGEs), an irreversible cross-linked protein. The accumulation of glycated collagen cross-linked in skin inhibits the formation and function of skin tightening agents such as collagen and elastin. To development for anti-wrinkle ingredients from edible plants, MeOH and hot-water extracts were prepared and evaluated for their inhibitory effects of AGEs formation. The activities of both extracts from bay laurel (Laurus nobilis), cinnamon (Cinnamomum loureirii), clove (Eugenia caryophyllate), oregano (Origanum vulgare), rosemary (Rosemarinus officinalis), savory (Satureja hortensis) and star anis (Illicium verum) of western spices, and blackberry (Rubus coreanus), dayflower (Commelina communis), Epimedium koreamun (whole), termunalia frutus (Terminalia chebula) and turkestan rose (Rosa rugosa) of medicinal plants were higher than the others. Of Korean vegetables, however, MeOH and hot-water extract from only Asters caber and green tea showed higher activities, and no activity in Korean marine plants (seaweeds).

The aim of this study is to investigate the effects of rosemary on the quality characteristics of tomato sauce during storage period(60days). As storage time went by, analysis of color differences of tomato sauce showed that "L", "a", "b"-value of tomato sauce less decreased with more herbs added, but there were no significant differences. As storage time went by, the pH ranged between 4.10-4.25, the sweetness between $10.50-9.67^{\circ}Brix$, and the salinity between 0.90~1.56 among all additions. Also, the more herbs were added, the more viscosity increased. The reducing sugar content ranged between 38.87-55.38, and its highest was shown in the sample with 0% of rosemary during the storage period. The sensory evaluation was performed with scoring tests for color, flavor, taste, aftertaste, viscosity, and overall acceptability by 15 professional panelists. The result showed that the tomato sauce with 1% rosemary was the best in the color, flavor, taste, aftertaste, and overall acceptability. From the above results, the study suggests that the addition of 1% fresh rosemary to tomato sauce is recommended for commercial use.

The selenium (Se) contents of 20 herbs, harvested in three areas in Korea, were analyzed. Many herbs had no Se. Angelica ($138.4{\mu}g \;Se{\cdot}kg^{-1}$ FW), caraway ($167.8{\mu}g \;Se{\cdot}kg^{-1}$ FW), chamomile ($116.6{\mu}g \;Se{\cdot}kg^{-1}$ FW), marjoram (158.7 and $132.6{\mu}g\;Se{\cdot}kg^{-1}$ FW), and oregano ($62.5{\mu}g\;Se{\cdot}kg^{-1}$ FW) accumulated Se as higher concentration compared with other plants. The Se content of herbs was dependent on the species, cultivars and areas. The status of Se uptake by herbs was investigated according to Se concentrations in hydroponics. During four weeks, before harvest of several herbs in greenhouse, sodium selenate ($Na_2SeO_4$) was added to the nutrient solution at concentrations of 2, 4, 6, and $8mg{\cdot}L^{-1}$. Field-mint accumulated Se too high, but external symptom of Se toxicity was not found. Essential oil content was generally proportionated to treated-Se concentration. The essential oil contents in basil and balm increased two to three times higher by sodium selenate treatment compared to non-treatment, but they did not show any linear relationship between essential oil contents and treated-Se concentration.

Four different herbs, including rosemary, oregano, basil and sage, along with green tea were individually added to ground beef at different percentages: 0.5, 1.0, and 1.5, respectively. The sensory qualities of the five natural herbs and their antioxidant effects were evaluated using Beef-Yukwonjeon. For the sensory evaluation results, the 0.5% herb addition and the control group generally showed higher acceptability scores than the 1.0% or 1.5% herb addition groups. In particular, the Yukwonjeon made with 0.5% green tea showed higher preferences in the acceptance tests and ranking tests. However, the sensory differences among samples were reduced after 3 days of storage at $6^{\circ}C$. For the results of lipid oxidation without storage, the TBARS values of the herb addition groups were slightly lower than the value of the control group, but not significantly(p>0.05). However, the antioxidant effects of each herb showed higher values over a longer storage period as well as at the higher herb concentrations. The antioxidant effects of the herbs during 7 days' of storage at $6^{\circ}C$ were evaluated as $10.0{\sim}38.5%$ reductions in TBARS values as compared to the group without herbs. Furthermore, the antioxidant effects of the herbs during 30 days' of storage at $-20^{\circ}C$ were shown as $16.8{\sim}27.8%$ reductions in the TBARS value. The green tea showed the highest antioxidant activity against lipid oxidation, because it was acceptable at higher concentrations in the sensory evaluation. These results indicate the potential to produce better quality beef-Yukwonjeon, with herbs, especially green tea.
