The purpose of this study was to investigate the preferences, consumption, and eating frequencies of housewives for commercialized traditional basic side dishes. The investigators visited 18 food markets and questionnaires were distributed to 464 housewives in the Busan area. The number of basic side dishes being sold at the markets were in the order of seasoned dried radish (17 markets; mk), salted garlic stalk (15 mk), braised black soy beans (14 mk), braised peppers and dried anchovies (13 mk), and braised lotus roots (12 mk). The housewives' order of preferences was for stir-fried dried anchovies, braised peppers and dried anchovies, braised seasoned beef, salted perilla leaf, and perilla leaf kimchi equal to seasoned sea lettuce, respectively. The order for eating frequency was stir-fried dried anchovies, braised peppers and dried anchovies, salted perilla leaf, and perilla leaf kimchi, respectively. Salted perilla leaf, perilla leaf kimchi, braised crab preserved in soy sauce, salted bean leaves, seasoned dried radish, and seasoned crab were either occasionally or frequently purchased by over 40% of the women. However, the reasons they did not purchase these products included: the excess use of chemical seasonings, unsanitary, unreliable cooking process, unreliable the origin, and high price, in the respective order. If the commercialized traditional basic side dishes were improved to eliminate these problems, 52.2% of the housewives would buy the products, and 65.6% anticipated increasing their use of these products in the future.

Screening and identification of genetic resources based on their phytoconstituents and morphological characters potentially provide baseline data for researchers, breeders, and nutraceutical companies who wish to formulate a nutrient-dense diet and health beneficial supplement. Thus, we evaluated the amount of total phenolic content and major phenolic compounds; examined if phenolic compounds could be used as distinguishing factors for perilla genetic resources; and investigated the relation between some quantitative and qualitative morphological characters with the contents of phenolic compounds in 360 accessions obtained from National Agrobiodiversity Center gene bank, Jeonju, Korea. Total phenolic content (TPC) was estimated using Folin-Ciocalteu colorimetric assay. Individual phenolic compounds were determined using an Ultra-High Performance Liquid Chromatography system equipped with Photodiode Array detector. Considerable variations were observed in TPC (7.99 to 117.47 mg GAE/g DE), rosmarinic acid (RA) (ND to 19.19 mg/g DE), caffeic acid (CA) (ND to 0.72 mg/g DE), apigenin-7-O-diglucuronide (ADG) (ND to 1.24 mg luteolin equivalent (LUE)/g DE), scutellarein-7-O-glucuronide (SG) (ND to 4.32 mg LUE/g DE), and apigenin-7-O-glucuronide (AG) (ND to 1.60 mg LUE/g DE). RA was the most dominant phenolic compound in most accessions (95.3%) followed by SG. The adaxial leaf color was light green, green and dark green in 13.8%, 65.0%, and 21.1 % of the accessions, respectively. 78.8% of the accessions had light green color at the abaxial side with the remaining being described as green. Most of the accessions (96.9%) were cordate shape, the remaining being eclipse. Intensities of green pigment at abaxial and adaxial leaf surfaces were correlated with contents of individual phenolic compounds and TPC whereas leaf length and width had no correlation with TPC, CA and RA, and negatively correlated with ADG, AG, and SG. Leaf shape was not related with content of phenolic compounds, color of leaves, or the length or width of leaves. Accessions IT57426, IT157434, IT267710, and IT267712 which contained relatively high contents of TPC and major phenolic compounds (RA and SG) could be used for further research in breeding and bioassay test. Our study result showed the contents of total phenolics and individual phenolic compounds along with the morphological characters could be useful distinguishing factors for perilla genetic resources.

Korean native Perilla Jangachi (salted and fermented vegetable) is popular and well-known but little study on its composition and most palatable condition has been reported. This study was performed to observe the change in the contents of chemical components and sensory evaluation of Perilla Jangachi which was prepared through two processing. First, as a pretreatment, Perilla leaves were soaked in salt water. The optimal level of salt concentration and soaking time (salt 4%, soaking time 42hours) was determined. Second, soaked Perilla Jangachi was steamed and then fermented in various ingredients like soy sauce, sugar, onion and so on. In this study, Perilla Jangachi was made by 3 levels of steaming time(30 seconds, 60 seconds, 90 seconds) and onion contents (10%, 30%, 50%). The optimal level of onion contents and steaming time was determined with the results of sensory evaluation by response surface methodology and analysis of composition. Sodium contents were decreased as the levels of onion contents were increased. Flavonoids contents weren't increased although contents of onion were increased. But they were influenced on steaming time that as the levels of steaming time were shortened, flavonoids contents were increased. To lengthen the shelf-life of Perilla Jangachi, the activities of enzyme peroxidase - which changes Jangachi's quality bad - by various levels of steaming time were measured. After steaming 50 seconds, peroxidase became inactive. Reducing sugar contents were decreased relying on either increased steaming time and onion contents. While steaming 30 seconds and 10% onion contents, the content of reducing sugar was 0.858% but steaming 90 seconds and 50% onion contents, it became 0.372%. Among the sensory attributes, brownness was increased as onion contents increased and steaming more than 60 seconds. Saltiness, sweetness, perilla flavor were greater relying on decreased onion contents. Toughness was decreased as both the amounts of onion and steaming time were increased. With this results, the most optimal adding level of onion content and steaming time was determined. Steaming 72 seconds and adding onion 27% was established as a optimal condition of Perilla Jangachi.

This study developed an HPLC analysis method for the determination of isoegomaketone (IK) and perillaketone (PK) in Perilla frutescens (L.) Britton leaves. P. frutescens ethanol extract was optimized through an HPLC analysis using a C18 column ($250{\times}4.6mml$, D, $S-5{\mu}m$, 12 nm) with gradient elution of water and acetonitrile as the mobile phase at a flow rate of 1 mL/min and a UV detection wavelength of 254 nm. The results of this method showed linearity in the calibration curve at a coefficient of correlation ($R^2$) of IK 0.9995, PK 0.9998. The limits of detection (LOD) for IK and PK were $0.234{\mu}g/mL$ and $0.952{\mu}g/mL$. The limits of quantification (LOQ) for IK and PK were $0.017{\mu}g/mL$ and $0.043{\mu}g/mL$. The inter-day precision RSDs of IK and PK in the P. frutescens were 1.25 to 2.69% and 0.36 to 1.10%, respectively, and the intra-day precision RSDs of IK and PK were 0.96 to 2.51% and 0.90 to 1.93%, respectively. The accuracies of IK and PK were 96.31 to 97.92% and 101.26 to 105.14%. In conclusion, this method was applied successfully to the detection of IK and PK in P. frutescens.

본 연구는 들깻잎에 존재하는 Salmonella Typhimurium, Staphylococcus aureus에 대한 전해수의 저감효과를 분석하고 전해수로의 유기물의 유입과 들깻잎과 전해수의 비율이 전해수의 효과에 미치는 영향을 분석하고자 수행하였다. 들깻잎에 S. Typhimurium과 S. aureus을 7.0 $log_{10}CFU/g$ 정도로 접종 한 후 25, 50, 75, 100 ppm에서 1, 3, 5분 동안 각각 처리하여 시간과 농도에 따른 전해수 효과를 분석하였다. 또한 유기물이 전해수의 효과에 미치는 영향을 분석하기 위해 전해수에 첨가한 유기물 농도는 150, 300, 450, 600 ${\mu}g/L$ 수준이었고, 들깻잎과 전해수의 처리비율은 1:10, 1:25, 1:50이었다. 그 결과, S. Typhimurium과 S. aureus 모두 유효 염소 농도가 증가할수록 미생물 저감효과도 높아지는 경향을 보였으며(p<0.05) 두 균주 모두 100 ppm 처리에서 25 ppm 처리에서 보다 전해수의 저감효과가 약 0.7 $log_{10}CFU/g$ 정도 높게 나타났다(p<0.05). 하지만 처리 시간에 따른 효과는 없었다(p>0.05). 또한 전해수 중 유기물 함량이 증가할수록 S. Typhimurium과 S. aureus의 제어효과는 감소하였다(p<0.05). 유기물 600 ${\mu}g/L$ 첨가시 유기물 첨가를 하지 않았을 때에 비하여 S. Typhimurium은 1.10 $log_{10}CFU/g$, S. aureus는 0.8 $log_{10}CFU/g$의 전해수 효과가 감소하였다. 들깻잎과 전해수의 처리비율은 1:10으로 처리하였을 때 미생물 저감효과는 S. Typhimurium 0.57 $log_{10}CFU/g$, S. aureus 0.79 $log_{10}CFU/g$로 전해수에 의한 미생물저감 효과를 기대하기 어려웠다. 따라서 들깻잎에서 S. Typhimurium과 S. aureus의 효과적인 제어를 위해서는 전해수 처리전에 물 세척을 통하여 흙과 먼지를 제거하고 전해수 농도 100 ppm에서 1분 이상 처리해야한다. 또한 들깻잎과 전해수 비율은 1:25 이상 유지하는 것이 바람직할 것으로 사료된다.
