본 연구는 저장 및 유통과정 중 곶감의 품질 변화를 방지하기 위한 방법으로 기존에 사용되어 왔던 유황 훈증 대체 물질로 이산화염소 훈증 방법의 효과를 확인하고자 하였다. 곶감을 이산화염소 가스 훈증 농도(0, 15, 30, 45 ppm) 및 시간(0, 15, 30, 45 min)에 따라 처리한 후 상온에서 보관하면서 미생물학적 변화, 물성 및 색도를 관찰하였다. 이산화염소 가스 훈증 처리 후 총 호기성 세균과 효모 및 곰팡이 수는 대조구와 비교하였을 때 미생물 수가 감소하였으며, 총 호기성 세균의 저해 효과는 저장기간 동안 지속되었고, 효모 및 곰팡이 수의 경우에도 총 호기성 세균과 유사한 경향을 나타내었다. 곶감의 물성 및 색도는 이산화염소 가스 훈증 농도 및 시간에 의해 영향을 받지 않는 것으로 나타났다. 이산화염소 가스 훈증 처리는 곶감의 저장 중 미생물학적 안전성 확보를 위한 처리 기술로 활용될 수 있을 것으로 기대된다. This study was conducted to investigate the effect of chlorine dioxide fumigation as a substitute for sulfur fumigation which has been used as a method to prevent the quality change of persimmon during storage and distribution process. Dried persimmons were treated with chlorine dioxide gas concentration (0, 15 30, and 45 ppm) and time (0, 15, 30, and 45 min) and microbiological changes, texture properties and color of the treated samples were investigated during storage at room temperature. Total aerobic bacteria, yeast and mold numbers after chlorine dioxide gas fumigation were decreased when compared with the control group. The inhibitory effects of total aerobic bacteria, yeast, and mold were observed during storage. The texture properties and color value of dried persimmons were not affected by chlorine dioxide gas fumigation concentration and time. There was no difference in quality between chlorine dioxide gas fumigation treatment group and control group. These results suggested that chlorine dioxide gas fumigation treatment can be utilized as a processing technique to secure microbiological storage stability of dried persimmons.

This study intends to discover stories and sensibilities connected with characteristics and symbols of the history and culture of Sangju to develop contents about the native foods of Sangju. ‘General Jeong’s Table’, which supplied the energy and nutrition necessary for soldiers during war, is set with Jobap, Patipguk, Euneogui, Baechumoojeon, Kongnamulheojib, Patipnamul, and Munamulsileagideanjangmuchim. ‘Sangjuseong retaking wartime food’, as a kind of ready-to-eat meal, which stresses convenience above everything else, is composed of Konggarujumeokbap, Bbongipjuk, Gamjangajji, and Odigojgammodeumbagitteok for table setting. ‘General Jeong’s liquor table’, which allowed the general to regain his energy or was set to entertain generals of allied forces in the Myeong Dynasty, is formed by Baeksuk, Gojgamssam, Kongjukjijim and Sangsurisul. Efficacies of food materials were analyzed in the Part of Drug Formula of the best-known medical book in Asia. Foods on ‘General Jeong’s Table’ has health efficacies that protect the five viscera and maintain the spleen and stomach.

창원시 소재 단체급식소 4개소에서 사용하는 칼(12 ㎠), 도마(100 ㎠), 고무장갑(손바닥과 손가락 사이)의 표면을 대상으로 ATP Luminometer와 일반세균수용 건조필름을 이용한 미생물 배양법을 함께 적용하여 ATP(RLU)와 APC(CFU)을 측정하였다. 통계분석 결과, 3가지 조리도구 모두에서 ATP(RLU)와 APC(CFU) 간에 유의적인 양의 상관성이 존재하였다. 각 도구별 상관계수는 칼 0.84(p<0.001), 도마 0.79(p<0.001), 고무장갑 0.78(p<0.001)로 나타났다. 본 실험은 단체급식 현장에 적합한 ATP Luminometer 가이드라인을 설정하기에 앞서 실시간적인 표면 위생 모니터링 도구로서의 사용 적합성을 살펴 본 예비실험이며, 도출된 회귀식을 이용하여 도구별 ATP(RLU) 가이드라인을 설정하고 검증할 예정이다. The purpose of this study was to verify feasibility of using a ATP Luminometer, real-time hygiene monitoring tool for food contact surfaces in foodservices. For this, 54 cutting boards, 70 knives, 21 rubber gloves in 4 institutional foodservices were studied. ATP (RLU: relatively light unit) values by ATP Luminometer were compared with APC (CFU: colony forming unit) of swabbing culture method using aerobic count plates of 3M petrifilm. ATP ranged from 0 RLU/㎠ to 64693 RLU/㎠ on knives, from 0.1 RLU/㎠ to 6743.6 RLU/㎠ on cutting boards and from 31 RLU/㎠ to 465635 RLU/㎠ on the rubber gloves. APC ranged from 0 CFU/㎠ to 166667 CFU/㎠ on knives, from 0 CFU/㎠ to 1000 CFU/㎠ on cutting boards and from 0 CFU/㎠ to 730000 CFU/㎠ on the rubber gloves. To express the degree of association between ATP and APC, a linear regression was performed. There were significant positive correlations found between log RLU and log CFU on the knives (r=0.84, p<0.001), the cutting boards (r=0.79, p<0.001), the rubber gloves (r=0.78, p<0.001). Results of this study showed the possibility that ATP bioluminescence technique can be used as the monitoring tool for surface hygiene in foodservices.

This study investigated the quality characteristics of fermented wines using a selected strain to obtain basic data on sugarfree tomato wine production. Alcohol content of the tomato and commercial wine was 8.2~12.9%, whereas tomato wine showed a relatively low alcohol content of 8.2%. For total phenol content, Chile wine showed the highest value of 162.89 mg/100 g, followed by persimmon wine at 122.33 mg/100 g. Tomato wine showed a relatively high total phenol content of 96.57 mg/100 g. In all sections, xylose was not detected, although there were differences in free sugars depending on each product. Acetic and citric acid contents were highest in tomato wine, and the six kinds of commercial wine and tomato wine showed acetic acid content of 800.6 mg/100 g and citric acid content of 1,064.4 mg/100 g. The total free amino acid content was 100.63 mg/100 g in tomato wine, which was 2~3 times higher compared to that in commercial wine (26.33±52.15 mg/100 g).
