  • Sixteen antioxidative active compounds isolated from the EtOAc layer of MeOH extracts of kochujang, Korean fermented red pepper paste, were structurally elucidated as fumaric acid, methyl succinate, succinic acid furan-2-yl ester methyl ester (gochujangate, a novel compound), 2-hydroxy-3-phenylpropanoic acid, 3,4-dihydroxybenzoic acid, 2,3-dihydroxybenzoic acid, 2,4-dihydroxybenzoic acid, 6,7-dihydroxy-2H-chromen-2-one (esculetin), caffeic acid, cis-p-coumaric acid, trans-p-coumaric acid, daidzin, genistin, apigenin 7-O-$\beta$-D-apiofuranosyl($1{\rightarrow}2$)-$\beta$-D-glucopyranoside, apigenin 7-O-$\beta$-Dglucopyranoside, and quercetin 3-O-$\alpha$-L-rhamnopyranoside by mass spectrometry (MS) and nuclear magnetic resonance (NMR) experiments. These compounds were analyzed for the first time as antioxidants from kochujang.

  • 본 연구는 그린커피빈추출물이 「건강기능식품의 기준 및 규격」에 추가로 등재될 경우를 대비하여 표준화된 클로로겐산 시험법을 설정하고, 카페인이 동시 분석되도록 최적화하는 연구를 진행하였다. 최적화된 시험법을 마련하기 위해 기기분석 및 전처리 조건을 비교·분석하여 클로로겐산과 카페인을 30% 메탄올 추출하여 인산용액과 인산 함유 아세토니트릴으로 액체크로마토그래프를 통해 330 nm, 280 nm에서 분석하도록 시험법을 설정하였다. 시험법 밸리데이션 결과, 직선성 정량범위 내에서 상관계수(R2) 0.999 이상의 유의수준을 보였고, 클로로겐산과 카페인 검출한계는 0.5와 0.2 ㎍/mL, 정량한계는 1.4와 0.4 ㎍/mL로 나타났다. 정밀도와 정확도 결과는 AOAC 밸리데이션 가이드라인를 통해 적합함을 확인하였고, 클로로겐산 및 카페인 동시분석법을 최종적으로 마련하였다. 또한, 시제품과 유통제품을 통해 제형별 적용성 검토하여 클로로겐산과 카페인을 동시에 정량 가능한 시험법임을 재확인하였다. 최적화된 시험법은 클로로겐산을 함유한 건강기능식품 품질관리에 대한 신뢰성을 더 높일 것으로 본다.

  • In the present report, the effects of blanching, steaming, and high temperature/high pressure processing (HTHP) on the amino acid contents of commonly consumed Korean root vegetables, leaf vegetables, and pulses were evaluated using an Automatic Amino Acid Analyzer. The total amino acid content of the samples tested was between 3.38 g/100 g dry weight (DW) and 21.32 g/100 g DW in raw vegetables and between 29.36 g/100 g DW and 30.55 g/100 g DW in raw pulses. With HTHP, we observed significant decreases in the lysine and arginine contents of vegetables and the lysine, arginine, and cysteine contents of pulses. Moreover, the amino acid contents of blanched vegetables and steamed pulses were more similar than the amino acid contents of the HTHP vegetables and HTHP pulses. Interestingly, lysine, arginine, and cysteine were more sensitive to HTHP than the other amino acids. Partial Least Squares-Discriminate Analyses were also performed to discriminate the clusters and patterns of amino acids.

  • 신선초의 기능성 해명과 유용 기능성성분 탐색연구의 일환으로 신선초 지상부로부터 항산화활성물질을 분리하여 구조 해석하였다. 신선초 지상부의 열수추출물을 용매분획하여 ethyl acetate 가용 중성획분을 얻었다. 이를 Sephadex LH-20 column chromatography와 HPLC로 정제하여 항산화활성물질 2종을 단리하고, 그들 각각의 화합물을 대상으로 FAB-MS와 NMR 분석을 실시한 결과, pseudoisopsoralen과 8-methoxypsoralen(xanthotoxin)으로 동정하였다.

  • The objective of this study was to analyze labeling improvements and evaluate willingness to pay for health functional foods with a focus on the caution for intake. For this study, we conducted a survey on health functional food intake behavior, confirmation and improvements of cautions for intake. We assessed the willingness to pay for improvement of the caution for intake. Consumers anticipate improved immune function, and fatigue improvement after consumption of health functional foods. They mainly checked the function components related to efficacy and effectiveness, ingredients and their contents, ingestion amount and method, expiry date and best mode of storage, product name, and cautions associated with ingestion of health functional foods. They has been difficulties in obtaining sufficient caution information for intake from the current labeling method. Therefore, it is necessary to improve the labeling of caution for intake. The analysis indicated that about 5.14% of the respondents were willing to pay more if new labeling was introduces. However, there is still controversy over their safety, which is damaging to the consumers. Therefore, by providing consumers with accurate and detailed information on cautions for intake, it can contribute to securing safety and improving the quality of health functional foods.

  • This study was carried out to make functional laver added with sericulture powder which have a effect of prevention adult diseases such as diabetes mellitus, hypertention, and obesity. In our lab. a lot of study have been performed about functional effect of sericulture(mulberry leaf, silkpeptide and silkworm) for examples decrease of serum cholesterol, triacylglyceride and control of serum glucose in rat. sericulture powder was prepared by pulverizing freeze-dried. Functional laver samples were prepared, and the sensory evaluation quality, physical characteristics and mineral contents of those were compared. In case of overal quality of sensory evaluation, silkpeptide powder laver was lower than other samples. The content of moisture of functional laver added with sericulture powder samples(control, sample 1, 2, 3) were 0.30, 0.98, 0.24 and 0.28%, respectively. The content of crude protein of functional laver added with sericulture powder samples were 40.50, 44.10, 56.75, and 62.50%, respectively. The content of crude fat of functional laver added with sericulture powder samples were 4.00, 4.10, 4.00 and 4.40%, respectively. The content of ash of functional Laver added with sericulture powder samples were 7.07, 7.53, 7.60 and 7.27%, respectively. The content of calcium of functional laver added with sericulture powder samples were 219, 253, 224 and 229mg/100g, respectively. The content of potassium of functional laver added with sericulture powder samples were 1879, 1919, 1890 and 1907mg/l00g, respectively. The content of iron of functional laver added with sericulture powder samples were 18.03, 18.23, 18.46 and 18.53mg/100g, respectively. The content of zinc of functional laver added with sericulture powder samples were 1.86, 4.47, 4.57 and 5.64mg/100g, respectively. The content of manganese of functional laver added with sericulture powder samples were 4.50, 8.50, 7.00 and 6.00 mg/100g, respectively. It was concluded that this functional laver added with sericulture powder is low calorie, high protein and high mineral health food which have a preventive effect of adult disease.
