  • To investigate the different mechanism between ATP and compound 48/80 (C$_{48}$80/)-induced histamine release, we observed effects of calcium antagonists in histamine release of rat peritoneal mast cells. Verapamil and diltiazem (voltage-dependent calcium channel blocker) and TMB-8 (a blocker of intracellular calcium release) significantly inhibited ATP-induced histamine release, but did not inhibit $C_{48}$80/-induced histamine release. Econazole (a blocker of receptor-operated calcium channel) dose-dependently inhibited both ATP and $C_{48}$80/-induced histamine release, but inhibitory effect of econazole in ATP-induced histamine release was more potent than that in $C_{48}$80/-induced histamine. EGTA dose-dependently inhibited ATP and $C_{48}$80/-induced histamine release, but $C_{48}$80/-induced histamine release was slightly inhibited by high concentrations (>2 mM) of EGTA. These results suggest that ATP-induced histamine release is related to broth intracellular calcium release and extracellular calcium influx via voltage-dependent calcium channel and receptor-operated calcium channel. $C_{48}$80/-induced histamine release is related to extracellular calcium influx, especially by receptor-operated calcium channel rather than voltage-dependent calcium channel.

  • To elucidate the composition of extractive nitrogenous components in the fresh Capsosiphons fulvescens cultured off the southern coast of Korea, and to determine the monthly variation of these nitrogenous components, extract samples collected monthly from December to March at Jangheung-gun, Jeonnam Province were analyzed for total nitrogen, free and combined amino acids, ATP and related compounds, betaines, trimethylamine oxide (TMAO) and trimethylamine (TMA). The content of extractive nitrogen was 1,090~1,233 mg/100 g on dry basis. The number of 21~25 ninhydrin-positive substances was detected in the analysis of free amino acids, and their total amount was 3,710~4,788 mg/100 g on dry basis. Among them, free proline, asparagine, glutamic acid, alanine, taurine and glutamine were found to be abundant. The combined amino acids amounted to 1,573~2,121 mg/100 g in total and the total amount of ATP and related compound was 33.8~84.0 mg/100 g ($1.06{\sim}2.46\;{\mu}mol/g$) on dry basis. Betaine, glycinebetaine, $\beta$-alaninebetaine, $\gamma$-butyrobetaine, homarine and trigonelline were detected in most of samples. Levels of free and combined amino acids, ATP and related compounds fluctuated from sample to sample, with their contents higher in December and January and lower in March.

  • This study was designed to determine the changes of ATP-related compounds, especially the concentration of IMP, and compares the relationship between IMP and flavor of pork loin chops during storage as three different storage temperatures (include $4^{\circ}C$ CF and PF). Pork loin chops were kept under $4^{\circ}C$ $-1.5{\pm}0.5^{\circ}C$ (control freezing storage) and $-3{\pm}0.5^{\circ}C$ (partially freezing storage). The changes of TBA values, ATP-related compounds, pH values, in CF stored samples were higher than PF stored samples, but it had lower TBA values than $4^{\circ}C$ storage. The IMP concentration reached their peak after 2 days in $4^{\circ}C$, 5 days in CF and 7 days in PF storage, and the ATP, ADP, AMP contents of the loin chops showed minimum, respectively. Flavor of meat sensory score for $4^{\circ}C$ stored samples were more intense (p<0.05) than CF and PF samples on day 2 of storage. However, after storage for 5 days, flavor scores for CF samples were more intense (p<0.05) than $4^{\circ}C$ and PF samples. Flavor scores for PF samples were more intense (p<0.05) than $4^{\circ}C$ and CF on day 7 of storage. As the meat with the peak of IMP contents was most preferred, it was considered that the content of IMP was related to the flavor of meat and that CF, PF had influence on the IMP content.

  • Changes in ATP and related compounds, TMAO, TMA, creatine and creatinine were analyzed to establish the processing conditions for rapid- and low salt-fermented liquefaction of anchovy(Engrulis japonica) extracts during fermentation. Experimental sample A: chopped whole anchovy, adding 20% water, heating at $50^{\circ}C$ for 9 hrs and then adding 10% NaCl. Sample B: chopped whole anchovy, adding 20% water, heating at $50^{\circ}C$ for 9 hrs and then adding 13% NaCl. Sample C: chopped whole anchovy adding 13% NaCl. Sample D: whole anchovy adding 17% NaCl. ATP, ADP, AMP and IMP were broken down during fermentation period, while inosine and hypoxanthine or hypoxanthine were detected in each fermented liquefaction of anchovy. However the amounts of them were varied from collection to collection according to the pretreatment methods. Possibly ATP and their related compounds will not make a great contribution to the umami taste in fermented liquefaction of anchovy. The contents of TMAO were decreased during fermentation period, ranging from 3 to 15 mg/100g in the fermented liquefaction of anchovy after 180 days. The TMA contents were increased slowly during fermentation period, ranging from 60 to 114 mg/100g in the 180 days specimens, however their contents were varied from sample to sample. The contents of creatine and creatinine were increased during early fermentation period, and then they were decreased in the last period. As for distribution of nitrogen in the anchovy extracts, the contribution of creatine and creatinine to the extractive nitrogen was occupying 6.8, 5.7, 4.6 and 5.7% in the experimental sample A, B, C and D, respectively. The contribution of ATP and related compounds to the extractive nitrogen was occupying 2.1, 2.4, 2.2 and 2.7% in the experimental sample A, B, C and D, respectively. The contribution of TMAO and TMA to the extractive nitrogen was very low as they are occupying $0.7{\sim}1.2%$ in the four experimental samples.

  • Quantitative analysis of adenosine triphosphate (ATP) has been widely used as a diagnostic tool in the food and medical industries. Particularly, the pathogenesis of a few diseases including inflammatory bowel disease (IBD) is closely related to high ATP concentrations. A bioluminescent D-luciferin/luciferase system, which includes a luciferase (FLuc) from the firefly Photinus pyralis as a key component, is the most commonly used method for the detection and quantification of ATP. Here, instead of isolating FLuc produced in recombinant Escherichia coli, we aimed to develop a whole-cell biocatalyst system that does not require extraction and purification of FLuc. To this end, the gene coding for FLuc was introduced into the genome of probiotic Saccharomyces boulardii using the CRISPR/Cas9-based genome editing system. The linear relationship (r2 = 0.9561) between ATP levels and bioluminescence generated from the engineered S. boulardii expressing FLuc was observed in vitro. To explore the feasibility of using the engineered S. boulardii expressing FLuc as a whole-cell biosensor to detect inflammation biomarker (i.e., ATP) in the gut, a colitis mouse model was established using dextran sodium sulfate as a colitogenic compound. Our findings demonstrated that the whole-cell biosensor can detect elevated ATP levels during gut inflammation in mice. Therefore, the simple and powerful method developed herein could be applied for non-invasive IBD diagnosis.

  • 염장멸치 제조를 위하여 염장방법 및 숙성온도에 따른 염장 멸치의 숙성 중 유리아미노산 함량과 핵산관련물질 및 관능평가를 조사하였다. 1. 유리아미노산함량은 $5^{\circ}C$에서의 숙성보다는 $20^{\circ}C$에서 숙성한 것이 높았으며, 염장방법에 따라서는 마른간이 물간보다 총 유리아미노산 함량이 높았다. 또한, 마른간은 숙성 120일까지 계속된 증가를 보였으나, 물간은 $5^{\circ}C$에서는 150일까지 $20^{\circ}C$에서는 90일후에는 큰 변화를 보이지 않았다. 2. 염장방법에 따른 ATP 관련물질의 변화는, 숙성이 진행되면서 점차 감소하여, Hx 함량은 숙성이 진행됨에 따라 증가하였으나, 숙성이 거의 완료되는 150일 이후에는 변화가 없었다. HxR은 숙성 초기에 다소 상승하였으나, 숙성 전 기간을 통하여 큰 변화를 보이지 않았으며, IMP는 현저하게 감소하였다. 3. 염장멸치는 숙성기간이 증가함에 따라 맛과 향 등 관능적으로 좋은 평가를 받고 있으나, 색도는 숙성기간에 따라 유의차가 전혀 없었다. 염장온도 $20^{\circ}C$$5^{\circ}C$에서 마른간으로 염장시킨 염장멸치의 종합평가는 각각 120일, 150일의 숙성기간이 경과 후에 유의차를 나타냈으며, 물간에서는 온도에 관계없이 150일 숙성기간 이후에 유의차를 나타났다. 두 방법 모두 $5^{\circ}C$에 숙성시킨 염장멸치가 $20^{\circ}C$ 숙성시킨 것보다 좋은 평가를 얻었다. 이상의 결과로, 염장 멸치의 제조에 적합한 온도는 $5^{\circ}C$이며 150일 (5개월) 숙성시켜야 관능적으로 좋은 제품을 제조할 수 있다. 그러나, 본 연구에서는 육의 연화를 억제시킬 수 있는 염장방법을 모색하는 것으로 물간은 육의 연화를 촉진시키는 현상으로, 염장멸치 제조의 최적조건은 $5^{\circ}C$에서 150일간 마른간을 행하여야 한다.

  • 한국 남해안에서 양식생산되고 있는 김류의 함질소엑스성분 조성 및 월별 변동을 구명하기 위하여 1998년 1월부터 4월까지 월별로 전남 장흥군에서 양식된 잇바디돌김, Porphyra dentata 생엽을 매월 1회씩 채취하여 맛과 밀접한 관계가 있는 함질소엑스성분 즉, 엑스분질소, 유리아미노산, 결합아미노산, ATP관련화합물, 4급암모늄염기 등을 분석하여 방사무늬김, P. yezoensis와 비교하였다. 엑스분질소함량은 760~872 mg/100 g(건물)이었다. 유리아미노산은 27~31종이 분석되었으며, 그 총량은 2,404~3,966 mg/100 g(건물)이었다. 함량이 많은 유리아미노산으로서는 alanine, taurine, glutamine, glutamic acid, aspartic acid 등이었다. 결합아미노산은 가수분해 후 16~23종에서 증가하였으며, 유리아미노산 총량의 36.0~112.0% 수준이었다. ATP관련화합물 총량은 73.3~94.4 mg/100 g(2.04~4.43 $\mu$mol/g, 건물)이었다. Be-taine류로서는 homarine과 trigonelline이 모든 시료에서 검출되었고, $\beta$-alaninebetain과 ${\gamma}$-butyrobetaine은 일부시료에서 검출되었다. TMA는 모든 시료에서 확인되었으며, TMAO는 일부시료에서 분리되었다. 잇바디돌김 생엽의 함질소엑스성분 특징은 방사무늬김에서 처럼 유리아미노산과 결합아미노산 함량이 풍부하여 질소분포의 약 90%에 달하는 중요한 맛성분이었으나 그 성분조성의 월별 변동에는 다소 차이를 보여 대부분의 성분들이 1, 3월에 높고 2, 4월에 낮았다. 잇바디돌김은 방사무늬김에 비해 전반적으로 함질소엑스성분 함량이 약간 낮은 수준이었다.

  • 우리 나라 남해안에서 어획되고 있는 생 멸치의 함질소 엑스성분 조성을 밝히기 위하여 1991년 6월부터 1992년 6월까지 경남 남해군 이동면 근해와 양산군 기장면 대변리 근해어장에서 어획된 생 멸치를 계절별로 각각 4회 수집하여 맛과 밀접한 관계가 있는 함질소 엑스성분 조성을 분석하여 비교하였다. 생 멸치의 엑스분 질소 함량 범위는 $444{\~}773\;mg/100\;g$으로서 높은 때는 낮은 때의 1.7배 이상의 차이가 있었다. 유리아미노산 총량은 $1,049{\~}2,079\;mg/100\;g$이었고, 함량에 있어서 histidine, taurine, alanine, leucine, glutamic acid가 많았다. Oligopeptide류 유래의 아미노산은 $517{\~}l,650\;mg/100\;g$에 달하였고, 유리아미노산 총량의 평균$67.6{\%}$를 차지하였다. ATP 관련 화합물 총량은 평균 $5.02 {\mu}mol/g$이었으며, 그 중 IMP가 대부분을 차지하였다. Betaine류는 glycinebetaine, ${\beta}-alaninebetaine,\;{\gamma}-butyrobetaine$, 및 homarine 이 검출되었으나, 미량에 불과하였다. TMAO와 TMA는 평균 $164mg 과 16mg/100g$ 검출되었고, creatine과 creatinine은 평균 229 mg과 7 mg/100g 검출되었다. 엑스분 중의 질소분포는 지역이나 계절별로 유사한 조성을 나타내었으며, 질소의 회수율은 평균 $93.7{\%}$이었다. 멸치의 함질소 엑스성분에 대한 지역차를 보면 남해산은 기장산 보다 엑스분 질소, 유리아미노산, oligopeptide류, betaine류 및 creatine함량이 높았으나, ATP 관련화합물과 TMAO는 낮았다. 봄멸치는 가을멸치보다 엑스분 질소, 유리아미노산, oligopeptide류, ATP관련물질 및 betaine류가 높았으며, TMAO와 creatinine 함량은 낮았다.

  • 본 실험에서는 동결된 홀스타인 안심육을 해동하여 다시 냉장시켰을 경우 물리화학적 성질과 관능특성이 가열육의 기호성을 향상시킬 수 있도록 변하는지를 검토하기 위해서 전단력가, 근원섬유 소편화율, 30KD의 출현 정도, 생육향 및 연도 그리고 가열육의 기호성에 대하여 조사하고 아미노산 함량과 ATP 관련 화합물의 차이도 비교하였다. 냉장 안심육은 생육향(p<0.01), 연도(p<0.05), 전단력가(p<0.05), 근원섬유의 소편화율(P<0.01) 및 30KD 성분의 출현 정도(p<0.001)가 동결 안심육 보다 우수하였으며, 동결육을 해동하여 다시 $3^{\circ}C에서$ 냉장하므로써 동결육 보다 전단력가(p<0.05), 근원섬유의 소편화율(p<0.001) 및 30KD성분(p<0.001)이 현저하게 우수하였고 연도(p<0.05)가 향상되고 생육향(p<0.05)도 좋아졌다. 동결 해동한 후 다시 냉장한 안심육을 가열하였을 때에도 해동 직후의 안심육에 비하여 가열육향과 텍스쳐가 향상되었으며, 기호성(p<0.05)도 현저하게 좋아졌다. 그러나 후각을 차단한 상태에서만 느껴지는 맛은 유의한 차이가 없었다. 그리고 동결 해동 후 다시 냉장한 안심육은 해동 직후의 안심육 보다 aspartic acid 및 leucine 함량이 많아졌고 (p<0.05) IMP 함량이 적었으며 (p<0.05), hypoxanthine (p<0.05)과 inosine의 함량은 많아졌다.
