The purpose of this study is to analyze the growth characteristics of native Kentucky bluegrass (Poa pratensis L.) collected in Korea. Out of Kentucky bluegrasses collected in 2000 and 2008, eight ecotypes ("Pyengchang," "Gongju," "Inje," "Donggang," "Hwasun," "Pureundle," "Cheongsong," and "Geumsan") were planted in experimental fields and pots on May 11, 2008 and May 3, 2009, respectively, for analyzing their growth characteristics. Data such as visual quality (1-9), visual density (1-9), visual color (1-9), plant height, leaf length and leaf width were analyzed. The visual quality of "Pyengchang," "Inje" and "Gongju" were enhanced compared to the rest native ecotypes of Kentucky bluegrass. "Pyengchang" showed the best visual density while "Gongju" and "Inje" showed almost evenly favorable density. However, "Pureundle," "Cheongsong," and "Geumsan" represented loose density due to the damage from the summer climate of high temperature and humidity in 2009. As for visual color, "Pyengchang" was also ranked first, maintaining high values of at least 7.6 even in the summer climate of high temperature and humidity. "Donggang" showed good color immediately after planting in the experimental field in 2008, however, undesirable color due to the damage from the summer climate of high temperature and humidity in 2009.

This study investigates the current status and dyeing properties of various natural indigo powder dyes in the domestic market. Products from India, China, Europe are sold in the market and only a few manufacturers provide recommendation for the method of dyeing and information on the additives. Through the market research and the preliminary investigation on 21 products, 11 were selected for the dyeing experiment which include 3 Indian, 3 Chinese, 2 German, and 1 Pakistani origin indigo reduced powders, and 2 Indian origin dried indigo leaf powder. The two dyeing methods used were the precipitation method and the fresh juice method, both at $10^{\circ}C$, $25^{\circ}C$, and $60^{\circ}C$. Color difference, K/S value, and colorfastness of dyed cotton fabrics were examined. Indian reduced indigo powder showed the highest K/S value, deep dyeing, and the best color fastness. Chinese reduced indigo powder resulted in a more greenish and bluish color. Powders of dried indigo leaves were easy to use but resulted in a pale color due to low dye uptake.

본 연구에서는 기능성 식품 소재인 모시 잎 분말을 손쉽게 다식으로 제조할 수 있는 볶은 콩가루에 첨가하여 모시 잎 분말 콩다식을 제조한 후 품질특성을 살펴보았다. 모시 잎 분말 0% 콩다식의 경우 수분함량은 $8.39{\pm}0.98%$로 가장 적게 나타났으며 모시 잎 분말 10% 첨가한 콩다식의 경우가 $14.71{\pm}0.02%$로 가장 높게 나타났다. 모시 잎 분말 콩다식의 명도와 적색도, 황색도는 모시 잎 첨가량이 증가함에 따라 유의적으로 감소하는 경향을 보였다(p<0.05). 모시 잎 분말 콩다식의 조직감 측정 항목 중 경도, 검성, 씹힘성의 경우 모시 잎 분말 첨가량에 따라 유의적으로 증가하는 경향을 보인 반면 부착성과 응집성은 유의적으로 감소하는 경향을 보였다(p<0.05). 모시 잎 분말 콩다식의 관능검사 색과 맛, 부드러운 정도, 전체적인 기호도의 경우 모시 잎 분말 8% 콩다식이 가장 높게 평가되었고 향기는 모시 잎 분말 첨가량에 따라 유의적으로 차이를 보이지 않았다. 따라서 모시 잎 분말을 첨가한 콩다식의 경우 색이나 맛, 향기, 전체적인 기호도에 있어서 8%를 첨가하는 경우가 가장 바람직한 첨가 수분이라고 사료된다.

The purpose of this study was to investigate the rheological characteristics of medium wheat flour mixed with bamboo leaf and lotus leaf powders. Rheological properties of the mixed flours were tested based on falling number, color, RVA, farinogram, and rheofermentometer analyses. Falling numbers increased with addition of bamboo leaf and lotus leaf powders. The L values of all mixed flours were less than that of control. The 1% mixed flour sample containing bamboo leaf and lotus leaf powders was not significantly different from 3% mixed flour. The a values of the mixed flour decreased as bamboo and lotus powders increased, whereas b values increased. Addition of bamboo leaf and lotus leaf powders to flour reduced peak viscosity, holding strength, and final viscosity. The set back values of mixed wheat flour containing bamboo leaf powder were lower than those of mixed wheat flour containing lotus leaf powder, suggesting that bamboo leaf powder suppressed retrogradation of flour compared to lotus leaf powder. In the farinogram, the water absorption and consistency of the flours containing bamboo and lotus leaf powders increased, whereas development time and stability decreased. The fermentation time of dough with lotus leaf powder was less than that of dough with bamboo leaf powder.

We investigated the quality characteristics and volatile flavor components in yenipsambab prepared with various concentrations of lotus leaf powder. Hunter's color L and a values of yenipsambab decreased with increasing content of lotus leaf powder, whereas b value increased. Moreover, addition of lotus leaf powder resulted in increased hardness, adhesiveness, chewiness, and brittleness compared to control. Major volatile compounds of yenipsambab were ethyl benzene, 1,3-dimethylbenzene, 1,2-dimethylbenzene, and 5-hydroxymethyldihydrofuran-2-one.

This study was carried out to investigate the effect of different soil moisture contents on the growth and chemical constituents of burley tobacco and on the protein pattern in tobacco leaf. Height, stem diameter, and largest leaf length of tobacco droughted from 45 to 60 days after transplanting was not recovered by rewatered amount of water supply from 60 to 75 days after transplanting, but leaf width enlarged. Dry weight per unit leaf area and total nitrogen content showed high values in low soil moisture, but total alkaloid contents were not different according to soil moisture contents. Soil moisture content didn't effect on the protein pattern of middle and upper leaves, but lower leaves showed the mild color and fewer numbers of the protein bands than those of midd1e and upper leaves.

본 연구는 항산화능이 우수한 음나무 잎을 쌀쿠키에 첨가하여 대조군과 실험군 간 항산화 활성과 품질 특성을 비교 분석하였다. 음나무 잎의 총 페놀 함량은 50.74 mg GAE/g, DPPH radical 소거활성 $IC_{50}$은 $41.09{\mu}g/mL$, 환원력은 1 mg/mL의 농도에서 흡광도 1.55로 음나무 잎의 우수한 항산화능을 확인할 수 있었다. 쌀쿠키의 경우, 음나무잎 분말의 첨가량이 증가할수록 수분함량, 퍼짐성, 팽창률, 색도 b값은 증가하는 경향을 나타내었다. 쌀쿠키의 항산화 활성 물질인 총 페놀 함량을 정량한 결과, 음나무 잎 첨가량이 증가할수록 페놀함량이 증가하는 경향을 보였으며, 쌀쿠키의 DPPH radical 소거능, 환원력 측정 결과, 음나무 잎 분말의 첨가량이 증가할수록 항산화능이 증가하는 경향을 보였다. 관능검사 결과에서는 음나무 잎 분말을 3% 첨가한 쌀쿠키가 가장 높은 점수를 받았으며, 5% 이상 첨가 시는 전반적인 기호도가 감소하는 것으로 나타났다. 이상의 결과를 종합하여 볼 때 음나무 잎 분말을 첨가한 쌀쿠키는 대조군에 비해 우수한 항산화 활성을 보였으며, 관능적으로도 우수한 것으로 평가되었다. 따라서 기능성과 기호도 측면을 모두 고려하였을 때 쌀쿠키에 3% 음나무 잎 분말 첨가는 기능성과 기호성을 갖춘 식품으로서 적합하다고 판단된다.

In this study, we assessed the antioxidant activities and quality characteristics of cookies containing various concentrations (0, 1, 3 and 5%) of Eleutherococcus sessiliflorus leaf powder. Antioxidant activity was estimated based on DPPH free radical scavenging activity and total content of phenolic compounds in Eleutherococcus sessiliflorus leaf powder and cookies. The quality characteristics of Eleutherococcus sessiliflorus leaf cookies were estimated based on spread factor, loss rate, leavening rate, color, texture and sensory evaluation, polyphenol contents, DPPH free radical scavenging activity, as well as spread factor of cookies significantly increased. L value, b value and hardness of cookies decreased with increasing Eleutherococcus sessiliflorus leaf powder content. Finally, the sensory evaluation showed the highest scores for cookies containing 3% Eleutherococcus sessiliflorus leaf powder. From these results, we suggest that Eleutherococcus sessiliflorus leaf is a good ingredient for increasing consumer acceptability as well as the functionality of cookies.

This study was conducted in order to promote the utilization of Hovenia dulcis Thunb as food. The physicochemical properties and sensory characteristics of the extracts from the leaf, fruit, stalk and stem were examined. The extract of stem was the brightest in L value (p<0.05), but the lowest in b value (p<0.01). By the sensory evaluation, the external appearance was the best in the extract of stem. The extract of leaf was the darkest in color and that of stem the lightest. The bitter and astringent taste was stronger from the leaf compared with other parts. The extract of fruits stalk of Korean Hovenia dulcis was preferred in most of attributes. The total sugar content was the highest from the fruits stalk. Among free amino acids, aspartic acid, glutamic acid and alanine were rich in order. Potassium contents were the highest among minerals from the fruits stalk, leaf and stem. Ca and Mg followed the next. The results were the same both in Korean and in Chinese tree. Among organic acids, malic acid was the most in the fruits stalk, leaf and stem. It was followed by citric acid. In the test of free sugar, glucose was the most and followed by sucrose and fructose in the fruits stalk. Fructose was contained the most in leaf and stem.
