  • This research is to establish the basic data of the nutritive value and improve our diet. In the part of the leaf and stem of the wild and cultivated horned rampion (Phyteuma japonicum Mig), the components such as chemical compositon, vitamin C, free sugar, mineral, nucleotide and its related compounds, composition and free amino acid were analyzed one after another. Content of the crude lipids and proteins was determined much higher in its wildness than in its cultivated horned rampion; while, that of carbohydrates was higher in the former than in the latter. The content of vitamin C was retained higher in the leaf than in the stem horned rampion. And the content of calcium among the detected minerals was outstanding in all of the samples collected, and potassium and magnesium was the next ones in its order. The main components of free sugars in both the wild and cultivated horned rampion were glucose and fructose, and their content was higher in the stem than in the leaf. Nucleotide and its related compounds were identified with 5 kinds of nucieotides such as CMP, UMP, IMP, AMP and hypoxanthine (Hx), and the content of Hx and AMP was the highest I the wild and cultivated samples, respectively. In the composition amino acid of the wild horned rampion, glutamic acid, aspartic acid and phenylalanine was outstandingly abundant; while, such amino acid as methinone and proline was small and besides cysteine couldn't be detected in the stem. Total amounts of composition amino acid in the leaf was 2118.0 and 1120.1mg% in the wild and cultivated sample, respectively. In the free amino acid of horned rampion, the total amount ranged from 8.5 to 50.1mg.%, which were lower level than that of composition amino acid. But the number of free amino acid was 29 kinds, which was bigger in its number than that of composition amino acid detected 17 kinds.

  • Fat shot은 골프에서 공보다 뒤땅을 먼저 치게 되는 샷의 공식 용어이다. 본 연구에서는 fat shot과 정상적인 샷의 동작을 비교 분석하였다. K 대학교 교원 5명을 연구대상자로 선정하였으며, 개인별 fat shot이 최소 5개 체크될 때까지, 샷을 계속하게 하였다. AD, MBS, TBS, MDS, IMP, MF를 분석 시점으로 설정하였고, 구간 소요시간, 지면반력 패턴, 백스윙 크기, 팔꿈치 각도, 코킹 각도, 골반과 몸통의 회전, 골반 선속도 각속도 등을 분석하였다. 변인별 차이를 확인하기 위해 대응표본 검증을 실시하였다. Fat shot의 주요 원인으로 간주되는 다운스윙에서의 빠른 코킹 풀림, 다운스윙 초기의 오른 팔꿈치 신전, 뒷발에 체중을 실은 채로 하는 스윙 등의 형태는 나타나지 않았다. 백스윙 크기와 X-Factor 크기, 골반과 몸통의 회전각도, 골반의 회전각속도에서도 두 샷 간 차이가 나지 않았다. 그러나 정상적인 샷에 비해 Fat shot은 다운스윙 초반이 아닌, 후반부 임팩트 바로 직전의 다소 급격한 체중 이동 형태와 다운스윙 과정 중 골반의 타겟 방향으로의 급격한 가 감속, 그리고 골반의 수직 상방으로의 다소 작고 늦은 타이밍의 움직임 속도패턴을 나타내었다.

  • The purpose of this study was performed as model study using four animals to investigate the correction between the changes in Differential Scanning Calorimetry thermogram of muscle proteins during storage and meat freshness. M. longissimus dorsi of pork was obtained immediately after slaughter and chilled/stored at either $-2^{\circ}C$ or $25^{\circ}C$ for up to 96 h for analyses. DSC thermograms were determined and compared with pH values, ATP-related compounds, K-values, volatile basic nitrogen (VBN) levels, bacterial counts and electrophoretic behavior. Changes in pH, bacterial counts, VBN and K-values were associated with increased storage temperature and time. The levels of pH values, bacterial counts, VBN and K-values of pork samples stored at $25^{\circ}C$ were higher than those of the pork samples stored at $-2^{\circ}C$. ATP concentration decreased faster in samples stored at $25^{\circ}C$. Only IMP increased in samples stored at $-2^{\circ}C$, whereas the concentration of hypoxanthine and inosine increased in samples stored at $25^{\circ}C$. One exothermic peak and two endothermic peaks appeared on the thermograms of pork stored at either temperature. Lower transition temperature of myosin, sarcoplasmic protein and actin peaks were observed. The freshness parameters of K-value, VBN and hypoxanthine showed highly negative correlations (-0.742- -0.9980) to the changes in transition temperature. Therefore, the shift temperature on DSC thermogram can be used as an indicator of the freshness parameters of meat.

  • Alkali treatment following acidic hydrolysis (ATAH) is a commonly used practice for reducing the levels of monochloropropanediol in commercial Korean soy sauce. This study investigated the chemical compounds produced in commercial Korean soy sauce made by ATAB. The levels of amino-N, total acidity, pH, salinity and Brix of the soy sauce were 6.66%, 2.52%, 19.81%, 4.57 and 35.01, respectively. The major fatty acids were C18:2n-6, C16:0, Cl8:ln-9 and C18:3n-6. The concentration of polyunsaturated fatty acids were especially high, with of C18:2n-6 (49.8%) being the highest followed by C18:3n-6 (3.8%) and C18:3n-3 (2.4%) in that order. Among the non-volatile organic acids, the concentration of levulinic acid (1,206.28 mg/100 g) was the highest, while the taste value of citric acid was the highest. Among the ATP related compounds, IMP concentration (31.19 mg/100 g) was highest followed by AMP, hypoxanthine and GMP in that order. The concentrations of free and total amino acids in soy sauce were 6,136.94 mg/100 g and 8,702.76 mg/100 g, respectively. On the other hand, the taste value of glutamic acid, a major amino acid flavor determinant in soy sauce, was highest of all the amino acids, which is desirable since most free amino acids such as methionine, histidine and phenylalanine have a bitter taste that detracts from the flavor of soy sauce.

  • This study was red snow crab Chionoecetes japonicus cooker effluent (RSCCE) for making a natural crab-like flavorant. The RSCCE ($1\;^{\circ}Brix$ in the initial state) was concentrated up to $40^{\circ}Brix$ to determine the optimal conditions for making a natural flavorant. During concentration, the amino-N content and total acidity increased with the concentration time, while the pH was maintained in range 7.94-8.78. In the acceptance test and quantitative description analysis (QDA), $20^{\circ}Brix$ RSCCE had the best quality in terms of taste (5.87), odor (6.00), and overall acceptance (5.80). Of the taste compounds analyzed in $20^{\circ}Brix$ RSCCE, lactic acid was an abundant non-volatile organic acid, and the nucleotide 5'-inosine monophosphate (IMP) was present, as were four free amino acids: tyrosine, glutamic acid, alanine and glycine. The taste and odor of boiled crabmeat were retained in $20^{\circ}Brix$ RSCCE based on the QDA.

  • Snow crab Chionoecetes japonicus cooker effluent (SCCE) is a processing byproduct that is produced in large quantities during snow crab processing. However, it is typically discarded due to the lack of a suitable application or used only as a seasoning following simple concentration. We performed a series of studies to make crab-like flavorings (CFs) from SCCE using response surface methodology and reaction flavor technology. To develop material for CFs, taste compounds in the precipitate of SCCE (PSCCE) and the enzymatic hydrolysate of PSCCE (EHSCCE) were analyzed. The content of free amino acids in EHSCCE was 21.6 times higher than that in PSCCE. The major compounds in PSCCE were arginine, glycine, taurine, alanine and sarcosine in that order; leucine, phenylalanine, arginine, valine and lysine were the major compounds in EHSCCE. Six nucleotides and related compounds were identified in EHSCCE. Hypoxanthine ($40.3{\mu}g/100g$) was the most abundant, followed by 5'-GMP ($22.9{\mu}g/100g$), ADP ($22.5{\mu}g/100g$), AMP ($21.0 {\mu}g/100g$), inosine ($3.6{\mu}g/100g$) and 5'-IMP ($2.3{\mu}g/100g$).

  • Changes in the nutritional components of Toha-jeot, salt-fermented Toha shrimp (Caridina denticulata denticulata $D_EH_{AAN}$), which was salted with a low-salt group of 15% sodium chloride (L), a high-salt group of 23% sodium chloride (H), a 50% conventional soybean sauce group (S) during long fermentation were investigated. These three groups were refrigerated at ${4\pm}1^{\circ}C$ and then taken out for analysis at three month intervals during 9 month. Even in the process of a long fermentation, the moisture containment of Toha-jeot in group L and S is 76.0~73.6% and in group H it is 70.0%, which are similar in all three groups. In case of the salinity, there was no change in groups L, H but it was lowered in group S during the fermentation. In all groups there was no change of pH. The free amino acid contents in Toha-jeot, of which ornitine, glutamic acid, leucine, alanine, lysine and valine occupy the majority, in order of abundance, increased gradually up to six months of fermentation and decreased by nine months. But free amino acid contents of S group increased continuously during the fermentation process. Hypoxanthine was altered almost among other nucleotides. ATP was not detected, IMP and inosine had disappeared after the six months for mentation. ADP was not detected after the nine months fermentation. Monoene, polyene and n-3 fatty acids were increased and saturated fatty acids were decreased in L and H groups. However, no changes of fatty acid contents in S group during fermentation were showed. The fatty acid contents of three groups, of which $C_{18:1},\;C_{16:0},\;C_{16:1}$ and $C_{20:5}$ occupy the majority, Mineral content of Toha-jeot is mainly consisted of Na, Ca, K and Mg. In the Hunter values, the redness of L group was superior to that of other groups.
