본 연구는 국내산 밀 품종에 따른 제분율 별로 밀 막걸리의 품질특성을 평가하고자 수행하였다. 원료곡의 탄수화물은 70% 제분율의 금강밀, 백중밀이 78.37, 78.16%로 가장 높았다. 밀의 품종 및 제분율에 따른 막걸리의 품질특성을 검정한 결과, 가용성 고형분 함량, 환원당, 알코올은 각각 $10.94{\sim}12.33^{\circ}Brix$, 2.89~4.71%, 14~15.97% 범위를 나타냈으며 백중밀 70% 제분율에서 알코올 15.97%, 환원당 4.71%로 가장 높은 함량을 나타냈다. 밀 막걸리의 glucose 함량은 159.4~560.7 mg%의 범위를 보이며 원료 밀 대비 상당량 증가하였고 그 외 mannitol과 arabinose도 존재하였다. 밀 막걸리의 유기산 분석에서, 유산균에 의한 대사산물인 lactic acid는 85.3~650.3 mg%의 분포를 나타내며 가장 높은 수준을 나타냈고 제분율 증가에 따라 그 함량도 증가하였고 제분율별 품종 비교에서는 조경밀이 가장 높았다. 밀 막걸리의 품질 관련인자의 상관성 분석에서는 원료곡의 단백질 함량은 밀 막걸리의 총산, 환원당과 부의 상관을 보였고(p<0.001), 원료곡의 탄수화물 함량은 밀 막걸리의 총산, 환원당(p<0.001) 및 알코올 함량(p<0.05)과 정의 상관을 나타내었다. 가용성 고형물의 함량은 알코올, 환원당 함량과 정의상관을, pH와는 부의 상관관계를 나타내었다(p<0.001). 밀 막걸리의 알코올 함량 비교 시 70, 85% 제분율에서 품종과 제분율에 따른 차이가 존재하지 않았으므로 85% 밀가루도 막걸리용으로 이용 가능할 것이라 생각된다. 하지만 품종과 제분율에 따라 함유하는 유리당과 유기산 등 여러 가지 품질특성이 상이하기 때문에 이를 고려한 원료의 선택이 필요할 것이다. This study aimed to evaluate the quality characteristics of wheat-Makgeolli (WM), a traditional Korean cereal alcoholic drink, using three varieties of wheat, namely Jokyoung (JK), Baegjoong (BJ) and Keumkang (KK). Samples of WM brewed from 100%, 85% and 70% milling rates of the three Korean wheat cultivars were analyzed for alcohol, pH, coloring degree, total acids, soluble solid, free sugars, and organic acids. As the milling rates in wheat decreased, total sugar content in WM increased while the pH of all samples decreased. The WM exhibited 0.95~1.27% in acidity, $10.2{\sim}12.5^{\circ}Brix$ in total sugar, and 14~16% in alcohol content. The most organic acids in WM was lactic acid, ranging in all the samples from 85.3~650.3 mg%. The results showed that BJ under a 70% milling rate had the highest reducing sugar contents and 15.97% in alcohol content. The carbohydrate content increased with the milling rate of wheat. Resulting in a positive correlation between carbohydrate content of wheat and total acids, reducing sugars (p<0.001), and alcohol content (p<0.05) in WM. Total sugar content is positively correlated with alcohol and reducing sugar content (p<0.001). Considering the yield, the milling rates will be adjusted to raw material prices.

쌀음료베이스 개발을 위한 품종별 가공용 쌀의 기초자료 확보를 위해 국내산 쌀 7종(삼광, 일품, 설갱, 안다, 다산1호, 고아미4호, 단미)과 수입쌀 3종(미국쌀, 중국쌀, 태국쌀)을 대상으로 수화, 호화 및 당화 관련 특성을 살펴보았다. 품종별쌀의 수분함량은 11.88~15.26% 범위로 나타났으며, 수분흡수율은 안다, 미국쌀이 가장 높게 나타났다. 수분결합력은 태국쌀이 가장 높았으며, 단미, 고아미4호 및 설갱은 낮은 수분결합력을 나타내었다. 용해도는 10종의 시료 중 단미가 월등히 높은 26.6%를 나타내었으며, 팽윤력은 설갱, 안다, 미국쌀이 유의적으로 높은 수준을 나타냈다(p<0.05). 품종별 쌀가루의 아밀로오스 함량은 고아미4호와 태국쌀이 가장 높은 반면, 단미가 가장 낮았다. RVA를 측정한 결과, 호화온도는 단미와 고아미4호가 각각 $91.6^{\circ}C$와 $78.5^{\circ}C$로 가장 높았고, 그 외 품종은 $68.0{\sim}71.1^{\circ}C$로 나타났다. 최고점도와 최종점도는 다산1호가 가장 높았고, 단미가 가장 낮게 나타났다. 치반점도는 일품과 미국쌀이 낮게 나타나, 노화가 더디게 진행될 것으로 예상되었다. 한편, 쌀, 수침처리 쌀, 건식쌀가루, 습식쌀가루로 가공용 쌀 전처리를 달리하고, 수침시 흡수되는 수분량을 고려하여 물을 첨가하고, 고온용 ${\alpha}$-amylase 처리 후 당화특성을 비교하였다. 당화액의 pH는 일품을 제외한 모든 품종에서 습식쌀가루가 유의적으로 높게 나타났다(p<0.05). 가용성 고형분 함량은 대부분 수침처리한 것보다 수침처리하지 않는 것, 쌀보다는 쌀가루의 효소처리가 더 효과적으로 높게 나타났다. 환원당 함량은 전처리 방법에 따라 수침처리하지 않는 것보다 수침처리한 것, 쌀보다는 쌀가루가 유의적으로 더 높게 나타났다(p<0.05). 색도는 L값의 경우 고아미4호를 제외한 대부분 품종에서 쌀보다 수침처리한 쌀이 낮은 값을 보였다. a값은 수침처리하지 않는 쌀과 습식쌀가루에서 낮은 값을 보였으며, b값은 쌀보다 수침처리한 쌀, 건식쌀가루보다 습식쌀가루가 품종에 따라 다소 차이가 있는 것으로 나타났다(p<0.05). 이러한 연구결과를 종합해 보면, 쌀을 원료로 한 음료베이스 개발을 위해서는 원료곡의 호화, 액화 및 당화에 영향을 주는 여러 가지 인자와 품종별 특성을 고려한 접근이 이루어져야 할 것이다. This study evaluated the hydration, gelatinization, and saccharification properties of rice processing for beverage development. The properties of rice were studied on 10 rice cultivars (Samkwang, Ilpum, Seolgaeng, Anda, Dasan-1, Goami-4, Danmi, American rice, Chinese rice, and Thai rice) and employing four kinds of pre-treatment methods (dry grain, wet grain, dry flour, and wet flour). The results showed that moisture content of rice was between 11.88~15.26%. Increase in soaking time along with highest water absorption was noted in American rice cultivar (46.81%). The water binding capacity of Thai rice was higher when compared to that of other rice flours. In addition, solubility and swelling power of rice were 4.52~26.65% and 0.19~2.05%, respectively. The amylose content of Goami-4 was higher in rice processing. Using a rapid visco analyzer (RVA), the initial pasting temperature of Danmi cultivar was found to be the highest; the peak viscosities of Anda cultivar and Dasan-1 cultivar, and Chinese rice were higher than of those of other rice flours. After saccharification, the pH, soluble solids content, and reducing sugar content of rice processed through different pre-treatment methods were in the range of 6.22~7.08, $4.67{\sim}16.07^{\circ}Brix$, and 0.35~11.67% (w/w), respectively. In terms of color values, the L-value of dry grain, a-value of wet (grain, flour), and b-value of dry sample (grain, flour) were found to be the highest. Assessment of various factors and cultivars characteristics of the raw grains are of importance in the development of rice beverage.

본 연구에서는 보리와 밀 혼합막걸리의 품질특성으로 이화학적 특성, 색도, 환원당, 유기산, 효모수, 관능적 특성을 조사하였다. 보리는 흰찰쌀보리를 이용하였고, 금강밀, 백중밀, 조경밀을 1:1로 혼합하고 수입밀과 쌀을 대조구로 하여 $25^{\circ}C$에서 7일간 발효 후 착즙한 술덧을 시료로 하였다. 이화학적 특성으로 pH, 총산, 당도 및 알코올 함량을 측정한 결과, pH는 4.04~4.12로 밀 품종에 따른 유의적인 차이는 없었고, 총산은 0.94~1.06%로 나타났다(p<0.05). 당도는 밀 혼합막걸리가 $12.67{\sim}13.44^{\circ}Brix$ 수준으로 쌀 혼합 막걸리 $11.76^{\circ}Brix$에 비해 높게 나타났으며, 알코올 함량은 15.13~16.53%의 범위로 나타났다. 밀 품종간 색도 L값의 유의적인 차이는 없었고, a값은 0.26~0.60 범위를 보였으며, b값은 밀 혼합막걸리가 쌀 혼합막걸리 보다 유의적으로 높아 좀 더 황색에 가까웠다(p<0.05). 환원당은 5.65~7.85 mg/mL의 범위로 나타났으며, 유기산은 금강 밀 혼합막걸리에서 lactic acid를 제외한 citric acid, malic acid, pyruvic acid가 가장 높게 검출되었다. 효모수는 밀이 혼합된 막걸리가 7.17~7.46 logCFU/g으로 쌀이 혼합된 막걸리 6.06 logCFU/g 보다 더 높았다. 관능적 특성에서 우리밀과 수입밀 간의 유의적은 차이는 없었으나, 맛은 백중밀이 가장 높게 나타났다(p<0.05). 이러한 결과로 보리 막걸리 제조 시 황색도, 효모수, 맛 등에서 높은 수준을 보였던 우리밀이 보리 막걸리 제조 시 혼합 곡물로 더 적합하였다. 따라서 밀 원료를 수입밀에서 금강밀이나 백중밀로 대체 시 일부 품질 증대와 함께 원료국산화에 따른 막걸리 프리미엄화 전제조건을 충족시킬 수 있을 것으로 기대된다. This study was conducted to evaluate the quality of barley (Huinchalssalbori) and domestic wheats (Keumkangmil, Baegjoongmil, Jogyeongmil). The pH and total acidity of mixed Makgeolli were 4.04~4.12% and 0.94~1.06%, respectively. The total acidity, sugar and alcohol contents of Makgeolli, but not pH, varied significantly by wheat cultivar (p<0.05). In terms of color values, the L-value of Baegjoongmil, a-value and b-value of Keumkangmil were highest. The reducing sugar contents was approximately 5.65~7.85 mg/mL, and those of Jogyeongmil and imported wheat were approximately 5.70 mg/mL lower. The yeast cell numbers did not differ significantly, with the exception of in the rice Makgeolli (p<0.05). Among the organic acids (citric, malic, pyruvic and lactic acids) in Makgeolli, citric acid was present at the highest concentration. Regarding the sensory characteristics of Makgeolli mixed with barley and wheat, taste and overall acceptability were highest in Baegjoongmil, and appearance and flavor were highest in Keumkangmil. The rice Makgeolli showed the lowest sensory values, with the exception of appearance. The results of this study suggest that mixing Makgeolli with barley and wheat is an expected to replace the wheat materials in the domestic wheat to be imported.

Determination of methamphetamine and amphetamine enantiomers in human urine by chiral stationary phase liquid chromatography-tandem mass spectrometry

Sim, Yeong Eun,Ko, Beom Jun,Kim, Jin Young The Korean Society of Analytical Science 2019 분석과학 Vol.32 No.5

Methamphetamine (MA) is currently the most abused illicit drug in Korea and its major metabolite is amphetamine (AP). As MA exist as two enantiomers with the different pharmacological properties, it is necessary to determine their respective amounts in a sample. Thus a chiral stationary phase liquid chromatography-tandem mass spectrometric (LC-MS/MS) method was developed for identification and quantification of d-MA, l-MA, d-AP, and l-AP in human urine. Urine sample ($200{\mu}L$) was diluted with pure water and purified using solid-phase extraction (SPE) cartridge. A $5-{\mu}L$ aliquot of SPE treated sample solution was injected into LC-MS/MS system. Chiral separation was carried out on the Astec Chirobiotic V2 column with an isocratic elution for each enantiomer. Identification and quantification of enantiomeric MA and AP was performed using multiple reaction monitoring (MRM) detection mode. Linear regression with a $1/x^2$ as the weighting factor was applied to generate a calibration curve. The linear ranges were 25-1000 ng/mL for all compounds. The intra- and inter-day precisions were within 3.6 %, while the intra- and inter-day accuracies ranged from -5.4 % to 11.8 %. The limits of detection were 2.5 ng/mL (d-MA), 3.5 ng/mL (l-MA), 7.5 ng/mL (d-AP), and 7.5 ng/mL (l-AP). Method validation parameters such as selectivity, matrix effect, and stability were evaluated and met acceptance criteria. The applicability of the method was tested by the analysis of genuine forensic urine samples from drug abusers. d-MA is the most common compound found in urine and mainly used by abusers.

The comparison of operative outcomes between “Energyless” myomectomy and the conventional myomectomy

( Yeong Eun Sim ),( Jeong Sook Kim ),( Jin Young Choi ),( Da Sol Oh ),( Jun Woo Ahn ),( Soo Jeong Lee ),( Hyun Jin Roh ),( Sang Hun Lee ) 대한산부인과학회 2022 대한산부인과학회 학술대회 Vol.108 No.-

Objective: Advance in surgical energy devices facilitates hemostasis and tissue dissection in various surgical fields including myomectomy to preserve the fertility in young patients. However, the use of energy devices can cause the thermal injury to myometrium or endometrium during myomectomy, which may adversely affect the subsequent pregnancy or the fertility. Here, we performed myomectomy without energy device and assessed its perioperative outcomes. Methods: Retrospective non-inferior study was conducted with 253 patients who underwent myomectomy between December 2016 and December 2021 at the Department of Obstetrics and Gynecology, Ulsan University Hospital. 188 Patients underwent conventional myomectomy, and 65 patients did ‘energyless myomectomy in which uterine incisions were made using scissors and bleeding was controlled by vasopressin injection and suture. Perioperative outcomes were evaluated according to several indices such as expected blood loss (EBL), operation time (OP time), perioperative change in the level of hemoglobin, and the day of hospitalization. Results: The demographic characteristics between the two groups showed no difference in age, body mass index, and gravida. Analysis did not reveal any differences in EBL, OP time, and hospitalization day. However, the perioperative change in the level of hemoglobin was significantly lower in the energyless myomectomy than in the conventional operation (P < 0.01). Conclusion: Energlyless myomectomy is a feasible method and can have benefits due to no increase in the perioperative complications. It also has low risk of thermal injury to the myometrium or the endometrium. Thus, we expect it to improve the fertility preservation and the outcome of the subsequent pregnancy, but further analysis of the long-term prognosis is needed.
