  • 대마는 인류가 이용해 온 가장 오래된 약제 중 하나로 그 원산지는 중앙아시아와 남아시아이다. 식물분류학적으로 대마속 일년생 식물로서 Cannabis sativa, Cannabis indica, Cannabis ruderalis 3종이 있으며, 우리나라에서 재배되고 있는 종은 Cannabis sativa이다. 대마 재배의 역사는 인류의 시작과 그 궤를 같이하며, 동 서양을 막론하고 고대 문명에서 대마에 대한 기록을 쉽게 찾아볼 수 있다. 기록에 의하면 병의 치료나 심리적 치유 및 신에게 제사를 올릴 때 제사장이 사용한 것으로 알려져 있다. 대마의 약효에 대하여는 B.C. 2737년 중국의 신농황제시대의 기록에 관절염과 통증등 의료목적으로 사용했던 최초의 기록이 있으며 본초강목과 동의보감에 저술되어 있다. 우리나라의 대마에 관한 문헌 기록은 삼국지 '위지동이전', 삼국사기 '동성왕편'과 삼국유사에 삼베를 사용한 기록이 있는 것으로 미루어 봤을 때 대마재배의 역사는 삼국시대 이전으로 볼 수 있다. 우리 민족은 생활 속에서 대마를 즐겨 사용하였으며 삼베로 의복과 멍석, 행주 그리고 칠공예품이나 신발등을 만들어 사용하였으며, 죽음에 이르러 삼베옷을 수의로 사용하였다. 대마의 용도는 뿌리, 줄기, 잎, 꽃대 그리고 씨앗까지 다양하게 이용된다. 전통적으로 줄기의 껍질을 이용한 섬유제품이 있으며 실, 의복 및 밧줄등이 있다. 대마 줄기의 속대는 종이, 건축자재, 연료로 사용된다. 씨앗의 경우 식품과 조류의 먹이, 생약으로 이용되고 씨앗의 기름은 연료, 화장품, 맛사지 오일등으로 사용되고 있다. 환각성분이 있어 마리화나 원료로 사용되는 꽃대와 잎은 의약품의 원료로 주목받고 있다. 대마에 관한 최초의 논문은 1843년에 Cannabis indica의 약효에 관한 것으로 보고되었다. 1850년부터 1937년까지 미국의 약전은 대마를 100가지 이상의 질병에 효과가 있는 주요 의약품으로 기재하고 있다. 세계적으로 여러 가지 이유로 대마를 의료 응용과 연구 및 사용을 제한하여 대마에 관한 연구가 침체되었다. 대마의 의학연구는 대마의 약효성분인 칸나비노이드의 발견과 그 구조 및 약효에 관한 연구가 시작되면서 1960년대부터 증가하였으며 2000년 이후에는 칸나비노이드 및 칸나비디올의 다양한 의학적 효과가 밝혀지면서 급격히 증가하고 있다. 대마에 포함된 성분의 의학적 효과가 입증되면서 대마 사용을 합법화한 국가가 증가하면서 대마 산업이 급부상하고 있으며, 의료용뿐만 아니라 기호용, 식품용, 그리고 주류 및 음료시장까지 확대되고 있다. 우리나라도 2019년 3월 질병 치료 목적 대마성분 의약품을 제한적으로 허용하는 마약류 관리에 관한 법률 일부 개정안이 시행되면서 의료용 대마에 관한 연구와 산업화에 관심이 증가하는 추세이다.

  • This study was conducted to investigate the changes of isoflavone composition (glycoside and bio-active aglycone) in Cheonggukjang and to evaluate its quality characteristics depending on different soybean cultivars (Daewon, Daepoong, Wooram, Hwangkeumol and Saedanback). The bioactivity of Cheonggukjang was enhanced during fermentation at $37^{\circ}C$ for 48 h. Activities of ${\alpha}$-amylase, protease, and cellulase increased significantly after 48 h fermentation (p<0.05). In addition, amino-type nitrogen and reducing sugar contents in Cheonggukjang fermented with B. subtilis increased significantly after 48 h fermentation (p<0.05). Among the isoflavones, the content of $\beta$-glucosides and acetyl-glucosides decreased, while aglycone content increased during fermentation. Especially, Cheonggukjang fermented with Daepoong cultivars showed the greatest increase in daidzein, genistein and glycitein contents. After 48 h fermentation, the contents of daidzein, genistein and glycitein in the Cheonggukjang fermented with Daepoong cultivars increased significantly up to $503.65{\pm}2.76$, $111.40{\pm}0.42$, and $633.95{\pm}6.01{\mu}g/g$ (p<0.05), respectively. Total aerobic and anaerobic cell counts increased with increase in fermentation time. Therefore, it would be beneficial for the food industry if components of Cheonggukjang could be separated and used to develop functional products.

  • Black rice bran powder has potential medical uses and functionality. In this study, we assessed the antioxidant activity and quality characteristics of cookies containing various concentrations (0, 1, 3, 5, 7, and 9%) of black rice bran powder. To analyze quality characteristics, proximate composition, fatty acid composition, amino acid composition, bulk density and pH of the dough, spread factor, loss rate, leavening rate, color, texture profile analysis, and sensory evaluations were measured. Black rice bran cookies (7%) contained more crude protein ($10.67{\pm}0.33$%) compared to control ($5.84{\pm}0.06$%). The total unsaturated fatty acid contents of the control and 7% black rice bran cookies were 30.44 and 30.81%, respectively. The amino acid content of 7% black rice bran cookie was higher than that of control. Bulk density of the dough, moisture, spread factor, total polyphenol content, and DPPH free radical scavenging activity of the cookies significantly increased with increasing content of black rice bran powder, whereas pH of the dough, loss rate, leavening rate, and L values of the cookies decreased. Additionally, consumer acceptability scores for the 7% black rice bran cookie group ranked significantly higher than those of the other groups in terms of appearance, taste, flavor, texture, and overall preference. Taken together, the results of this study suggest that black rice bran powder is an effective ingredient for increasing the consumer acceptability and functionality of cookies.

  • This research investigated the effect of different onggi containers (Korean earthenware) on the ripening of kochujang (Korean hot pepper paste). The physical characteristics of 'onggi', were evaluated as function of manufacturing variables such as raw material soils (onggi-specific soil, red brown soil, and fine powdered soil) and galzing treatments. The physical properties were then related to the compositional quality changes of the kochujang fermented at $30^{\circ}C$ for 4 months. The porosity of the onggi containers seems to be increased by the content of finer raw soil rather than the chemical component of soil (amount of CaO, MgO, $K_2O$ and $Na_2O$, acting as melting aid in the firing). Natural glaze was measured to contain higher contents of CaO, MgO, $K_2O$ and $Na_2O$ than the other soils, which is desirable property for the fired onggi. The glazed surface showed higher far-infrared radiation emissivity than the non-glazed part. The kochujang fermented in P0-BG (the glazed onggi from 100 % onggi soil) attained higher concentration of reducing sugar, amino nitrogen and nucleotides compared to those in the other onggis. All of these changes of kochujang in P0-BG resulted in significantly better sensory quality than the other treatments.

  • Pork cutlets containing ginseng powder 1% + ginseng distillate 1%(P1/D1), ginseng powder 2%(P2), ginseng powder 1.5% + ginseng distillate 1.5%(P1.5/D1.5) and ginseng powder 3%(P3) were manufactured and compared with the control(no ginseng powder and distillates) in meat quality, sensory evaluation and flavor intensity. The L values were significantly lower and a values were significantly higher for pork cutlets containing ginseng additives as compared to the control. The pork cutlets containing ginseng powder and distillates were higher in hardness only at the beginning stage, but no significant differences in springness, cohesiveness and chewiness among the treatments were observed during storage at -20$^{\circ}C$ for 8 weeks. Flavor analysis indicated that spathulenol, panasinsanol, neointermedol and ginsenol were responsible for ginseng flavor. The sensory panels detected most intense ginseng flavor and taste for pork cutlet which contained combination mixtures of ginseng powder 1.5% and distillate 1.5%. In conclusion, sensory panels evaluated that ginseng distillates produced intense ginseng flavor and enhanced ginseng flavor when used as mixtures with ginseng powder. Therefore, ginseng distillates can be used as a natural antioxidant and flavor enhancer in pork products.

  • For the effective use of under-utilized resources, silver-stripe round herring (SSRH), the plain-dried SSRH was investigated and compared with boiled-dried SSRH and boiled-dried anchovy on the food component and sensual characterization. Moisture content and salinity of the plain-dried SSRH were 31.9% and 7.6%, respectively. Moisture content of the plain-dried SSRH was higher, while the salinity was lower than those of boiled-dried SSRH and anchovy. According to the results of peroxide value, fatty acid composition, Hunter b value, and browning index, the rancidity was higher in plain-dried SSRH than in boiled-dried SSRH and anchovy. When compared to the boiled-dried SSRH and anchovy, the plain-dried SSRH was higher in calcium and phosphorus contents, while lower in total content of amino acid. According to the results of hot-water soluble-N, trichloroacetic acid-N, free amino acid, and taste value, the taste of plain-dried SSRH was superior to those of the boiled-dried SSRH and anchovy. The results of chemical components and sensory evaluation indicated that the plained-dried SSRH could be substituted for boiled-dried anchovy classified into special grade, if fish odor of SSRH can be improved.

  • Volatile flavor components in the fruits of dried Zanthoxylum schinifolium were extracted by supercritical fluid extraction method using diethyl ether as solvent. Essential oils were analyzed by gas chromatography (GC) and combined gas chromatography-mass spectrometry (GC-MS). Identification of volatile flavor components was based on the RI of GC and mass spectrum of GC-MS. A total of 30 components, including 6 hydrocarbons, 4 aldehydes, 8 alcohols, 5 esters, 4 acids and 3 miscellaneous components were identified in the essential oils. Geranyl acetate, ${\beta}$-phellandrene, D-limonene and citronellal were found to be major volatile flavor components in fruits of dried Zanthoxylum schinifolium. The masking effects of Zanthoxylum schinifolium on meaty and fishy flavor were measured by sensory evaluation to investigate the usefulness of Zanthoxylum schinifolium as a natural spice. Meaty flavor was significantly reduced with the addition of 0.05% and 0.1% Zanthoxylum schinifolium. And the addition of 0.l% powdered Zanthoxylum schinifolium also reduced the fishy flavor of mackerel.

  • In this study, we produced kimchi with cooked Dioscorea batatas yam. Sliced kimchi cabbage, processed white radish kimchi (kkakdugi), and whole kimchi cabbage were prepared with 3% Dioscorea batatas, the nutritional and sensory properties were evaluated. The three types of D. opposita kimchi showed energy content in the range of 35-40 kcal per 100 g, and no crude fat, saturated fat, trans fat, or cholesterol was detected. Sodium content was 450-650 mg, with sliced cabbage kimchi showing the highest concentration. The vitamin C content increased significantly after 28 days of storage, with the sliced cabbage kimchi and whole-cabbage kimchi showing larger increases than the radish kimchi. All three types of D. opposita kimchi showed high Ca, K, and Mg contents. The whole-cabbage kimchi maintained salinity at a level of 2.38-2.72% from immediately after preparation to 28 days of storage compared to sliced cabbage kimchi and radish kimchi. Sliced cabbage and whole kimchi cabbage kimchi showed an increase in lightness and a decrease in redness with longer storage duration. Compared to the control groups, the experimental groups (with added D. opposita) showed higher yellowness. The hardness of the three types of kimchi decreased with longer storage duration. In sensory evaluation, there were no significant differences between the control groups and the experimental groups.
